<P>PROBLEM TO BE SOLVED: To solve the following problem with an LED light source headlight: use of only one light source is insufficient in light quantity; and use of a plurality of light sources needs to isolate the light sources for a reason of heat generation and leads to a gap unable to emit light, thereby the gap making it impossible to observe the light sources as one lamp device. <P>SOLUTION: A required number of LED light sources mounted with a reflective surface for each LED light source are arranged in parallel at a required interval, while the interval portion is covered with an extension whose surface is subjected to bright treatment, and the extension is exposed for brightness to light from a lambertian distribution L that is a part of light from the LED light source, which does not reach the reflective surface, so as to make a plurality of reflective surfaces to be visible integrally. <P>COPYRIGHT: (C)2010,JPO&INPIT |
