<P>PROBLEM TO BE SOLVED: To attain improvement in utilization efficiency of light and improvement in uniformity of luminance. <P>SOLUTION: The lighting fixture for vehicle has a first light source 14, a second light source 15, a first light guide body 6 having an incident face 8a into which light emitted from the first light source enters, and a second light guide body 7 having an incident face 11a into which light emitted from the second light source enters. A first operating surface 10a which internally reflects at least a part of light incident from the first light source is formed in the first light guide body and a second operating surface 13a which internally reflects at least a part of light incident from the second light source is formed in the second light guide body, the first light guide body and the second light guide body are arranged in a condition in which the first operating surface and the second operating surface are adjoined. A part of light which is emitted from the first light source and reached the first operating surface enters into the second light guide body from the second operating surface, and a part of light which is emitted from the second light source and has reached the second operating surface enters into the first light guide body from the first operating surface. <P>COPYRIGHT: (C)2012,JPO&INPIT |
