Abstract

Dispositif d'éclairage, notamment pour véhicule automobile, comprenant au moins un module présentant un axe optique O, chaque module comportant : - une source lumineuse 8 configurée pour émettre un faisceau lumineux selon une direction globale d'allure sensiblement sécante à l'axe optique O, - un guide d'orientation de la lumière apte à diriger le faisceau lumineux émis par ladite source lumineuse 8 de façon sensiblement parallèle audit axe optique O en sortie dudit guide et apte à former une coupure dans ledit faisceau. Ce dispositif se caractérise en ce qu'il comprend une unique portion de sortie dudit faisceau lumineux dont la surface de sortie 3 est continue en courbure, et qui est commune à tous les modules.
