Title (EN) WAVELENGTH CONVERSION ELEMENT AND LIGHT EMITTING DEVICE
(FR) ÉLÉMENT DE CONVERSION DE LONGUEUR D'ONDE ET DISPOSITIF ÉLECTROLUMINESCENT
(JA) 波長変換素子及び発光装置
Abstract:
(EN) Provided is a wavelength conversion element (1) provided with: a support member (2) provided with a support surface (2a); and a wave conversion unit (4) disposed above the support surface (2a). The wave conversion unit (4) includes a plurality of first phosphor particles (4a) which absorb an excitation light (82) to generate fluorescence (second emitted light (91)), and a transparent bonding material (4b) for bonding the plurality of first phosphor particles (4a), and is provided with a joining surface (7) positioned on the support surface (2a) side and an incident surface (6) which faces the joining surface (7) and which the excitation light enters. The excitation light (82) and the fluorescence are emitted from the incident surface (6), the wavelength conversion unit (4) is provided with a plurality of protruding sections (5a), at least some of the plurality of protruding sections (5a) are disposed on the incident surface (6), and at the top of each of the plurality of protruding sections (5a), some of the plurality of first phosphor particles (4a) are exposed.
(FR) La présente invention a trait à un élément de conversion de longueur d'onde (1) qui comprend : un organe de support (2) pourvu d'une surface de support (2a) ; et une unité de conversion d'onde (4) disposée au-dessus de la surface de support (2a). L'unité de conversion d'onde (4) inclut une pluralité de premières particules de phosphore (4a) qui absorbent une lumière d'excitation (82) afin de générer de la fluorescence (seconde lumière émise (91)), et un matériau de liaison transparent (4b) qui sert à lier la pluralité de premières particules de phosphore (4a), et elle est dotée d'une surface de jonction (7) positionnée du côté de la surface de support (2a) et d'une surface d'incidence (6) qui fait face à la surface de jonction (7) et où la lumière d'excitation entre. La lumière d'excitation (82) et la fluorescence sont émises à partir de la surface d'incidence (6), l'unité de conversion de longueur d'onde (4) est pourvue d'une pluralité de sections saillantes (5a), au moins certaines sections de la pluralité de sections saillantes (5a) sont disposées sur ladite surface d'incidence (6), et, en haut de chaque section de cette pluralité de sections saillantes (5a), certaines particules de la pluralité de premières particules de phosphore (4a) sont visibles.
(JA) 支持面(2a)を備える支持部材(2)と、支持面(2a)の上方に配置された波長変換部(4)を備える波長変換素子(1)であって、波長変換部(4)は、励起光(82)を吸収して蛍光(第2の放射光(91))を発生する複数の第1の蛍光体粒子(4a)と、複数の第1の蛍光体粒子(4a)を結合する透明結合材(4b)とを含み、かつ、支持面(2a)側に位置する接合面(7)、及び、接合面(7)と対向し、励起光が入射される入射面(6)を備え、入射面(6)から、励起光(82)及び蛍光が出射され、波長変換部(4)は、複数の凸部(5a)を備え、複数の凸部(5a)の少なくとも一部は、入射面(6)に配置され、複数の凸部(5a)の各々の頂部には、複数の第1の蛍光体粒子(4a)のうちの一部が露出している。
