Abstract

MODULE D’ECLAIRAGE AUTOMOBILE MATRICIEL ETENDU L’invention a pour objet un module d’éclairage (3) pour véhicule automobile, comprenant plusieurs sources lumineuses (6) ; un collecteur (4) avec plusieurs surfaces réfléchissantes (4.2) disposées côte-à-côte et configurées pour réfléchir une majorité des rayons lumineux émis par les plusieurs sources lumineuses (6), respectivement, en des faisceaux lumineux côte-à-côte, dits réfléchis ; un dispositif optique de projection (12) des faisceaux lumineux réfléchis en faisceaux lumineux côte-à-côte, dits projetés ; un écran (20) disposé entre le collecteur (4) et le dispositif optique de projection (12), de manière à bloquer une partie latérale d’au moins un des faisceaux réfléchis ; et un moteur lumineux (22) disposé à l’avant de l’écran (20) et configuré pour former un faisceau lumineux complémentaire projeté par le dispositif optique de projection en un faisceau complémentaire projeté latéral aux faisceaux lumineux projetés. (Figure à publier avec l'abrégé : Figure 3)EXTENDED MATRIX AUTOMOTIVE LIGHTING MODULE The subject of the invention is a lighting module (3) for a motor vehicle, comprising several light sources (6); a collector (4) with several reflecting surfaces (4.2) arranged side-by-side and configured to reflect a majority of the light rays emitted by the several light sources (6), respectively, into side-by-side light beams, called think; an optical device for projecting (12) the light beams reflected into side-by-side light beams, called projected; a screen (20) arranged between the collector (4) and the optical projection device (12), so as to block a lateral part of at least one of the reflected beams; and a light engine (22) disposed in front of the screen (20) and configured to form a complementary light beam projected by the optical projection device into a complementary beam projected lateral to the projected light beams. (Figure to be published with the abstract: Figure 3)
