<P>PROBLEM TO BE SOLVED: To provide a heat radiation structure of an LED lamp which prevents heat energy generated at a lamp light source from concentrating and remaining in the lamp light source, conducts the heat energy to a heat radiation member and thermally-conductive member connected to a light emission member, and rapidly radiates heat from a heat radiation sheet of a lamp casing. <P>SOLUTION: The heat radiation structure includes at least the lamp casing and the lamp light source. The lamp casing mainly includes a casing having a hole and the heat radiation sheet. The hole is formed at the casing, and many heat radiation sheets are arranged so as to surround the casing. The lamp light source mainly includes a light emission member, the heat radiation member, the thermally-conductive member, and an outer cover, and is arranged in the hole of the lamp casing. The heat radiation member is connected to a rear side of the light emission member, and furthermore, the thermally-conductive member is connected to an end of the heat radiation member. Thereby, the light emission member is inserted and fitted to an open hole port of the lamp casing, and the heat energy generated by the light source generated by the light emission member is conducted to the thermally-conductive member through the heat radiation member. The heat energy is further conducted to the casing of the lamp casing and the heat radiation sheet by the thermally-conductive member to dissipate heat. <P>COPYRIGHT: (C)2011,JPO&INPIT |
