<P>PROBLEM TO BE SOLVED: To allow a headlight for vehicle, which is configured so as to form a predetermined light distribution pattern, to control light intensity distribution of the light distribution pattern finely even if the headlight uses semiconductor light emitting elements as light sources. <P>SOLUTION: The headlight for vehicle comprises a plurality of lighting fixture units 20A, 20B, 20C, and 20D, which have light emitting diodes 32, 42, 52, and 62 as light sources respectively. The lighting fixture unit 20A and the lighting fixture units 20B, 20C, and 20D are used as a plurality of lighting fixture units, where the lighting fixture unit 20A have a light emitting diode 32, on which a single light emitting chip 32a is mounted, as a light source, and the lighting fixture units 20B, 20C, and 20D have light emitting diodes 42, 52, and 62, on which light emitting chips 42a, 52a, and 62a are mounted respectively, as light sources. Furthermore, a hot zone is formed by the radiation of the light from the lighting fixture unit 20A, and a diffusion region is formed by the radiation of the light from the lighting fixture units 20B, 20C, and 20D. <P>COPYRIGHT: (C)2004,JPO |
