Abstract

L'invention concerne un luminaire (1) comprenant un réflecteur (3) définissant une cavité concave allongée dans laquelle se trouve une source lumineuse allongée (2), par exemple un tube fluorescent, en relation espacée avec le réflecteur, ce dernier entourant la source lumineuse sur sa face arrière, afin de réfléchir la lumière provenant de la source et de la faire émettre à partir de la cavité dans une direction dirigée de manière générale vers l'avant. Pour parvenir à une diffusion de la lumière à partir du luminaire (1) à personnaliser afin de satisfaire aux exigences de la situation dans laquelle ledit luminaire doit s'utiliser, le réflecteur (3) comporte, sur des faces opposées de la cavité, une structure prismatique (6) respective, faisant saillie de sa surface intérieure afin d'intercepter et de dévier la lumière émise, de manière générale dans une direction allant vers l'avant, depuis l'espace situé dans la cavité entre la source lumineuse (2) et le réflecteur (3).
