<P>PROBLEM TO BE SOLVED: To mutually and precisely align optical axes of a plurality of optical units each having a semiconductor light-emitting element as a light source. <P>SOLUTION: A lighting fixture unit 18 is equipped with a support member 30 to support a first semiconductor light-emitting element 40 and a second semiconductor light-emitting element 42, a first reflector 36 to reflect light emitted from the semiconductor light-emitting element 40 ahead, a horizontal face 34b to shield one part of reflected light from the first reflector 36, a projector lens 32 which is installed ahead of the first reflector 36 by pinching the horizontal face 34b and forms a light distribution pattern having a cut-off line by the light reflected by the first reflector 36, a positioning part to position the projector lens 32, and a second reflector 52 set below the second semiconductor light-emitting element 42 to reflect ahead the light emitted from the second semiconductor light-emitting element 42. In the lighting fixture unit, the horizontal face 34b, the positioning part, and the second reflector 52 are integrally molded as a composite part 34. <P>COPYRIGHT: (C)2011,JPO&INPIT |
