Abstract

A vehicle lighting device includes a semiconductor light source (1) constituted of a rectangular light emitter (5) and a lens (2) constituted of a composite lens with multiple optical axes sharing a single focal point. The lens (2) emits a light from the rectangular light emitter (5) as a spot-type light distribution pattern extended in an arbitrary direction.
