<P>PROBLEM TO BE SOLVED: To achieve down-sizing and simplification of a lighting fixture, when a projector type lighting fixture unit is adopted as the lamp unit of a vehicular head light, with a light-emitting element as the light source. <P>SOLUTION: In the projector type lighting fixture unit 30 with a first light emitting element 34 as the light source, in the vicinity of rear side focus face of a projector lens 32, five second light-emitting elements 44 to carry out light irradiation to the projector lens 32 are arranged. Then, basic light distribution pattern is formed by lighting the first light-emitting element 34, an additional light distribution pattern is added and formed to the basic light distribution pattern by adding and lighting the five second light-emitting elements 44, thereby the light distribution pattern formed by the irradiation light from the lighting fixture unit 30 is made fully bright. <P>COPYRIGHT: (C)2007,JPO&INPIT |
