Abstract

The light unit has the lamp (3) and the transparent panel (5) for the dispersion of the beam leaving the lamp. The lamp is positioned in such a way, that the light issuing from it enters the edge of the panel across its thickness. Reflecting units (10) are provided for the diffraction of the light beam (R) in a mainly vertical direction. The lamp is arranged to stand opposite to an edge of the panel (5).

Description

La présente invention concerne un feu pour véhicules automobiles comprenant une lampe et une plaque (ou vitre) transparente destinée à diffuser les rayons lumineux émis par la lampe. The present invention relates to a motor vehicle light comprising a lamp and a transparent plate (or window) intended to diffuse the light rays emitted by the lamp.

Il est connu que l'on s'intéresse à des feux, particulièrement des feux de signalisation, qui possi- dent un encombrement limité dans le sens de la propagation du faisceau lumineux et qui possèdent, à l'état éteint, une couleur différente de celle du faisceau lumi- neux qu'ils émettent. La première exigence résulte, soit du fai-t que ces feux doivent être montés dans des zones restreintes, soit du fait que l'on cherche à simplifier la forme des éléments de carrosserie qui sont destinés à recevoir ces feux. En effet, un feu d'-6paisseur réduite peut être fixé à la carrosserie sans qu'il soit nécessaire de prévoir un trou ni un renfoncement particulier au niveau de ce feu. It is known that we are interested in lights, particularly signaling lights, which have a limited size in the direction of propagation of the light beam and which have, in the off state, a color different from that of the light beam they emit. The first requirement results either from the fact that these lights must be mounted in restricted areas, or from the fact that one seeks to simplify the shape of the bodywork elements which are intended to receive these lights. Indeed, a light of reduced thickness can be fixed to the bodywork without the need to provide a hole or a particular recess at the level of this light.

La deuxième exigence résulte de raisons esthdti- ques, en ce sens que la couleur de l'élément diffuseur du feu da signalisation, qui est rouge ou orange selon la fonction, ne s'harmonise pas toujours avec la couleur de la carrosserie. The second requirement results from aesthetic reasons, in the sense that the color of the signaling light diffusing element, which is red or orange depending on the function, does not always match the color of the bodywork.

Pour résoudre la première exigence, on a déjà réalisé des feux possédant des réflecteurs dune épaisseur réduite mais, naturellement, on n'a pas pu franchir certaines limites, d'une part en raison d'exigences de réflexion optique et, d'autre part et surtout, en raison de l'encombrement de la lampe et du diffuseur lui-même. To solve the first requirement, we have already made lights with reflectors of reduced thickness but, naturally, we could not cross certain limits, on the one hand because of optical reflection requirements and, on the other hand and above all, due to the size of the lamp and of the diffuser itself.

Pour satisfaire la deuxibme exigence, on a adopté des diffuseurs colorés qui portent sur leur surface visible, un réticule opaque à la lumière, possédant la même couleur que la carrosserie ou une couleur qui s'harmonise avec celle de la carrosserie. Cette solution.pré- sente les inconvénients d'occulter partiellement le flux lumineux et de ne pas masquer entièrement la coloration de l'élément diffuseur.  To meet the second requirement, colored diffusers have been adopted which bear on their visible surface a reticle opaque to light, having the same color as the bodywork or a color which harmonizes with that of the bodywork. This solution has the drawbacks of partially obscuring the luminous flux and of not completely masking the coloring of the diffusing element.

Le but de l'invention est de fournir un feu, en particulier, un feu de signalisation, qui résolve les
problèmes précités tout en étant d'une construction sim-
ple et économique.The object of the invention is to provide a light, in particular a signaling light, which resolves the
aforementioned problems while being of a simple construction
full and economical.

Le feu selon l'invention est car-actérisé en ce -que la lampe est disposée d telle manière que ses
rayons lumineux tombent sur la plaque dans le sens de
son épaisseur et en ce qu'il est prévu des moyens réflé
chissants qui dévient ces rayons lumineux dans une direc
tion sensiblement- perpendiculaire à la plaque.The fire according to the invention is car-activated in that the lamp is arranged in such a way that its
light rays fall on the plate in the direction of
its thickness and in that it is provided with reflected means
wrinkles which deflect these light rays in a direc
tion substantially- perpendicular to the plate.

La lampe est de préférence placée face à l'un
des bords de la plaque et les moyens réfléchissants sont
incorporés dans la plaque elle-même.The lamp is preferably placed facing one
edges of the plate and the reflecting means are
incorporated into the plate itself.

