DESCRIPTION  DESCRIPTION
Titre de l'invention : Module lumineux assurant deux fonctions photométriques présentant des signatures lumineuses distinctes Title of the invention: Light module providing two photometric functions with distinct light signatures
Domaine technique Technical area
La présente invention concerne d'une manière générale le domaine des blocs optiques d'éclairage et de signalisation pour véhicules automobiles. Elle vise en particulier un module lumineux d'un tel bloc optique apte à assurer deux fonctions photométriques d'éclairage et/ou de signalisation différentes.  The present invention relates generally to the field of optical lighting and signaling units for motor vehicles. It relates in particular to a light module of such an optical unit capable of ensuring two different photometric lighting and / or signaling functions.
Technique antérieure Prior art
Les exigences réglementaires en matière de signalisation des véhicules automobiles ont évoluées ces dernières années et imposent désormais la présence à l'avant des véhicule de modules lumineux aptes à assurer la fonction feu diurne, couramment désignée sous l'acronyme anglais DRL (pour « Daytime Running Light »).  Regulatory requirements for signaling motor vehicles have evolved in recent years and now impose the presence at the front of the vehicle of light modules capable of performing the daytime running light function, commonly known by the acronym DRL (for "Daytime Running" Light ”).
Cette fonction feu diurne dont la couleur d'émission lumineuse est blanche, doit être activée automatiquement dès lors que le véhicule se déplace vers l'avant et que les feux de route ou de croisement sont éteints afin d'accroître sa visibilité dans des conditions de lumière du jour.  This daytime running light function, the light emission color of which is white, must be activated automatically as soon as the vehicle is moving forward and the main or dipped beam headlights are switched off in order to increase its visibility in conditions of day light.
De manière courante, les modules lumineux assurant cette fonction feu diurne comprennent une pluralité de diodes électroluminescentes, couramment désignées sous l'acronyme anglais LED (pour « Light Emitting Diodes ») et considérées désormais comme une alternative avantageuse aux ampoules à incandescence en termes d'encombrement, de baisse de consommation d'énergie électrique, d'augmentation de la durée de vie et de liberté de style.  Commonly, the light modules ensuring this daytime running light function comprise a plurality of light-emitting diodes, commonly known under the acronym LED (for “Light Emitting Diodes”) and now considered as an advantageous alternative to incandescent bulbs in terms of space, reduced consumption of electrical energy, increased lifespan and freedom of style.
Ces diodes électroluminescentes sont implantées sur une carte à circuits imprimés désignée couramment sous l'acronyme anglais PCB (pour « Printed Circuit Board ») et intégrant un dispositif de commande. De telles diodes ont toutefois pour inconvénient de présenter u n grand angle d'éclairage, ce qui engendre une large diffusion et beaucoup de pertes dans une application visant à éclairer une zone éloignée. These light-emitting diodes are installed on a printed circuit board commonly known by the acronym PCB (for “Printed Circuit Board”) and incorporating a control device. However, such diodes have the disadvantage of having a large angle of illumination, which generates wide diffusion and many losses in an application intended to illuminate a remote area.
Aussi, il est connu de les associer à un élément optique (par exemple, un réflecteur ou un guide de lumière) apte à modifier le trajet des rayons lumineux issus de ces diodes.  Also, it is known to associate them with an optical element (for example, a reflector or a light guide) capable of modifying the path of the light rays coming from these diodes.
La présence de ces systèmes optiques augmente considérablement le volume des modules lumineux assurant la fonction feu diurne de sorte que leur intégration dans les blocs d'éclairage et de signalisation avant s'avère souvent impossible.  The presence of these optical systems considerably increases the volume of the light modules ensuring the daytime running light function so that their integration into the lighting and front signaling units is often impossible.
Ces modules sont alors intégrés dans des blocs optiques spécifiques implantés dans la calandre et surplombant les blocs optiques d'éclairage et de signalisation avant.  These modules are then integrated into specific optical units located in the grille and overhanging the optical lighting and front signaling units.
