Abstract

L'invention concerne un dispositif d'éclairage, en particulier un dispositif d'éclairage à DEL. Dans un mode de réalisation de l'invention, le dispositif d'éclairage à DEL comprend une unité corps formant le corps dudit dispositif d'éclairage, dans laquelle est ouvert un côté d'une partie centrale; un module à DEL connecté à l'unité corps et déconnecté de celle-ci, correspondant à la forme de l'unité corps et comprenant une DEL émettant de la lumière; une feuille optique placée dans une partie avant de la DEL et irradiant la lumière émise par la DEL vers le côté ouvert de l'unité corps. Selon l'invention, plusieurs modules à DEL peuvent être connectés au dispositif d'éclairage et déconnectés de celui-ci à un moindre coût.
