Abstract

Dispositif d’éclairage et/ou de signalisation L’invention concerne un dispositif (1) d’éclairage et/ou de signalisation d’un véhicule comprenant un guide de lumière (2) linéique qui présente une direction d’allongement longitudinale principale et une source de lumière (3), le guide de lumière (2) comprenant une face d’entrée (7) et une face de sortie (8) des rayons lumineux émis par la source de lumière (3), la face de sortie s’étendant le long de la direction d’allongement du guide de lumière, caractérisé en ce que la face d’entrée (7) est disposée à l’opposé de la face de sortie (8) et que la source de lumière (3) comprend une carte de circuit imprimé (4) sur laquelle est disposée une pluralité de microLEDs (5) formant une série linéaire (6) dans une direction parallèle à la direction d’allongement longitudinale principale du guide de lumière, au sein de laquelle les microLEDs (5) voisines sont espacées entre elle d’une distance (D) comprise entre 200 microns et 1 millimètre. Figure pour l’abrégé : Figure 1Lighting and / or signaling device The invention relates to a device (1) for lighting and / or signaling a vehicle comprising a linear light guide (2) which has a main longitudinal direction of elongation and a light source (3), the light guide (2) comprising an input face (7) and an output face (8) of the light rays emitted by the light source (3), the output face s' extending along the direction of elongation of the light guide, characterized in that the inlet face (7) is disposed opposite to the outlet face (8) and the light source (3) comprises a printed circuit board (4) on which is arranged a plurality of microLEDs (5) forming a linear series (6) in a direction parallel to the main longitudinal direction of elongation of the light guide, within which the microLEDs ( 5) neighbors are spaced apart by a distance (D) of between 200 microns and 1 millimeter.
