Description

DESCRIPTION DESCRIPTION
TITRE : DISPOSITIF D’ECLAIRAGE POUR DEPLACEMENTS URBAINS OU EXTRA-URBAINS TITLE: LIGHTING DEVICE FOR URBAN OR EXTRA-URBAN TRAVEL
DOMAINE TECHNIQUE DE L’INVENTION [0001] Le domaine technique de l’invention est celui des dispositifs d’éclairage pour les déplacements urbains et extra-urbains. TECHNICAL FIELD OF THE INVENTION [0001] The technical field of the invention is that of lighting devices for urban and extra-urban journeys.
[0002] L’invention concerne plus particulièrement un dispositif d’éclairage de sécurité pour déplacement urbains ou extra-urbains, et particulièrement pour casque. ARRIERE PLAN TECHNIQUE [0002] The invention relates more particularly to a safety lighting device for urban or extra-urban travel, and particularly for a helmet. TECHNICAL BACKGROUND
[0003] Dans le cadre de nombreuses activités, ou de nombreux déplacements urbains, le port du casque est souvent obligatoire pour l’utilisateur, ou à défaut d’être obligatoire, fortement conseillé. [0003] In the context of many activities, or many urban trips, wearing a helmet is often mandatory for the user, or if not mandatory, strongly recommended.
[0004] Les casques peuvent comporter en outre un dispositif d’éclairage, notamment à l’arrière, afin d’augmenter la visibilité du porteur vis-à-vis des autres usagers de la route. [0004] Helmets may further include a lighting device, particularly at the rear, in order to increase the wearer's visibility to other road users.
[0005] Ces dispositifs d’éclairage peuvent être intégrés dès la conception du casque ou encore rapportés par l’utilisateur via l’utilisation de moyens de fixation. [0005] These lighting devices can be integrated from the design of the helmet or brought back by the user via the use of fixing means.
[0006] Il existe de nombreux systèmes d’éclairage présentant des caractéristiques différentes en termes d’encombrement, de puissance d’éclairage et d’autonomie. [0006] There are many lighting systems with different characteristics in terms of size, light output and runtime.
[0007] Les dispositifs d’éclairage présentant une grande autonomie de fonctionnement sont généralement soit des dispositifs d’éclairage encombrants, car ils nécessitent l’intégration de batteries endurantes et volumineuses, soit des dispositifs d’éclairage peu lumineux, car ils disposent de moyens d’éclairage peu puissants pour minimiser la consommation électrique et ainsi augmenter l’autonomie de la batterie (i.e. la durée d’utilisation). De plus, les batteries sont généralement de forme parallélépipédique, s’adaptant mal à la courbure des casques. [0008] Ainsi, l’utilisateur doit faire un choix entre un dispositif d’éclairage encombrant, lourd, peu esthétique une fois en position sur un casque, mais lui garantissant un éclairage et une autonomie satisfaisante pour une utilisation quotidienne, ou encore un dispositif d’éclairage léger, de faible encombrement mais présentant en contrepartie une autonomie relativement réduite et/ou un éclairage peu lumineux et difficilement visible de loin ou dans des conditions difficiles. [0007] Lighting devices having a great autonomy of operation are generally either bulky lighting devices, because they require the integration of enduring and bulky batteries, or lighting devices that are not very bright, because they have means low power lighting to minimize power consumption and thus increase battery life (ie duration of use). In addition, the batteries are generally parallelepiped in shape, adapting poorly to the curvature of the helmets. [0008] Thus, the user must make a choice between a bulky, heavy, unattractive lighting device once in position on a helmet, but guaranteeing adequate lighting and autonomy for daily use, or a device light lighting, compact but having in return a relatively reduced autonomy and / or poor lighting and difficult to see from a distance or in difficult conditions.
RESUME DE L’INVENTION SUMMARY OF THE INVENTION
[0009] Dans ce contexte, l’invention vise à proposer un dispositif d’éclairage pour casque permettant de résoudre les inconvénients de l’état de la technique. [0009] In this context, the invention aims to provide a lighting device for a helmet making it possible to overcome the drawbacks of the prior art.
[0010] A cette fin, l’invention concerne un dispositif d’éclairage pour casque comportant un boîtier de protection présentant une forme générale courbe et intégrant : des moyens de stockage d’une énergie électrique ; un élément opto-électronique capable d’émettre de la lumière lorsqu’il est parcouru par un courant électrique ; un module de pilotage pilotant ledit élément opto-électronique et alimenté par lesdits moyens de stockage d’une énergie électrique ; un circuit imprimé reliant électriquement ledit élément opto-électronique et ledit module de pilotage ; ledit circuit imprimé comportant une portion centrale positionnée dans une portion centrale dudit boîtier de protection, ledit élément opto-électronique et ledit module de pilotage étant raccordés au circuit imprimé au niveau de ladite portion centrale, les moyens de stockage d’une énergie électrique comportant une première unité de stockage d’une énergie électrique et une deuxième unité de stockage d’une énergie électrique, ladite première unité de stockage et ladite deuxième unité de stockage étant localisées de part et d’autre de la portion centrale du circuit imprimé. To this end, the invention relates to a helmet lighting device comprising a protective housing having a generally curved shape and incorporating: means for storing electrical energy; an opto-electronic element capable of emitting light when traversed by an electric current; a control module controlling said opto-electronic element and supplied by said means for storing electrical energy; a printed circuit electrically connecting said opto-electronic element and said control module; said printed circuit comprising a central portion positioned in a central portion of said protective housing, said opto-electronic element and said control module being connected to the printed circuit at said central portion, the means for storing electrical energy comprising a first electrical energy storage unit and a second electrical energy storage unit, said first storage unit and said second storage unit being located on either side of the central portion of the printed circuit.
[0011] Ainsi, la nouvelle répartition des moyens de stockage selon l’invention permet de diminuer l’épaisseur du dispositif d’éclairage pour une même autonomie ou puissance délivrable et donc d’obtenir un boîtier courbe avec une épaisseur réduite s’intégrant parfaitement à la courbure du casque. [0011] Thus, the new distribution of the storage means according to the invention makes it possible to reduce the thickness of the lighting device for the same autonomy or deliverable power and therefore to obtain a curved housing with reduced thickness which integrates perfectly with the curvature of the helmet.
[0012] On entend par « le boîtier s’intégre parfaitement à la courbure du casque » que le boîtier s’adapte à la géométrie du casque qui présente une forme courbe pour épouser la forme du crâne de son porteur. Autrement dit, le boîtier épouse la forme du casque, c’est-à-dire que la surface de la face avant du boîtier est sensiblement parallèle à la surface externe du casque destinée à venir en contact avec la face arrière du boîtier. [0012] By "the housing integrates perfectly with the curvature of the helmet" is meant that the housing adapts to the geometry of the helmet which has a curved shape to match the shape of the wearer's skull. In other words, the housing conforms to the shape of the helmet, that is to say that the surface of the front face of the housing is substantially parallel to the outer surface of the helmet intended to come into contact with the rear face of the housing.
[0013] Ainsi, le dispositif d’éclairage selon l’invention permet d’intégrer plus facilement et de manière plus esthétique un dispositif d’éclairage sur un casque. Etant moins en saillie par rapport à la surface du casque, le dispositif d’éclairage assure une meilleure protection en cas de chute notamment en diminuant les accélérations rotationnelles, en réduisant le risque que le casque s’accroche à une surface et en répartissant mieux l’impact sur le casque. De plus, sa compacité le rend compatible avec l’utilisation d’un casque pliable. [0013] Thus, the lighting device according to the invention makes it possible to more easily and more aesthetically integrate a lighting device on a helmet. Being less protruding from the surface of the helmet, the lighting device provides better protection in the event of a fall, in particular by reducing rotational acceleration, reducing the risk of the helmet catching on a surface and distributing it better. impact on the helmet. In addition, its compactness makes it compatible with the use of a folding helmet.
[0014] En outre, l’architecture proposée par l’invention permet d’augmenter la longueur globale du dispositif d’éclairage, rendant plus visible les indicateurs de direction, s’ils sont présents, notamment sur le côté du casque. [0014] In addition, the architecture proposed by the invention makes it possible to increase the overall length of the lighting device, making the direction indicators more visible, if they are present, in particular on the side of the helmet.
[0015] Outre les caractéristiques évoquées dans le paragraphe précédent, le dispositif d’éclairage selon l’invention peut présenter une ou plusieurs caractéristiques complémentaires parmi les suivantes, considérées individuellement ou selon toutes les combinaisons techniquement possibles : ledit élément opto-électronique comporte une première série de diodes électroluminescentes et une deuxième série de diodes électroluminescentes et ledit circuit imprimé comporte deux portions d’extrémité, ladite première série de diodes électroluminescentes étant localisée au niveau de la portion centrale du circuit imprimé et ladite deuxième série de diodes électroluminescentes étant localisée au niveau des portions d’extrémité du circuit imprimé. Ainsi, les séries de diodes électroluminescentes ne sont donc pas situées au niveau des moyens de stockage. Or, comme les moyens de stockage sont les éléments les plus volumineux dans le dispositif d’éclairage, l’épaisseur du dispositif d’éclairage est déterminée par l’épaisseur au niveau des moyens de stockage. Cette disposition des série de diodes électroluminescentes permet donc de ne pas augmenter davantage l’épaisseur du dispositif d’éclairage et ainsi d’assurer une meilleure protection en cas de chute, comme expliqué précédemment ; les diodes électroluminescentes de ladite première série de diodes électroluminescentes présentent une lumière d’émission différente de la lumière d’émission des diodes électroluminescentes de la deuxième série de diodes électroluminescentes ; chaque unité de stockage d’une énergie électrique est localisée entre la portion centrale et une portion d’extrémité du circuit imprimé ; les portions d’extrémité du circuit imprimé sont ménagées aux extrémités du boîtier de protection ; au moins une partie des diodes électroluminescentes de ladite première série de diodes électroluminescentes et/ou au moins une partie des diodes électroluminescentes de ladite deuxième série de diodes électroluminescentes sont positionnées en dessous et/ou au-dessus de chaque unité de stockage ; chaque unité de stockage d’une énergie électrique est raccordée électriquement à la portion centrale du circuit imprimé ; chaque portion d’extrémité est reliée à la portion centrale par un conducteur flexible ; ledit circuit imprimé est un circuit imprimé flexible rigide, ladite portion centrale étant un circuit imprimé rigide et lesdites portions d’extrémité étant des circuits imprimés flexibles raccordées électriquement à la portion centrale ; le dispositif d’éclairage comporte des moyens de fixation comportant une première partie configurée pour être solidarisée sur un casque et une deuxième partie solidaire dudit boîtier de protection, la première partie et la deuxième partie étant configurées pour coopérer et former une liaison amovible. In addition to the characteristics mentioned in the previous paragraph, the lighting device according to the invention may have one or more additional characteristics among the following, considered individually or in all technically possible combinations: said opto-electronic element comprises a first series of light emitting diodes and a second series of light emitting diodes and said printed circuit has two end portions, said first series of light emitting diodes being located at the central portion of the printed circuit and said second series of light emitting diodes being located at end portions of the printed circuit. Thus, the series of light-emitting diodes are therefore not located at the level of the storage means. However, as the means of storage are the larger elements in the lighting device, the thickness of the lighting device is determined by the thickness at the storage means. This arrangement of the series of light-emitting diodes therefore makes it possible not to further increase the thickness of the lighting device and thus to ensure better protection in the event of a fall, as explained previously; the light emitting diodes of said first series of light emitting diodes have an emission light different from the emission light of the light emitting diodes of the second series of light emitting diodes; each electrical energy storage unit is located between the central portion and an end portion of the printed circuit; the end portions of the printed circuit are provided at the ends of the protective case; at least part of the light emitting diodes of said first series of light emitting diodes and / or at least part of the light emitting diodes of said second series of light emitting diodes are positioned below and / or above each storage unit; each electrical energy storage unit is electrically connected to the central portion of the printed circuit; each end portion is connected to the central portion by a flexible conductor; said printed circuit is a rigid flexible printed circuit, said central portion being a rigid printed circuit and said end portions being flexible printed circuits electrically connected to the central portion; the lighting device comprises fixing means comprising a first part configured to be secured to a helmet and a second part secured to said protective housing, the first part and the second part being configured to cooperate and form a removable link.