Afin de limiter l'encombrement de la face avant du véhicule par une multitudes de blocs optiques, il est connu, d'intégrer dans un même module lumineux les fonctions feu diurne et feu indicateur de direction.  In order to limit the size of the front face of the vehicle by a multitude of optical units, it is known to integrate in a single light module the daytime running light and direction indicator light functions.
Cette dernière fonction, mise en œuvre de manière manuelle via u n organe de commande pour signaler la volonté du conducteur de changer la direction du véhicule, doit également respecter une certaine couleur d'émission lumineuse (en l'occurrence, ambre ou jaune).  This latter function, implemented manually via a control unit to signal the driver's desire to change the direction of the vehicle, must also respect a certain color of light emission (in this case, amber or yellow).
En outre, les exigences réglementaires imposent que les feux diurnes s'éteignent dès qu'un feu indicateur de direction est actionné par l'utilisateur de sorte à le rendre plus visible des autres usagers.  In addition, regulatory requirements require that the daytime running lights go out as soon as a direction indicator light is activated by the user so as to make it more visible to other users.
La demande de brevet européenne EP 2 161 494 divulgue ainsi un module lumineux pour bloc optique de véhicule comportant une première série et une seconde série de diodes électroluminescentes émettant respectivement des rayons lumineux de couleur ambre et de couleur blanche.  European patent application EP 2 161 494 thus discloses a light module for a vehicle optical unit comprising a first series and a second series of light-emitting diodes emitting respectively amber and white light rays.
Les deux séries de diodes sont implantées sur un PCB en regard de la tranche arrière d'un corps transparent sensiblement plat d'un guide optique qui reçoit les rayons lumineux de couleurs différentes provenant desdites diodes et les guide vers sa tranche avant de sortie.  The two sets of diodes are installed on a PCB facing the rear edge of a substantially flat transparent body of an optical guide which receives light rays of different colors from said diodes and guides them to its front edge.
Lors du démarrage du véhicule, la seconde série de diodes à lumière blanche s'allume automatiquement de manière à assurer la fonction feu diurne. Dès lors que le conducteur actionne l'organe de commande traduisant sa volonté de changer la direction du véhicule, cette seconde série de diodes est automatiquement éteinte tandis que la première série de diodes à lumière ambre ou jaune s'allume de sorte à assurer la fonction d'indicateur de direction. When the vehicle starts, the second series of white light diodes automatically lights up to ensure the fire function diurnal. As soon as the driver actuates the control unit, indicating his desire to change the direction of the vehicle, this second series of diodes is automatically extinguished while the first series of amber or yellow light diodes light up so as to ensure the function direction indicator.
Toutefois, avec un tel module lumineux bi-fonction, la signature lumineuse des deux fonctions feu diurne et feu indicateur de direction s'avère parfaitement identique ce qui n'est pas avantageux d'un point de vue du style.  However, with such a dual-function light module, the light signature of the two daytime running light and direction indicator light functions turns out to be perfectly identical, which is not advantageous from a style point of view.

Description détaillée detailed description
La figure 1 représente un module lumineux 1 selon l'invention destiné à être intégré dans un bloc optique avant de signalisation de véhicule automobile pour assurer les fonctions feu diurne et feu indicateur de changement de direction.  FIG. 1 represents a light module 1 according to the invention intended to be integrated in a front optical unit for signaling a motor vehicle to perform the daytime running light and direction change indicator light functions.
Le module lumineux 1 comporte deux plaques support 10, 20 portant chacun une pluralité de sources lumineuses ponctuelles, ainsi qu'un réflecteur 30 en forme de chevron apte à renvoyer les rayons lumineux émis par ces sources lumineuses vers un espace à illuminer. The light module 1 comprises two support plates 10, 20 each carrying a plurality of point light sources, thus that a chevron-shaped reflector 30 capable of returning the light rays emitted by these light sources to a space to be illuminated.
Ce réflecteur 30 comprend un premier tronçon allongé 31 s'étendant selon une direction sensiblement horizontale, un second tronçon allongé 32 s'étendant selon une direction oblique formant u n angle obtus d'environ 120° avec le premier tronçon 31, ainsi qu'un tronçon intermédiaire courbe 33 reliant les deux tronçons 31, 32 par deux de leurs extrémités.  This reflector 30 comprises a first elongated section 31 extending in a substantially horizontal direction, a second elongated section 32 extending in an oblique direction forming an obtuse angle of approximately 120 ° with the first section 31, as well as a section intermediate curve 33 connecting the two sections 31, 32 by two of their ends.