Ceci permet à la plaque du diffuseur de se com
porter sensiblement comme une fibre optique, c'est-à-di
re de transmettre la lumière dans son épaisseur par des
réflexions successives des rayons lumineux à l'interface
verre/air. L'utilisation de moyens réfléchissants permet
de dévier une partie des rayons lumineux transversale
ment à la plaque pendant leur parcours de manière à les
faire émerger de la plaque avec une intensité presque
constante.This allows the diffuser plate to be com
wear substantially like an optical fiber, i.e.
re to transmit light in its thickness by
successive reflections of light rays at the interface
glass / air. The use of reflective means allows
to deflect part of the transverse light rays
lie to the plate during their journey so as to
emerge from the plate with an intensity almost
constant.

Selon une autre caractéristique, les moyens ré
fléchissants sont constitués par des sillons rectilignes
sensiblement parallèles entre eux, formés sur une face
de la plaque et possédant un profil en V, les parois des
sillons qui sont dirigés vers la lampe formant un angle
obtus avec la surface de ladite face.According to another characteristic, the means re
bending consist of rectilinear furrows
substantially parallel to each other, formed on one side
of the plate and having a V-shaped profile, the walls of the
grooves which are directed towards the lamp forming an angle
obtuse with the surface of said face.

Ceci permet de former lesdits moyens d'une- fa
çon simple et économique, par moulage ou par fraisage
des surfaces de la plaque.This makes it possible to form said means in a fa
simple and economical lesson, by molding or milling
of the plate surfaces.

La plaque du feu de signalisation à lumière co
lorée peut être incolore et, dans ce cas, on interpose
entre la lampe et la plaque un filtre coloré disposé
dans une position telle qu'il soit invisible de l'exté-
rieur. Traffic light plate light co
lorée can be colorless and, in this case, we interpose
between the lamp and the plate a colored filter placed
in a position such that it is invisible from outside
laughing.

Ceci permet de satisfaire les exigences esthéti- ques précitées relatives à l'harmonisation chromatique en ce sens que, lorsque le feu est éteint, la plaque transparente peut, par exemple, laisser voir la couleur de la carrosserie sous-jacente.  This makes it possible to satisfy the above-mentioned aesthetic requirements relating to chromatic harmonization in the sense that, when the light is out, the transparent plate can, for example, reveal the color of the underlying bodywork.

D'autres caractéristiques et avantages de l'invent ion seront mieux compris à la lecture de la description qui va suivre, d'un exemple de réalisation en se référant aux dessins annexés, sur lesquels,
la figure 1 est une vue en perspective en partie en coupe du feu monté sur la carrosserie d'un vehicule automobile
la figure 2 est une coupe selon la ligne II-II de la figure 1
la figure 3 est un détail agrandi de la figure 2.Other characteristics and advantages of the invention will be better understood on reading the description which follows, of an exemplary embodiment with reference to the appended drawings, in which,
Figure 1 is a perspective view partly in section of the fire mounted on the body of a motor vehicle
Figure 2 is a section along line II-II of Figure 1
FIG. 3 is an enlarged detail of FIG. 2.

Sur les dessins, on a indiqué en 1 un feu de signalisation de véhicules automobiles, par exemple un feu émettant une lumière. rouge, dont l'allumage est commandé par la pédale de frein. Le feu 1 est fixé à une partie arrière 2 de la carrosserie d'un véhicule automobile et il comprend une lampe 3, up réflecteur parabolique 4 et une plaque transparente quadrangulaire incolore 5. Le filament de la lampe 3 est placé sensiblement au foyer du réflecteur 4. Naturellement le réflecteur 4 n'est pas nécessaire pour le fonctionnement du feu mais il est de toute façon utile pour améliorer le rendement optique du feu, c'est-à-dire le rapport entre l'énergie lumineuse émise par la lampe et l'énergie lumineuse qui émerge effectivement du -f eu .  The drawings show at 1 a motor vehicle signaling light, for example a light emitting light. red, the ignition of which is controlled by the brake pedal. The light 1 is fixed to a rear part 2 of the body of a motor vehicle and it comprises a lamp 3, up parabolic reflector 4 and a transparent colorless quadrangular plate 5. The filament of the lamp 3 is placed substantially at the focus of the reflector 4. Naturally the reflector 4 is not necessary for the operation of the light but it is in any case useful for improving the optical efficiency of the light, that is to say the ratio between the light energy emitted by the lamp and the light energy that actually emerges from the -f had.

