<P>PROBLEM TO BE SOLVED: To provide a light-emitting diode fixing structure for a lighting device capable of suitably fixing a light-emitting diode on a heat sink. <P>SOLUTION: Both back surfaces 2b, 3b are in the approximately flush state while the light-emitting diode 2 is fitted into a recessed section 11 of a holder 3. Therefore, when the holder 3 is fixed on the surface 4a of the heat sink 4 via a fixing means while the light-emitting diode 2 is fitted into the recessed section 11 of the holder 3, the back surface 2b of the light-emitting diode 2 is firmly stuck on the surface 4a of the heat sink 4. Thus, the light-emitting diode 2 is fixed at a regular posture, and accordingly, an optical axis S is never to be inclined. A relative angle relationship to a reflector 5 and a projector lens 7 is retained at a fixed state, and optical performance of a lamp tool unit 1 is guaranteed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
