Abstract:
A light source unit is provided with a substrate and segments of a reflector. The substrate has a plurality of light-emitting devices mounted on its central and peripheral portions. The segments correspond to the light-emitting devices, individually. The segment corresponding to the light-emitting devices mounted on the central portion are higher in thermal radiation capacity than the segment corresponding to the light-emitting devices mounted on the peripheral portion.
