Description

La présente invention a trait d'une façon générale aux feux de signalisation pour véhicules automobiles.The present invention relates generally to signaling lights for motor vehicles.

Elle concerne plus particulièrement un feu de signalisation comprenant une source lumineuse telle qu'une lampe à filament, un récupérateur de flux, un voyant de fermeture ainsi qu'un écran intermédiaire placé entre le récupérateur de flux et le voyant.It relates more particularly to a signaling comprising a light source such as a filament lamp, flow recuperator, indicator light closure as well as an intermediate screen placed between the flow recuperator and indicator.

Lorsque l'on souhaite donner à un tel feu de signalisation éteint une teinte rouge, alors que la fonction de signalisation doit être d'une autre couleur (par exemple ambre pour un feu clignotant indicateur de direction, ou blanche pour un feu de recul ou un feu de position avant), il est classique de teinter le voyant en rose et de prévoir sur la face externe de l'écran intermédiaire un ensemble de régions rouges opaques ou semi-opaques, par exemple en forme de bandes parallèles de préférence horizontales.When one wishes to give such a fire signaling extinguishes a red tint, while the function sign must be of another color (for example amber for a direction indicator flashing light, or white for a reversing light or a front position light), it is usual to tint the light in pink and plan on the external face of the intermediate screen a set of opaque or semi-opaque red regions, for example shaped preferably horizontal parallel bands.

Ce feu connu comporte également sur la face interne du voyant des aménagements optiques de diffusion de la lumière, telles que des billes sphériques ou des surfaces toriques de préférence convexes.This known fire also comprises on the internal face of the seeing optical arrangements for light scattering, such as spherical balls or toric surfaces of preferably convex.

Afin notamment de donner au feu lorsqu'il est éteint un aspect aussi homogène que possible, il est classique, comme le montrent les figures 1 et 2 des dessins annexés qui illustrent un écran intermédiaire connu E et le voyant extérieur associé V, de positionner les bandes opaques B de telle sorte qu'elles présentent le même pas que les rangées de tores du voyant, de préférence en chevauchant symétriquement les plans horizontaux PT qui s'étendent aux transitions entre deux rangées adjacentes de tores Ti et Ti+1.In particular to give fire when it is out a aspect as homogeneous as possible, it is classic, like shown in Figures 1 and 2 of the accompanying drawings which illustrate a known intermediate screen E and the indicator associated exterior V, to position the opaque bands B of so that they have the same pitch as the rows toroid toroid, preferably overlapping symmetrically the horizontal planes PT which extend to the transitions between two adjacent rows of Ti cores and Ti + 1.

Cette solution est cependant désavantageuse en ce qu'elle provoque dans le relevé photométrique du feu des zones sombres tout à fait indésirables car elles empêchent au feu d'être conforme aux règlements en certains points de mesure de la grille photométrique. This solution is however disadvantageous in that that it causes in the photometric reading of the fire completely undesirable dark areas because they prevent fire to comply with regulations at certain points of photometric grid measurement.

Plus précisément, si l'on se réfère à la figure 3 des dessins, on constate qu'il existe dans l'allure du faisceau obtenu, définie par un ensemble de courbes isocandéla, deux bandes horizontales B1 et B2 dans lesquelles la lumière est absente, ou tout au moins largement insuffisante.More specifically, if we refer to Figure 3 of drawings, we see that it exists in the shape of the beam obtained, defined by a set of isocandela curves, two horizontal bands B1 and B2 in which the light is absent, or at least largely insufficient.

Ces bandes noires sont en fait les images, formés par les tores, des bandes opaques B présentes sur l'écran intermédiaire.These black bands are in fact the images, formed by the toroids, opaque bands B present on the screen intermediate.

Un tel phénomène se rencontrerait également si les billes ou tores du voyant étaient remplacés par des stries cylindriques horizontales.Such a phenomenon would also be encountered if the balls or indicator toroids were replaced by streaks horizontal cylindrical.

Ce problème peut également se rencontrer lorsque des bandes opaques chevauchent des plans de transition horizontaux entre des aménagements optiques prévus non pas sur la face interne du voyant, mais ailleurs et notamment sur la face interne de l'écran intermédiaire.This problem can also be encountered when opaque bands overlap horizontal transition planes between optical arrangements not on the face internal light, but elsewhere and especially on the face internal of the intermediate screen.

