<P>PROBLEM TO BE SOLVED: To support continuously a light emitting part by a supporting member even if adhesion between the light emitting part and the supporting member is degraded by heat generated by the light emitting part in the case the light emitting part is supported by adhesion between the light emitting part and the supporting member. <P>SOLUTION: The headlight 1 is provided with a light emitting part 7 which emits light by excitation light emitted from a semiconductor laser 3 and irradiates illumination light, a supporting member 13 supporting the light emitting part 7 at a position where the excitation light is irradiated, a transparent plate 9 and a screw 14 which contact with at least a part of face of an external face of the light emitting part 7 and give a pressure between at least the part of face and the supporting member 13 and press the light emitting part 7 to the supporting member 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