[0038] De manière générale, on se référera aux quatre figures précédemment décrites pour les différents éléments décrits ci-après. [0037] [Fig 4] illustrates, in a perspective view, the rear or internal face (ie the face intended to be facing the surface of a protective helmet) of the lighting device 100 according to the invention illustrated in [fig 1]. In general, reference will be made to the four figures described above for the various elements described below.
[0039] Sauf précision contraire, un même élément apparaissant sur des figures différentes présente une référence unique. Unless otherwise specified, the same element appearing in different figures has a single reference.
[0040] Le dispositif d’éclairage 100 selon l’invention comporte un boîtier de protection 110, par exemple en matière plastique, formant la partie externe du dispositif d’éclairage 100. [0040] The lighting device 100 according to the invention comprises a protective housing 110, for example of plastic material, forming the outer part of the lighting device 100.
[0041] Le boîtier de protection 110 comporte par exemple deux demi-coques : une première coque avant 111 et une deuxième coque arrière 112. The protective housing 110 comprises for example two half-shells: a first front shell 111 and a second rear shell 112.
[0042] La [fig 10] illustre, selon une vue en perspective, la face avant ou externe de la coque arrière 112 du dispositif d’éclairage 100 selon l’invention illustré à la [fig 1]. [0042] The [Fig 10] illustrates, in a perspective view, the front or outer face of the rear shell 112 of the lighting device 100 according to the invention illustrated in [Fig 1].
[0043] Les deux demi-coques 111, 112 sont configurées pour coopérer et ainsi reconstituer une coque creuse délimitant un espace interne adapté pour intégrer l’ensemble des différents éléments nécessaires au fonctionnement du dispositif d’éclairage 100. The two half-shells 111, 112 are configured to cooperate and thus reconstitute a hollow shell delimiting an internal space suitable for integrating all of the various elements necessary for the operation of the lighting device 100.
[0044] Les deux demi-coques 111 , 112 sont par exemple configurées pour s’emboîter et pour être maintenues solidaire l’une de l’autre. A cet effet, les demi- coques 111 , 112 peuvent comporter des moyens d’indexation, comme par exemple une rainure périphérique configurée pour coopérer avec une languette périphérique, de manière à assurer le bon positionnement des deux demi-coques l’une par rapport à l’autre. Un joint d’étanchéité (non représenté) peut également être positionné à l’interface des deux demi-coques 111 , 112 de manière à assurer l’étanchéité du boîtier de protection 110 vis-à-vis de l’extérieur. [0044] The two half-shells 111, 112 are for example configured to fit together and to be kept integral with one another. To this end, the half-shells 111, 112 may include indexing means, such as for example a peripheral groove configured to cooperate with a peripheral tongue, so as to ensure the correct positioning of the two half-shells relative to one another. to the other. A seal (not shown) can also be positioned at the interface of the two half-shells 111, 112 so as to seal the protective housing 110 from the outside.
[0045] Les deux demi-coques 111 , 112 comportent en outre des moyens pour assurer le maintien et l’assemblage des deux demi-coques 111 , 112. Les moyens de maintien assurant l’assemblage des deux demi-coques sont des moyens ad- hoc permettant de maintenir assemblées les deux demi-coques, par exemple par clipsage, vissage, soudure par ultrason, emboîtement, etc. [0046] Dans l’exemple de réalisation illustré à la [fig 1] et à la [fig 4], les deux demi-coques 111 , 112 sont maintenues solidaires par vissage. La demi-coque arrière 112 présentent des orifices permettant le passage de vis adaptés pour coopérer avec des alésages ménagés au niveau de la demi-coque avant 111. The two half-shells 111, 112 further include means for maintaining and assembling the two half-shells 111, 112. The retaining means ensuring the assembly of the two half-shells are ad means - hoc making it possible to keep the two half-shells assembled, for example by clipping, screwing, ultrasonic welding, interlocking, etc. In the embodiment illustrated in [fig 1] and in [fig 4], the two half-shells 111, 112 are held together by screwing. The rear half-shell 112 have orifices allowing the passage of screws adapted to cooperate with bores formed at the level of the front half-shell 111.
[0047] Selon un autre exemple de réalisation, le boîtier de protection 110 peut être formé par une unique coque creuse principale fermée par un fond amovible, de faible épaisseur, via des moyens connus à cet effet, par exemple par clipsage ou encore vissage. Dans cet exemple de réalisation, le boîtier de protection 110 peut également comporter des moyens d’indexation pour le positionnement du fond amovible. According to another exemplary embodiment, the protective housing 110 may be formed by a single main hollow shell closed by a removable bottom, of small thickness, via means known for this purpose, for example by clipping or even screwing. In this exemplary embodiment, the protective housing 110 may also include indexing means for positioning the removable bottom.
[0048] Le boîtier de protection 110 comporte une face arrière 113 destinée à venir en contact avec la surface externe d’un casque de protection et une face avant 114 formant la partie visible du boîtier de protection 110. La face arrière 113 est avantageusement située au niveau de la coque arrière 112. La face avant 114 est avantageusement située au niveau de la coque avant 111. The protective housing 110 comprises a rear face 113 intended to come into contact with the outer surface of a protective helmet and a front face 114 forming the visible part of the protective housing 110. The rear face 113 is advantageously located at the level of the rear shell 112. The front face 114 is advantageously located at the level of the front shell 111.
[0049] La [fig 9] illustre un casque de protection 10 sur lequel est monté le dispositif d’éclairage 100 selon l’invention. [0049] [Fig 9] illustrates a protective helmet 10 on which is mounted the lighting device 100 according to the invention.
[0050] Comme illustré sur la [fig 9], le boîtier de protection 110 présente une forme générale courbe de manière à s’intégrer au profil courbe d’un casque de protection 10 utilisé notamment pour les déplacements urbains et extra-urbains. La courbure générale du dispositif d’éclairage 100 est plus particulièrement représentée à la [fig 3]. As illustrated in [Fig 9], the protective housing 110 has a generally curved shape so as to fit into the curved profile of a protective helmet 10 used in particular for urban and extra-urban travel. The general curvature of the lighting device 100 is more particularly shown in [fig 3].
[0051] La face avant 114 présente également une forme courbe, sensiblement convexe, par exemple parallèle à la forme sensiblement concave de la face arrière 113 de manière à minimiser l’épaisseur et l’encombrement du dispositif d’éclairage 100. [0051] The front face 114 also has a curved, substantially convex shape, for example parallel to the substantially concave shape of the rear face 113 so as to minimize the thickness and the bulk of the lighting device 100.
[0052] Ainsi, l’épaisseur du dispositif d’éclairage 100 est sensiblement constante. [0053] Le boîtier de protection 110 est par exemple réalisé en polycarbonate ou encore en polypropylène pour résister aux rayonnements extérieurs, comme par exemple aux ultraviolets (UV), et aux chocs. Thus, the thickness of the lighting device 100 is substantially constant. The protective housing 110 is for example made of polycarbonate or even polypropylene to withstand external radiation, such as for example ultraviolet (UV), and shocks.
[0054] Le boîtier de protection 110 peut également être réalisé intégralement ou partiellement dans un matériau souple comme par exemple du silicone ou du polypropylène. L’utilisation de matériau souple par exemple au niveau de certaines zones spécifiques du boîtier de protection 110 permet de pouvoir modifier la courbure générale du boîtier de protection 110 et ainsi présenter une courbure s’adaptant à la géométrie du casque de protection 10. The protective housing 110 can also be made entirely or partially in a flexible material such as for example silicone or polypropylene. The use of flexible material, for example in certain specific areas of the protective casing 110, makes it possible to modify the general curvature of the protective casing 110 and thus present a curvature that matches the geometry of the protective helmet 10.
[0055] La face avant 114 du boîtier de protection 110 présente avantageusement au moins une partie transparente ou translucide permettant la diffusion de la lumière de l’intérieur du boîtier de protection 110 vers l’extérieur du boîtier de protection 110. The front face 114 of the protective casing 110 advantageously has at least one transparent or translucent part allowing the diffusion of light from the inside of the protective casing 110 to the outside of the protective casing 110.
[0056] La partie transparente ou translucide est par exemple réalisée à partir d’un matériau en polymère thermoplastique transparent ou translucide, comme par exemple du PMMA (pour Polyméthacrylate de méthyle), du silicone ou du polypropylène pour une diffusion optimale de la lumière. The transparent or translucent part is for example made from a material of transparent or translucent thermoplastic polymer, such as PMMA (for polymethyl methacrylate), silicone or polypropylene for optimal light diffusion.
[0057] Le boîtier de protection 110 comporte également une ouverture 115, ménagée préférentiellement sur un des côtés du boîtier de protection 110 ou encore au niveau d’une portion supérieure ou d’une portion inférieure du boîtier de protection 110, comme représenté à la [fig 1]. Ce dernier mode de réalisation limite avantageusement les infiltrations d’eau de pluie à l’intérieur du boîtier de protection 110. The protective casing 110 also includes an opening 115, preferably formed on one side of the protective casing 110 or else at an upper portion or a lower portion of the protective casing 110, as shown in [fig 1]. This latter embodiment advantageously limits the infiltration of rainwater inside the protective housing 110.
[0058] L’ouverture 115 permet avantageusement d’avoir accès à un connecteur 160 relié électriquement et physiquement à un circuit imprimé 150 intégré à l’intérieur du boîtier de protection 110. L’ouverture 115 peut coopérer avec un capuchon amovible en matière souple, par exemple en silicone ou en TPU, permettant ainsi d’assurer l’étanchéité du boîtier de protection 110 au niveau de l’ouverture 115 vis-à-vis des conditions extérieures. The opening 115 advantageously allows access to a connector 160 electrically and physically connected to a printed circuit 150 integrated inside the protective housing 110. The opening 115 can cooperate with a removable cap made of flexible material. , for example made of silicone or of TPU, thus making it possible to ensure the sealing of the protective case 110 at the level of the opening 115 vis-à-vis external conditions.
[0059] Le dispositif d’éclairage 100 selon l’invention comporte en outre : un élément opto-électronique 120 capable d’émettre de la lumière lorsqu’il est parcouru par un courant électrique ; un module de pilotage 130 configuré pour piloter l’élément opto électronique ; des moyens de stockage 140 d’une énergie électrique configurés pour alimenter en énergie électrique le module de pilotage 130 et l’élément opto-électronique 120 ; un avertisseur sonore 180. The lighting device 100 according to the invention further comprises: an opto-electronic element 120 capable of emitting light when it is traversed by an electric current; a driving module 130 configured to drive the optoelectronic element; electrical energy storage means 140 configured to supply electrical energy to the control module 130 and the opto-electronic element 120; an audible warning device 180.
[0060] La [fig 11] illustre, selon une vue en perspective, la face avant d’un autre exemple de réalisation du dispositif d’éclairage 100 selon l’invention. [0060] [Fig 11] illustrates, in a perspective view, the front face of another exemplary embodiment of the lighting device 100 according to the invention.
[0061] La [fig 12] illustre, une vue éclatée du dispositif d’éclairage 100 selon l’invention, illustré à la [fig 11]. [0061] [Fig 12] illustrates an exploded view of the lighting device 100 according to the invention, illustrated in [Fig 11].
