Patent ID: 7416322

Claim:
A vehicle lighting device, comprising: a light emitting element disposed such that an optical axis of the light emitting element extends in a longitudinal direction of the lighting device in such a manner as to be directed to the front of the lighting device, a primary reflector for reflecting light from the light emitting element towards the rear of the lighting device, and a secondary reflector for reflecting the light from the light emitting element that is reflected on the primary reflector to the front of the lighting device, wherein a reflecting surface of the primary reflector has a shape of a substantially dome-shaped body of revolution that is formed by rotating an ellipse about the optical axis, the ellipse having a primary focal point which is a point near the light emitting element and a secondary focal point which is a point near the reflecting surface, and wherein the primary reflector includes a belt-shaped region that is a light translucent portion, the belt-shaped region straddles a ring-shaped locus, which is formed by the secondary focal points of the ellipse rotated about the optical axis.
