  • Publication number: 20240093852
    Abstract: A headlight for a motor vehicle having at least one light source which emits light during operation of the headlight. A primary optical system has at least one light entry surface for the light emitted by the at least one light source and at least one light exit surface. A secondary optical system, which, during operation of the headlight, projects the light emitted from the at least one light exit surface of the primary optical system into the space outside the motor vehicle where it produces a light distribution which has a horizontal cut-off line and light portions located above the cut-off line in order to implement an OS function (overhead sign function). The headlight being designed such that a portion of the light emitted by the primary optical system is reflected back to the primary optical system by the secondary optical system.

  • Patent number: 11739901
    Abstract: A projection headlight for vehicles, having a first lighting unit containing a light source and a primary optical unit for pre-shaping light exiting the light source, a second lighting unit containing a light source and a primary optical unit for pre-shaping the light exiting the light source, a secondary optical unit for imaging the light exiting the primary optical unit of the first lighting unit in a region in front of the vehicle as a first light distribution and light exiting the primary optical unit of the second lighting unit as a second light distribution, an actuator for actuating the first lighting unit and the second lighting unit in order to generate the light distribution consisting of the first light distribution and the second light distribution, a diaphragm with a diaphragm edge for producing a light-dark boundary in the first light distribution.

  • Publication number: 20230014251
    Abstract: A head lamp module for a motor vehicle is provided, and includes one single printed circuit board, a first group of light sources, a second group of light sources, a lens and an optical device. The first group of light sources and the second group of light sources are both arranged on the printed circuit board. The first group of light sources and the second group of light sources emit light to the optical device. The optical device is adapted to guide the emitted light in a direction towards the lens. The light leaves the head lamp module through the lens.

  • Patent number: 10900630
    Abstract: A headlight, in particular a headlight of a motor vehicle, having at least one first light source for a high beam, which emits light during operation of the headlight, and a first light guide having at least one light entry surface for the light emerging from the at least one first light source and at least one light exit surface, and at least one second light source for a low beam, which emits light during operation of the headlight, and a second light guide, which has at least one light entry surface for the light, emerging from the at least one second light source, and at least one light exit surface.

  • Patent number: 9719646
    Abstract: A headlamp for vehicles having a projection module containing a first light source for generating a first light bundle, a reflector assigned to the first light source, a lens, and an edge disposed in a focal plane for generating a low beam light distribution. The headlamp also includes a second light source for generating a second light bundle and an optics unit disposed between the lens and the second light source for generating a supplementary light distribution, such that by superimposing the supplementary light distribution and the low beam light distribution, a high beam light distribution is formed. The optics unit is formed by a flat waveguide having a light entry surface for receiving the second light bundle emitted from the second light source.

  • Publication number: 20130039086
    Abstract: The invention concerns a headlamp for vehicles with a housing, which provides a light module containing a light source, a reflector assigned to the light source, a lens located in front of the reflector and a shutter located between the lens and the reflector whereas in an area above the shutter a diffuser lens element for scattering a light beam emitted directly by the light source shall be located.