La lampe 3 est placée à proximité d'un c8té 6 de la plaque 5 et elle est sensiblement dans le même plan que cette plaque. Un filtre coloré 7 est interposé entre la lampe 3 et la plaque 5. The lamp 3 is placed near a side 6 of the plate 5 and it is substantially in the same plane as this plate. A color filter 7 is interposed between the lamp 3 and the plate 5.

Toutefois, ce filtre peut être supprimé dans le cas où la plaque 5 est colorée Sur sa face 9 dirigée vers la carrosserie, la plaque 5 présente une série de sillons rectilignes 10 disposés parallèlement au côté 6. However, this filter can be omitted in the case where the plate 5 is colored. On its face 9 facing the body, the plate 5 has a series of rectilinear grooves 10 arranged parallel to the side 6.

Les sillons 10 présentent une section en V ; l'une des.The grooves 10 have a V-shaped section; one of.

deux parois de chaque sillon, plus précisément, la paroi 11 dirigée vers le côté 6, forme un angle obtus avec la face 9. Parallèlement à autre face 12 de la plaque 5, est disposé un élément diffuseur 13 présentant des dioptres convergents 14, qui sont disposés sur la surface de ce diffuseur 13 qui est dirigée vers la face 12 de la plaque 5. L'utilisation de l'élément diffuseur 13 ntest pas indispensable, en ce sens que les rayons lumineux sortent de la plaque 5 avec une direction qui est déjà correcte.two walls of each groove, more precisely, the wall 11 directed towards the side 6, forms an obtuse angle with the face 9. Parallel to another face 12 of the plate 5, is arranged a diffuser element 13 having converging dioptres 14, which are arranged on the surface of this diffuser 13 which is directed towards the face 12 of the plate 5. The use of the diffuser element 13 is not essential, in the sense that the light rays exit the plate 5 with a direction which is already correct.

Lorsque le feu est allumé, comme représenté sur la figure 2, les rayons lumineux R provenant de la - lam- pe, soit directement, soit après s'être réfléchis sur le réflecteur parabolique 4, traversent. le filtre coloré 7 et pénètrent dans la plaque 5 à travers le côté 6. Ainsi qu'on peut le voir égalemenent sur la figure 3, une partie des rayons lumineux colorés 5 subit une réflexion totale, en raison du faible angle d'incidence, sur l'interface verre/air 9. Certains des rayons sont réfléchis par la surface 12 et certains sont réfléchis par les pa rois ll de-s sillons 10. Ces derniers émergent de la plaque 5 au niveau de la surface 12 et traversent ensuite l'élément diffuseur 13. When the light is on, as shown in FIG. 2, the light rays R coming from the lamp, either directly or after being reflected on the parabolic reflector 4, pass through. the colored filter 7 and penetrate into the plate 5 through the side 6. As can also be seen in FIG. 3, part of the colored light rays 5 undergoes total reflection, due to the small angle of incidence, on the glass / air interface 9. Some of the rays are reflected by the surface 12 and some are reflected by the walls ll of the grooves 10. These emerge from the plate 5 at the surface 12 and then pass through the diffuser element 13.

En choisissant convenablement la distance d'écartement des sillons 10 et l'inclinaison des parois 11, il est possible d'obtenir un rapport approprié entre la quantité de lumière qui se propage par réflexions successives dans la plaque 'et la quantité de lumière qui est progressivement projetée à l'extérieur par réflexion, de manière à faire apparattre toute la surface 12 de la plaque uniformément lumineuse. By appropriately choosing the distance between the grooves 10 and the inclination of the walls 11, it is possible to obtain an appropriate ratio between the amount of light which is propagated by successive reflections in the plate and the amount of light which is gradually projected to the outside by reflection, so as to make the entire surface 12 of the plate uniformly appear.

Pour obtenir une réflexion plus intense des rayons R, les parois 11 des sillons 10, ou éventuelle ment toute la surface 9, peuvent ou peut être rendue(s) réfléchissante(s) par argenture ou par une autre technique analogue. To obtain a more intense reflection of the R rays, the walls 11 of the grooves 10, or possibly the entire surface 9, can or can be made (s) reflective (s) by silvering or by another similar technique.

Bien entendu, diverses modifications pourront être apportées par l'homme de l'art au dispositif qui vient d'être décrit uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention ; par exemple la plaque peut prendre une forme courbe ou en ligne brisée, et les sillons 10 peuvent présenter des configurations différentes de celle qui a été décrite.  Of course, various modifications may be made by those skilled in the art to the device which has just been described solely by way of nonlimiting example without departing from the scope of the invention; for example the plate may take a curved or broken line shape, and the grooves 10 may have different configurations from that which has been described.
