Abstract

La présente invention concerne lumineux pour véhicule automobile (1), comprenant une source lumineuse (5), un imageur (17) à cristaux liquides (LCD), et un système optique intercalé suivant le trajet des rayons lumineux issus de la source lumineuse (5) entre le source lumineuse (5) et l'imageur (17) de sorte à transmettre au moins une partie des rayons lumineux issus de la source lumineuse (5) vers une face d'entrée (18) de l'imageur (17), caractérisé en ce que le système optique comprend un dioptre d'entrée (9) présentant une première courbure (11) qui est de section concave suivant un premier plan (10) et un dioptre de sortie (13) présentant une deuxième courbure (15) qui est de section concave selon un deuxième plan (14), le deuxième plan (14) étant perpendiculaire au premier plan (10), la première courbure (11) et la deuxième courbure (15) étant configurées pour produire en sortie du dioptre de sortie (13) des divergences optiques d'amplitudes différentes suivant le premier plan (10) et le deuxième plan (14).
