Abstract

MODULE D’ECLAIRAGE BI-LED AVEC PIECE OPTIQUE TRANSPARENTE MINCE L’invention a trait à une unité lumineuse (4, 6) comprenant une source lumineuse (12, 18) apte à émettre des rayons lumineux suivant un faisceau lumineux central et un faisceau lumineux extérieur annulaire ; un dispositif optique (14, 20) comprenant une partie centrale (14.1, 20.1) apte à transmettre le faisceau lumineux central suivant un axe optique (16, 22) de l’unité lumineuse, et une partie extérieure (14.2, 20.2) apte à réfléchir le faisceau lumineux extérieur annulaire suivant ledit axe optique (16, 22); dans lequel la partie extérieure (14.2, 20.2) forme une paroi annulaire assurant la réflexion du faisceau lumineux extérieur annulaire. L’invention a trait également à un module d’éclairage (2) comprenant deux unités lumineuses (4, 6) suivant l’invention, disposées de part et d’autre d’un axe optique (8) et comprenant une lentille de projection commune.
