<P>PROBLEM TO BE SOLVED: To provide a thin, new and attractive vehicular reflection type lighting fixture unit having high utilization efficiency of light emitted from a semiconductor light source such as an LED. <P>SOLUTION: This vehicular reflection type lighting fixture unit mounted to a vehicle to form a prescribed light distribution pattern is equipped with the semiconductor light source disposed by turning a light emitting surface upward or downward when viewing the lighting fixture from the front, a twice-reflecting optical system twice reflecting rays of light going toward either one side of the right and left of the semiconductor light source when viewing the lighting fixture from the front mainly, among rays of light irradiated toward the front of the light emitting surface from the semiconductor light source, to form a first light distribution pattern which is a part of the prescribed light distribution pattern, and an once-reflecting optical system once reflecting a ray of light going toward the other side opposite to the above one side of the semiconductor light source mainly, among rays of light irradiated toward the front of the light emitting surface from the semiconductor light source, to form a second light distribution pattern which is a part of the prescribed light distribution pattern. <P>COPYRIGHT: (C)2010,JPO&INPIT |
