According to the invention, at least one uncoloured transparent bar (55) extending parallel or with a small inclination with respect to the overall direction (X-X) of the beam leaving the mask is furthermore provided in at least one side region of the mask, the said bar forming a light guide for the radiation output by the source in its direction and having an inclined free end face (56) for ensuring, by total reflection, reemission of the said radiation in a general direction essentially transverse to the said overall direction. <IMAGE>

Description

La présente invention a trait d'une façon générale aux feux de signalisation de véhicules automobiles. Elle concerne plus particulièrement les feux susceptibles d'émettre un rayonnement coloré mais présentant, lorsqu'ils sont éteints, un aspect essentiellement incolore. Il peut s'agir notamment d'un feu clignotant avant, disposé au voisinage d'un projecteur et dont on recherche une certaine continuité d'aspect avec ledit projecteur lorsque le projecteur et le feu sont éteints.The present invention relates generally to the signaling lights of motor vehicles. It relates more particularly to lights capable of emitting colored radiation but having, when they are extinguished, an essentially colorless appearance. It may in particular be a front flashing light, disposed in the vicinity of a headlamp and for which a certain continuity of appearance is sought with said headlamp when the headlamp and the light are off.

Il existe actuellement plusieurs techniques pour rendre incolore, lorsqu'il est éteint, l'aspect d'un feu à émission colorée. L'une de ces techniques consiste à prévoir un écran translucide ayant la coloration appropriée en avant de la source lumineuse et d'un éventuel réflecteur, ainsi qu'un masque en avant dudit écran, à former sur la face extérieure de ce masque, par exemple par sérigraphie, des zones opaques, par exemple réfléchissantes (obtenues par dépôt d'aluminium), et à prévoir du côté intérieur du masque des dispositifs optiques capables de concentrer la lumière colorée ayant traversé l'écran vers les zones non opacifiées, par exemple en forme de bandes.There are currently several techniques for making the appearance of a colored emission fire colorless when it is out. One of these techniques consists in providing a translucent screen having the appropriate coloring in front of the light source and of a possible reflector, as well as a mask in front of said screen, to be formed on the external face of this mask, by for example by screen printing, opaque areas, for example reflective (obtained by deposition of aluminum), and to provide on the inside of the mask optical devices capable of concentrating the colored light having passed through the screen towards the non-opacified areas, for example in the form of bands.

On se réfèrera notamment aux documents EP-A-0 274 325 et au modèle d'utilité allemand No. 1 833 150 pour plus de détail sur ces techniques. Une technique analogue est décrite dans EP-A-0 066 438.Reference is made in particular to documents EP-A-0 274 325 and to the German utility model No. 1 833 150 for more details on these techniques. A similar technique is described in EP-A-0 066 438.

Un inconvénient de l'art antérieur réside cependant en ce que le faisceau lumineux produit par le feu est excessivement directif suivant son axe optique, c'est-à-dire que la visibilité latérale du feu est insuffisante, jusqu'à être non conforme aux règlements en vigueur en matière de photométrie.A drawback of the prior art however lies in the fact that the light beam produced by the light is excessively directive along its optical axis, that is to say that the lateral visibility of the light is insufficient, until it does not conform to the photometry regulations in force.

On connaît également par JP-A 21 72 101 un feu de signalisation comportant un barreau de renvoi séparé des moyens optiques conventionnels de traitement de la lumière; un tel barreau rajouté ne saurait cependant être incorporé par l'homme de l'art de façon évidente à un feu du type mentionné plus haut sans compromettre ses caractéristiques de faisceau coloré et d'aspect incolore lorsqu'il est éteint.JP-A 21 72 101 also discloses a signaling light comprising a return rod separated from conventional optical means for processing light; such an added bar cannot however be incorporated by a person skilled in the art in an obvious way into a fire of the type mentioned above without compromising its characteristics of colored beam and colorless appearance when it is extinguished.

La présente invention vise à pallier les inconvénients de la technique antérieure.The present invention aims to overcome the drawbacks of the prior art.

Elle propose à cet effet un feu de signalisation ayant les particularités de la revendication 1.To this end, it proposes a signaling light having the features of claim 1.

