Abstract

Dispositif d'éclairage pour la production de lumière à caractéristiques de rayonnement différentes, qui comporte une source de lumière d'excitation destinée à émettre une lumière d'excitation bleue, un élément de formations de faisceau et un convertisseur pour convertir une partie de la lumière d'excitation. Le convertisseur est situé dans la trajectoire du faisceau de la source de lumière d'excitation et sert à convertir une partie de la lumière d'excitation en lumière à longueur d'onde plus longue et à réfléchir une autre partie de la lumière d'excitation. La superposition de la lumière convertie et de la lumière d'excitation émise par le convertisseur permet d'obtenir dans la zone proche une impression de couleur souhaitée prédéfinie, tandis que la lumière émise, dans sa totalité, paraît dans la zone lointaine uniformément blanche.
