<P>PROBLEM TO BE SOLVED: To provide an LED light source which eliminates faults of the conventional art, and to improve the value and the fascination of the LED light source. <P>SOLUTION: A hole 14 is formed at the base of a reflection body, and a stem 16 having heat conduction is fitted into the hole 14. The stem 16 has a first surface 18 inside the reflection body and a second surface 20 outside the reflection body. A single-side emission LED light source 22 is fixed to the first surface 18 preferably via a member 23 for electric insulation but having heat conduction. A heatsink 24 is fixed to the second surface 20.A circuit 26 capable of being mounted on a printed circuit board is connected to the LED light source to supply an electric power to the LED light source. A preferable electric connection to the LED light source 22 not shown in Figure is prepared through insulated wires which pass the side of the stem 16 or penetrate a lengthwise direction hole formed in the stem 16. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