D'autres aspects, buts et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante d'un certain nombre de modes de réalisation concrets de celle-ci, donnée à titre d'exemple et faite en référence aux dessins annexés, sur lesquels:

  • la figure 1 est une vue en coupe horizontale partielle et schématique d'un feu de signalisation selon l'invention,

  • la figure 4 est une vue en coupe horizontale axiale d'un feu de signalisation selon un troisième mode d'exécution de l'invention, et
  • la figure 5 est une vue analogue à la figure 1, d'une variante de réalisation.
Other aspects, aims and advantages of the present invention will appear better on reading the following detailed description of a number of concrete embodiments thereof, given by way of example and made with reference to the accompanying drawings , on which ones:
  • FIG. 1 is a partial and schematic horizontal section view of a signaling light according to the invention,
  • FIG. 2 is a view in axial horizontal section of a signaling light according to a first embodiment of the invention,
  • FIG. 3 is a view in axial horizontal section of a signaling light according to a second embodiment of the invention,
  • FIG. 4 is a view in axial horizontal section of a signaling light according to a third embodiment of the invention, and
  • Figure 5 is a view similar to Figure 1, of an alternative embodiment.

En référence tout d'abord à la figure 1, on a représenté une partie d'un feu de signalisation avant, notamment un feu clignotant indicateur de direction avant, destiné à être accolé par exemple latéralement à un projecteur. Le feu comprend une source et un miroir récupérateur de flux (non représentés), un écran translucide 40 traversé par le rayonnement R issu du couple source/miroir, destiné à donner à ce rayonnement la coloration ambre requise, un masque 50 et une glace, globe ou voyant de fermeture (non représenté).Referring firstly to Figure 1, there is shown a part of a front signaling light, in particular a front direction indicator flashing light, intended to be attached for example laterally to a headlight. The fire includes a source and a mirror flow recuperator (not shown), a translucent screen 40 crossed by the radiation R from the source / mirror pair, intended to give this radiation the required amber coloration, a mask 50 and a lens, globe or closing light (not shown ).

Le masque 50 comporte sur sa face externe un profil en créneaux de manière à former un ensemble de bandes saillantes 51 dont les faces d'extrémité comportent un revêtement opaque 51a, de préférence réfléchissant, formé par exemple par sérigraphie. Dans les bandes en creux 52 s'étendant entre deux bandes saillantes adjacentes, aucun revêtement n'est prévu et la lumière peut passer.The mask 50 has on its external face a profile in crenellations so as to form a set of projecting bands 51 whose end faces comprise an opaque coating 51a, preferably reflective, formed for example by screen printing. In the recessed strips 52 extending between two adjacent projecting strips, no coating is provided and the light can pass.

Sur la face interne du masque 50 sont formées, en correspondance avec les bandes en creux 52, des stries à profil circulaire 53 qui sont destinées à faire converger le rayonnement incident R en direction desdites bandes 52.On the internal face of the mask 50 are formed, in correspondence with the hollow bands 52, ridges with circular profile 53 which are intended to converge the incident radiation R in the direction of said bands 52.

Le rayonnement qui sort du masque 50 traverse ensuite la glace, pour former le faisceau de signalisation.The radiation leaving the mask 50 then crosses the ice, to form the signaling beam.

Un tel masque 50 a pour objet principal de donner au feu, lorsqu'il est éteint, un aspect incolore et relativement brillant qui s'harmonise bien avec l'aspect, éteint, d'un projecteur situé au voisinage du feu, en masquant autant que possible l'écran translucide coloré 40.The main purpose of such a mask 50 is to give the fire, when it is extinguished, a colorless and relatively bright appearance which harmonizes well with the aspect, extinguished, of a spotlight located in the vicinity of the fire, by masking as much as possible the translucent colored screen 40.