On connaít d'autre part, en particulier par FR-A-2 427 549 et EP-A-0 180 145, un feu de signalisation conforme au préambule de la revendication 1, qui de par la différence des pas entre les éléments optiques et les bandes opaques, pourrait ne pas donner lieu de façon aussi marquée au phénomène des bandes sombres expliqué plus haut.We know on the other hand, in particular by FR-A-2 427 549 and EP-A-0 180 145, a signaling light conforming to preamble of claim 1, which by the difference of not between the optical elements and the opaque bands, may not give rise to as markedly dark stripe phenomenon explained above.

La présente invention vise à proposer un feu de signalisation du type précité qui, tout en conservant un aspect similaire, restant homogène, lorsqu'il est éteint, engendre un faisceau de signalisation n'ayant plus le défaut précité, et qui en outre soit optimisé sur le plan de l'homogénéité.The present invention aims to provide a fire signaling of the aforementioned type which, while retaining a similar appearance, remaining homogeneous, when it is off, generates a signaling beam no longer having the fault mentioned above, and which is further optimized in terms of uniformity.

Ainsi la présente invention propose un feu de signalisation tel que défini dans la revendication 1. Thus the present invention provides a fire signaling as defined in claim 1.

Des aspects préférés, mais non limitatifs, du dispositif selon l'invention sont définis dans les revendications dépendantes.Preferred, but not limiting, aspects of the device according to the invention are defined in the claims dependent.

D'autres aspects, buts et avantages de la présente invention apparaítront mieux à la lecture de la description détaillée suivante d'une forme de réalisation préférée de celle-ci, donnée à titre d'exemple et faite en référence aux dessins annexés, sur lesquels :

  • la figure 1 est une vue de face d'un voyant et d'un écran intermédiaire, vu par transparence, d'un feu de signalisation de l'art antérieur,
  • la figure 2 est une vue en coupe verticale du voyant et de l'écran intermédiaire de la figure 1,

  • la figure 6 est une vue en coupe verticale d'un feu de signalisation incorporant un voyant et un écran intermédiaire selon l'invention.
    • Other aspects, objects and advantages of the present invention will appear better on reading the following detailed description of a preferred embodiment thereof, given by way of example and made with reference to the accompanying drawings, in which :
  • FIG. 1 is a front view of an indicator and an intermediate screen, seen by transparency, of a signaling light of the prior art,
  • FIG. 2 is a view in vertical section of the indicator and of the intermediate screen of FIG. 1,
  • FIG. 3 illustrates by a set of isocandela curves the photometric appearance of the beam generated with the indicator and the intermediate screen of FIGS. 1 and 2,
  • FIG. 4 is a front view of an indicator and an intermediate screen, seen by transparency according to the invention,

  • Figure 6 is a vertical sectional view of a signaling light incorporating an indicator and an intermediate screen according to the invention.

    • En référence tout d'abord à la figure 4, un voyant de fermeture 40 d'un feu selon l'invention comporte sur sa face intérieure un réseau d'éléments optiques, en l'espèce des tores convexes 41, disposés selon une pluralité de rangées horizontales adjacentes R1, ..., Rn, de façon connue en soi.Referring first to FIG. 4, an indicator light closure 40 of a light according to the invention has on its face interior a network of optical elements, in this case convex toroids 41, arranged in a plurality of rows adjacent horizontal R1, ..., Rn, in a manner known per se.

    On rappellera ici que des tores sont des surfaces qui présentent, respectivement en section horizontale et en section verticale, des profils circulaires de rayons différents, ceci afin d'assurer un étalement de la lumière différent en direction horizontale et en direction verticale.It will be recalled here that tori are surfaces which have, respectively in horizontal section and in vertical section, circular radius profiles different, this in order to ensure a spread of the light different in horizontal direction and in direction vertical.

    Toutes les rangées de tores présentent la même hauteur, avec un pas vertical P3 en l'espèce choisi égal à 3 mm.All the rows of toroids have the same height, with a vertical pitch P3 in this case chosen equal to 3 mm.

    L'écran intermédiaire 30 présente sur sa face externe une pluralité de bandes opaques ou semi-opaques horizontales et parallèles 31, réalisées par exemple par sérigraphie. The intermediate screen 30 has on its external face a plurality of horizontal opaque or semi-opaque bands and parallel 31, produced for example by screen printing.

    Ces bandes 31 délimitent deux à deux des bandes transparentes 32 de passage de la lumière émise à partir de l'intérieur du feu.These bands 31 delimit two by two of the bands transparencies 32 for the passage of light emitted from inside the fire.

    Ces bandes présentent un pas régulier et de préférence une largeur constante.These bands have a regular pitch and preferably a constant width.

    Dans le présent exemple, on positionne les bandes opaques 31 de telle sorte qu'une première bande 31c située à une hauteur intermédiaire sur le voyant chevauche symétriquement un plan de transition intermédiaire PTc entre deux rangées de tores adjacentes Ri, Ri+1, et de telle sorte que deux bandes opaques 31h et 31b situées respectivement le long du bord supérieur et du bord inférieur de l'écran 30 ou d'une zone déterminée de celui-ci soient non pas situées à cheval sur deux rangées de tores comme pour la bande 31c, mais soient situées, en direction verticale sensiblement au centre d'une rangée de tores correspondante, respectivement R1 et Rn.In this example, we position the bands opaque 31 so that a first strip 31c located at an intermediate height on the sight glass overlaps symmetrically an intermediate transition plane PTc between two rows of adjacent tori Ri, Ri + 1, and so that two opaque bands 31h and 31b located respectively on along the upper edge and the lower edge of the screen 30 or of a specific area thereof are not located horse on two rows of toroids as for band 31c, but are located, in a vertical direction substantially at center of a corresponding row of toroids, respectively R1 and Rn.

    Les bandes 31 sont réparties avec un pas régulier, d'une part entre la bande intermédiaire 31c et la bande supérieure 31h, et d'autre part entre la bande intermédiaire 31c et la bande inférieure 31b.The bands 31 are distributed with a regular pitch, on the one hand between the intermediate strip 31c and the strip greater than 31h, and on the other hand between the intermediate band 31c and the lower strip 31b.

    Du fait que les deux bandes extrêmes occupent à chaque fois des positions relatives différentes par rapport aux rangées de tores adjacentes, il en résulte un décalage progressif des bandes par rapport aux rangées de tores, à partir de la position chevauchante de la bande 31c jusqu'aux positions des bandes extrêmes 31h, 31b.Because the two extreme bands occupy each times different relative positions with respect to rows of adjacent toroids, this results in an offset progressive bands with respect to the rows of toroids, from the overlapping position of the strip 31c to positions of the end bands 31h, 31b.

    De par ce décalage progressif, chaque couple rangée de tores/bande se comporte optiquement de façon différente et il en résulte, comme le montre la figure 5, un relevé photométrique qui est tout à fait homogène, et en particulier dépourvu de toute zone sombre ou moins éclairée susceptible de rendre le faisceau non conforme aux règlements. Dans le même temps, l'effet rendu par les bandes lorsque le feu est éteint est sensiblement identique à celui obtenu dans le cas de la figure 1, et en particulier une bonne homogénéité de son aspect est conservée.Because of this progressive shift, each pair of rows of toroid / strip behaves optically differently and as a result, as shown in FIG. 5, a reading photometric which is completely homogeneous, and in private person devoid of any dark or less lit area likely to make the beam non-compliant with regulations. At the same time, the effect rendered by the bands when the fire is out is substantially identical to that obtained in the case of FIG. 1, and in particular a good homogeneity of its appearance is preserved.

    Dans le cas d'espèce, l'écran intermédiaire et le voyant sont communs à deux fonctions lumineuses différentes, le plan de transition PTc précité séparant les deux plages éclairantes.In this case, the intermediate screen and the indicator lights are common to two different light functions, the aforementioned PTc transition plan separating the two ranges illuminating.

    Du fait que le nombre de rangées de tores dans les deux plages éclairantes est différent, il en résulte que le pas entre les bandes est également différent d'une plage à l'autre.Because the number of rows of toroids in the two illuminating areas is different, it follows that the pitch between bands is also different from range to the other.

    Avec l'exemple concret tel qu'illustré sur la figure 4, on aboutit pour les bandes situées au-dessus de la bande intermédiaire 31c, à un pas P1 de 3,18 mm et, pour les bandes situées au-dessous de la bande intermédiaire 31c, à un pas P2 de 3,23 mm.With the concrete example as illustrated in figure 4, we end up for the bands located above the band intermediate 31c, at a pitch P1 of 3.18 mm and, for bands located below the intermediate band 31c, at a pitch of 3.23 mm P2.

