Abstract

L'invention concerne un module optique comprenant une source de lumière à DEL (1), et une lentille (2). Une lumière de la source de lumière à DEL (1) sort par la lentille (2). Le module optique comprend également un composant d'abat-jour (3), qui atténue partiellement la lumière projetée par la source de lumière à DEL (1) vers les bords d'une surface d'incidence de lumière de la lentille (2). Les bords des taches de lumière du module optique sont nets. L'invention concerne également un éclairage comprenant le module optique.
