Abstract

The headlamp has a shell-shaped reflector (1), a light source (2) associated with the reflector, a lens (3) arranged in the light path of the reflector to collect light reflected from the reflector with a convex side (4) remote from the reflector and a stop enclosing the lens. The stop is in the form of a fill-in reflector (5) for collecting the light (7) from the light source that f encloses the lens and has a focal region associated with the lens.
