Abstract

Unité de lampe Une unité de lampe comprend un dispositif réfléchissant (12) dans lequel un réseau de micro-miroirs est entraîné de manière sélective pour réfléchir de manière sélective de la lumière incidente, le réseau de micro-miroirs étant un réseau de micro-miroirs disposés dans une matrice ; une lentille de projection qui projette vers l’avant dans une configuration de distribution de lumière la lumière réfléchie de manière sélective par le dispositif réfléchissant (12) ; et une partie de prévention configurée pour empêcher de la lumière externe incidente sur la lentille de projection d’être condensée dans une zone autre que le réseau de micro-miroirs pour empêcher une augmentation de température de la zone. Figure pour l’abrégé : Fig. 4.
