Abstract

The head lamp has a cup-shaped reflector (1) with an associated light source and a screen arrangement between the light source and a lens for producing several screened light figures. The screen arrangement has a fixed screen (3) for main beam, a first adjustable screen (4) for asymmetric dipped beam and a second adjustable screen (5) for producing a symmetric beam with the first adjustable screen in its active position.