[0062] Comme représenté sur les [fig 11] et [fig 12], la face avant 114 peut également présenter une partie réfléchissante 301 , formée de catadioptres par exemple, permettant de réfléchir la lumière émise par un véhicule ou toute autre source lumineuse en direction de la face avant 114 du dispositif d’éclairage 100, et d'aider l'utilisateur du casque à être plus visible. La partie réfléchissante 301 est avantageusement placée dans une zone ne recouvrant pas l’élément opto électronique 120. Elle peut par exemple être située en face des moyens de stockage 140 ou d’une portion du circuit imprimé 150. As shown in [fig 11] and [fig 12], the front face 114 may also have a reflecting part 301, formed of reflectors for example, making it possible to reflect the light emitted by a vehicle or any other light source in direction of the front face 114 of the lighting device 100, and to help the user of the helmet to be more visible. The reflecting part 301 is advantageously placed in an area which does not cover the optoelectronic element 120. It can for example be located opposite the storage means 140 or a portion of the printed circuit 150.
[0063] L’élément opto-électronique 120 est par exemple formé par une pluralité de diodes électroluminescentes 120a, 120b (LED en langue anglaise pour Light-Emitting Diode) pouvant émettre une ou plusieurs couleurs. En variante, l’élément opto-électronique 120 comprend un écran à cristaux liquides de préférence combiné avec des diodes électroluminescentes. The opto-electronic element 120 is for example formed by a plurality of light-emitting diodes 120a, 120b (LED in English for Light-Emitting Diode) which can emit one or more colors. Alternatively, the optoelectronic element 120 comprises a liquid crystal display preferably combined with light emitting diodes.
[0064] Les diodes électroluminescents 120a, 120b, le module de pilotage 130, l’avertisseur sonore 180 peuvent être soudés sur le circuit imprimé 150, par exemple selon la technique de composant monté en surface (SMD) ou à l’aide de broches. [0065] Dans l’exemple de réalisation illustré aux [fig 11] et [fig 12], l’élément opto-électronique 120 est constitué de diodes électroluminescentes montées directement sur le substrat d’un circuit imprimé selon la technique de la puce sur circuit imprimé (COB en langue anglaise pour « Chip On Board »). L’élément opto électronique 120 est courbe pour s’adapter à la courbure du boîtier de protection 110, s’adaptant à la géométrie du casque 10. Autrement dit, l’élément opto électronique est sensiblement parallèle à la surface du casque 10 ou de la face avant 114. Le substrat peut être constitué d’une feuille d’aluminium, par exemple de 0.6 mm d’épaisseur, assurant une bonne dissipation thermique. The light-emitting diodes 120a, 120b, the control module 130, the buzzer 180 can be soldered to the printed circuit 150, for example according to the surface-mounted component technique (SMD) or using pins . In the embodiment illustrated in [fig 11] and [fig 12], the opto-electronic element 120 consists of light-emitting diodes mounted directly on the substrate of a printed circuit according to the chip technique on printed circuit (COB in English for "Chip On Board"). The optoelectronic element 120 is curved to adapt to the curvature of the protective housing 110, adapting to the geometry of the helmet 10. In other words, the optoelectronic element is substantially parallel to the surface of the helmet 10 or of the front face 114. The substrate may consist of an aluminum foil, for example 0.6 mm thick, ensuring good heat dissipation.
[0066] Selon une autre variante non représentée, l’élément opto-électronique 120 constitué de diodes électroluminescentes montées sur un circuit selon la technique COB est plat. Il peut être raccordé électriquement au circuit imprimé 150 ou bien faire partie intégrante de celui-ci. [0066] According to another variant not shown, the opto-electronic element 120 consisting of light-emitting diodes mounted on a circuit according to the COB technique is flat. It can be electrically connected to the printed circuit 150 or else form an integral part thereof.
[0067] Dans l’exemple de réalisation illustré à la [fig 2], le dispositif d’éclairage 100 comporte une première série de diodes électroluminescentes référencées 120a émettant, préférentiellement, une lumière de couleur rouge, et une deuxième série de diodes électroluminescentes référencées 120b émettant, préférentiellement, une lumière de couleur jaune ou orange. In the embodiment illustrated in [Fig 2], the lighting device 100 comprises a first series of light-emitting diodes referenced 120a emitting, preferably, a red light, and a second series of light-emitting diodes referenced 120b preferentially emitting a light of yellow or orange color.
[0068] Les diodes électroluminescentes 120b capables d’émettre une couleur orange, ou jaune, sont avantageusement positionnées au niveau des extrémités latérales du dispositif d’éclairage 100 de manière à pouvoir indiquer la direction (gauche ou droite) que l’utilisateur du dispositif d’éclairage 100 va prendre, notamment en combinaison avec un mode de pilotage « clignotant » des diodes électroluminescentes 120b via le module de pilotage 130. The light-emitting diodes 120b capable of emitting an orange or yellow color are advantageously positioned at the level of the lateral ends of the lighting device 100 so as to be able to indicate the direction (left or right) that the user of the device lighting 100 will take, in particular in combination with a "flashing" control mode of the light-emitting diodes 120b via the control module 130.
[0069] Dans l’exemple de réalisation illustré à la [fig 12], l’élément opto électronique 120 du dispositif d’éclairage 100 comporte une unique série de diodes électroluminescentes montée sur un unique circuit imprimé selon la méthode COB et émettant de préférence, une lumière de couleur rouge ou blanche. L’unique série de diodes électroluminescentes est par exemple agencée de manière à former une boucle de forme oblongue ou rectangulaire qui peut être interrompue par exemple dans la zone recouverte par le connecteur 160. [0070] Selon une variante de réalisation, l’élément opto-électronique 120 du dispositif d’éclairage 100 comporte : une série de diodes électroluminescentes montée sur un premier circuit imprimé selon la méthode COB, émettant de préférence, une lumière de couleur rouge, et par exemple agencée de manière à former une première boucle de forme oblongue ou rectangulaire ; une série de diodes électroluminescentes montée sur un deuxième circuit imprimé selon la méthode COB, émettant de préférence, une lumière de couleur blanche, et par exemple agencée de manière à former une deuxième boucle de forme oblongue ou rectangulaire, la deuxième boucle épousant par exemple les contours de la première boucle, le deuxième circuit imprimé étant parallèle au premier circuit imprimé. In the embodiment illustrated in [Fig 12], the opto-electronic element 120 of the lighting device 100 comprises a single series of light-emitting diodes mounted on a single printed circuit according to the COB method and preferably emitting , a red or white light. The single series of light-emitting diodes is for example arranged so as to form a loop of oblong or rectangular shape which can be interrupted for example in the zone covered by the connector 160. According to an alternative embodiment, the opto-electronic element 120 of the lighting device 100 comprises: a series of light-emitting diodes mounted on a first printed circuit according to the COB method, preferably emitting a light of red color, and for example arranged so as to form a first loop of oblong or rectangular shape; a series of light-emitting diodes mounted on a second printed circuit according to the COB method, preferably emitting a white light, and for example arranged so as to form a second loop of oblong or rectangular shape, the second loop for example following the contours of the first loop, the second printed circuit being parallel to the first printed circuit.
[0071] L’élément opto-électronique 120 du dispositif d’éclairage 100 peut comporter en outre deux séries de diodes électroluminescentes émettant, de préférence, une lumière de couleur orange, situées respectivement au niveau de chaque extrémité du boîtier de protection 110 et par exemple agencées de manière à former une forme en U ou en V. Dans ce cas, lesdites deux séries de diodes électroluminescentes peuvent épouser les contours de la première boucle ou de la deuxième boucle situés au niveau de l’extrémité du boîtier de protection 110 correspondante. The opto-electronic element 120 of the lighting device 100 may further include two series of light emitting diodes emitting, preferably, an orange light, located respectively at each end of the protective housing 110 and by example arranged so as to form a U or V shape. In this case, said two series of light emitting diodes can follow the contours of the first loop or of the second loop located at the end of the corresponding protective housing 110 .
[0072] Selon une autre variation de réalisation, l’élément opto-électronique 120 du dispositif d’éclairage 100 comporte cinq séries de diodes électroluminescentes, chacune montée sur un circuit selon la méthode COB, par exemple : According to another variation of embodiment, the opto-electronic element 120 of the lighting device 100 comprises five series of light-emitting diodes, each mounted on a circuit according to the COB method, for example:
Deux séries primaires de diodes électroluminescentes émettant de préférence, une lumière de couleur rouge ou blanche, situées respectivement au niveau de chaque extrémité du boîtier de protection et par exemple agencées de manière à former une forme en U ou en V;Two primary series of light-emitting diodes preferably emitting a light of red or white color, located respectively at each end of the protective case and for example arranged so as to form a U or V shape;
Deux séries secondaires de diodes électroluminescentes émettant de préférence, une lumière de couleur orange, situées respectivement au niveau de chaque extrémité du boîtier de protection et par exemple agencées de manière à former une forme en U ou en V, chaque série secondaire de diodes électroluminescentes épousant par exemple la forme d’une série primaire de diodes électroluminescentes différente ;Two secondary series of light-emitting diodes preferably emitting an orange-colored light, located respectively at each end of the protective housing and for example arranged so as to form a U or V shape, each secondary series of light-emitting diodes for example taking the shape of a different primary series of light-emitting diodes;
Une série de diodes électroluminescentes émettant de préférence, une lumière de couleur rouge ou blanche, reliant les deux séries primaires de diodes électroluminescentes et les deux séries secondaires de diodes électroluminescentes, par exemple de manière que l’ensemble des diodes électroluminescentes forme une boucle de forme oblongue, située au moins en partie au niveau de la portion centrale du boîtier de protection. A series of light-emitting diodes preferably emitting a light of red or white color, connecting the two primary series of light-emitting diodes and the two secondary series of light-emitting diodes, for example so that all of the light-emitting diodes form a shaped loop oblong, located at least partly at the level of the central portion of the protective housing.
[0073] Le module de pilotage 130 est par exemple un dispositif intelligent configuré pour permettre un pilotage de la puissance d’éclairage de l’élément opto-électronique 120, la ou les couleur(s) de l’éclairage de l’élément opto électronique 120, notamment avec l’utilisation de diodes électroluminescentes présentant plusieurs couleurs d’émission, le mode d’éclairage (continu ou clignotant), etc. The control module 130 is for example an intelligent device configured to allow control of the lighting power of the opto-electronic element 120, the color (s) of the lighting of the opto element electronic 120, in particular with the use of light-emitting diodes having several emission colors, the lighting mode (continuous or flashing), etc.
[0074] L’ensemble des éléments (élément opto-électronique 120, module de pilotage 130) sont raccordés électriquement et physiquement sur un circuit imprimé 150. [0075] Le circuit imprimé 150 présente une portion centrale 151 et deux portions d’extrémité 152 situées de part et d’autre de la portion centrale 151 et raccordées électriquement à la portion centrale 151. All the elements (opto-electronic element 120, control module 130) are electrically and physically connected to a printed circuit 150. The printed circuit 150 has a central portion 151 and two end portions 152 located on either side of the central portion 151 and electrically connected to the central portion 151.
[0076] La portion centrale 151 du circuit imprimé 150 comporte avantageusement : - le module de pilotage 130, une interface Homme-Machine 170, par exemple un commutateur tactile ou un interrupteur de type bouton-poussoir, permettant à un utilisateur d’allumer ou d’éteindre le dispositif d’éclairage 100, ou encore de choisir un mode de fonctionnement dudit dispositif d’éclairage 100 ; le connecteur 160 permettant le branchement d’une alimentation ou d’un dispositif de recharge des moyens de stockage 140 d’une énergie électrique ; une première série de diodes électroluminescentes 120a, émettant par exemple une lumière rouge. The central portion 151 of the printed circuit 150 advantageously comprises: the control module 130, a Man-Machine interface 170, for example a tactile switch or a push-button type switch, allowing a user to switch on or off. to switch off the lighting device 100, or else to choose an operating mode of said lighting device 100; the connector 160 allowing the connection of a power supply or of a device for recharging the means 140 for storing electrical energy; a first series of light-emitting diodes 120a, for example emitting red light.
