Abstract

L'invention concerne des dispositifs 1, 11 à réglage variable de la teinte de lumière ainsi que des procédés pour régler la teinte de lumière d'un dispositif d'éclairage 1, 11. Selon un premier concept de l'invention, la lumière émise par plusieurs sources lumineuses d'excitation 2, 3, 4 d'un dispositif d'éclairage 1 est au moins partiellement convertie en termes de longueurs d'onde par plusieurs moyens de conversion chromatique 6, 7, 8. Les moyens de conversion chromatique 6, 7, 8 sont accordés sur les longueurs d'ondes λ2, λ3, λ4 des sources lumineuses d'excitation 2, 3, 4. Selon un deuxième concept de l'invention, la lumière émise par une source lumineuse d'excitation 12 est convertie en termes de longueurs d'ondes au moins par un premier moyen de conversion chromatique 6 ou un deuxième moyen de conversion chromatique 7, les moyens de conversion chromatique 6, 7 étant interchangeables.
