Abstract

L'invention concerne un dispositif lumineux (1) pour véhicule comprenant un boîtier (10), un support (12) comprenant une source lumineuse (13) pour émettre des rayons lumineux, un système optique (14) pour former un faisceau lumineux à partir desdits rayons lumineux, et comprenant : - un élément optique primaire (140) disposé en partie en regard de ladite source lumineuse (13) ; - un élément optique secondaire (141) disposé en regard dudit élément optique primaire (140), relié avec lui via un pont de liaison (142) et comprenant une face d'entrée (141a) avec des échelons de Fresnel et une face de sortie (141b) ; Caractérisé en ce que ledit pont de liaison (142) comprend un motif optique (142a) avec une face d'entrée perpendiculaire à une partie des rayons lumineux traversant ledit élément optique primaire de sorte qu'ils se propagent sans réfraction ni déviation au travers dudit pont de liaison jusqu'à ladite face de sortie.
