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). Figure 1Optical light emitting device (20), configured for the illumination of a scene (21) comprising N zones (26), said device (20) being characterized in that it comprises a source (22) of emission of light rays, a plurality of N optical deflectors (23) arranged in a pupil (24, 25) of the optical device (20), said optical deflectors (23) being configured to deflect the light rays coming from the source (22) light towards the zones (26) of the scene (21), an optical module (27), interposed between the source (22) and the optical deflectors (23), said module (27) being configured to transmit light rays emitted by the light source (22) only towards a subset of N1 optical deflectors (23), N1 being strictly less than N, for the illumination of a subset of the zones (26) of the scene (21).
