Abstract

L'invention a trait à un module lumineux (8) pour véhicule automobile, comprenant une source lumineuse (12) à semi-conducteur avec une surface éclairante généralement plane apte à émettre de la lumière suivant un axe d'émission perpendiculaire audit plan ; une surface de réflexion (14) apte à réfléchir la lumière émise par la source lumineuse (12) de manière à former, suivant un axe optique (16), un faisceau lumineux à coupure, et comprenant une zone centrale (14.1); et au moins une zone (14.2-14.5) latérale à la zone centrale (14.1) ; la ou au moins une (14.2, 14.3) des zones latérales est configurée pour former une image lumineuse à coupure horizontale.
