Title
(EN) FLUORESCENT LIGHT SOURCE DEVICE
(FR) DISPOSITIF DE SOURCE DE LUMIÈRE FLUORESCENTE
(JA) 蛍光光源装置
Abstract
(EN) Provided is a fluorescent light source device with which, when excitation light is emitted to a wavelength conversion member, rearward scattering of the excitation light is controlled and fluorescence generated inside the wavelength conversion member can be emitted to the outside with high efficiency, and with which high light-emitting efficiency can be obtained. The fluorescent light source device comprises a wavelength conversion member which uses phosphors that are excited by excitation light, and is characterized in that the wavelength conversion member has formed on a front surface thereof serving as an excitation light receiving surface a front-surface-side periodic structure, has formed on a rear surface thereof a rear-surface-side periodic structure, and has a light reflecting surface disposed on the outside of the rear surface.
(FR) L'invention concerne un dispositif de source de lumière fluorescente avec lequel, lorsqu'une lumière d'excitation est émise vers un élément de conversion de longueur d'onde, une diffusion vers l'arrière de la lumière d'excitation est commandée et une fluorescence générée à l'intérieur de l'élément de conversion de longueur d'onde peut être émise vers l'extérieur avec une efficacité élevée, et avec lequel un rendement d'émission lumineuse élevé peut être obtenu. Le dispositif de source de lumière fluorescente comprend un élément de conversion de longueur d'onde qui utilise des luminophores qui sont excités par une lumière d'excitation, et caractérisé en ce que l'élément de conversion comprend une structure périodique côté surface avant servant de surface de réception de lumière d'excitation formée sur une surface avant de celui-ci, une structure périodique côté surface arrière formée sur une surface arrière de celui-ci, et une surface de réflexion de lumière disposée sur l'extérieur de la surface arrière.
(JA)  波長変換部材に励起光が照射されたときに、当該励起光の後方散乱が抑制されると共に、波長変換部材の内部において生じた蛍光を高い効率で外部に出射することができ、従って、高い発光効率が得られる蛍光光源装置を提供すること。 蛍光光源装置は、励起光により励起される蛍光体による波長変換部材を備えてなる蛍光光源装置であって、前記波長変換部材は、励起光受光面とされる表面に表面側周期構造が形成され、裏面に裏面側周期構造が形成されており、当該裏面の外側に光反射面が設けられていることを特徴とする。
