Abstract

MODULE LUMINEUX AVEC AFFICHAGE PAR LED OPTIMISÉ POUR APPLICATION AUTOMOBILE L’invention a trait à un module lumineux pour véhicule automobile, comprenant un dispositif optique de projection (12) avec un foyer, une face d’entrée et une face de sortie ; un imageur (10) formant une matrice de sources lumineuses, disposé entre le foyer et la face d’entrée de manière à ce que le dispositif optique de projection (12) puisse projeter une image agrandie dudit imageur (10) ; dans lequel l’imageur (10) présente une largeur l et une hauteur h, la face d’entrée et/ou la face de sortie présentent une largeur L et une hauteur H, où L>l, H>h, et L-l>H-h, de manière à ce que le module lumineux présente un champ de vue horizontal supérieur à un champ de vue vertical, lorsque ledit module lumineux est orienté en position de montage sur le véhicule automobile. (Figure à publier avec l'abrégé : Figure 4)LIGHT MODULE WITH OPTIMIZED LED DISPLAY FOR AUTOMOBILE APPLICATION The invention relates to a light module for a motor vehicle, comprising an optical projection device (12) with a focus, an input face and an output face; an imager (10) forming a matrix of light sources, arranged between the focus and the input face such that the optical projection device (12) can project an enlarged image of said imager (10); wherein the imager (10) has a width l and a height h, the input face and/or the output face have a width L and a height H, where L>l, H>h, and L-l>H-h, such that the light module has a horizontal field of view greater than a vertical field of view, when said light module is oriented in the mounting position on the motor vehicle.
