État de la technique antérieureState of the prior art

On sait que les réglementations internationales imposent aux véhicules automobiles d’être pourvus à l'avant et à l’arrière de blocs optiques d’éclairage et de signalisation afin, d’une part, d’éclairer la route pour améliorer la visibilité du conducteur du véhicule, notamment en conditions nocturnes, et, d'autre part, de signaler la position du véhicule aux autres usagers de la route. Un bloc optique comporte classiquement au moins un boîtier destiné à être fixé sur la structure du véhicule et dans lequel est monté, directement ou par l'intermédiaire d'un support dédié, au moins un dispositif lumineux apte à assurer une fonction photométrique d’éclairage, comme, par exemple, un feu de route, un feu de croisement (dénommé également code), ou un feu de position (dénommé également veilleuse ou bien lanterne), ou bien encore une fonction photométrique de signalisation, comme, par exemple, un feu de recul, un feu stop ou un feu clignotant indicateur de changement de direction. Pour assurer de telles fonctions photométriques, certains blocs optiques actuels contiennent des lasers au lieu des traditionnelles ampoules à incandescence, notamment certains blocs optiques avant d’éclairage, par exemple certains feux diurnes. Cependant, les lasers actuels qui peuvent être utilisés dans les blocs optiques des véhicules automobiles sont limités en puissance et ne permettent pas de délivrer des niveaux d’intensité lumineuse qui sont prescrits par les réglementations qui s’applique en matière d’éclairage et de signalisation des véhicules automobiles (une intensité lumineuse de l’ordre de 400cd est par exemple prescrite pour les feux diurnes).We know that international regulations require motor vehicles to be equipped at the front and rear with optical lighting and signaling units in order, on the one hand, to illuminate the road to improve the driver's visibility. of the vehicle, particularly in nighttime conditions, and, on the other hand, to signal the position of the vehicle to other road users. An optical unit conventionally comprises at least one housing intended to be fixed on the structure of the vehicle and in which is mounted, directly or via a dedicated support, at least one light device capable of providing a photometric lighting function , such as, for example, a high beam, a low beam (also called code), or a position light (also called night light or lantern), or even a photometric signaling function, such as, for example, a reversing light, a brake light or a flashing light indicating change of direction. To provide such photometric functions, certain current optical units contain lasers instead of traditional incandescent bulbs, in particular certain front lighting optical units, for example certain daytime running lights. However, current lasers which can be used in the optical units of motor vehicles are limited in power and do not make it possible to deliver light intensity levels which are prescribed by the regulations which apply to lighting and signaling. motor vehicles (a light intensity of around 400cd is for example prescribed for daytime running lights).

L’invention vise à remédier à cette problématique. L’invention vise en particulier à fournir une solution pour, dans un bloc optique d’éclairage et/ou de signalisation d’un véhicule automobile, permettre l’utilisation d’un laser conventionnel tout en satisfaisant les prescriptions réglementaires en matière d’intensité lumineuse délivrée.The invention aims to remedy this problem. The invention aims in particular to provide a solution for, in an optical lighting and/or signaling unit of a motor vehicle, allowing the use of a conventional laser while satisfying the regulatory requirements in terms of intensity. light delivered.

Selon une variante, la lentille peut être en silicone.According to a variant, the lens can be made of silicone.

Selon une autre variante, la lentille peut être un ménisque convergent ou une lentille biconvexe.According to another variant, the lens may be a converging meniscus or a biconvex lens.

Description détaillée de l’inventionDetailed description of the invention

La illustre une vue de côté d’un assemblage 100 pour bloc optique d’éclairage et/ou de signalisation pour véhicule automobile selon l’invention. L’assemblage 100 selon l’invention comprend une fibre optique 101 destinée à être couplée à un laser qui est insérée dans une cavité 102 d’un support 103. La fibre optique 101 a un profil circulaire tandis que la cavité 102 du support 103 a un profil en U. En outre, une lentille 104 convergente et déformable, préférentiellement en silicone, forme avantageusement le plafond de la cavité 103, de sorte que la fibre optique 101 se trouve entre le fond de la cavité 102 et la lentille 104. La lentille 104 est avantageusement maintenue au support 103 uniquement par ses bords qui s’insèrent dans la cavité 102. La lentille 104 est préférentiellement un ménisque convergent, tel qu’illustré sur la figure. Alternativement, c’est une lentille biconvexe. Dans tous les cas, la lentille 104 fait converger les rayons lumineux générés par la fibre optique 101 et permet ainsi une augmentation de l’intensité lumineuse délivrée. En outre, le montage de l’assemblage 100 selon l’invention est particulièrement aisé. Pour ce faire, on doit d’abord insérer la fibre optique 101 dans la cavité 102 du support 103 et, ensuite, on n’a plus qu’à forcer les bords de la lentille 104 de chaque côté de la cavité 102.There illustrates a side view of an assembly 100 for an optical lighting and/or signaling unit for a motor vehicle according to the invention. The assembly 100 according to the invention comprises an optical fiber 101 intended to be coupled to a laser which is inserted into a cavity 102 of a support 103. The optical fiber 101 has a circular profile while the cavity 102 of the support 103 has a U-shaped profile. In addition, a converging and deformable lens 104, preferably made of silicone, advantageously forms the ceiling of the cavity 103, so that the optical fiber 101 is located between the bottom of the cavity 102 and the lens 104. lens 104 is advantageously held to the support 103 only by its edges which insert into the cavity 102. The lens 104 is preferably a converging meniscus, as illustrated in the figure. Alternatively, it is a biconvex lens. In all cases, the lens 104 converges the light rays generated by the optical fiber 101 and thus allows an increase in the light intensity delivered. In addition, the assembly of the assembly 100 according to the invention is particularly easy. To do this, we must first insert the optical fiber 101 into the cavity 102 of the support 103 and, then, we only have to force the edges of the lens 104 on each side of the cavity 102.

Par conséquent, grâce à l’invention, une solution est fournie pour, dans un bloc optique d’éclairage et/ou de signalisation d’un véhicule automobile, permettre l’utilisation d’un laser conventionnel tout en satisfaisant les prescriptions réglementaires en matière d’intensité lumineuse délivrée.Consequently, thanks to the invention, a solution is provided for, in an optical lighting and/or signaling unit of a motor vehicle, allowing the use of a conventional laser while satisfying the regulatory requirements regarding light intensity delivered.
