<P>PROBLEM TO BE SOLVED: To provide a reflector which can surely reflect a light radiated from a lamp in a desired direction without suffering distortion on a reflection surface by limiting a distance between a projection part and a back side end of the reflection surface of the reflector. <P>SOLUTION: The reflector almost in a shape of a bowl comprises the reflection surface for reflecting the light radiated from the lamp, a neck on which the lamp is mounted; and openings formed on the front side and the back side, wherein an annular projection is formed in an area more than 2.5 mm apart from the back side end of the reflection surface toward the back side of the reflector on the inside surface of the reflector. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
