Abstract

Module d’éclairage route avec source lumineuse dirigée vers le haut L’invention a trait à un module d’éclairage (102) comprenant au moins une source lumineuse (104) apte à émettre des rayons lumineux vers le haut ; un collecteur (106) avec au moins une surface réfléchissante (106.1) configurée pour collecter et réfléchir les rayons lumineux émis par l’au moins une source lumineuse (104) en un faisceau lumineux réfléchi suivant l’axe optique (110) ; une lentille de projection (108) du faisceau lumineux réfléchi en un faisceau lumineux projeté ; où l’au moins une surface réfléchissante (106.1) est configurée pour que le faisceau lumineux réfléchi éclaire une face d’entrée (108.1) de ladite optique de projection (108) jusqu’à un bord supérieur (108.3) et/ou un bord inférieur (108.4) de ladite face d’entrée. (Figure à publier avec l'abrégé : Figure 3)Road lighting module with upwardly directed light source The invention relates to a lighting module (102) comprising at least one light source (104) capable of emitting light rays upwards; a collector (106) with at least one reflecting surface (106.1) configured to collect and reflect the light rays emitted by the at least one light source (104) into a reflected light beam along the optical axis (110); a projection lens (108) of the reflected light beam into a projected light beam; wherein the at least one reflecting surface (106.1) is configured so that the reflected light beam illuminates an entry face (108.1) of said projection optics (108) up to an upper edge (108.3) and/or a lower edge (108.4) of said entry face. (Figure to be published with the abstract: Figure 3)
