<P>PROBLEM TO BE SOLVED: To solve the following problem: in a conventional vehicular lighting fixture, only two lamp functions can be obtained by one lamp unit, and a light distribution pattern having cutoff lines such as a low beam light distribution pattern cannot be obtained. <P>SOLUTION: The vehicular lighting fixture includes a reflector 2, a light source 3, a movable shade 29, a switching device 30, and a projection lens 5. The reflector 2 has an elliptical reflecting surface 8. The light source 3 has a first light-emitting member 11, a second light-emitting member 12, and a light-shielding member 10. The movable shade 29 moves between a first position and a second position by the switching device 30. As a result, the vehicular lighting fixture has: a first lamp function by which a low beam light distribution pattern having cutoff lines CL1, CL2, CL3; a second lamp function by which a high beam light distribution pattern HP can be obtained; and a third lamp function by which a daytime light distribution pattern DP can be obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT |
