Abstract

The indicator light includes a sealed box, housing the light source. This source is mounted on the inside of the front cover glass, and produces light, all of which passes via a rear reflector before emerging through the outer regions of the cover glass. The lamp is not seen directly from outside, producing a more uniform distribution of light. The indicator light unit for a vehicle includes a box (6) mounted in a recess in the vehicle bodywork (9). The box comprises a reflective surface (12) which forms part of the closed box together with a transparent front glass (7). The light emitting source (1) is mounted on the inside surface of the front glass, in a support (15). Light emerging from the source is directed towards the reflective surface (6), and then reflected out through the front glass. A back-reflecting region on the front glass ensures that the portion of glass immediately surrounding the light source serves as an external reflector.

FEU DE SIGNALISATION DE VEHICULE AUTOMOBILE POUR DIFFUSION DE FAISCEAUX LUMINEUX INDIRECTS
L'invention se rapporte à un dispositif d'éclairage qui permet la signalisation des véhicules automobiles. MOTOR VEHICLE SIGNALING LIGHT FOR INDIRECT LIGHT BEAMS BROADCAST
The invention relates to a lighting device which allows the signaling of motor vehicles.

L'invention concerne plus particulièrement un feu de signalisation pour véhicule automobile comportant un boîtier de feu de signalisation fixé sur la carrosserie du véhicule, le boîtier comprend une surface réfléchissante et supporte la vitre extérieure transparente.  The invention relates more particularly to a signaling light for a motor vehicle comprising a signaling light housing fixed to the vehicle body, the housing comprises a reflective surface and supports the transparent outer window.

Les documents EP0633163 et FR2733299 enseignent les principaux avantages que l'on trouve dans l'utilisation d'une source lumineuse autre que celle émanant des lampes à incandescence pour la signalisation des véhicules automobiles. Ainsi, l'utilisation d'un dispositif d'éclairage associant une pluralité de sources lumineuses individuelles à diodes électroluminescentes ou un barreau optique alimenté par un flux lumineux transitant via une fibre optique, des aménagements optiques et un voyant transparent de feu de signalisation, est déjà connue dans la technique.  The documents EP0633163 and FR2733299 teach the main advantages which are found in the use of a light source other than that emanating from incandescent lamps for the signaling of motor vehicles. Thus, the use of a lighting device associating a plurality of individual light sources with light-emitting diodes or an optical bar powered by a light flux passing through an optical fiber, optical arrangements and a transparent signal light indicator, is already known in the art.

Cependant, ces dispositifs de signalisation ne donnent pas toute satisfaction dans ce sens où ces associations de composants génèrent des rayons lumineux directs. La source émettrice de ces rayons lumineux est visible de l'extérieur du véhicule. De plus, lorsque le dispositif de signalisation comprend l'association d'une source de rayons lumineux directs et des lentilles de Fresnel, la visualisation de la source émettrice est encore plus accentuée. Ce manque d'homogénéité dans la répartition surfacique du flux lumineux est synonyme d'un manque de confort visuel et de caractère esthétique.  However, these signaling devices are not entirely satisfactory in the sense that these combinations of components generate direct light rays. The source emitting these light rays is visible from outside the vehicle. In addition, when the signaling device comprises the association of a source of direct light rays and Fresnel lenses, the display of the emitting source is even more accentuated. This lack of homogeneity in the surface distribution of the light flux is synonymous with a lack of visual comfort and aesthetic character.

Le document FR2753521 présente une solution répondant aux exigences liées au caractère esthétique afin d'homogénéiser l'aspect du feu lorsqu'il est éteint. Ce type de  The document FR2753521 presents a solution which meets the requirements linked to the aesthetic nature in order to standardize the appearance of the fire when it is extinguished. This kind of

feu de signalisation intègre un cache rétroréfléchissant situé entre la lampe et la vitre. La source émettrice de faisceaux lumineux est quant à elle située sur un récupérateur de flux brillant et orientée en direction de la vitre. Cette solution est avantageuse lorsque le feu est éteint mais n'empêche en aucun cas la visualisation de la source émettrice de faisceaux lumineux lorsqu'elle est sollicitée.  traffic light incorporates a retroreflective cover located between the lamp and the glass. The light beam emitting source is located on a bright flux recuperator and oriented towards the glass. This solution is advantageous when the fire is extinguished but in no way prevents the visualization of the source emitting light beams when it is requested.

Un but de la présente invention est de proposer un dispositif d'éclairage par feu de signalisation pour véhicule automobile, palliant tout ou partie des inconvénients de l'art antérieur relevés ci-dessus.  An object of the present invention is to provide a lighting device by signaling light for a motor vehicle, overcoming all or part of the drawbacks of the prior art noted above.

A cette fin, l'invention a pour objet un feu de signalisation pour véhicule automobile comportant un boîtier, monté sur la carrosserie du véhicule, comprenant une surface réfléchissante fermée par une vitre extérieure transparente et une source lumineuse. Selon l'invention ladite source lumineuse est disposée sur la face interne de la vitre et émet des rayons lumineux orientés vers la surface réfléchissante du boîtier.  To this end, the invention relates to a signaling light for a motor vehicle comprising a housing, mounted on the body of the vehicle, comprising a reflective surface closed by a transparent outer window and a light source. According to the invention, said light source is arranged on the internal face of the glass and emits light rays directed towards the reflecting surface of the housing.

Selon d'autres caractéristiques et/ou variantes de l'invention : 'La vitre comporte un élément rétroréfléchissant adjacent à la source lumineuse, de dimension telles qu'il masque la vue extérieure de ladite source 'La source lumineuse est agencée dans une canelure longitudinale a Le fond de la canelure est formé par l'élément rétroréfléchissant
La source lumineuse est constituée d'une succession de diodes électroluminescentes agencées dans un support de maintien According to other characteristics and / or variants of the invention: 'The glass comprises a retroreflective element adjacent to the light source, of a size such that it masks the external view of said source' The light source is arranged in a longitudinal groove a The bottom of the groove is formed by the retroreflective element
The light source consists of a succession of light-emitting diodes arranged in a holding support

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

La source lumineuse est constituée d'un conduit de lumière du type à fibre optique associé à une source (13) unique génératrice de faisceaux lumineux. The light source consists of a light pipe of the optical fiber type associated with a single source (13) generating light beams.

D'autres particularités et avantages apparaîtront à la lecture de la description ci-après faite en référence aux figures dans lesquelles : - la figure 1 représente une vue en coupe transversale d'un feu de signalisation selon l'invention, - la figure 2 représente une vue en coupe transversale détaillée d'un support de fixation des diodes électroluminescentes, - la figure 3 représente une vue en coupe suivant A du feu de signalisation représenté en figure 1, - la figure 4 représente une vue en coupe transversale d'un feu de signalisation selon une variante de réalisation de l'invention, - la figure 5 représente une vue en coupe suivant A du feu de signalisation représenté en figure 4,
La figure 1 présente un feu de signalisation selon l'invention. Il est intégré dans un logement (9) de la carrosserie d'un véhicule à moteur. Ce feu de signalisation est composé d'un boîtier (6) sur lequel est disposé une vitre (7) extérieure. L'ensemble boîtier 1 vitre est assemblé par exemple par clippage. Le boîtier (6) du feu est fixé sur la carrosserie par l'intermédiaire d'un système de type vis 1 écrou (11). La surface (12) intérieure de ce boîtier est du type totalement réfléchissant et de forme orientée pour diriger par réflection la totalité des faisceaux lumineux émis par la source (1) émettrice. Compte tenu de sa fonction, la surface (12) intérieure du boîtier (6) est communément nommée réflecteur ou surface réfléchissante. La vitre (7) est conformée de telle sorte qu'elle intégre en son centre la source (1) émettrice de faisceaux lumineux ainsi qu'un élément (8) rétroréfléchissant, Other features and advantages will appear on reading the description below made with reference to the figures in which: - Figure 1 shows a cross-sectional view of a signal light according to the invention, - Figure 2 shows a detailed cross-sectional view of a mounting bracket for light-emitting diodes, - Figure 3 shows a sectional view along A of the signaling light shown in Figure 1, - Figure 4 shows a cross-sectional view of a light signaling device according to an alternative embodiment of the invention, - Figure 5 shows a sectional view along A of the signaling light shown in Figure 4,
Figure 1 shows a signal light according to the invention. It is integrated in a housing (9) of the body of a motor vehicle. This signaling light is composed of a housing (6) on which is arranged an external window (7). The housing unit 1 window is assembled for example by clipping. The housing (6) of the light is fixed to the body by means of a screw 1 nut type system (11). The interior surface (12) of this housing is of the totally reflecting type and of oriented shape for directing by reflection all of the light beams emitted by the emitting source (1). Given its function, the interior surface (12) of the housing (6) is commonly known as a reflector or reflecting surface. The window (7) is shaped so that it integrates in its center the source (1) emitting light beams as well as a retroreflective element (8),

