A Fresnel projection lens for a headlight of a motor vehicle having a light entry surface, wherein the light entry surface has a smooth or substantially smooth surface, and with a light exit surface. The light exit surface has a plurality of adjacent, in particular annular, flanks, wherein one flank each comprises a bottom, an effective facet, and an interfering facet arranged at a first pitch angle to the effective facet. The effective facet and the interfering facet form a cut edge opposite the bottom. A pass-through area is provided on at least one of the flanks, wherein the pass-through area is angled to the effective facet.

A lighting device for a motor vehicle, wherein the lighting device has a circuit board with a multiplicity of light-emitting diodes arranged thereon, a transparent optical layer, and a reflector element, wherein the reflector element is arranged between the circuit board and the optical layer, wherein the reflector element has multiple segments into which the reflector element is subdivided, wherein a segment is associated with each light-emitting diode so that light emitted by the light-emitting diodes can be reflected by the reflector element and can pass through the optical layer. Two light-emitting diodes are arranged in a segment. In addition, a lighting system and a motor vehicle are provided.

Lighting device for a motor vehicle

A structural unit for provision in the front end or in the tail end of a motor vehicle, wherein the structural unit comprises a support body and at least two environment sensing systems, wherein the environment sensing systems are received on the support body.

Structural unit for provision in the front end or tail end of a motor vehicle

A lighting device for a motor vehicle, in particular a headlamp, comprising at least two, preferably three, light sources, from which light emanates during the operation of the lighting device, the light of each of the light sources differing from that of the other light sources with regard to its wavelength spectrum, comprising modulator, which bring about a modulation of the light emanating from the light sources during the operation of the lighting device, so that information is transmitted by the light, the lighting device having a mixer for mixing the light emanating from the individual light sources, so that white light emerges from the lighting device during the operation of the lighting device.

Illumination device for a motor vehicle

A headlight for a vehicle with a cooling device for a semiconductor illuminant, wherein the cooling device comprises a fluid circuit with an evaporator, on or in which the semiconductor illuminant is arranged and a cooling medium can be evaporated, and wherein the cooling device further comprises a condenser on or in which the cooling medium can be condensed. The cooling medium comprises a first coolant, which has a first lower evaporation temperature and the cooling medium comprises a second coolant, which has a second higher evaporation temperature.

A method for detecting misadjustments of a headlamp of a vehicle and to a device for this purpose. It is provided that the vehicle is provided with a detector with which at least one light signal of another road user is detected, and wherein the vehicle is equipped with a control unit with which light signal information of the detector is captured and by means of which adjustment information for correcting the misadjustment of the headlamp is output as a function of the captured light signal information.

Method for detecting misadjustments of the cut-off line of a headlamp

A lighting device for vehicles having a housing, in which a light source unit for emitting a light beam and an optical unit associated with the light source unit for generating a predetermined light distribution are disposed, with a cover plate closing an opening of the housing and with a cooling element for dissipating heat from the light source unit. The cooling element is associated with a heat-dissipating optical element of the optical unit. A dividing wall separating the housing into a first chamber and into at least a second chamber is provided, wherein in the first chamber, the first cooling element associated with the light source unit, and in the second chamber, the second cooling element associated with the heat-dissipating optical element of the optical unit are arranged.
