Abstract

The headlamp has a light source (1), a main reflector (2) and a light panel (3), whereby an optical axis (5) is defined by the main reflector, and a retroreflector (6) between the light source and light panel with a light passage opening essentially centrally symmetrical to the optical axis of the main reflector. The retroreflector can be inclined to the optical axis and can have a square light opening.
