<P>PROBLEM TO BE SOLVED: To provide an LED light source device with a simple structure, and with a small/light-weight and resin-made optical member free from being melted or deformed by heat. <P>SOLUTION: The LED light source device 10 is provided with an LED light source 11 comprising at least one LED, a resin-made optical member 12 controlling light distribution of light from each LED of the LED light source, and a heat sink 15 for radiating heat from the LED light source. The optical member 12 is coupled with and supported by the LED light source or the heat sink. The LED light source device 10 is structured so that a part 16 with high thermal resistance intervenes between the optical member and the LED light source or the heat sink. <P>COPYRIGHT: (C)2010,JPO&INPIT |