Tel qu'illustré sur les figures 2 et 3, les premier et second tronçons allongés 31, 32 présentent chacun en section un profil semblable de type parabolique.  As illustrated in FIGS. 2 and 3, the first and second elongated sections 31, 32 each have in section a similar profile of the parabolic type.
Le réflecteur 30 est obtenu de préférence par moulage à partir d'un matériau thermoplastique injecté tel que le polyéthylène ou le polypropylène, sa face fonctionnelle étant par la suite recouverte d'un revêtement réfléchissant aluminé.  The reflector 30 is preferably obtained by molding from an injected thermoplastic material such as polyethylene or polypropylene, its functional face subsequently being covered with an aluminized reflective coating.
La première plaque support 10 est formée par une carte à circuits imprimés de type PCB (pour « Printed Circuit Board » en langue anglaise) s'étendant le long du bord interne du premier tronçon allongé horizontal 31 en y étant fixé rigidement.  The first support plate 10 is formed by a printed circuit board of the PCB type (for “Printed Circuit Board” in English) extending along the internal edge of the first horizontal elongated section 31 while being rigidly fixed thereto.
Cette première plaque support 10 porte une série de cinq premières diodes électroluminescentes (LEDS) 40 aptes à émettre des rayons lumineux de couleur blanche.  This first support plate 10 carries a series of five first light-emitting diodes (LEDS) 40 capable of emitting white light rays.
Les diodes 40 sont alignées selon une direction parallèle à l'axe foyer Fi (figure 2) du premier tronçon allongé 31 du réflecteur 30 et régulièrement espacées les unes de autres.  The diodes 40 are aligned in a direction parallel to the focal point Fi (Figure 2) of the first elongated section 31 of the reflector 30 and regularly spaced from each other.
Elles présentent des axes d'émission orientés en direction de ce premier tronçon 31 de sorte que les rayons lumineux Ri issus de ces diodes 40 soient réfléchis par ce dernier vers l'espace à illuminer.  They have emission axes oriented in the direction of this first section 31 so that the light rays Ri coming from these diodes 40 are reflected by the latter towards the space to be illuminated.
La seconde plaque support 20 est également formée par une carte à circuits imprimés de type PCB (pour « Printed Circuit Board » en langue anglaise) s'étendant le long du bord externe du second tronçon allongé oblique 32 en y étant fixé rigidement. Cette seconde plaque support 10 porte une série de cinq secondes diodes électroluminescentes (LEDS) 50 aptes à émettre alternativement des rayons lumineux de couleur blanche et de couleur ambre. The second support plate 20 is also formed by a printed circuit board of the PCB type (for “Printed Circuit Board” in English) extending along the external edge of the second oblique elongated section 32 while being rigidly fixed thereto. This second support plate 10 carries a series of five second light-emitting diodes (LEDS) 50 capable of alternately emitting light rays of white color and amber color.
Les diodes 50 sont alignées selon une direction parallèle à l'axe foyer F2 (figure 3) du second tronçon allongé 32 du réflecteur 30 et régulièrement espacées les unes de autres. The diodes 50 are aligned in a direction parallel to the focal point F 2 (Figure 3) of the second elongated section 32 of the reflector 30 and regularly spaced from each other.
Elles présentent des axes d'émission orientés en direction de ce second tronçon 32 de sorte que les rayons lumineux R2 issus de ces diodes 50 soient réfléchis par ce dernier vers l'espace à illuminer. They have emission axes oriented towards this second section 32 so that the light rays R 2 coming from these diodes 50 are reflected by the latter towards the space to be illuminated.
