PROBLEM TO BE SOLVED: To obtain a continuously changing light distribution pattern and to effectively use the light from a light source. SOLUTION: The light distribution patterns of sub-reflectors 2L and 2R are composed with the light distribution patterns of main reflectors 1L and 1R, and the composed light distribution pattern is changed continuously by making moving the sub-reflectors 2L and 2R move. Consequently, the continuously changing light distribution pattern can be obtained. The light from the light source 4 is made to reflect by the main reflectors 1L and 1R and the sub- reflectors 2L and 2R and radiated to the outside in a prescribed light distribution pattern. Consequently, the light from the light source 4 can be used effectively, as compared with a headlamp for reflecting the light from a light source with only by a reflector (main reflector). |
