Abstract

Vehicle lighting unit (10) allows the brightnesses of light observed through vertically arranged lenses to substantially match when the lenses are viewed from a certain viewpoint. A first reflector (13) includes a revolved ellipsoidal reflector having a first focal point (F1 13 ) at or near a semiconductor light-emitting device (12) and a second focal point (F2 13 ) at or near the vehicle rear-side focal point of a first lens (11A), and a second reflector (15) includes a revolved ellipsoidal reflector having a first focal point (F1 15 ) at or near the semiconductor light-emitting device (12) and a second focal point (F2 15 ) between the second reflector (15) and a third reflector (16). The third reflector (16) is inclined at an upward angle such that light emitted from the semiconductor light-emitting device (12), reflected by the second reflector (15), focused at the second focal point (F2 15 ) of the second reflector (15), reflected by the third reflector (16), and passing through the second lens (11B) is directed at a predetermined upward angle.
