Abstract

L'invention concerne un projecteur de lumière et son procédé de commande. Ce projecteur de lumière comprend une première unité source de lumière qui comporte une première source de lumière conçue pour émettre un premier faisceau lumineux, et un premier réflecteur conçu pour réfléchir le premier faisceau lumineux; et une deuxième unité source de lumière qui comporte une deuxième source de lumière conçue pour émettre un deuxième faisceau lumineux présentant une température de couleur différente de celle du premier faisceau lumineux, et un deuxième réflecteur conçu pour réfléchir le deuxième faisceau lumineux. Ledit projecteur de lumière irradie les faisceaux lumineux sur un objet au moyen d'un procédé de mélange d'au moins deux sources de lumière et d'un procédé de commande de gradation, ce qui permet d'obtenir librement divers faisceaux lumineux présentant différents éclairages et températures de couleur les uns par rapport aux autres, et d'ajuster la quantité de faisceaux lumineux afin d'irradier une quantité nécessaire de lumière sur l'objet. Ainsi, le projecteur de lumière peut produire un effet d'éclairage intense et avoir un effet d'économie d'énergie.
