Abstract

L'invention vise un dispositif d'émission lumineuse (10) pour véhicule automobile comprenant un dispositif d'émission de rayons lumineux (12), une matrice de micro-miroirs (14), un contrôleur (16) des micro-miroirs (22) et une optique de mise en forme (18). Le contrôleur (16) commande les micro-miroirs (22) selon deux consignes (34 ; 36), correspondant à des intensités lumineuses différentes réfléchies par un micro-miroir (22) vers l'optique de mise en forme (18), pour former une figure (F14) sur la matrice de micro-miroirs (14). La figure (F14) comprend, à une extrémité latérale (141 ; 142) de la matrice de micromiroirs (14), un motif (50) avec un premier micro-miroir (22) commandé selon la première consigne (34), situé plus près de l'extrémité latérale (141 ; 142) qu'un deuxième micro-miroir (22) commandé selon la deuxième consigne (36). L'invention se rapporte également à un procédé d'éclairage au moyen d'un tel dispositif d'émission lumineuse (10).
