Abstract

MODULE LUMINEUX IMAGEANT LA SURFACE ÉCLAIRÉE D’UN COLLECTEUR AVEC BLOQUEUR DE RAYONS PARASITES EXTRUDÉ L’invention a trait à un module lumineux (2) comprenant une source lumineuse (4) apte à émettre des rayons lumineux ; une platine (6) supportant la source lumineuse (4) ; un collecteur (8) avec une surface réfléchissante (8.2) configurée pour collecter et réfléchir les rayons lumineux en un faisceau lumineux réfléchi suivant un axe optique (10) ; un système optique (12) configuré pour projeter le faisceau lumineux réfléchi en imageant une partie de la surface réfléchissante (8.2) ; un écran (14) situé à l’avant de la source lumineuse (4), suivant une direction principale de propagation du faisceau lumineux réfléchi, et configuré pour récolter des rayons lumineux provenant directement de la source, dit rayons directs (16) ; dans lequel l’écran (14) s’étend suivant une direction transversale (14.1) avec une section constante et est disposé sur la platine (6). (Figure à publier avec l'abrégé : Figure 1)
