Abstract
L'invention fournit un dispositif d'éclairage pour un véhicule automobile. Ce dispositif d'éclairage comprend un premier groupe de lumière, un second groupe de lumière configuré pour émettre de la lumière dans la même longueur d'onde que le premier groupe de lumière, une première couche de conversion de longueur d'onde, une seconde couche de conversion de longueur d'onde et un élément optique principal agencé pour recevoir la lumière projetée par les première et seconde couches de conversion de longueur d'onde et configuré pour projeter de la lumière à l'extérieur du dispositif d'éclairage. La première couche de conversion de longueur d'onde est agencée pour recevoir la lumière émise par le premier groupe de lumière et projeter la lumière dans une longueur d'onde différente de la lumière du premier groupe de lumière, tandis que la seconde couche de conversion de longueur d'onde est agencée pour recevoir la lumière émise par le second groupe de lumière et projeter la lumière dans une longueur d'onde différente de la lumière du second groupe de lumière et différente de la lumière projetée par la première couche de conversion de longueur d'onde.Figure pour l'abrégé : figure 1The invention provides a lighting device for a motor vehicle. This lighting device includes a first light group, a second light group configured to emit light in the same wavelength as the first light group, a first wavelength conversion layer, a second wavelength conversion layer and a main optical element arranged to receive the light projected by the first and second wavelength conversion layers and configured to project light outside the lighting device. The first wavelength converting layer is arranged to receive the light emitted from the first light group and project the light in a wavelength different from the light of the first light group, while the second converting layer of wavelength is arranged to receive the light emitted by the second light group and project the light in a wavelength different from the light of the second light group and different from the light projected by the first light conversion layer wavelength.Figure for the abstract: figure 1
