<P>PROBLEM TO BE SOLVED: To provide a lighting fixture equipped with a small light guide lens having good optical performance. <P>SOLUTION: This lighting fixture includes a first light entering surface 2 and a second light entering surface 3 on the side covering the light source 7 of a light guide lens 1, and also equipped with a first light reflecting surface 4, a first light emitting surface 5, and a second light emitting surface 6 on the opposite side. Rays L1 of light emitted from the light source 7 located at a first focus P1 are emitted to the outside through the first reflecting surface 4, a second focus P2, and the first light emitting source 5, and rays L2 of light are emitted to the outside through the second light entering surface 3 and the second light emitting surface 6. At this time, the rays L1 and the rays L2 both form almost mutually parallel light and are radially emitted from the light guide lens 1 with the optical axis as a center axis. <P>COPYRIGHT: (C)2010,JPO&INPIT |
