Abstract

Titre : Module lumineux à sources à partie émissive maximisée L’invention concerne un module lumineux pour véhicule automobile, comprenant : - une première rangée (10) de sources lumineuses juxtaposées selon une direction de juxtaposition (Y), configurée pour produire un premier faisceau de sortie (1) ; - un premier élément optique (30) doté d’une face d’entrée (31) configurée pour recevoir les rayons lumineux des sources de la première rangée (10) et d’une face de sortie (32) configurée pour projeter les rayons lumineux ,Les sources lumineuses de la première rangée (10) sont des sources électroluminescentes à partie émissive maximisée, et la face de sortie (32) du premier élément optique (30) comprend des premiers motifs (33) juxtaposés selon la direction de juxtaposition (Y) et pourvus d’un premier profil convexe suivant la direction de juxtaposition (Y) et d’un deuxième profil convexe suivant une deuxième direction perpendiculaire (Z) à la direction de juxtaposition (Y).
