摘要： 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.

摘要： Communications system for motor vehicles are provided, that comprise a plurality of transmission devices and a plurality of receiver devices where the transmission devices, individually or together, feature several light sources that are able to emit at least light with a first wavelength spectrum and light with a second wavelength spectrum. The transmission devices feature means of modulation that can effect modulation of the light such that information can be transmitted via the light. Receiver devices can capture the emitted light and extract the information from the captured light. The communications system is designed in such a way that the light with the first wavelength spectrum is used for the transmission of information in a first category and the light with the second wavelength spectrum is used for the transmission of information in a second category.

摘要： 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.

摘要： Lighting device for a vehicle, comprising a lighting module having at least one light source and one luminous surface which is illuminated by the light source, from which light emanates during operation of the lighting device, as well as a liquid crystal display which is arranged at least partially in front of the luminous surface in such a way that, during operation of the lighting device, at least one portion of the light emerging from the luminous surface enters an entrance surface of the liquid crystal display and emerges from an exit surface of the liquid crystal display, wherein the lighting device is configured to control the liquid crystal display, in a targeted manner, in order to allow portions of the light impinging on the entrance surface to pass through the liquid crystal display and not to allow other portions of the light impinging on the entrance surface to pass through the liquid crystal display.

摘要： A method is provided for mounting a light module. A light module that is mounted by means of such a method includes at least one light source for emitting light, and at least one optical element for forming the beam of light. The relative arrangement between the light source and the optical element is adjusted via the following steps. The light module is arranged in an adjusting device, and a light detection device is provided. The light source is switched on, and the light detection device is illuminated with the light. A set deviation between a value and an actual value of a light field generated with the light as compared to a required light field is measured. The relative arrangement between the light source and the optical element is then adjusted until the set/actual deviation is minimal or zero.