<Desc/Clms Page number 4><Desc / Clms Page number 4>

plus communément nommé catadioptre. La vitre (7) est ainsi moulée pour accueillir et maintenir le support (2) de fixation des diodes (1) électroluminescentes et le catadioptre (8). En effet, la géométrie des formes obtenues par moulage du voyant laisse apparaître en son centre une cannelure (15). Dans le fond de cette cannelure est disposé l'élément (8) rétroréfléchissant qui est orienté de telle sorte que les différentes facettes le constituant sont vers l'extérieur du véhicule, afin d'assurer le réfléchissement d'une source lumineuse projetée en direction du feu de signalisation. De plus, cette cannelure présente des surfaces d'appui qui permettent la fixation du support (2) de maintien de la source (1) émettrice de faisceaux. Ainsi disposée, la source (1) lumineuse émet des faisceaux orientés vers le réflecteur (12) qui sont intégralement réfléchis pour être dirigés vers l'extérieur du véhicule, via la vitre (7) extérieure transparente.  more commonly known as a reflector. The window (7) is thus molded to receive and maintain the support (2) for fixing the light-emitting diodes (1) and the reflector (8). Indeed, the geometry of the shapes obtained by molding the sight glass reveals in its center a groove (15). In the bottom of this groove is arranged the retroreflective element (8) which is oriented so that the different facets constituting it are towards the outside of the vehicle, in order to ensure the reflection of a light source projected in the direction of the traffic light. In addition, this groove has bearing surfaces which allow the fixing of the support (2) for holding the beam-emitting source (1). Thus arranged, the light source (1) emits beams oriented towards the reflector (12) which are fully reflected so as to be directed towards the outside of the vehicle, via the transparent exterior window (7).

La vitre (7) est constituée d'une matière transparente présentant un indice de réfraction conforme à l'émission de faisceaux lumineux eu égard aux normes en vigueur. L'élément (8) rétroréfléchissant est inséré dans la vitre (7) durant la phase de moulage ou venu de moulage avec la vitre. The window (7) is made of a transparent material having a refractive index in accordance with the emission of light beams with regard to the standards in force. The retroreflective element (8) is inserted into the window (7) during the molding phase or comes from molding with the window.

La figure 2 détaille le support (2) de maintien de la source (1) émettrice de faisceaux. La source (1) émettrice est une diode électroluminescente (18) pourvue de deux cosses (3) de connection, une pour chaque pôle d'alimentation. Le maintien de la diode électroluminescente sur le support (2) est assuré par la présence de lamelles (4) déformables qui autorisent seulement le déplacement des languettes (3) dans un sens, à savoir celui obtenu lors de l'enfoncement de la diode sur son support de maintien. Ce dispositif de maintien garantit un montage rapide de la diode sur le support tout en établissant une liaison électrique qui permet l'alimentation en énergie de la diode.  Figure 2 details the support (2) for maintaining the source (1) emitting beams. The emitting source (1) is a light-emitting diode (18) provided with two connection lugs (3), one for each power pole. The maintenance of the light-emitting diode on the support (2) is ensured by the presence of deformable strips (4) which only allow the movement of the tongues (3) in one direction, namely that obtained when the diode is pressed on its support. This holding device guarantees rapid mounting of the diode on the support while establishing an electrical connection which allows the energy supply to the diode.