Du fait de la configuration du masque 50, le rayonnement issu de celui-ci est dirigé majoritairement suivant une direction A-A parallèle à l'axe optique du feu, et l'on comprend que les exigences photométriques en matière d'émission lumineuse en direction latérale sont remplies de façon tout à fait insatifaisante.Due to the configuration of the mask 50, the radiation coming from the latter is mainly directed in a direction AA parallel to the optical axis of the light, and it is understood that the photometric requirements in terms of light emission in the lateral direction are fulfilled in an utterly insatiable way.

Selon la présente invention, le feu comprend, dans au moins l'une des régions latérales du masque 50, un barreau 55 de matière transparente formant guide de lumière, s'étendant vers l'avant du feu parallèlement ou avec une faible inclinaison par rapport à l'axe optique. Ce barreau se termine par une face biseautée 56, inclinée par exemple à 45° par rapport à l'axe optique, de manière à assurer, par réflexion interne totale, une réémission, vers le côté du feu, du rayonnement entrant dans ledit barreau par une face interne 57.According to the present invention, the light comprises, in at least one of the lateral regions of the mask 50, a bar 55 of transparent material forming a light guide, extending towards the front of the light parallel or with a slight inclination relative to to the optical axis. This bar ends with a bevelled face 56, inclined for example at 45 ° relative to the optical axis, so as to ensure, by total internal reflection, a retransmission, towards the side of the light, of the radiation entering said bar via an internal face 57.

De façon particulièrement avantageuse, comme illustré, le barreau 55 est réalisé d'un seul tenant avec le masque 50, en s'étendant vers l'avant à partir de la région d'un bord latéral de celui-ci.In a particularly advantageous manner, as illustrated, the bar 55 is produced in a single piece with the mask 50, extending forward from the region of a lateral edge thereof.

Il est également préférable que la face inclinée 56 de réflexion latérale soit dépolie, de manière à assurer en même temps un effet de diffusion de la lumière guidée par le barreau, ceci afin que la lumière déviée couvre latéralement un champ angulaire important tel que requis par les règlements.It is also preferable for the inclined side 56 of lateral reflection to be frosted, so as to at the same time ensure a scattering effect of the light guided by the bar, so that the deflected light covers laterally a large angular field as required by the rules.

On va maintenant décrire en référence aux figures 2 à 4 des formes de réalisation concrètes d'un feu réalisé conformément à l'invention.We will now describe with reference to Figures 2 to 4 concrete embodiments of a fire made in accordance with the invention.

Sur chacune de ces figures, la lampe est indiqué en 10, un socle, dont une partie constitue un miroir récupérateur de flux, en 20, et la glace ou voyant en 30, les autres parties ou composants portant les mêmes signes de référence que sur la figure 1.In each of these figures, the lamp is indicated at 10, a base, part of which constitutes a flux recovery mirror, at 20, and the glass or sight glass at 30, the other parts or components bearing the same reference signs as on Figure 1.

Dans la forme de réalisation de la figure 2, le bord latéral du masque 50 du côté extérieur (vers la droite sur la figure) du feu est légèrement en retrait par rapport à la transition entre le globe 30 et la carrosserie C du véhicule. Le barreau 55 est réalisé du côté extérieur du masque 50 et présente une étendue selon l'axe X-X suffisante pour faire saillie au-delà de cette transition, de manière à ce que le rayonnement guidé puis réfléchi sur la face 56 puisse sortir du feu latéralement sans obstacle.In the embodiment of Figure 2, the side edge of the mask 50 on the outer side (to the right in the figure) of the light is slightly recessed from the transition between the globe 30 and the body C of the vehicle. The bar 55 is produced on the outside of the mask 50 and has an extension along the axis XX sufficient to project beyond this transition, so that the radiation guided then reflected on the face 56 can exit the fire laterally without obstacle.

Dans la forme de réalisation de la figure 3, le barreau 55 s'étend à partir du bord latéral intérieur du masque 50, le long d'une joue latérale intérieure 21 définie par le socle 20 du feu. Dans ce cas, le barreau 55 s'étend vers l'avant dans une mesure suffisante pour que le rayonnement dévié latéralement puisse sortir par le globe 30 du feu avec une étendue angulaire Ω suffisante en direction de l'arrière du véhicule, par exemple de l'ordre de 30 à 45° par rapport à la normale Y-Y à l'axe optique X-X.In the embodiment of Figure 3, the bar 55 extends from the inner side edge of the mask 50, along an inner side cheek 21 defined by the base 20 of the light. In this case, the bar 55 extends forward enough to allow the laterally deflected radiation to exit the globe 30 of the light with a sufficient angular extent Ω towards the rear of the vehicle, for example of the order of 30 to 45 ° with respect to the normal YY to the optical axis XX.

