Abstract

L’invention concerne un dispositif d’éclairage (100) apte à réaliser un faisceau global pixelisé. Le dispositif comprend au moins deux sources lumineuses (102.1 ; 102.2), respectivement associées à au moins deux réflecteurs (101.1 ; 101.2), disposés l’un à coté de l’autre horizontalement. Selon l’invention, chaque réflecteur comprend au moins deux secteurs latéraux (101a ; 101c) à deux positions horizontales distinctes, et, pour chaque secteur latéral, une zone extrême du secteur latéral située vers l’extérieur du réflecteur est conformée pour réaliser une coupure nette d’un faisceau individuel issu du réflecteur.
