Abstract

The headlamp has a reflector (10) and a light source (12). Disposed in the ray path of the light reflected from the reflector (10) there is a lens (18), which is received in a mounting (20) and consists of an elastically deformable material. The lens (18) is acted upon by at least one control element (22), by which a force can be applied to the lens (18) in order to deform it. The light passing through the lens (18) is influenced, i.e. deflected in its direction. In the nondeformed state of the lens (18) the light beam radiating from the headlamp exhibits a first characteristic, i.e. direction and scatter, and in the deformed state of the lens (18) the light beam radiating from the headlamp, because of the then different optical effect of the lens (18), exhibits a different, second characteristic.
