<P>PROBLEM TO BE SOLVED: To solve a problem of freezing of an LED lamp having proper properties as a vehicle. <P>SOLUTION: A carbonaceous heating element 16 is arranged in a lamp housing 12 housing LEDs 14, and a reflection plate 18 is arranged so that the heat rays emitted from the carbonaceous heating element 16 are irradiated on a front panel 10. The front panel 10 frozen is thawed, by utilizing the carbonaceous heating element having properties of small rush current, quick rise in the temperature, and high far-infrared-ray emission efficiency. <P>COPYRIGHT: (C)2010,JPO&INPIT |