[0077] Les portions d’extrémité 152, de préférence de plus petites dimensions que la portion centrale 151 , comporte avantageusement au moins une diode électroluminescente d’une deuxième série 120b, émettant par exemple une lumière orange ou jaune. The end portions 152, preferably of smaller dimensions than the central portion 151, advantageously comprises at least one light-emitting diode of a second series 120b, for example emitting an orange or yellow light.
[0078] Selon un premier exemple de réalisation, la portion centrale 151 ainsi que les portions d’extrémité 152 du circuit imprimé 150 sont rigides, c’est-à-dire réalisées à partir d’une plaque de matériau isolant rigide, par exemple en résine époxy. Les portions d’extrémité 152 sont alors reliées électriquement à la portion centrale 151 via des conducteurs électriques, par exemple par des câbles conducteurs ou des nappes multibrins. Les conducteurs électriques, de préférence flexibles, étant de faible épaisseur, ils peuvent se superposer à l’épaisseur des moyens de stockage 140 d’énergie électrique sans augmenter sensiblement l’épaisseur globale du dispositif d’éclairage 100. Les conducteurs électriques peuvent aussi cheminer au-dessus ou au-dessous des moyens de stockage 140, réduisant encore l’épaisseur. According to a first exemplary embodiment, the central portion 151 as well as the end portions 152 of the printed circuit 150 are rigid, that is to say made from a plate of rigid insulating material, for example in epoxy resin. The end portions 152 are then electrically connected to the central portion 151 via electrical conductors, for example by conductor cables or multi-stranded layers. The electrical conductors, preferably flexible, being thin, they can be superimposed on the thickness of the electrical energy storage means 140 without significantly increasing the overall thickness of the lighting device 100. The electrical conductors can also run. above or below the storage means 140, further reducing the thickness.
[0079] Selon une deuxième variante de réalisation, le circuit imprimé 150 est un circuit imprimé flexible rigide, également appelé « flex-rigide », formant une combinaison de circuits imprimés rigides « standards » et de circuits imprimés flexibles présentant les avantages de chacun et apportant une solution avantageuse en réponse à un besoin d’espace et de fiabilité. Les circuits imprimés flexibles peuvent être réalisés à partir d’un substrat en matière plastique de fine épaisseur, de type haute performance, comme par exemple le polyimide ou encore le polyétheréthercétone (PEEK). According to a second variant embodiment, the printed circuit 150 is a rigid flexible printed circuit, also called "flex-rigid", forming a combination of "standard" rigid printed circuits and flexible printed circuits having the advantages of each and providing an advantageous solution in response to a need for space and reliability. Flexible printed circuits can be made from a thin plastic substrate, high performance type, such as polyimide or polyetheretherketone (PEEK).
[0080] Ainsi, dans cette deuxième variante de réalisation, le circuit imprimé 150 comporte des portions rigides (la portion centrale 151 et les portions d’extrémité 152) sur lesquelles les différents composants électroniques sont solidarisés, les différentes portions étant reliées électriquement par des circuits flexibles. Thus, in this second variant embodiment, the printed circuit 150 comprises rigid portions (the central portion 151 and the end portions 152) on which the various electronic components are joined together, the various portions being electrically connected by flexible circuits.
[0081] Ce deuxième exemple de réalisation permet d’obtenir une meilleure fiabilité par rapport au premier exemple de réalisation, décrit précédemment, notamment en supprimant la connectique entre les différentes portions et donc les étapes de soudure supplémentaires. This second exemplary embodiment makes it possible to obtain better reliability compared to the first exemplary embodiment, described above, in particular by eliminating the connection between the different portions and therefore the additional welding steps.
[0082] De plus, les composants électroniques sont montés sur des supports rigides ce qui permet d’assurer une plus grande fiabilité dans le temps des connections électriques. [0082] In addition, the electronic components are mounted on rigid supports which makes it possible to ensure greater reliability over time of the electrical connections.
[0083] Ce deuxième exemple de réalisation permet également de réduire les coûts de fabrication en simplifiant les étapes de montage. This second exemplary embodiment also makes it possible to reduce manufacturing costs by simplifying the assembly steps.
[0084] Dans un troisième exemple de réalisation, la portion centrale 151 est rigide et les portions d’extrémité 152 sont flexibles et directement reliées, ou soudées, à la portion centrale 151. Les portions d’extrémité 152 étant de faible épaisseur, elles peuvent se superposer aux moyens de stockage 140 d’énergie électrique sans augmenter sensiblement l’épaisseur du dispositif d’éclairage 100. Dans cet exemple de réalisation, on combine les avantages de robustesse et de compacité. Comme illustré sur la [fig 2], les portions d’extrémité 152 sont avantageusement de forme allongée pour que les diodes électroluminescentes 120b soient positionnées à l’extrémité des unités de stockage 141 , 142. In a third exemplary embodiment, the central portion 151 is rigid and the end portions 152 are flexible and directly connected, or welded, to the central portion 151. The end portions 152 being of small thickness, they can be superimposed on the electrical energy storage means 140 without significantly increasing the thickness of the lighting device 100. In this exemplary embodiment, the advantages of robustness and compactness are combined. As illustrated in [Fig 2], the end portions 152 are advantageously elongated in shape so that the light emitting diodes 120b are positioned at the end of the storage units 141, 142.
[0085] Dans un quatrième exemple de réalisation, le circuit imprimé 150 est entièrement un circuit flexible, ce qui permet d’optimiser davantage la compacité de l’architecture électronique du dispositif d’éclairage 100 et aussi de réduire le nombre de soudures. In a fourth exemplary embodiment, the printed circuit 150 is entirely a flexible circuit, which makes it possible to further optimize the compactness of the electronic architecture of the lighting device 100 and also to reduce the number of welds.
[0086] Selon une autre variante, le circuit imprimé 150 ne comporte pas de portions d’extrémité 152 mais uniquement une portion centrale 151. Dans cette variante de réalisation, l’élément opto-électronique 120, avantageusement raccordé au niveau de la portion centrale 151 , par exemple par soudure, peut être formé par une unique série de diodes électroluminescentes référencées 120a émettant, préférentiellement, une lumière de couleur rouge. L’élément opto électronique 120 peut aussi être formé par l’association d’une première série de diodes électroluminescentes référencées 120a émettant, préférentiellement, une lumière de couleur rouge, et une deuxième série de diodes électroluminescentes référencées 120b émettant, préférentiellement, une lumière de couleur jaune ou orange, la deuxième série de diodes électroluminescentes référencées 120b étant avantageusement localisée au niveau des extrémités latérales de la portion centrale 151 du circuit imprimé 150. According to another variant, the printed circuit 150 does not include end portions 152 but only a central portion 151. In this variant embodiment, the opto-electronic element 120, advantageously connected at the level of the central portion 151, for example by soldering, can be formed by a single series of light-emitting diodes referenced 120a, preferentially emitting a light of red color. The optoelectronic element 120 can also be formed by the association of a first series of light-emitting diodes referenced 120a emitting, preferentially, a light of red color, and a second series of light-emitting diodes referenced 120b emitting, preferably, a light of yellow or orange color, the second series of light-emitting diodes referenced 120b being advantageously located at the ends sides of the central portion 151 of the printed circuit 150.
[0087] Les moyens de stockage 140 d’une énergie électrique sont avantageusement formés par l’association de plusieurs unités de stockage 141 ,142 d’une énergie électrique, par exemple une première unité de stockage 141 et une deuxième unité de stockage 142, indépendantes physiquement l’une de l’autre et raccordées électriquement aux composants électroniques, par exemple via la portion centrale 151 du circuit imprimé 150, de préférence au moyen de soudures ou de connecteurs électriques. The means 140 for storing electrical energy are advantageously formed by the association of several storage units 141, 142 for electrical energy, for example a first storage unit 141 and a second storage unit 142, physically independent of one another and electrically connected to the electronic components, for example via the central portion 151 of the printed circuit 150, preferably by means of solders or electrical connectors.
[0088] Les unités de stockage 141 , 142 d’une énergie électrique sont par exemple des batteries, des piles, ou encore des piles boutons, pouvant être rechargeables ou non. Les unités de stockage 141 , 142 peuvent être de sensiblement de forme parallélépipédique ou cylindrique. The storage units 141, 142 of electrical energy are, for example, batteries, cells, or even button cells, which may or may not be rechargeable. The storage units 141, 142 can be substantially parallelepipedal or cylindrical in shape.
[0089] Selon un exemple de mode de réalisation dans lequel, les unités de stockage 141 , 142 ne sont pas rechargeables, le boîtier de protection 110 comporte avantageusement des capots amovibles permettant d’ouvrir et de fermer aisément le boîtier de protection 110. Ainsi, il est possible d’avoir accès rapidement et facilement, sans l’utilisation d’un outil spécifique, à la zone des unités de stockage 141 , 142. Les capots amovibles sont par exemple retirables manuellement par un utilisateur et maintenus en position sur le boîtier de protection 110 par exemple par un système de clips. According to an exemplary embodiment in which the storage units 141, 142 are not rechargeable, the protective case 110 advantageously comprises removable covers making it possible to easily open and close the protective case 110. Thus, , it is possible to have quick and easy access, without the use of a specific tool, to the area of the storage units 141, 142. The removable covers can for example be removed manually by a user and held in position on the protective housing 110 for example by a system of clips.
[0090] Avantageusement, les unités de stockage 141 , 142 sont des batteries qu’il est possible de recharger via la connexion d’une alimentation électrique externe au niveau du connecteur 160. La gestion de l’alimentation et de la recharge des unités de stockage 141 , 142 sont réalisées et pilotées par le module de pilotage 130. [0091] Le connecteur 160 est par exemple un port USB Micro ou un port USB Type-C. Advantageously, the storage units 141, 142 are batteries that it is possible to recharge via the connection of an external power supply at the level of the connector 160. The management of the power supply and of the recharging of the charging units. storage 141, 142 are produced and controlled by the control module 130. The connector 160 is for example a Micro USB port or a USB Type-C port.
[0092] Les unités de stockage 141 , 142 sont avantageusement réparties de part et d’autre de la portion centrale 151 du circuit imprimé 150 du dispositif d’éclairage 100. The storage units 141, 142 are advantageously distributed on either side of the central portion 151 of the printed circuit 150 of the lighting device 100.
[0093] Avantageusement, les unités de stockage 141 , 142 sont positionnées dans une région proche des extrémités latérales du boîtier de protection 110 du dispositif d’éclairage 100. Advantageously, the storage units 141, 142 are positioned in a region close to the lateral ends of the protective housing 110 of the lighting device 100.
[0094] Les unités de stockage 141 , 142 sont positionnées entre la portion centrale 151 et une portion d’extrémité 152 du circuit imprimé 150. Ainsi, il est possible d’optimiser l’épaisseur de l’architecture interne des composants électroniques du dispositif d’éclairage 100, et donc minimiser l’épaisseur globale du dispositif d’éclairage 100 car les unités de stockage 141 , 142 sont localisées dans des zones dépourvues de composants électroniques. The storage units 141, 142 are positioned between the central portion 151 and an end portion 152 of the printed circuit 150. Thus, it is possible to optimize the thickness of the internal architecture of the electronic components of the device. lighting 100, and therefore minimize the overall thickness of the lighting device 100 because the storage units 141, 142 are located in areas devoid of electronic components.
[0095] Selon un mode de réalisations, les moyens de stockage 140 sont formés de plus de deux unités de stockage, les moyens de stockage 140 étant répartis sur la longueur du dispositif d’éclairage 100. According to one embodiment, the storage means 140 are formed from more than two storage units, the storage means 140 being distributed over the length of the lighting device 100.
[0096] Les unités de stockage 141 , 142 sont raccordées électriquement au module de pilotage 130 via le circuit imprimé 150, et plus particulièrement via la portion centrale 151. The storage units 141, 142 are electrically connected to the control module 130 via the printed circuit 150, and more particularly via the central portion 151.
