Title (EN) ILLUMINATION DEVICE
(FR) DISPOSITIF D'ÉCLAIRAGE
(JA) 照明装置
Abstract:
(EN) [Problem] The present invention addresses the problem of providing a high-durability illumination device in which a wavelength conversion sheet is used, the illumination device being used in a liquid crystal display or the like. The problem is solved by: the illumination device having a point-light source, a wavelength conversion sheet, and a light-amount-reducing member positioned between the point-light source and a wavelength conversion layer; the light-amount reducing member reducing the peak luminance of light irradiated from the point-light source by 10-80% over the light incidence surface of the wavelength conversion sheet, and setting the absorption rate of light having a wavelength of 450 mm measured using an integrating sphere to be 5% or less.
(FR) Le problème décrit par la présente invention est de concevoir un dispositif d'éclairage à durabilité élevée dans lequel est utilisée une feuille de conversion de longueur d'onde, le dispositif d'éclairage étant utilisé dans un dispositif d'affichage à cristaux liquides, ou analogue. La solution selon l'invention porte sur : un dispositif d'éclairage comportant une source de lumière ponctuelle, une feuille de conversion de longueur d'onde, et un élément de réduction de quantité de lumière disposé entre la source de lumière ponctuelle et une couche de conversion de longueur d'onde ; l'élément de réduction de quantité de lumière réduisant de 10 à 80 % la luminance de crête de la lumière émise par la source de lumière ponctuelle sur la surface d'incidence de lumière de la feuille de conversion de longueur d'onde, et fixant à une valeur inférieure ou égale à 5 % le taux d'absorption de lumière ayant une longueur d'onde de 450 nm mesuré à l'aide d'une sphère d'intégration.
(JA) 【課題】 液晶ディスプレイ等に用いられる、波長変換シートを利用する照明装置であって、耐久性が良好な照明装置の提供を課題とする。点光源と、波長変換シートと、点光源と波長変換層との間に配置される光量低減部材とを有し、光量低減部材は、波長変換シートの光入射面における、点光源が照射する光のピーク照度を10~80%低減するものであり、かつ、積分球を用いて測定される波長450nmの光の吸収率が5%未満であることにより、課題を解決する。
