Abstract

L'invention concerne un module lumineux de véhicule automobile destiné à générer un faisceau lumineux projetant vers l'avant une image (I1). Ladite image (I1) comprend au moins une rangée horizontale (4, 5) d'unités d'illumination (Z1 à Z10; W1 à W10). Selon l'invention, le module lumineux est agencé de manière à ce qu'une première unité d'illumination (W8, W9, W10) de la rangée horizontale (4) d'unités d'illumination comprenne une extrémité inférieure (52) et/ou supérieure (51) qui est décalée verticalement par rapport à une extrémité respectivement inférieure (54) et/ou supérieure (53) d'une deuxième unité d'illumination (W1 à W7) de la même rangée.