[0097] Les unités de stockage 141, 142 peuvent être des accumulateurs lithium et plus particulièrement des accumulateurs lithium-ion. The storage units 141, 142 can be lithium accumulators and more particularly lithium-ion accumulators.
[0098] Les unités de stockage 141 , 142 présentent par exemple une capacité de 200 mAh pour une dimension de 25x20x4 mm. The storage units 141, 142 have for example a capacity of 200 mAh for a dimension of 25x20x4 mm.
[0099] Ainsi, pour une même capacité de stockage d’énergie électrique, et une même autonomie que les dispositifs d’éclairage de l’état de la technique, le dispositif d’éclairage 100 selon l’invention propose de réduire l’encombrement global du dispositif d’éclairage 100 en divisant les moyens de stockage d’énergie électrique en plusieurs unités de stockage 141 , 142 de plus petites dimensions et en répartissant les différentes unités de stockage 141 , 142 à différents endroits spécifiques à l’intérieur du boîtier de protection 110, de préférence sans superposition avec d’autres composants électroniques du dispositif d’éclairage 100. Thus, for the same electrical energy storage capacity, and the same autonomy as the lighting devices of the state of the art, the lighting device 100 according to the invention proposes to reduce the bulk. overall of the lighting device 100 by dividing the electrical energy storage means into several storage units 141, 142 of smaller dimensions and by distributing the different storage units 141, 142 at different locations specific inside the protective housing 110, preferably without superimposition with other electronic components of the lighting device 100.
[00100] L’utilisation de plusieurs unités de stockage 141 , 142 au lieu et place d’une unique unité de stockage, par exemple centrée dans le dispositif d’éclairage 100, permet de diminuer l’encombrement de chaque unité de stockage 141 , 142 et de répartir l’encombrement sur la longueur du dispositif d’éclairage 100, minimisant par conséquent l’épaisseur globale du dispositif d’éclairage 100, par rapport aux dispositifs d’éclairage de l’état de la technique. De plus, l’utilisation d’une unique unité de stockage positionnée au niveau d’un côté du dispositif d’éclairage et d’un circuit imprimé positionnée au niveau du côté opposé du dispositif d’éclairage rend également le dispositif d’éclairage déséquilibré. Ainsi, il est courant de constater dans les dispositifs d’éclairage de l’état de la technique que le poids n’est pas équilibré et que les fonctions ne sont pas symétriques. The use of several storage units 141, 142 instead of a single storage unit, for example centered in the lighting device 100, makes it possible to reduce the size of each storage unit 141, 142 and to distribute the bulk over the length of the lighting device 100, consequently minimizing the overall thickness of the lighting device 100, compared to the lighting devices of the state of the art. In addition, the use of a single storage unit positioned at one side of the lighting device and a printed circuit positioned at the opposite side of the lighting device also makes the lighting device unbalanced. . Thus, it is common to find in lighting devices of the prior art that the weight is not balanced and that the functions are not symmetrical.
[00101] Avantageusement, le positionnement des unités de stockage 141 , 142 de manière symétrique par rapport à la portion centrale du dispositif d’éclairage 100 permet également d’équilibrer le poids du dispositif d’éclairage 100 et aussi d’obtenir une apparence symétrique. Advantageously, the positioning of the storage units 141, 142 symmetrically with respect to the central portion of the lighting device 100 also makes it possible to balance the weight of the lighting device 100 and also to obtain a symmetrical appearance. .
[00102] Avantageusement, les diodes électroluminescentes 120a, 120b sont positionnées de part et d’autre des unités de stockage 141 , 142 de sorte que les diodes électroluminescentes 120b destinées à indiquer le changement de direction de l’utilisateur se retrouvent aux extrémités gauche et droite du dispositif d’éclairage 100. Un tel positionnement permet ainsi de limiter le risque de confusion entre l’indication de direction gauche et droite. Avantageusement, le boîtier de protection 110 présente une forme allongée par rapport à sa hauteur pour bien distinguer l’indication d’une direction gauche ou droite par les diodes électroluminescentes 120b en les éloignant. Advantageously, the light-emitting diodes 120a, 120b are positioned on either side of the storage units 141, 142 so that the light-emitting diodes 120b intended to indicate the change of direction of the user are found at the left ends and right of the lighting device 100. Such a positioning thus makes it possible to limit the risk of confusion between the indication of left and right direction. Advantageously, the protective housing 110 has an elongated shape with respect to its height in order to clearly distinguish the indication of a left or right direction by the light-emitting diodes 120b by moving them away.
[00103] Le dispositif d’éclairage 100 présente une forme allongée de manière à s’étendre sur une portion étendue au niveau de la surface du casque de protection 10 notamment pour améliorer la visibilité latérale du dispositif d’éclairage 100, et notamment de l’indication de direction. Le boîtier de protection 110 forme avantageusement un arc de cercle vu de dessus par rapport au casque de protection 10. La courbure du dispositif d’éclairage 100 participe ainsi à sa visibilité latérale. The lighting device 100 has an elongated shape so as to extend over an extended portion at the level of the surface of the protective helmet 10 in particular to improve the lateral visibility of the lighting device 100, and in particular of the direction indication. The protective housing 110 forms advantageously an arc of a circle seen from above with respect to the protective helmet 10. The curvature of the lighting device 100 thus contributes to its lateral visibility.
[00104] Selon une autre variante, au moins une partie des diodes électroluminescentes 120a et/ou 120b sont positionnées au-dessus et/ou en dessous des unités de stockage 141 , 142 minimisant ainsi l’épaisseur globale du dispositif d’éclairage 100. Cette construction peut permettre de ne pas interrompre longitudinalement les diodes électroluminescentes 120a et/ou 120b au niveau des unités de stockage 141 , 142. Selon ce mode de réalisation, la portion centrale 151 et/ou la portion d’extrémité 152 du circuit imprimé peut se prolonger au-dessus et/ou au-dessous des unités de stockage 141 , 142. Avantageusement, le dispositif d’éclairage 100 comporte un cache positionné entre la demi-coque avant 111 et le circuit imprimé 150 et/ou les moyens de stockage 140. Ainsi, l’intérieur du dispositif d’éclairage 100 est moins visible par transparence de la demi-coque avant 111. Dans ce cas, le cache peut être muni d’ouvertures pour laisser passer la lumière des diodes électroluminescentes 120a, 120b. [00104] According to another variant, at least part of the light-emitting diodes 120a and / or 120b are positioned above and / or below the storage units 141, 142 thus minimizing the overall thickness of the lighting device 100. This construction can make it possible not to interrupt the light-emitting diodes 120a and / or 120b longitudinally at the level of the storage units 141, 142. According to this embodiment, the central portion 151 and / or the end portion 152 of the printed circuit can extend above and / or below the storage units 141, 142. Advantageously, the lighting device 100 comprises a cover positioned between the front half-shell 111 and the printed circuit 150 and / or the storage means 140. Thus, the interior of the lighting device 100 is less visible by transparency of the front half-shell 111. In this case, the cover may be provided with openings to allow the light of the light-emitting diodes 120a, 120b to pass through. .
[00105] Dans l’exemple de réalisation illustré aux [fig 11] et [fig 12], l’élément opto-électronique 120 est positionné autour, c’est-à-dire à l’extérieur, des unités de stockage 141, 142 et avantageusement du circuit imprimé 150. L’élément opto électronique peut ainsi former une boucle de forme oblongue ou rectangulaire par exemple. L’avantage de cette construction est que l’élément opto-électronique 120 ne se superpose par aux unités de stockage 141, 142 qui sont généralement encombrantes en termes d’épaisseur. De plus cette construction permet d’améliorer la visibilité du dispositif d’éclairage 100 en maximisant la surface délimitée par la boucle de l’élément opto-électronique 120. In the exemplary embodiment illustrated in [fig 11] and [fig 12], the opto-electronic element 120 is positioned around, that is to say outside, the storage units 141, 142 and advantageously of the printed circuit 150. The optoelectronic element can thus form a loop of oblong or rectangular shape, for example. The advantage of this construction is that the opto-electronic element 120 does not overlap with the storage units 141, 142 which are generally bulky in terms of thickness. In addition, this construction improves the visibility of the lighting device 100 by maximizing the area delimited by the loop of the opto-electronic element 120.
[00106] Les unités de stockage 141 , 142 d’une énergie électrique sont avantageusement connectées électriquement en série ou en parallèle et pilotées par le module de pilotage 130. The storage units 141, 142 of electrical energy are advantageously electrically connected in series or in parallel and controlled by the control module 130.
[00107] L’avertisseur sonore 180 permet notamment d’indiquer le fonctionnement des diodes électroluminescentes 120b en mode clignotant, ou encore la navigation entre différents modes de pilotage. La puissance d’émission de l’avertisseur sonore 180 peut varier selon le bruit ambiant de manière à ce que l’utilisateur du dispositif d’éclairage 100 l’entende quel que soit l’environnement extérieur. [00107] The buzzer 180 makes it possible in particular to indicate the operation of the light-emitting diodes 120b in flashing mode, or alternatively the navigation between different piloting modes. Transmitting power of the buzzer 180 may vary according to the ambient noise so that the user of the lighting device 100 can hear it regardless of the external environment.
[00108] Avantageusement, l’avertisseur sonore 180 est localisé dans la partie centrale du dispositif d’éclairage 100, présentant la plus grande distance entre le circuit imprimé 150 et le boîtier de protection 110. Ainsi, il est possible d’intégrer un avertisseur sonore 180 ayant des dimensions plus importantes, et donc plus puissant. Advantageously, the buzzer 180 is located in the central part of the lighting device 100, having the greatest distance between the printed circuit 150 and the protective housing 110. Thus, it is possible to integrate a warning device sound 180 having larger dimensions, and therefore more powerful.
[00109] En outre, le dispositif d’éclairage 100 peut comporter : - un module de communication, par exemple de type radio communication, Bluetooth, Wifi, permettant d’appairer par exemple le dispositif d’éclairage 100 avec une télécommande pour contrôler via une Interface Homme/Machine distante le type et/ou le mode d’éclairage du dispositif d’éclairage 100 et notamment indiquer une direction ; un accéléromètre de 1 à 3 axes pour la détection des variations de vitesses, par exemple pour détecter une accélération ou une décélération de l’utilisateur et ainsi modifier le type et/ou le mode d’éclairage en conséquence ; - un gyromètre 3 axes pour la mesure de la vitesse angulaire par exemple pour détecter une chute de l’utilisateur et ainsi modifier le type et/ou le mode d’éclairage en conséquence ; des moyens logiciels associés à un microphone configurés pour permettre une reconnaissance vocale et pour contrôler le type et/ou le mode d’éclairage du dispositif d’éclairage 100 ; un dispositif de guidage GPS interagissant avec le module de pilotage 130 pour modifier le mode et/ou le type d’éclairage du dispositif d’éclairage 100 et notamment indiquer un changement de direction. [00109] In addition, the lighting device 100 may comprise: a communication module, for example of the radio communication, Bluetooth, Wifi type, making it possible to pair, for example, the lighting device 100 with a remote control to control via a Human / Machine Interface remote from the type and / or mode of lighting of the lighting device 100 and in particular to indicate a direction; a 1 to 3-axis accelerometer for detecting speed variations, for example to detect user acceleration or deceleration and thus change the type and / or mode of lighting accordingly; - a 3-axis gyrometer for measuring angular speed, for example to detect a user fall and thus modify the type and / or mode of lighting accordingly; software means associated with a microphone configured to allow voice recognition and to control the type and / or mode of lighting of the lighting device 100; a GPS guidance device interacting with the control module 130 to modify the mode and / or the type of lighting of the lighting device 100 and in particular to indicate a change of direction.