La forme de réalisation représentée sur la figure 4 est similaire dans son principe à celle de la figure 2 : le barreau 55 est prévu du côte extérieur du masque 50. Dans cette réalisation, le feu clignotant et le projecteur associé partagent la même glace de fermeture 30.The embodiment shown in Figure 4 is similar in principle to that of Figure 2: the bar 55 is provided on the outer side of the mask 50. In this embodiment, the flashing light and the associated headlight share the same closing glass 30.

Dans les trois formes de réalisation concrètes ci-dessus, le barreau formant guide de lumière et déviateur 55 peut être réalisé d'un seul tenant, par exemple venu de moulage, avec le masque 50.In the three concrete embodiments above, the bar forming a light guide and deflector 55 can be made in one piece, for example molded, with the mask 50.

La présente invention permet de donner à un feu tel qu'un feu clignotant avant des propriétés satisfaisantes en matière d'émission lumineuse vers le côté, et ceci sans dégrader l'aspect du feu lorsqu'il est éteint. Plus précisément, du fait que le barreau 55 est réalisé en matière plastique incolore, il est relativement peu perceptible de l'extérieur lorsque le feu est éteint. En outre, l'écran coloré 40 situé en arrière est très peu visible à travers ledit barreau.The present invention makes it possible to give a lamp such as a front flashing lamp satisfactory properties in terms of light emission towards the side, and this without degrading the appearance of the lamp when it is extinguished. More specifically, because the bar 55 is made of colorless plastic, it is relatively invisible from the outside when the fire is out. In addition, the colored screen 40 located behind is very little visible through said bar.

Bien entendu, la présente invention n'est nullement limitée à la forme de réalisation décrite ci-dessus et représentée sur les dessins, mais l'homme de l'art saura y apporter toute variante ou modification conforme à son esprit.Of course, the present invention is in no way limited to the embodiment described above and shown in the drawings, but a person skilled in the art will know how to make any variant or modification in accordance with his spirit.

En particulier, un feu de signalisation selon la présente invention peut être équipé si on le souhaite de deux barreaux 55 s'étendant à partir des deux bords latéraux du masque 50, avec des étendues horizontales vers l'avant différentes (on combine dans ce cas les formes de réalisation des figures 2 et 3).In particular, a signaling light according to the present invention can be equipped, if desired, with two bars 55 extending from the two lateral edges of the mask 50, with different horizontal expanses towards the front (in this case, we combine the embodiments of Figures 2 and 3).

Selon une autre variante, illustrée sur la figure 5, on peut prévoir qu'un même barreau 55 soit équipé de plusieurs faces de renvoi inclinées 56a, 56b, 56c..., décalées les unes par rapport aux autres à la fois dans la direction longitudinale du barreau et dans sa direction transversale, de manière à obtenir une multiplication des lieux d'où est issue la lumière émise latéralement,pour produire une signalisation latérale moins brillante et plus homogène.According to another variant, illustrated in FIG. 5, it can be provided that the same bar 55 is equipped with several inclined return faces 56a, 56b, 56c ..., offset with respect to each other both in the direction longitudinal of the bar and in its transverse direction, so as to obtain a multiplication of the places from which the light emitted laterally comes, to produce a less brilliant and more homogeneous lateral signaling.

On observera pour terminer que la hauteur du ou des barreaux 55 peut être égale ou inférieure à celle du masque, l'homme de l'art étant à même de choisir une hauteur appropriée en fonction de considérations photométriques et esthétiques.Finally, it will be observed that the height of the bar (s) 55 may be equal to or less than that of the mask, the person skilled in the art being able to choose an appropriate height as a function of photometric and aesthetic considerations.
