VEHICULAR LIGHTING APPARATUS
First Claim
1. A vehicular lighting apparatus attachable to a front end part of a vehicle, comprising:
- a light guide element constructed by molding a translucent resin into a shape of a polyhedron having a pentahedron or more than the pentahedron;
a planar light-emitting unit that emits illumination light;
an optical system that transforms planar light from the light-emitting unit into non-circular light and that causes the non-circular light to be incident on one side face of the light guide element; and
a lens means formed on the one side face of the light guide element on which the transformed non-circular light is incident, the lens means condensing the transformed non-circular light,wherein the light condensed by the lens means is emitted, onto a road surface in front of the vehicle, from the other side face opposite to the one side face of the light guide element, andthe light-emitting unit emits white light including red light.

Abstract
Provided is a vehicular lighting apparatus which is relatively small, can be manufactured at low cost, is superior in mountability to an automobile, and is superior in recognizeability of an object illuminated by a head lamp. The vehicular lighting apparatus attachable to a front end part of a vehicle includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits illumination light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle. The light-emitting element emits whit light including red light.
