Title (EN) COLOR CONVERSION ELEMENT AND LIGHTING DEVICE
(FR) ÉLÉMENT DE CONVERSION DE COULEUR ET DISPOSITIF D’ÉCLAIRAGE
(JA) 色変換素子及び照明装置
Abstract:
(EN) This color conversion element (4) is provided with: a phosphor layer (44) including phosphors (441) of at least one type; a reflection layer (43) laminated on the phosphor layer (44); a substrate (41) disposed facing the reflection layer (43); a bonding part (42) interposed between the reflection layer (43) and the substrate (41) to bond the reflection layer (43) and the substrate (41); and an absorbing part (45) that is covered by the bonding part (42) on a principal surface (411) of the substrate (41) on the bonding part (42) side, and that absorbs laser light having a wavelength which excites the phosphors (441).
(FR) Cet élément de conversion de couleur (4) est pourvu de : une couche de luminophore (44) comprenant des luminophores (441) d’au moins un type ; une couche de réflexion (43) stratifiée sur la couche de luminophore (44) ; un substrat (41) disposé face à la couche de réflexion (43) ; une partie de liaison (42) intercalée entre la couche de réflexion (43) et le substrat (41) pour relier la couche de réflexion (43) et le substrat (41) ; et une partie d’absorption (45) qui est recouverte par la partie de liaison (42) sur une surface principale (411) du substrat (41) sur le côté de partie de liaison (42), et qui absorbe une lumière laser ayant une longueur d’onde qui excite les luminophores (441).
(JA) 色変換素子(4)は、少なくとも一種類の蛍光体(441)を含む蛍光体層(44)と、蛍光体層(44)に積層された反射層(43)と、反射層(43)に対向配置された基板(41)と、反射層(43)と基板(41)との間に介在して反射層(43)と基板(41)とを接合するための接合部(42)と、基板(41)における接合部(42)側の主面(411)上で接合部(42)に覆われ、蛍光体(441)を励起させる波長のレーザー光を吸収する吸収部(45)とを備える。
