Abstract

Unité d’éclairage et dispositif d’éclairage L’invention concerne une unité d’éclairage (100) pour un dispositif d’éclairage médical (150) comportant un nombre de groupes de DEL (110, 110‘, 110‘‘), ce nombre de groupes de DEL étant connecté à une carte de circuits imprimés (115) plane commune, une optique (122, 122‘) environnante respective étant associée à chaque DEL (112, 112‘) d’au moins un groupe (110, 110‘) de ce nombre de groupes, par lesquelles une paire DEL-optique (120, 120‘) respective est formée. Selon l’invention, l’optique respective, en raison de sa structure, prédéfinit un angle d’inclinaison d’un axe de faisceau lumineux central d’un faisceau lumineux émis de la paire DEL-optique dans une direction d’inclinaison de la paire DEL-optique respective, l’angle d’inclinaison de l’optique respective étant fixé de telle sorte que les axes de faisceau lumineux respectifs des faisceaux lumineux émis des paires DEL-optique de l’au moins un groupe de DEL soient au moins partiellement gauches par paires les uns par rapport aux autres.
