Zusammenfassung: | PROBLEM TO BE SOLVED: To solve the problem of a conventional vehicular lighting fixture in that part of light from a light source is not effectively utilized. SOLUTION: A lens 3 comprises: a direct-incident-light controlling section 6 for controlling direct incident light L1 that is directly incident from the light source 2 and emitting the same parallel to an optical axis Z-Z; and a reflection light controlling section 7 for controlling reflection light L4 that is incident after being reflected by a reflector 4 and emitting the same parallel to the optical axis Z-Z. As a result, out of the light L1 and the light L2 coming from the light source 2, the direct incident light L1 that is directly incident on the lens 3 is controlled by the direct-incident-light controlling section 6 to be emitted parallel to the optical axis Z-Z, and the reflection light L2 that is reflected by the reflector 4 and incident on the lens 3 is controlled by the reflection light controlling section 7 to be emitted parallel to the optical axis Z-Z. It is thus possible to effectively utilize most part of the light L1 and light L2 from the light source 2. COPYRIGHT: (C)2006,JPO&NCIPI |
