Abstract

L’invention concerne un élément optique monobloc pour dispositif lumineux de véhicule, comprenant une première partie formant un guide plat présentant une face d’entrée, l’élément optique comportant en outre une deuxième partie formant un guide de lumière s'étendant au moins en partie en regard de la face d’entrée et propre à assurer un éclairage sensiblement homogène de la face d’entrée en guidant des photons provenant d'une source lumineuse susceptible d’éclairer une zone d’alimentation de la deuxième partie vers la face d’entrée.
