Abstract

L’invention concerne un dispositif lumineux (1) pour véhicule (2) comprenant un module lumineux (10) pour générer des rayons lumineux primaires (R1), une glace de sortie (11), une structure de reliefs de découplage (12), caractérisé en ce qu’il comprend :- un écran intermédiaire (13) comprenant ladite structure de reliefs de découplage (12), disposé entre ledit module lumineux (10) et ladite glace de sortie (11), et possédant une première face (13.1) en regard dudit module lumineux (10) et une deuxième face (13.2) en regard de ladite glace de sortie (11), - ladite structure de reliefs de découplage (12) étant disposée sur la première face (13.1) dudit écran intermédiaire (13), la deuxième face (13.2) possédant une épaisseur (e2) non constante de sorte que les rayons lumineux primaires (R1) sortent d’elle dans une direction (r2) identique ou parallèle à une direction (r1) dans laquelle ils sont rentrés par ladite première face (13.1).
