Light-emitting apparatus, illumination system, vehicle headlamp, projector, and method for manufacturing light-emitting apparatus

摘要

A headlamp (1) includes a semiconductor laser (3); a light-emitting element (7) that emits light in response to laser light emitted from the semiconductor laser (3); a heat-conducting member (13) that receives heat generated by the light-emitting element (7) through a light-emitting-element facing surface (13a); and a gap layer (15) that is disposed between the light-emitting element (7) and the light-emitting-element facing surface (13a) and that conducts the heat generated by the light-emitting element (7) to the light-emitting-element facing surface (13a). The gap layer (15) contains at least an inorganic amorphous material.

1. A light-emitting apparatus comprising:
an excitation light source that emits excitation light; a light emitter that emits light in response to the excitation light emitted from the excitation light source; a heat-conducting member that has a light-emitter facing surface facing the light emitter and that receives heat generated by the light emitter through the light-emitter facing surface; and a gap layer that is disposed between the light emitter and the light-emitter facing surface and that conducts the heat generated by the light emitter to the light-emitter facing surface, wherein the gap layer contains at least an inorganic amorphous material, and the heat-conducting member is transparent and placed in the light emitting apparatus so that the excitation light passes through the heat-conducting member and the gap layer in this order so as to reach the light emitter.