Tel qu'illustré par la figure 1, la première plaque support 10 comprend une extension 11 se prolongeant, au-delà du premier tronçon allongé horizontal 31 du réflecteur 30, jusqu'à la seconde plaque support 20, de sorte à constituer un écran limitant les réflexions parasites de rayons lumineux issus de la seconde série de diodes 50 sur le tronçon intermédiaire courbe 33 et le premier tronçon allongé horizontal 31.  As illustrated in FIG. 1, the first support plate 10 comprises an extension 11 extending beyond the first horizontal elongated section 31 of the reflector 30, up to the second support plate 20, so as to constitute a limiting screen the stray reflections of light rays coming from the second series of diodes 50 on the curved intermediate section 33 and the first horizontal elongated section 31.
L'extrémité libre de cette extension 11 est avantageusement profilée de sorte à être jointive avec la seconde plaque support 20, de sorte qu'aucun rayon lumineux provenant des diodes 50 ne puisse passer entre les deux plaques support 10, 20.  The free end of this extension 11 is advantageously profiled so as to be contiguous with the second support plate 20, so that no light ray coming from the diodes 50 can pass between the two support plates 10, 20.
Cette extension 11 de la plaque support 10 porte une diode électroluminescente 60, alignée avec les premières diodes 40, et apte à émettre des rayons lumineux de couleur identique (i.e. blanche) à celle des rayons émis par ces premières diodes 40.  This extension 11 of the support plate 10 carries a light-emitting diode 60, aligned with the first diodes 40, and capable of emitting light rays of identical color (i.e. white) to that of the rays emitted by these first diodes 40.
La diode 60 présente un axe d'émission orienté en direction du tronçon intermédiaire courbe 33 de sorte que les rayons lumineux issus de cette diode soient réfléchis par ce dernier vers l'espace à illuminer.  The diode 60 has an emission axis oriented in the direction of the curved intermediate section 33 so that the light rays coming from this diode are reflected by the latter towards the space to be illuminated.
Comme on peut le voir su r la figu re 1, la seconde plaq ue su pport 20 comprend également une extension 21 se prolongeant, au-delà du second tronçon allongé oblique 32 du réflecteur 30, en regard du tronçon intermédiaire courbe 33.  As can be seen in FIG. 1, the second plate on port 20 also includes an extension 21 extending beyond the second oblique elongated section 32 of the reflector 30, facing the curved intermediate section 33.
Cette extension 21 de la plaque support 20 porte une diode électroluminescente 70, alignée avec les secondes diodes 50, et apte à émettre des rayons lumineux de couleur identique (i.e. blanche) à celle des rayons émis par les premières diodes 40. La diode 70 présente un axe d'émission orienté en direction du tronçon intermédiaire courbe 33 de sorte que les rayons lumineux issus de cette diode soient réfléchis par ce dernier vers l'espace à illuminer. This extension 21 of the support plate 20 carries a light-emitting diode 70, aligned with the second diodes 50, and capable of emitting light rays of identical color (ie white) to that of the rays emitted by the first diodes 40. The diode 70 has an emission axis oriented in the direction of the curved intermediate section 33 so that the light rays coming from this diode are reflected by the latter towards the space to be illuminated.
Les deux plaques support 10, 20 sont avantageusement de couleur blanche de manière à rediriger vers le réflecteur 30 la très grande majorité des rayons lumineux réfléchis vers ces dernières par ce réflecteur 30, et à éviter ainsi la vision de zones d'ombre par u n observateur externe regardant le module lumineux 1.  The two support plates 10, 20 are advantageously white in color so as to redirect towards the reflector 30 the vast majority of the light rays reflected towards the latter by this reflector 30, and thus avoid the vision of shadow areas by an observer. external looking at the light module 1.
Ces plaques support 10, 20 sont également reliées à un dispositif de commande non représenté et apte à gérer l'allumage et l'extinction des diodes lumineuses 40, 50, 60 et 70.  These support plates 10, 20 are also connected to a control device not shown and capable of managing the switching on and off of the light diodes 40, 50, 60 and 70.
Lors du démarrage du véhicule, les diodes 40, 50 60 et 70 s'allument automatiquement en émettant des rayons lumineux blancs vers les trois tronçons 31, 32, 33 du réflecteur 30, de manière à assurer la fonction feu diurne.  When the vehicle starts, the diodes 40, 50 60 and 70 light up automatically by emitting white light rays towards the three sections 31, 32, 33 of the reflector 30, so as to ensure the daytime running light function.
