Abstract
There is presented a vehicle headlamp with an imaging optics that is designed to project, as light/dark boundary, into the area in front of the vehicle headlamp, an edge that delimits a light flux of a light source of the vehicle headlamp, a boundary surface of a component of the imaging optics, through which the light flux penetrates, having an overhead element in the form of a local deformation of the boundary surface having a prismatic effect by means of which the light is deflected into an overhead area lying over the light/dark boundary. The vehicle headlamp is distinguished by the fact that the boundary surface has more than one hundred overhead elements distributed discretely over the boundary surface.
