Abstract

L'invention concerne un moteur lumière servant à produire et à reformater la sortie d'une source lumineuse. Le moteur lumière (1; 300; 400) comporte une source lumineuse (100), et un premier miroir (203; 303; 405) pour réfléchir la lumière provenant de la source lumineuse (100) en direction d'une cible (T). Le premier miroir (203; 303; 405) comporte un premier foyer (208). Un polariseur (204; 305; 406) est prévu entre le premier miroir (203; 303; 405) et le foyer (208). Le moteur lumière (1; 300) de l'invention comprend aussi au moins un deuxième miroir (203; 303) comportant un deuxième foyer (207).
