Abstract

L'invention concerne un dispositif d'émission de lumière (1) qui est conçu pour être fixé à un élément de support s'étendant dans un premier plan, par exemple un plafond de local (102), et pour éclairer une surface (110) qui se trouve dans un deuxième plan s'étendant sensiblement perpendiculairement au premier plan. Il présente une première source lumineuse (10) qui émet de la lumière dans une direction opposée à la surface (110) à éclairer ainsi qu'un réflecteur (20) qui est disposé et conçu de manière que les rayons lumineux incidents en provenance de la source lumineuse (10) soient réfléchis de manière sensiblement uniforme sur la surface (110) à éclairer.
