Abstract

L'invention concerne un dispositif d'éclairage de pièces conçu pour éclairer indirectement une surface utile et comportant tout d'abord un projecteur (2), dont le faisceau est orienté depuis l'horizontale vers le haut. Au-dessus du projecteur (2) se trouve une unité de déviation de la lumière (1) munie d'un réflecteur principal (11) en tant que diffuseur, servant à dévier vers le bas une première partie de la lumière émise par le projecteur (2) en direction de la surface utile et à faire passer une deuxième partie de la lumière émise par le projecteur (2) pour l'éclairage total de la pièce. Le projecteur (2) comprend au moins une DEL (23), de préférence plusieurs DEL (23), en amont desquelles est agencé respectivement un concentrateur (22) optique. L'unité de déviation de la lumière (1) comporte des réflecteurs supplémentaires (12, 13) agencés de manière adjacente sous le réflecteur principal (11). Le réflecteur principal (11) présente une surface orientée vers le bas courbée et une structure guidant la lumière (110), par exemple une structure de Fresnel. Les réflecteurs supplémentaires comprennent tout d'abord deux réflecteurs latéraux (12, 12) qui sont agencés en regard l'un de l'autre et de manière adjacente au réflecteur principal (11) et servent à empêcher l'éblouissement.
