Abstract

A vehicle lighting unit can be configured to allow the brightnesses of light observed through vertically arranged lenses to substantially match when the lenses are viewed from a certain viewpoint in front of the vehicle. The vehicle lighting unit can include: a first lens on a first upper optical axis; a second lens on a second lower optical axis; a semiconductor light-emitting device; a first revolved ellipsoidal reflector; a shade; a second revolved ellipsoidal reflector; and a third reflector. The third reflector is inclined at an inclination angle with respect to the horizontal plane adjusted such that light emitted from the semiconductor light-emitting device, reflected by the second reflector, focused at a second focal point of the second reflector, reflected by the third reflector, and passing through the second lens is directed in a direction at a predetermined upward angle with respect to the horizontal plane.
