Abstract

La présente invention concerne un dispositif d'éclairage à LED comprenant : une partie de diffusion qui a la forme d'une boîte possédant une surface supérieure ouverte et qui comporte un trou traversant au centre de sa surface inférieure ; une partie de fixation de substrat qui fixe un substrat, sur lequel une LED est montée, du côté inférieur du trou traversant de la partie de diffusion dans un état où le substrat est introduit dans le trou traversant ; et une partie de réflexion qui comporte une surface inférieure dont le centre est mis en contact avec la partie centrale du substrat, cette partie de réflexion créant une surface de réflexion dotée d'une surface incurvée de sorte que l'espace qu'elle forme avec la partie de diffusion augmente vers son bord. Cette invention éclaire un plafond tout entier avec une distribution uniforme de la lumière puisqu'elle est installée au centre de ce plafond, elle peut ainsi empêcher l'apparition d'un phénomène d'éblouissement et elle permet d'utiliser un éclairage indirect en tant qu'éclairage principal.
