Abstract

La présente invention concerne un module 1 d'éclairage pour projecteur de véhicule réalisant un faisceau d'éclairage du type à coupure particulièrement adapté à une utilisation avec des diodes électroluminescentes. Ce module 1 comporte un premier réflecteur 2 comportant une surface 7 sensiblement elliptique de réflexion des rayons lumineux et au moins une première source lumineuse 6 agencée au voisinage du premier foyer F1 dudit premier réflecteur 2. Le module 1 comporte en outre un deuxième réflecteur 3 produisant une première partie du faisceau à coupure et ayant un axe optique A1 passant par le second foyer F2 du premier réflecteur 2 et perpendiculaire à l'axe optique A1 dudit premier réflecteur 2, un troisième réflecteur 4 produisant une deuxième partie du faisceau à coupure et ayant un axe optique A1 passant par le second foyer F2 dudit premier réflecteur (2) et perpendiculaire à l'axe optique (A1) dudit premier réflecteur 2 et un quatrième réflecteur 5, dit plieuse, agencé entre ledit deuxième réflecteur 3 et ledit troisième réflecteur 4. La plieuse 5 comporte un bord 11, dit bord de coupure, agencé au voisinage dudit second foyer F2 dudit premier réflecteur 2 de manière à former la coupure dans le faisceau d'éclairage et une face supérieure réfléchissante 10 incluant lesdits axes optiques A1 respectifs desdits deuxième et troisième réflecteur 3 et 4.