[00110] Pour augmenter la possibilité de variation de courbure du dispositif d’éclairage 100, le boîtier de protection 110 peut aussi présenter longitudinalement une ou plusieurs zones d’articulation faisant office d’articulation pour modifier la courbure du dispositif d’éclairage 100 et ainsi lui permettre de mieux épouser la forme du casque de protection 10. Les zones d’articulation sont des zones d’épaisseur variable, et notamment des zones présentent une épaisseur plus faible. To increase the possibility of variation in curvature of the lighting device 100, the protective housing 110 may also have longitudinally one or more articulation zones acting as articulation to modify the curvature of the lighting device 100 and thus allow it to better match the shape of the protective helmet 10. The articulation zones are zones of variable thickness , and in particular areas have a lower thickness.
[00111] La [fig 7] est une vue en coupe d’un exemple de réalisation du dispositif d’éclairage 100 selon l’invention, présentant des zones d’articulation. [00111] [Fig 7] is a sectional view of an exemplary embodiment of the lighting device 100 according to the invention, having articulation zones.
[00112] La [fig 8] illustre, selon une vue en perspective, la face arrière ou interne du dispositif d’éclairage 100 selon l’invention, illustré à la [fig 7] [00112] [Fig 8] illustrates, in a perspective view, the rear or internal face of the lighting device 100 according to the invention, illustrated in [Fig 7]
[00113] Dans l’exemple de réalisation illustré à la [fig 7] et à la [fig 8], le boîtier de protection 110 présente deux zones d’articulation localisées entre les différents éléments électroniques intégrés à l’intérieur du boîtier de protection 110. Plus précisément, chaque zone d’articulation est localisée entre une portion centrale 151 du circuit imprimé 150 et une unité de stockage 141 , 142. Chaque zone d’articulation est constituée d’une rainure 118, ce qui a pour conséquence que l’épaisseur du boîtier de protection 110 est réduite au niveau des zones d’articulation. Dans cet exemple de réalisation, les moyens de fixation sont par exemple un adhésif double face solidaire de la face arrière 113 du dispositif d’éclairage 100. In the exemplary embodiment illustrated in [fig 7] and in [fig 8], the protective casing 110 has two articulation zones located between the various electronic elements integrated inside the protective casing 110. More precisely, each articulation zone is located between a central portion 151 of the printed circuit 150 and a storage unit 141, 142. Each articulation zone consists of a groove 118, which has the consequence that the The thickness of the protective housing 110 is reduced at the level of the articulation zones. In this exemplary embodiment, the fixing means are for example a double-sided adhesive integral with the rear face 113 of the lighting device 100.
[00114] Le dispositif d’éclairage 100 selon l’invention est par exemple un dispositif d’éclairage avant ou arrière pour casque de protection 10. [00114] The lighting device 100 according to the invention is, for example, a front or rear lighting device for a protective helmet 10.
[00115] Par exemple, lorsque le dispositif d’éclairage 100 est un dispositif d’éclairage destiné à être positionné en avant d’un casque de protection 10, celui- ci peut comporter des diodes électroluminescentes aptes à émettre une lumière différente d’une lumière rouge, par exemple préférentiellement bleu, jaune ou encore blanche. [00115] For example, when the lighting device 100 is a lighting device intended to be positioned in front of a protective helmet 10, the latter may include light-emitting diodes capable of emitting a light different from a red light, for example preferably blue, yellow or even white.
[00116] Le dispositif d’éclairage 100 comporte également des moyens de fixation permettant de solidariser le dispositif d’éclairage 100 sur un casque de protection 10, comme illustré sur la [fig 9]. [00117] Toutefois, le dispositif d’éclairage 100 selon l’invention peut également comporter des moyens de fixation configurés pour permettre une fixation, temporaire ou définitive, sur un support, tel qu’un sac, une casquette, un chapeau, un vêtement, un véhicule motorisé ou non comme par exemple une bicyclette, une trottinette, une moto. Il peut aussi être fixé directement sur la tête au moyen d’un bandeau. [00116] The lighting device 100 also comprises fixing means allowing the lighting device 100 to be secured to a protective helmet 10, as illustrated in [FIG. 9]. However, the lighting device 100 according to the invention can also include fixing means configured to allow fixing, temporary or definitive, on a support, such as a bag, a cap, a hat, a piece of clothing. , a motorized vehicle or not such as for example a bicycle, a scooter, a motorbike. It can also be attached directly to the head with a headband.
[00118] Les moyens de fixation sont par exemple un adhésif double face solidaire de la face arrière 113 du dispositif d’éclairage 100. The fixing means are for example a double-sided adhesive integral with the rear face 113 of the lighting device 100.
[00119] Les moyens de fixation sont par exemple un système de type boucle et crochet auto agrippant. The fixing means are for example a system of the loop and hook and loop type.
[00120] Les moyens de fixation peuvent également être des moyens permettant une solidarisation amovible du boîtier de protection 110 sur le casque de protection 10. Dans cette variante de réalisation, les moyens de fixation comportent une première partie configurée pour être solidarisée directement sur le casque de protection 10, par exemple au moyen d’une interface adhésive (par exemple un ruban adhésif double face), et une deuxième partie configurée pour être solidarisée sur le boîtier de protection 110 du dispositif d’éclairage 100, par exemple au moyen d’une deuxième interface adhésive (par exemple un ruban adhésif double face), les deux parties étant configurées pour coopérer de manière à réaliser une liaison amovible mécanique et/ou magnétique. [00120] The fixing means can also be means allowing removable attachment of the protective housing 110 on the protective helmet 10. In this variant embodiment, the fixing means comprise a first part configured to be attached directly to the helmet. protection 10, for example by means of an adhesive interface (for example a double-sided adhesive tape), and a second part configured to be secured to the protective housing 110 of the lighting device 100, for example by means of a second adhesive interface (for example a double-sided adhesive tape), the two parts being configured to cooperate so as to produce a removable mechanical and / or magnetic connection.
[00121] Dans l’exemple de réalisation illustré aux figures précédentes, et plus particulièrement à la [fig 4] et à la [fig 2], les moyens de fixation 200 sont formés par l’association d’une interface de montage 210 configurée pour être solidarisée directement sur le support, par exemple un casque de protection 10, et des moyens de blocage 220a, solidaires du boîtier de protection 110, configurés pour assurer une liaison mécanique amovible et des moyens configurés pour assurer une liaison magnétique amovible du dispositif d’éclairage 100 sur l’interface de montage 210. In the embodiment illustrated in the preceding figures, and more particularly in [fig 4] and in [fig 2], the fixing means 200 are formed by the association of a configured mounting interface 210 to be secured directly to the support, for example a protective helmet 10, and locking means 220a, integral with the protective housing 110, configured to provide a removable mechanical connection and means configured to provide a removable magnetic connection of the device d lighting 100 on the mounting interface 210.
[00122] La [fig 5] est une vue en perspective illustrant la partie arrière du dispositif d’éclairage 100 selon l’invention illustré à la [fig 1] pendant le montage du dispositif d’éclairage 100 sur l’interface de montage 210 illustrée à la [fig 4] [00123] La [fig 6] est une vue en perspective illustrant la partie arrière du dispositif d’éclairage 100 selon l’invention illustré à la [fig 1] après le montage du dispositif d’éclairage 100 sur l’interface de montage 210 illustrée à la [fig 4] [00122] [Fig 5] is a perspective view illustrating the rear part of the lighting device 100 according to the invention illustrated in [Fig 1] during the mounting of the lighting device 100 on the mounting interface 210 illustrated in [fig 4] [00123] [Fig 6] is a perspective view illustrating the rear part of the lighting device 100 according to the invention illustrated in [Fig 1] after mounting the lighting device 100 on the mounting interface 210 illustrated in [fig 4]
[00124] L’interface de montage 210 présente au moins une portion intégrant des particules de matériau métallique et/ou de matériau magnétique. [00124] The mounting interface 210 has at least a portion integrating particles of metallic material and / or of magnetic material.
[00125] L’interface de montage 210 est solidarisée sur le casque de protection 10 par l’utilisation d’un élément adhésif 203, par exemple par le dépôt d’une couche adhésive double face, positionné sur une face de l’interface de montage 210 destinée à être en regard avec la surface du casque de protection 10. The mounting interface 210 is secured to the protective helmet 10 by the use of an adhesive element 203, for example by the deposition of a double-sided adhesive layer, positioned on one side of the interface of assembly 210 intended to be opposite the surface of the protective helmet 10.
[00126] L’interface de montage 210 est par exemple une plaque métallique. L’interface de montage 210 est ainsi de faible épaisseur, rendant les moyens de fixation 200 moins encombrant. The mounting interface 210 is for example a metal plate. The mounting interface 210 is thus thin, making the fixing means 200 less bulky.
[00127] Selon une alternative de réalisation, l’interface de montage 210 est réalisée dans un matériau non métallique et/ou non magnétique et présente des portions intégrant des particules de matériau métallique et/ou de matériau magnétique comme des aimants. [00127] According to an alternative embodiment, the mounting interface 210 is made of a non-metallic and / or non-magnetic material and has portions incorporating particles of metallic material and / or of magnetic material such as magnets.
[00128] Les moyens configurés pour assurer une liaison magnétique amovible du dispositif d’éclairage 100 sur l’interface de montage 210 sont formés par une source magnétique 220b logée à l’intérieur du boîtier de protection 110. [00128] The means configured to provide a removable magnetic connection of the lighting device 100 on the mounting interface 210 are formed by a magnetic source 220b housed inside the protective housing 110.
[00129] A titre d’exemple, la source magnétique 220b comporte un ou plusieurs aimants 220b permanents, logée dans le boîtier de protection 110, préférentiellement à proximité de la face arrière 113. [00129] For example, the magnetic source 220b comprises one or more permanent magnets 220b, housed in the protective housing 110, preferably near the rear face 113.
[00130] La source magnétique 220b en combinaison avec l’interface de montage 210 présentant des portions de particules métalliques et/ou magnétiques permet de réaliser une liaison amovible de type magnétique. Ainsi, l’utilisateur peut positionner ou retirer le dispositif d’éclairage 100 de manière aisée et rapide de l’interface de montage 210 et donc du casque de protection 10. [00130] The magnetic source 220b in combination with the mounting interface 210 having portions of metal and / or magnetic particles allows a removable connection of the magnetic type. Thus, the user can position or remove the lighting device 100 easily and quickly from the mounting interface 210 and therefore from the protective helmet 10.
[00131] Toutefois, la source magnétique 220b peut être formée par un unique aimant 220b permanent de manière à réduire les coûts de fabrication ou l’encombrement du dispositif d’éclairage 100 ou encore par une pluralité d’aimants 220b permanents de manière à augmenter la puissance magnétique de la liaison amovible et/ou à répartir les forces magnétiques sur une surface plus importante. However, the magnetic source 220b can be formed by a single permanent magnet 220b so as to reduce the manufacturing costs or the size of the lighting device 100 or even by a plurality of magnets 220b permanent so as to increase the magnetic power of the removable link and / or to distribute the magnetic forces over a larger area.
[00132] Avantageusement, le ou les aimants 220b permanents sont positionnés, au moins en partie, à l’arrière du circuit imprimé 150, c’est-à-dire entre la demi-coque arrière 112 et le circuit imprimé 150. Advantageously, the permanent magnet (s) 220b are positioned, at least in part, at the rear of the printed circuit 150, that is to say between the rear half-shell 112 and the printed circuit 150.
[00133] Avantageusement, le ou les aimants permanents 220b sont positionnés, au moins en partie, à l’arrière des moyens de stockage 140, c’est-à- dire entre la demi-coque arrière 112 et les moyens de stockage 140. Advantageously, the permanent magnet (s) 220b are positioned, at least in part, behind the storage means 140, that is to say between the rear half-shell 112 and the storage means 140.
[00134] Ainsi, le ou les aimants 220b permanents sont positionnés au plus près de la face arrière 113 du boîtier de protection 110 de manière à optimiser la force d’attraction avec les portions métalliques ou magnétiques de l’interface de montage 210. [00134] Thus, the permanent magnet (s) 220b are positioned as close as possible to the rear face 113 of the protective housing 110 so as to optimize the force of attraction with the metal or magnetic portions of the mounting interface 210.
