Abstract
The invention relates to a vehicle headlamp (501), comprising a light source unit (502), a controllable reflector (590), an optically transparent cover (504), an optical absorber device (505), an optical shielding element (506), and a projection optics (507). The light source unit (502) is designed to emit light and to illuminate in a first direction of propagation (510), in the optical path of which the controllable reflector (590) is arranged, and the controllable reflector (590, 690, 70) at least partially reflects the light in a second direction of propagation (520), in the optical path of which the projection optics (507) is arranged and is oriented in a direction in front of the vehicle, in order to form a light pattern in front of the vehicle. The optically transparent cover (504), is arranged in a second plane (551) between the light source unit (502) and the controllable reflector (590) in such a way that light passes through the optically transparent cover (504) in the first direction of propagation (510) and in the second direction of propagation (520). The light emitted by the light source unit (502) is incident on the optically transparent cover (504) in the first dire…
