Abstract

L'invention concerne un dispositif d'éclairage (600), notamment pour véhicule automobile comprenant : une lentille de projection (604; 603.1-603.3) comprenant une surface d'entrée et une surface de sortie ; au moins deux sources lumineuses (602.1 ; 602.2 ; 601) apte à émettre de la lumière au moins dans des directions principales d'émission respectives, les sources lumineuses étant positionnées de manière à ce que la surface d'entrée de la lentille de projection reçoive de la lumière issue des sources lumineuses, les directions principales d'émission des sources lumineuses formant chacune un angle (606) d'au moins 15° par rapport à un axe optique (607) et les sources lumineuses étant positionnées de part et d'autre de l'axe optique; la lentille de projection étant conformée pour diriger la lumière reçue par la surface d'entrée vers la surface de sortie de manière à former un faisceau lumineux, le faisceau lumineux comprenant une zone centrale sensiblement dans l'axe optique dont une intensité lumineuse est inférieure à des intensités lumineuses respectives de zones de part et d'autre de la zone centrale.
