Document Type and Number:
WIPO Patent Application WO/2012/121343
Kind Code:
A1
Abstract:
A headlamp (1) is provided with: a semiconductor laser (3); a light-emitting unit (7) for emitting laser light output from the semiconductor laser (3); a heat conduction member (13) which receives heat from the light-emitting unit (7) through a surface (13a) opposite the light-emitting unit; and a spacing layer (15) which is provided between the light-emitting unit (7) and the surface (13a) opposite the light-emitting unit, and transmits the heat from the light-emitting unit (7) to the surface (13a) opposite the light-emitting unit. The spacing layer (15) includes at least an inorganic amorphous material.
