Abstract

L'invention porte sur un luminaire servant à distribuer la lumière émise par une source (7) de lumière. Ce luminaire comprend un ou plusieurs réflecteurs (2, 3) qui sont placés de manière symétrique autour de l'ampoule (7) pour renvoyer et réfléchir la lumière émise par l'ampoule (7). Au moins un dispositif (4, 5) propageant la lumière est prévu autour des réflecteurs (2, 3) pour recevoir la lumière réfléchie par les réflecteurs (2, 3). Un tel luminaire assure une distribution uniforme de la lumière tout en réduisant au maximum l'éblouissement produit par le dispositif d'éclairage.
