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. (Figure à publier avec l'abrégé : Figure 1)The invention relates to a light module (101), in particular for a motor vehicle, comprising a light source (104) capable of emitting light rays; a reflection surface (102.2) intended to be coated with a varnish and configured to reflect the light rays so as to form a light beam with an upper cut-off, said reflection surface comprising a first zone (102.2.4, 102.2.6) extending longitudinally and configured to form an upper cutoff light image and a second region (102.2.3, 102.2.5) and a third region (102.2.5, 102.2.7) extending longitudinally along the first region (102.2.4, 102.2.6), respectively on either side of said first zone, where the reflection surface (102.2) has a transverse profile forming a downward step from the first zone (102.2.4, 102.2.6 ) to each of the second (102.2.3, 102.2.5) and third (102.2.5, 102.2.7) zones.
