摘要:
A headlamp 1 includes: a semiconductor laser 2, which emits laser light; and a light-emitting section 5, which includes at least either a fluorescent material sintered body obtained by sintering an oxynitride fluorescent material or a fluorescent material sintered body obtained by sintering an oxynitride fluorescent material and a nitride fluorescent material and which produces fluorescence upon receiving laser light emitted by the semiconductor laser 2. This allows the headlamp 1 to quickly radiate heat generated in the light-emitting section outward, thus bringing about an effect of preventing the light-emitting section from rising in temperature when irradiated with high-power and high-density laser light.
