ABSTRACT:
A vehicle light emitting device including a light emitting element, a primary reflector, and a secondary reflector. A reflecting surface of the primary reflector has a shape of a substantially dome-shaped body of revolution formed by rotating about the optical axis Ax an ellipse E which has a primary focal point F1which is a point near the light emitting element and a secondary focal point F2which is a point near the reflecting surface. The primary reflector includes a belt-shaped region, which straddles a ring-shaped locus of the secondary focal point F2and is configured as a light translucent portion, whereby reflected light from the primary reflector is caused to temporarily converge on the secondary focal point F2in each cross-section of the body of revolution including the optical axis Ax and is thereafter caused to be incident on the secondary reflector as a diffused light.
