ABSTRACT:
A headlight for vehicles has a light source, a reflector having at least two different reflector regions including a first reflector region which reflects a light emitted by the light source as a converging light beam to form low beam and a second reflector region formed so that light emitted by the light source and reflected by the second reflector region together with the light emitted by the light source and reflected by the first reflector region form high beam, a lens arranged after the reflector in a light outlet direction so that at least the light which forms low beam passes through the lens, and a screening device arranged between the reflector and the lens, the screening device having a stationary screening part and a movable screening part, the movable screening part being movable between a position for low beam in which light forming low beam can pass along the movable screening part and a position for high beam in which additionally the light reflected by the second reflector region can pass along the movable screening part at least partially, so that in the position for low beam an edge of the screening device forms a bright-dark limit of low beam, the screening parts each having a plurality of openings formed so that in the position of the movable screening part for low beam the movable screening part covers the openings of the stationary screening part, and in the position for high beam the openings of the movable screening part coincide with the openings of the stationary screening part at least approximately so that the screening device forms throughgoing openings for the light.