Cette fonction présente ainsi une signature lumineuse continue en forme de chevron correspondant à la forme du réflecteur 30.  This function thus has a continuous chevron-shaped light signature corresponding to the shape of the reflector 30.
La présence de deux diodes 60 et 70 dont les axes d'émission sont orientés vers ce tronçon intermédiaire 33 permet d'assurer une meilleure homogénéité de l'intensité lumineuse sur l'ensemble du réflecteur 30 (ce tronçon intermédiaire 33 serait en effet moins lumineux que les deux autres tronçons allongés 31, 32 si l'une de ces deux diodes était absente).  The presence of two diodes 60 and 70 whose emission axes are oriented towards this intermediate section 33 ensures better homogeneity of the light intensity over the whole of the reflector 30 (this intermediate section 33 would indeed be less bright than the other two elongated sections 31, 32 if one of these two diodes was absent).
Dès lors que le conducteur actionne l'organe de commande traduisant sa volonté de changer la direction du véhicule, les diodes 40, 60 et 70 sont automatiquement éteintes tandis que la couleur des rayons lumineux émis par les diodes 50 en direction du seul second tronçon allongé oblique 32 passe du blanc à l'ambre, de sorte à assurer la fonction feu indicateur de changement direction.  As soon as the driver actuates the control unit, reflecting his desire to change the direction of the vehicle, the diodes 40, 60 and 70 are automatically extinguished while the color of the light rays emitted by the diodes 50 towards the only second elongated section oblique 32 changes from white to amber, so as to ensure the direction change indicator light function.
Cette fonction présente ainsi une signature lumineuse continue de forme allongée oblique correspondant à celle du second tronçon 32 du réflecteur 30.  This function thus has a continuous light signature of oblique elongated shape corresponding to that of the second section 32 of the reflector 30.
La présence de l'écran formé par l'extension 11 de la première plaque support 10 permet de définir précisément l'extrémité inférieure de cette signature lumineuse (le tronçon intermédiaire 33 et le premier tronçon 31 du réflecteur 30 ne recevant alors aucun rayon lumineux ou quasiment) de sorte à obtenir un meilleur rendu visuel et à respecter la réglementation concernant la hauteur minimale de la fonction feu indicateur de changement direction (celle-ci devant se situer à au moins 350 mm du sol). The presence of the screen formed by the extension 11 of the first support plate 10 makes it possible to precisely define the lower end of this light signature (the intermediate section 33 and the first section 31 of the reflector 30 then receiving no light beam or almost) so as to obtain a better visual rendering and to comply with the regulations concerning the minimum height of the direction change indicator light function (this must be at least 350 mm from the ground).
Selon des variantes de réalisation non représentées, les diodes électroluminescentes sont remplacées par d'autres sources lumineuses ponctuelles telles que des diodes laser.  According to alternative embodiments not shown, the light-emitting diodes are replaced by other point light sources such as laser diodes.
Selon d'autres variantes de réalisation non représentées, les diodes de la seconde série sont aptes à émettre seulement des rayons lumineux de couleur ambre.  According to other variant embodiments not shown, the diodes of the second series are capable of emitting only light rays of amber color.
Selon encore d'autres variantes de réalisation, le nombre et/ou les couleurs d'émission des diodes formant la première et/ou la seconde séries de diodes sont différent (chacune de ces séries comprenant par exemple entre 4 et 10 diodes alignées).  According to yet other alternative embodiments, the number and / or the emission colors of the diodes forming the first and / or the second series of diodes are different (each of these series comprising for example between 4 and 10 aligned diodes).
Selon encore d'autres variantes de réalisation, l'angle entre les deux tronçons allongés du réflecteur est également différent et par exemple compris entre 90 et 130°.  According to yet other alternative embodiments, the angle between the two elongated sections of the reflector is also different and for example between 90 and 130 °.
D'une manière générale, on rappelle que la présente invention ne se limite pas aux formes de réalisation décrites et représentées, mais englobe toute variante d'exécution à la portée de l'homme du métier.  In general, it is recalled that the present invention is not limited to the embodiments described and shown, but encompasses any variant within the reach of the skilled person.
