摘要	A headlamp includes: a laser diode for emitting laser beam; a light-emitting section for emitting light when irradiated with the laser beam emitted from the laser diode; and a cooling device for cooling the light-emitting device by use of a fluid. With the arrangement, it is possible to prevent an increase in temperature of the light-emitting section which is irradiated with excitation light, and thereby to realize a light source of long lifetime.
其他摘要	前照灯包括：用于发射激光束的激光二极管;用于从激光二极管发射的激光束照射时发光的发光部分;和冷却装置，用于通过使用流体冷却发光装置。利用该布置，可以防止被激发光照射的发光部分的温度升高，从而实现长寿命的光源。
主权项	A light-emitting device comprising: an excitation light source for emitting excitation light; a light-emitting section for emitting light in response to the excitation light; and a cooling section for cooling the light-emitting section with use of a fluid.
