Abstract
(EN) An LED assembly includes an LED light source having a first light output with a characteristic spectrum, and a yellow-green phosphor, red phosphor, and neodymium fluorine absorber combination through which the first light output passes, wherein the yellow-green phosphor, red phosphor, and neodymium fluorine absorber combination is configured to convert the first light output to a second light output having a predetermined correlated color temperature.
(FR) L'invention concerne un ensemble DEL comprenant une source de lumière à DEL ayant une première sortie de lumière comportant un spectre caractéristique et comprenant une combinaison d'un luminophore jaune-vert, d'un luminophore rouge et d'un absorbeur de fluor néodyme, la première sortie de lumière passsnt par ladite combinaison. La combinaison du phosphore jaune-vert, du phosphore rouge et de l'absorbeur de fluor néodyme est conçue pour convertir la première sortie de lumière en une seconde sortie de lumière ayant une température de couleur corrélée prédéfinie.