[00135] Le nombre ainsi que les dimensions des aimants 220b permanents sont déterminés de manière à exercer une force d’attraction suffisante pour maintenir en place le dispositif d’éclairage 100 sur un casque de protection 10, quelles que soient les conditions d’utilisation, tout en permettant un découplage aisé pour l’utilisateur. The number as well as the dimensions of the permanent magnets 220b are determined so as to exert a sufficient force of attraction to hold the lighting device 100 in place on a protective helmet 10, regardless of the conditions of use , while allowing easy decoupling for the user.
[00136] Selon une autre variante, la source magnétique est située sur l’interface de montage 210 et le boîtier de protection 110 comprend au moins une portion intégrant des particules de matériau métallique et/ou de matériau magnétique. [00136] According to another variant, the magnetic source is located on the mounting interface 210 and the protective housing 110 comprises at least a portion incorporating particles of metallic material and / or of magnetic material.
[00137] Comme illustré à la [fig 4] illustrant plus particulièrement la face arrière du dispositif d’éclairage 100, la face arrière 113 du boîtier de protection 110 présente une cavité 116, délimitée par une bordure périphérique 117, permettant d’introduire et de loger au moins partiellement l’interface de montage 210. As illustrated in [Fig 4] illustrating more particularly the rear face of the lighting device 100, the rear face 113 of the protective housing 110 has a cavity 116, delimited by a peripheral edge 117, allowing to introduce and to at least partially house the mounting interface 210.
[00138] A titre d’exemple, la cavité 116 peut être ménagée en retrait par rapport à la face arrière 113. Dans ce cas, la profondeur de la cavité 116 est avantageusement identique à l’épaisseur de l’interface de montage 210 munie de l’élément adhésif 203 de sorte que la face arrière 113 du boîtier de protection 110 vienne épouser la surface du casque de protection 10 lorsque le dispositif d’éclairage 100 selon l’invention est en position sur un casque de protection 10. Il est préférable de prévoir un léger jeu entre la face arrière 113 du boîtier de protection 110 et la surface du casque de protection 10 pour être sûr que le contact se fasse bien entre la cavité 116 et l’interface de montage 210. For example, the cavity 116 can be set back relative to the rear face 113. In this case, the depth of the cavity 116 is advantageously identical to the thickness of the mounting interface 210 provided of the adhesive element 203 so that the rear face 113 of the protective housing 110 conforms to the surface of the protective helmet 10 when the lighting device 100 according to the invention is in position on a protective helmet 10. It It is preferable to provide a slight clearance between the rear face 113 of the protective housing 110 and the surface of the protective helmet 10 to be sure that the contact is made between the cavity 116 and the mounting interface 210.
[00139] Selon le mode de réalisation illustré par les figures 1 à 6, la cavité 116 est au niveau de la face arrière 113. Ainsi, la cavité 116 est alors délimitée uniquement par la bordure périphérique 117. La bordure périphérique 117 forme un relief par rapport à la face arrière 113 et présente une hauteur avantageusement identique ou légèrement inférieure à l’épaisseur de l’interface de montage 210 munie de l’élément adhésif 203 afin de laisser un léger jeu entre la bordure périphérique 117 et la surface externe du casque de protection 10 lorsque le dispositif d’éclairage 100 selon l’invention est en position sur un casque de protection 10. According to the embodiment illustrated by Figures 1 to 6, the cavity 116 is at the level of the rear face 113. Thus, the cavity 116 is then delimited only by the peripheral edge 117. The peripheral edge 117 forms a relief relative to the rear face 113 and has a height advantageously identical to or slightly less than the thickness of the mounting interface 210 provided with the adhesive element 203 in order to leave a slight clearance between the peripheral edge 117 and the external surface of the protective helmet 10 when the lighting device 100 according to the invention is in position on a protective helmet 10.
[00140] Ainsi, la cavité 116 est délimitée par une bordure périphérique 117 formant un relief par rapport au fond de la cavité 116, et/ou par rapport à la face arrière 113 du boîtier de protection 110. La bordure périphérique 117 forme avantageusement un moyen d’indexation permettant de faciliter le positionnement du boîtier de protection 110 autour de l’interface de montage 210 et/ou une butée périphérique permettant de bloquer les déplacements du boîtier de protection 110 par rapport à l’interface de montage 210 (tout en autorisant un jeu de montage). [00140] Thus, the cavity 116 is delimited by a peripheral edge 117 forming a relief relative to the bottom of the cavity 116, and / or relative to the rear face 113 of the protective housing 110. The peripheral edge 117 advantageously forms a indexing means making it possible to facilitate the positioning of the protection box 110 around the mounting interface 210 and / or a peripheral stop making it possible to block the movements of the protection box 110 relative to the mounting interface 210 (while allowing an assembly clearance).
[00141] La bordure périphérique 117 est configurée pour bloquer les mouvements du boîtier de protection 110 par rapport à l’interface de montage 210, selon la direction verticale Z et la direction X tangente à la face arrière 113, afin d’éviter que le dispositif d’éclairage 100 se décroche de manière intempestive du casque de protection 10 lors d’un déplacement urbain ou extra-urbain. En effet, la liaison magnétique exerce un effort de maintien selon la direction Y normale à la face arrière 113, mais l’effort d’adhérence du contact entre l’interface de montage 210 et la face arrière 113 du boîtier de protection 110 est insuffisante pour maintenir celui-ci en position selon les directions verticale Z et tangente X. The peripheral edge 117 is configured to block the movements of the protective housing 110 relative to the mounting interface 210, in the vertical direction Z and the direction X tangent to the rear face 113, in order to prevent the lighting device 100 unhooked inadvertently from the protective helmet 10 during urban or extra-urban travel. Indeed, the magnetic link exerts a holding force in the direction Y normal to the rear face 113, but the force of adhesion of the contact between the mounting interface 210 and the rear face 113 of the protective housing 110 is insufficient. to keep it in position in the vertical Z and tangent X directions.
[00142] La cavité 116 présente avantageusement une forme dissymétrique de manière à éviter le montage du dispositif d’éclairage 100 dans une mauvaise position. Notamment, ce détrompage physique limite le risque d’inverser les indicateurs de direction gauche et droite en positionnant le dispositif d’éclairage dans le sens inverse par rapport à l’interface de montage 210. The cavity 116 advantageously has an asymmetrical shape so as to avoid mounting the lighting device 100 in the wrong position. In particular, this physical coding limits the risk of reversing the left and right direction indicators by positioning the lighting device in the opposite direction to the mounting interface 210.
[00143] Les moyens de blocage 220a, solidaires du boîtier de protection 110, configurés par assurer une liaison mécanique amovible, permettent de réaliser un blocage supplémentaire et de garantir le maintien en position du boîtier de protection 110, par effet magnétique, lors d’une utilisation normale du casque de protection 10 en déplacement. Ainsi, les moyens de fixation 200 combinent avantageusement une liaison par effet magnétique ainsi qu’un blocage mécanique bloquant certains mouvements du dispositif d’éclairage 100 lorsque celui-ci est en position autour de l’interface de montage 210 et évitant ainsi le découplage et la perte du dispositif d’éclairage 100. The locking means 220a, integral with the protective housing 110, configured to provide a removable mechanical connection, make it possible to carry out an additional blocking and to guarantee the maintenance in position of the protective housing 110, by magnetic effect, during normal use of the protective helmet 10 on the move. Thus, the fixing means 200 advantageously combine a connection by magnetic effect as well as a mechanical blocking blocking certain movements of the lighting device 100 when the latter is in position around the mounting interface 210 and thus avoiding decoupling and the loss of the lighting device 100.
[00144] Avantageusement, les moyens de blocage 220a permettent de bloquer les rotations du boîtier de protection 110 autour de l’axe tangent X sensiblement parallèle à la surface de contact du boîtier de protection 110 avec le casque de protection 10. Advantageously, the locking means 220a make it possible to block the rotations of the protective housing 110 around the tangent axis X substantially parallel to the contact surface of the protective housing 110 with the protective helmet 10.
[00145] A cet effet, les moyens de blocage 220a comportent au moins un logement 205 ménagé dans une partie supérieure 117a de la bordure périphérique 117 et au moins une dent 204 formant une extension du corps de l’interface de montage 210, avantageusement au niveau de la partie supérieure de l’interface de montage 210. La dent 204 présente une épaisseur adaptée pour s’insérer à l’intérieur de l’espace délimité par le logement 205. For this purpose, the locking means 220a comprise at least one housing 205 formed in an upper part 117a of the peripheral edge 117 and at least one tooth 204 forming an extension of the body of the mounting interface 210, advantageously at level of the upper part of the mounting interface 210. The tooth 204 has a thickness adapted to fit inside the space delimited by the housing 205.
[00146] Comme illustré sur la [fig 5] et la [fig 6], le logement 205 est délimité par une première portion 206 faisant saillie par rapport au fond de la cavité 116 et par une deuxième portion 207 sensiblement perpendiculaire à la première portion 206, et sensiblement parallèle au fond de la cavité 116. Les deux portions 206, 207 forment ainsi un retour de matière en forme de crochet. As illustrated in [Fig 5] and [Fig 6], the housing 205 is delimited by a first portion 206 projecting from the bottom of the cavity 116 and by a second portion 207 substantially perpendicular to the first portion 206, and substantially parallel to the bottom of the cavity 116. The two portions 206, 207 thus form a material return in the form of a hook.
[00147] La dent 204 de l’interface de montage 210 vient s’insérer à l’intérieur du logement 205, c’est-à-dire dans l’espace délimité par les deux portions 206, 207. The tooth 204 of the mounting interface 210 is inserted inside the housing 205, that is to say in the space delimited by the two portions 206, 207.
[00148] La cavité 116 peut comporter des ouvertures 221 dans la zone située en vis-à-vis des deuxièmes portions 207 comme illustré sur la figure 10. Ce mode de réalisation permet de simplifier le procédé de fabrication du boîtier de protection 110 par moulage tout en sécurisant correctement le boîtier de protection 110 sur l’interface de montage 210. Selon ce mode de réalisation, les ouvertures 221 se situent avantageusement à l’extérieur de la zone d’emboîtement des deux demi-coques 111 ,112 afin d’assurer l’étanchéité du boîtier de protection 110. The cavity 116 may include openings 221 in the area located vis-à-vis the second portions 207 as illustrated in FIG. 10. This embodiment makes it possible to simplify the manufacturing process of the housing of protection 110 by molding while correctly securing the protective housing 110 on the mounting interface 210. According to this embodiment, the openings 221 are advantageously located outside the interlocking zone of the two half-shells 111, 112 in order to ensure the tightness of the protective housing 110.
[00149] Pour positionner le dispositif d’éclairage 100 sur l’interface de montage 210, on approche le dispositif d’éclairage 100 de la surface du casque de protection 10 sur laquelle l’interface de montage 210 est positionnée, le dispositif d’éclairage 100 est amené avec une inclinaison par rapport à un plan vertical de manière à présenter la dent 204 à proximité du logement 205. Ensuite par rotation du dispositif d’éclairage 100 autour de l’axe tangent X, on vient rabattre le dispositif d’éclairage 100 autour de l’interface de montage 210, de sorte que celle- ci s’insère dans la cavité 116 et que la dent 204 en partie supérieure s’insère dans l’espace délimité par le logement 205, ayant pour effet de bloquer les déplacements de la dent 204 selon la direction normale Y. To position the lighting device 100 on the mounting interface 210, the lighting device 100 is approached from the surface of the protective helmet 10 on which the mounting interface 210 is positioned, the device for lighting 100 is brought with an inclination relative to a vertical plane so as to present the tooth 204 close to the housing 205. Then, by rotating the lighting device 100 around the tangent axis X, the device is folded down. lighting 100 around the mounting interface 210, so that the latter fits into the cavity 116 and that the tooth 204 in the upper part fits into the space delimited by the housing 205, having the effect of blocking the displacements of tooth 204 in the normal direction Y.
