<P>PROBLEM TO BE SOLVED: To reduce hazardousness of a laser beam by emitting the laser beam converted into scattered light. <P>SOLUTION: The headlight 1 using the laser beam is equipped with a scattered light emission part 21 emitting scattered light by receiving the laser beam not in a predetermined passing route or an irradiation area of the laser beam. When the laser beam is out from the predetermined passing route or the irradiation area, the scattered light emission part emits scattered light in receipt of the laser beam. Thus, since the laser beam is converted into scattered light and to be emitted, hazardousness of the laser beam can be reduced. Since, further, the scattered light emission part is close to the predetermined passing route or irradiation area, the scattered light can be emitted even if the laser beam slightly comes off from the predetermined passing route or irradiation area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