Comme on le voit sur la figure 3, le support (2) permet la fixation d'une succession de diodes électroluminescentes (18) accolées les unes aux autres de manière à créer une ligne de  As seen in Figure 3, the support (2) allows the attachment of a succession of light emitting diodes (18) attached to each other so as to create a line of

<Desc/Clms Page number 5><Desc / Clms Page number 5>

faisceaux lumineux pouvant être de forme quelconque. A l'extrémité du support (2), un connecteur (5) assure la liaison entre le feu et le circuit électrique du véhicule. Cette figure 3 montre également la position et la géométrie de l'élément (8) rétroréfléchissant qui recouvre les dimensions du support (2).  light beams which can be of any shape. At the end of the support (2), a connector (5) provides the connection between the light and the electrical circuit of the vehicle. This figure 3 also shows the position and the geometry of the retroreflective element (8) which covers the dimensions of the support (2).

De l'extérieur du véhicule, la source (1) émettrice de faisceaux lumineux est ainsi dissimulée derrière l'élément (8) rétroréfléchissant qui lui est adjacent. From outside the vehicle, the source (1) emitting light beams is thus hidden behind the retroreflective element (8) which is adjacent to it.

Les figures 4 et 5 sont relatives à une variante de réalisation d'un feu de signalisation dont la source émettrice de faisceaux lumineux émane d'un conduit (16) de lumière placé sur la vitre (7) extérieure transparente. Il s'agit d'une variante dans laquelle le dispositif émetteur de faisceaux lumineux est un conduit de lumière. Ce conduit de lumière est du type à fibre optique et la source lumineuse est la diode (13) électroluminescente unique positionnée à l'une de ses extrémités comme représenté en figure 5.  Figures 4 and 5 relate to an alternative embodiment of a signaling light whose source of light beams emanates from a light pipe (16) placed on the transparent window (7). This is a variant in which the light beam emitting device is a light pipe. This light pipe is of the optical fiber type and the light source is the single light-emitting diode (13) positioned at one of its ends as shown in FIG. 5.

Comme on le voit sur les figures, le conduit (16) de lumière est adjacent à l'élément (8) rétroréfléchissant. L'avantage premier de cette variante est de proposer une structure relativement simple favorisant un montage aisé. En effet, une rainure (17) longitudinale du voyant (7), ayant pour section un demi-cercle, accueille le conduit (16) lumineux. De plus, le maintien du conduit (16) sur le voyant (7) est assuré par un assemblage collé. L'élément (8) rétroréfléchissant est insérer dans la vitre (7) durant la phase de moulage du voyant ou venu de moulage avec celle-ci.  As can be seen in the figures, the light pipe (16) is adjacent to the retroreflective element (8). The primary advantage of this variant is to propose a relatively simple structure favoring easy assembly. Indeed, a longitudinal groove (17) of the sight glass (7), having a semicircle section, receives the light pipe (16). In addition, the maintenance of the conduit (16) on the sight glass (7) is ensured by a bonded assembly. The retroreflective element (8) is inserted into the glass (7) during the phase of molding of the sight glass or mold molding therewith.

La figure 5 détaille le positionnement de la source lumineuse (13) unique et le conduit lumineux (16) qui canalise le flux lumineux émit par la source (13). Le conduit (16) de lumière dirige et décompose le faisceau élémentaire émi par la diode (13) électroluminescente unique en une multitude de faisceaux lumineux. Cette décomposition est obtenue par des facettes (14) réfléchissantes disposées par usinage dans le conduit de lumière. Ces facettes (14) répartissent de manière uniforme le flux transitant au travers du conduit (16) de lumière  FIG. 5 details the positioning of the single light source (13) and the light pipe (16) which channels the light flux emitted by the source (13). The light pipe (16) directs and decomposes the elementary beam emitted by the single light-emitting diode (13) into a multitude of light beams. This decomposition is obtained by reflecting facets (14) arranged by machining in the light pipe. These facets (14) uniformly distribute the flux passing through the light pipe (16)

sur toute la surface du réflecteur. Le réflecteur redirige ensuite ces faisceaux au travers de la vitre (7) extérieure transparente afin d'obtenir le caractère esthétique voulu.  over the entire surface of the reflector. The reflector then redirects these beams through the transparent outer window (7) in order to obtain the desired aesthetic character.

Enfin, bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits. Finally, although the invention has been described in connection with particular embodiments, it includes all the technical equivalents of the means described.