[00150] La rotation autour de l’axe tangent X et le positionnement du dispositif d’éclairage 100 sur le casque de protection 10 sont facilités par l’attraction entre les aimants de la source magnétique 220b et l’interface de montage 210 attirant ainsi le boîtier de protection 110 contre l’interface de montage 210 ainsi que par la bordure périphérique 117 qui permet de s’assurer du bon positionnement de l’interface de montage 210 dans la cavité 116. The rotation around the tangent X axis and the positioning of the lighting device 100 on the protective helmet 10 are facilitated by the attraction between the magnets of the magnetic source 220b and the mounting interface 210 thus attracting the protective housing 110 against the mounting interface 210 as well as by the peripheral edge 117 which makes it possible to ensure the correct positioning of the mounting interface 210 in the cavity 116.
[00151] Une fois en position, le logement 205 est configuré pour former une première butée normale pour limiter, voire bloquer (tout en autorisant un jeu de montage), les déplacements relatifs de la partie supérieure de boîtier de protection 110 selon la direction normale Y sensiblement perpendiculaire à la surface du casque de protection 10, ce qui a pour effet de bloquer les rotations du boîtier de protection 110 autour de l’axe tangent X, sensiblement parallèle à la surface du casque de protection 10. Ainsi, le logement 205 et la dent 204 permettent d’empêcher le décollement du boîtier de protection 110 de l’interface de montage 210 au niveau de la partie supérieure. Le dispositif d’éclairage 100 étant situé à l’avant du logement 205, le logement 205 bloque en rotation selon l’axe tangent X les efforts dus à la gravité et aux accélérations subies en roulage. En effet, une fois le boîtier de protection 110 en position, il est nécessaire de réaliser une cinématique particulière, notamment en pivotant le boîtier de protection 110 vers le haut de manière à décoller en premier la partie inférieure du boîtier de protection 110 du casque de protection 10. Un tel mouvement n’étant pas possible sans l’intervention de l’utilisateur, on s’assure que le dispositif d’éclairage 100 reste en position sur le casque de protection 10 lors d’une utilisation et lors d’un déplacement urbain ou extra-urbain. Once in position, the housing 205 is configured to form a first normal stop to limit, or even block (while allowing an assembly clearance), the relative movements of the upper part of the protective housing 110 in the normal direction Y substantially perpendicular to the surface of the protective helmet 10, which has the effect of blocking the rotations of the protective housing 110 around the tangent axis X, substantially parallel to the surface of the protective helmet 10. Thus, the housing 205 and tooth 204 are used to prevent detachment of protective housing 110 from mounting interface 210 at the top. The lighting device 100 being located at the front of the housing 205, the housing 205 blocks in rotation along the tangent axis X the forces due to gravity and to the accelerations undergone while taxiing. Indeed, once the protective casing 110 is in position, it is necessary to achieve a particular kinematics, in particular by pivoting the protective casing 110 upwards so as to first take off the lower part of the protective casing 110 from the helmet. protection 10. Since such a movement is not possible without the intervention of the user, it is ensured that the lighting device 100 remains in position on the protective helmet 10 during use and during a. urban or extra-urban travel.
[00152] Le logement 205 peut également être configuré pour former une deuxième butée supérieure verticale de manière à limiter, voire à bloquer verticalement (tout en autorisant un jeu de montage), les déplacements du boîtier de protection 110 selon l’axe vertical Z, en association avec la partie inférieure 117d de la bordure périphérique 117 qui forme une butée inférieure verticale. C’est notamment le cas quand le logement 205 est en forme de crochet. The housing 205 can also be configured to form a second vertical upper stop so as to limit, or even block vertically (while allowing an assembly clearance), the movements of the protective housing 110 along the vertical axis Z, in association with the lower part 117d of the peripheral edge 117 which forms a vertical lower stop. This is particularly the case when the housing 205 is hook-shaped.
[00153] Le blocage des déplacements latéraux du dispositif d’éclairage 100 selon l’axe tangent X est réalisé par l’épaisseur de la bordure périphérique 117 et plus particulièrement par les portions latérales 117b, 117c de la bordure périphérique 117 qui forment des butées latérales lorsque le boîtier de protection 110 est en position sur l’interface de montage 210. La bordure périphérique 117 peut ainsi bloquer les déplacements relatifs du boîtier de protection 110 par rapport à l’interface de montage 210 selon des directions normales à la direction Y, ou tangentes à la face arrière 113. The blocking of the lateral movements of the lighting device 100 along the tangent axis X is achieved by the thickness of the peripheral edge 117 and more particularly by the lateral portions 117b, 117c of the peripheral edge 117 which form stops lateral when the protective housing 110 is in position on the mounting interface 210. The peripheral edge 117 can thus block the relative movements of the protective housing 110 with respect to the mounting interface 210 in directions normal to the Y direction , or tangent to the rear face 113.
[00154] Le logement 205 ainsi que la dent 204 de l’interface de montage 210 peuvent s’étendre longitudinalement, selon l’axe tangent X, sur une portion suffisamment importante pour éviter le pivotement du boîtier de protection 110 par rapport à l’interface de montage 210 autour de l’axe normal Y. Ainsi, on évite, ou limite, les possibilités de roulis du dispositif d’éclairage 100. The housing 205 as well as the tooth 204 of the mounting interface 210 can extend longitudinally, along the tangent axis X, over a portion large enough to prevent pivoting of the protective housing 110 relative to the mounting interface 210 around the normal axis Y. Thus, the possibilities of rolling of the lighting device 100 are avoided or limited.
[00155] Avantageusement, la bordure périphérique 117 présente un logement 205 positionné au centre de la partie supérieure 117a de la bordure périphérique 117. [00156] Avantageusement, la bordure périphérique 117 présente deux logements 205 positionnés aux extrémités de la partie supérieure 117a de la bordure périphérique 117 de manière à former deux points d’appui et ainsi bloquer la rotation du boîtier de protection 110 autour de l’axe normal Y. Advantageously, the peripheral edge 117 has a housing 205 positioned in the center of the upper part 117a of the peripheral edge 117. Advantageously, the peripheral edge 117 has two housings 205 positioned at the ends of the upper part 117a of the peripheral edge 117 so as to form two support points and thus block the rotation of the protective housing 110 around the axis normal Y.
[00157] Dans l’exemple de réalisation illustré dans les figures 1 à 6, le boîtier de protection 110 présente trois logements 205 répartis sur la partie supérieure 117a de la bordure périphérique 117 et qui coopèrent avec trois dents 204 ménagées en partie supérieure de l’interface de montage 210. In the embodiment illustrated in Figures 1 to 6, the protective housing 110 has three housings 205 distributed over the upper part 117a of the peripheral edge 117 and which cooperate with three teeth 204 formed in the upper part of the '210 mounting interface.
[00158] Avantageusement, les dents 204 présentent une inclinaison ou un décalage par rapport à la surface de l’interface de montage 210. Cette inclinaison, avantageusement, en direction de la cavité 116, permet de rendre plus visible les erreurs de solidarisation du dispositif d’éclairage 100 sur l’interface de montage 210. En effet, si les dents 204 ne sont pas insérées dans les logements 205, la face arrière 113 est suffisamment distante de l’interface de montage 210 pour que la liaison magnétique ne fasse pas effet, l’utilisateur se rendant ainsi compte du montage du dispositif d’éclairage 100 dans une mauvaise position. Advantageously, the teeth 204 have an inclination or an offset relative to the surface of the mounting interface 210. This inclination, advantageously, in the direction of the cavity 116, makes it possible to make the errors of securing the device more visible. lighting 100 on the mounting interface 210. Indeed, if the teeth 204 are not inserted into the housings 205, the rear face 113 is sufficiently distant from the mounting interface 210 so that the magnetic link does not form. Indeed, the user thus realizing the mounting of the lighting device 100 in the wrong position.
[00159] Les aimants permanents de la source magnétique 220b peuvent être remplacés par un système de clipsage en partie basse de la cavité 116 ou du boîtier de protection 110 afin éviter le basculement vers le haut et le décollement du dispositif d’éclairage 100. Dans ce cas, l’interface de montage 210 n’a pas besoin d’être métallique ou magnétique. The permanent magnets of the magnetic source 220b can be replaced by a clipping system in the lower part of the cavity 116 or of the protective housing 110 in order to prevent upward tilting and detachment of the lighting device 100. In in this case, the mounting interface 210 does not need to be metallic or magnetic.
[00160] Selon une variante de réalisation, le dispositif d’éclairage 100 est directement intégré à la structure extérieure du casque de protection 10, i.e. lors de la fabrication du casque de protection 10. Dans cette variante de réalisation, le boîtier de protection 110 peut être formé par l’association de deux demi-coques comme évoqué précédemment, la demi-coque arrière 112 étant alors solidaire de manière permanente sur le casque de protection 10, la demi-coque avant 111 pouvant être éventuellement amovible par rapport à la demi-coque arrière 112, notamment pour permettre un accès aux unités de stockage si besoin. Dans un autre mode de réalisation, la demi-coque avant 111 est de manière permanente sur le casque de protection 10, la demi-coque arrière 112 étant logée dans l’épaisseur du casque de protection 10. [00160] According to an alternative embodiment, the lighting device 100 is directly integrated into the outer structure of the protective helmet 10, ie during the manufacture of the protective helmet 10. In this alternative embodiment, the protective housing 110 can be formed by the association of two half-shells as mentioned above, the rear half-shell 112 then being permanently attached to the protective helmet 10, the front half-shell 111 possibly being removable from the half-shell rear cover 112, in particular to allow access to the storage units if necessary. In another embodiment, the front half-shell 111 is permanently on the protective helmet 10, the rear half-shell 112 being housed in the thickness of the protective helmet 10.
[00161] Selon une autre variante de réalisation, le dispositif d’éclairage 100 se fixe sur le casque de protection 10 au moyen d’une sangle. [00162] Selon une autre variante de réalisation, le moyen de fixation comporte une pièce qui s’emboîte par coulissement et serrage sur le dispositif d’éclairage 100. [00161] According to another variant embodiment, the lighting device 100 is attached to the protective helmet 10 by means of a strap. [00162] According to another variant embodiment, the fixing means comprises a part which fits by sliding and clamping on the lighting device 100.
[00163] L’invention a également pour objet un casque de protection 10 comportant un dispositif d’éclairage 100 selon l’invention intégré dans la structure du casque de protection 10 ou encore rapporté et solidarisé, via des moyens de fixation, à la surface du casque de protection 10. [00163] The subject of the invention is also a protective helmet 10 comprising a lighting device 100 according to the invention integrated into the structure of the protective helmet 10 or also attached and secured, via fixing means, to the surface protective helmet 10.
[00164] Le casque de protection 10 selon l’invention est un casque permettant à un utilisateur de se protéger la tête lors d’un déplacement urbains ou extra urbains. [00165] Le casque de protection 10 selon l’invention est par exemple un casque pour moto, scooter, vélo, trottinette, monoroue, patin ou planche à roulettes ou encore pour tous moyens de déplacement nécessitant une protection de la tête. [00164] The protective helmet 10 according to the invention is a helmet allowing a user to protect his head when traveling in urban or extra-urban areas. [00165] The protective helmet 10 according to the invention is, for example, a helmet for a motorcycle, scooter, bicycle, scooter, monowheel, skate or skateboard or even for any means of movement requiring protection of the head.
[00166] Le casque de protection 10 selon l’invention peut être un équipement de protection individuel comme un casque dédié à la pratique d’une activité sportive ou un casque de pompier. [00166] The protective helmet 10 according to the invention can be personal protective equipment such as a helmet dedicated to the practice of a sports activity or a firefighter's helmet.
