<P>PROBLEM TO BE SOLVED: To provide a light for vehicle causing almost no reduction of flux utilization factor regardless of miniaturization. <P>SOLUTION: The light for vehicle includes a central light source, first and second peripheral light sources disposed on both sides of the central light source, and a multi-light source control lens. The multi-light source control lens has a central incidence plane converting an irradiation light from the central light source to a collimated light, a central outgoing plane diffusing the irradiation light from the central incidence plane, a first peripheral incidence plane disposed on an optical axis of the first peripheral light source, a first total reflection plane converting the irradiation light incidence from the first peripheral light source through the first peripheral incidence plane to a collimated light and totally reflecting the light on a first peripheral outgoing plane, a second total reflection plane converting the irradiation light incident from the first peripheral light source through the first peripheral incidence plane into a collimated light and totally reflecting the light on a second peripheral outgoing plane, a third total reflection plane converting the irradiation light incident from the second peripheral light source through a second peripheral incidence plane and totally reflecting the light on the second peripheral outgoing plane, and a fourth total reflection plane converting the irradiation light incident from the second peripheral light source through the second peripheral incidence plane into a collimated light and totally reflecting the light on the first peripheral outgoing plane. <P>COPYRIGHT: (C)2010,JPO&INPIT |
