Abstract

Dispositif (20) optique d’émission de lumière, configuré pour l’illumination d’une scène (21) comprenant N zones (26), ledit dispositif (20) étant caractérisé en ce qu’il comprend une source (22) d’émission de rayons lumineux, une pluralité de N déflecteurs (23) optiques disposés dans une pupille (24, 25) du dispositif (20) optique, lesdits déflecteurs (23) optiques étant configurés pour dévier les rayons lumineux provenant de la source (22) lumineuse vers les zones (26) de la scène (21), un module (27) optique, interposé entre la source (22) et les déflecteurs (23) optiques, ledit module (27) étant configuré pour transmettre des rayons lumineux émis par la source (22) lumineuse uniquement vers un sous-ensemble de N1 déflecteurs (23) optiques, N1 étant strictement inférieur à N, pour l’illumination d’un sous-ensemble des zones (26) de la scène (21).