    Ainsi le rapport entre le pas P3 des rangées de tores et le pas P1 ou P2 des bandes est dans un cas de 1,06, et dans l'autre de 1,076.Thus the ratio between the step P3 of the rows of toroids and the pitch P1 or P2 of the bands is in a case of 1.06, and in the other of 1.076.

    Selon la configuration, la taille et le nombre des différents éléments, on aura recours dans la pratique à un rapport entre pas compris le plus souvent entre 1,02 et 1,15.Depending on the configuration, the size and number of different elements, we will use in practice a most often not between 1.02 and 1.15.

    Alternativement, on peut bien entendu augmenter le nombre de bandes opaques 31 entre une bande chevauchant deux rangées de tores et une bande centrée sur une rangée de tores, pour obtenir dans ce cas un rapport entre pas inférieur à 1.Alternatively, it is of course possible to increase the number of opaque bands 31 between a band overlapping two rows of toroids and a strip centered on a row of toroids, to obtain in this case a ratio between steps less than 1.

    On a illustré sur la figure 6 une forme de réalisation concrète d'un ensemble de feux de signalisation équipé d'un écran intermédiaire tel que décrit ci-dessus, à savoir un feu clignotant indicateur de direction et un feu de recul.An embodiment has been illustrated in FIG. 6 of a set of traffic lights fitted with a intermediate screen as described above, namely a direction indicator light and reversing light.

    Il comprend un socle 10 définissant deux cavités 11a, 11b dont les fonds constituent des miroirs récupérateurs de flux 12a, 12b, par exemple du genre parabolique. Dans chaque cavité pénètre à partir du fond une lampe, respectivement 20a, 20b.It includes a base 10 defining two cavities 11a, 11b, the bottoms of which constitute recovery mirrors flow 12a, 12b, for example of the parabolic kind. In each cavity penetrates from the bottom a lamp, respectively 20a, 20b.

    L'écran intermédiaire 30 recouvre les deux cavités, le plan de transition PTc chevauché symétriquement par la bande opaque 31c constituant la frontière entre les plages éclairantes des deux feux. Un voyant 40 comportant les éléments optiques 41 s'étend le long et à l'extérieur de l'écran 30. Ce voyant est teinté en rose sur toute son étendue.The intermediate screen 30 covers the two cavities, the PTc transition plane overlapped symmetrically by the strip opaque 31c constituting the border between the beaches two lights. A light 40 comprising the optics 41 extends along and outside of screen 30. This indicator is tinted pink all over extended.

    Le feu supérieur est un feu clignotant indicateur de direction et, pour émettre la couleur ambre requise, la partie de l'écran 30 située au dessus du plan de transition PTc est teintée en vert.The upper light is a flashing light indicating direction and, to emit the required amber color, the part of the screen 30 located above the transition plane PTc is tinted green.

    Le feu inférieur est un feu de recul et, pour émettre la couleur blanche requise, la partie de l'écran 30 située au-dessous du plan de transition PTc est teintée en bleu. A cet effet, l'écran 30 est de préférence réalisé par moulage en deux étapes.The lower light is a reversing light and, to emit the required white color, the part of the screen 30 located below the transition plane PTc is tinted blue. AT for this purpose, the screen 30 is preferably produced by molding in two steps.

    Lorsque cet ensemble de deux feux est éteint, la combinaison de la teinte rose du voyant 40 et de la couleur rouge des bandes opaques 31 lui donne un aspect rouge homogène, qui se marie bien avec d'autres feux adjacents de teinte rouge (feu de position, feu stop, feu de brouillard arrière, ...).When this set of two lights is turned off, the combination of the pink shade of the indicator light 40 and the color red opaque stripes 31 gives it a red appearance homogeneous, which goes well with other adjacent lights of red tint (position light, brake light, fog light back, ...).

    Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite et représentée, mais l'homme du métier saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is by no means limited to the embodiment described and shown, but the person skilled in the art will be able to bring there any variant or modification according to his spirit.

    En particulier, la présente invention s'applique également à toute situation où des bandes opaques où semi-opaques coexistent avec des rangées parallèles d'éléments optiques prévues ailleurs que sur le voyant.In particular, the present invention applies also in any situation where opaque or semi-opaque bands coexist with parallel rows of elements optics provided elsewhere than on the indicator.
