The invention relates to a light illumination apparatus comprising at least one exposure head (12) and at least two light modulating arrangements (20), each of said two light modulating arrangements (20) comprising a spatial light modulator (31, 32) and an associated light emitter arranged for illumination of an illumination surface (15) via said spatial light modulator (31, 32), each of said two light modulating arrangements (20) being digitally controlled, said apparatus comprising means for performing a relative movement between said at least one exposure head and said illumination surface (15) in at least one direction (x;y).
L'invention concerne un dispositif d'éclairage lumineux comportant au moins une tête d'exposition (12) et au moins deux systèmes de modulation de la lumière (20). Chacun des deux systèmes de modulation de la lumière (20) comporte un modulateur de lumière spatial (31, 32) et un émetteur de lumière associé, conçu pour éclairer une surface d'éclairage (15) par l'intermédiaire dudit modulateur de lumière spatial (31, 32), lesdits systèmes de modulation de la lumière (20) étant par ailleurs commandés de façon numérique. Le dispositif selon l'invention comporte également des éléments destinés à créer un mouvement relatif entre la ou les têtes d'exposition et ladite surface d'éclairage (15) dans au moins une direction (x, y).
