Abstract

RACCORDEMENT ENTRE ZONES D’UN REFLECTEUR DE MODULE LUMINEUX à COUPURE L’invention a trait à un module lumineux (101), notamment pour véhicule automobile, comprenant une source lumineuse (104) apte à émettre des rayons lumineux ; une surface de réflexion (102.2) destinée à être recouverte d’un vernis et configurée pour réfléchir les rayons lumineux de manière à former un faisceau lumineux à coupure supérieure, ladite surface de réflexion comprenant une première zone (102.2.4, 102.2.6) s’étendant longitudinalement et configurée pour former une image lumineuse à coupure supérieure et une deuxième zone (102.2.3, 102.2.5) et une troisième zone (102.2.5, 102.2.7) s’étendant longitudinalement le long de la première zone (102.2.4, 102.2.6), respectivement de part et d’autre de ladite première zone, où la surface de réflexion (102.2) présente un profil transversal formant une marche descendante depuis la première zone (102.2.4, 102.2.6) vers chacune des deuxième (102.2.3, 102.2.5) et troisième (102.2.5, 102.2.7) zones.
