  • Patent number: 9476558
    Abstract: The invention relates to a projection lens for use in an LED module of a motor vehicle headlamp. The LED module has a light source in the form of an LED matrix including numerous LED chips disposed in a matrix adjacent to and/or above one another, a primary lens including numerous primary lens elements disposed in a matrix adjacent to and/or above one another for bundling light emitted from the light source, and a projection lens. The projection lens projects a light exit surface of the primary lens to generate a predefined light distribution on a surface in front of the vehicle. The projection lens is designed such that it generates at least two separate images of the light exit surface of the primary lens on its image side, which are offset to one another in the horizontal direction.

  • Patent number: 8636397
    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.

    Abstract: There is presented a vehicle headlamp (1) with an imaging optics that is designed to project, as light/dark boundary, into the area in front of the vehicle headlamp (1), an edge that delimits a light flux of a light source (18) of the vehicle headlamp (1), a boundary surface (32) of a component (26) of the imaging optics, through which the light flux penetrates, having an overhead element (34) in the form of a local deformation of the boundary surface (32) 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 (1) is distinguished by the fact that the boundary surface (32) has more than one hundred overhead elements (34) distributed discretely over the boundary surface (32).
