Abstract

La présente invention concerne un dispositif d'éclairage comprenant : au moins deux sources de lumière laser (6) destinées à émettre de la lumière de différentes longueurs d'onde; un dispositif de balayage (8) destiné à imprimer un mouvement de balayage à un faisceau laser émis par la ou les sources de lumière laser (6) sur une surface de diffusion (10); un pilote (3) conçu pour commander la modulation de la ou des sources de lumière laser (6) et/ou le fonctionnement du dispositif de balayage (8) de sorte que de la lumière émise forme un motif lumineux souhaité; et une alimentation électrique (4) conçue pour fournir de l'énergie électrique aux sources de lumières laser (6) de sorte que la puissance de sortie spectrale moyenne du dispositif d'éclairage pendant un intervalle de temps donné est sensiblement constante. Selon l'invention, la puissance de sortie spectrale moyenne pendant un intervalle de temps donné est maintenue sensiblement constante. Cela permet l'obtention de motifs de balayage variables représentés sous forme d'image par le système de projection laser, alors que la sortie de lumière spectrale du système, et ainsi la sortie de lumière du dispositif qui est utilisé pour éclairer la pièce, reste constante.
