Abstract
(EN) The present invention enables improvement of the luminous efficiency of a fluorescent layer. A wavelength conversion element which converts the wavelength range of incident light into a wavelength range that is different from the wavelength range of the incident light, and which comprises a fluorescent layer wherein first particles and second particles that are smaller than the first particles are dispersed in a first binder. This wavelength conversion element is configured such that: the first particles have fluorescence characteristics with respect to the wavelength of the incident light; and the ratio of the volume of the first binder to the volume of the particle group including the first particles and the second particles in the fluorescent layer is 10% or more but less than 50%.
(FR) La présente invention permet d'améliorer l'efficacité lumineuse d'une couche fluorescente. La présente invention concerne un élément de conversion de longueur d'onde qui convertit la plage de longueurs d'onde de la lumière incidente en une plage de longueurs d'onde qui est différente de la plage de longueurs d'onde de la lumière incidente, et qui comprend une couche fluorescente dans laquelle des premières particules et des deuxièmes particules qui sont plus petites que les premières particules sont dispersées dans un premier liant. Cet élément de conversion de longueur d'onde est conçu de telle sorte que : les premières particules ont des caractéristiques de fluorescence par rapport à la longueur d'onde de la lumière incidente ; et le rapport entre le volume du premier liant et le volume du groupe de particules comprenant les premières particules et les deuxièmes particules dans la couche fluorescente est égal ou supérieur à 10 %, mais inférieur à 50 %.
