Claims (4)

励起光を出射するレーザ光源と、
上記レーザ光源から出射されたレーザ光を受けて蛍光を発する発光部と、
上記発光部が発生させた蛍光を、所定の投光方向に向けて投光する投光部とを備え、
上記発光部は、上記レーザ光源と離間して設置されており、
上記発光部は、当該発光部を支持する熱伝導性部材に当接させて配置されており、
上記発光部の側面に対向する位置に、上記蛍光を反射させる反射部材が配置されることを特徴とする発光装置。 A laser light source that emits excitation light;
A light emitting unit that emits fluorescence in response to laser light emitted from the laser light source;
A light projecting unit that projects the fluorescence generated by the light emitting unit toward a predetermined light projecting direction;
The light emitting unit is installed apart from the laser light source,
The light emitting portion is arranged to be abutted against the heat conductive member that supports the light emitting portion,
In a position facing the side surface of the light emitting portion, the light emitting device characterized by reflecting member for reflecting the fluorescence is disposed. 上記発光部の底面から上面へ向かう方向を上方としたとき、上記反射部材の反射面の上端は、上記発光部の上面よりも上方に位置することを特徴とする請求項１に記載の発光装置。   2. The light emitting device according to claim 1, wherein an upper end of a reflecting surface of the reflecting member is located above an upper surface of the light emitting unit when a direction from the bottom surface to the upper surface of the light emitting unit is set upward. . 上記発光部は、上記熱伝導性部材に形成された凹部の底部に配置されており、
上記凹部の側面が上記反射部材の反射面として機能することを特徴とする請求項１または２に記載の発光装置。 The light emitting part is disposed at the bottom of a recess formed in the thermally conductive member,
The light emitting device according to claim 1, wherein a side surface of the concave portion functions as a reflective surface of the reflective member. 上記発光部の底面から上面へ向かう方向を上方としたとき、上記反射部材の反射面は、上方に向かうにしたがって、対向する上記発光部の側面から離間するように傾斜していることを特徴とする請求項１から３までのいずれか一項に記載の発光装置。   When the direction from the bottom surface to the top surface of the light emitting unit is set to the upper side, the reflecting surface of the reflecting member is inclined so as to be separated from the side surface of the facing light emitting unit as it goes upward. The light-emitting device according to any one of claims 1 to 3.
