Abstract:
1. A vehicle headlamp, comprising; a light source emitting a light flux; an imaging optics projecting the light flux into an area in front of the vehicle headlamp; a diaphragm arranged between the light source and the imaging optics, the diaphragm having an edge that delimits the light flux of the light source of the vehicle headlamp creating a light/dark boundary of the light flux projected by the imaging optics; a boundary surface of the imaging optics through which the light flux penetrates, the boundary surface having a plurality of overhead elements in the form of a local deformation of the boundary surface each having a prismatic effect by means of individual surfaces which deflect the light into an area lying over and below the light/dark boundary; wherein each overhead element has at least one surface deflecting a first amount of the light over the light/dark boundary and one surface deflecting a second amount of the light below the light/dark boundary and the boundary surface has more than one hundred overhead elements distributed discretely over the boundary surface.
