Abstract
The present invention provides a radiator for a light emitting unit, annexed to the light emitting unit including a multiplicity of light emitting diodes mounted on substantially the same axis line on a first principal surface of a wiring substrate. The radiator includes a radiating plate and a heat pipe. The radiating plate is combined with the wiring substrate, with a first principal surface faced as a faying surface to a second principal surface opposite to the first principal surface of the wiring substrate, and is provided with a heat pipe fitting portion. The heat pipe is mounted into the heat pipe fitting portion of the radiating plate while keeping close contact with the inner wall of the heat pipe fitting portion. The heat generated from the light emitting diode group is transferred to a radiating means through the radiating plate and the heat pipe.
