Abstract: A method is provided for operating an illuminating device for a vehicle that features means of influencing light or a plurality of light sources for the targeted generation of pixels of a light distribution. In the event of failure of at least one pixel of the light distribution caused by a defect in one section of the means of influencing light or by malfunction of one of the light sources, at least one non-defective section of the means of influencing light or at least one non-malfunctioning light source is actuated in order to correct the light distribution. The at least one non-defective section of the means of influencing light or at least one of the non-malfunctioning light sources is actuated in such a way that at least one pixel of the light distribution adjacent to the at least one malfunctioning pixel is reduced in its brightness.

Abstract: 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.

Abstract: 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.

Abstract: A laser light source unit for vehicles, with a resonator containing a first end mirror and a second end mirror, between which an active laser medium is arranged, and with a pump device for generating pump radiation, which can be introduced into the resonator via the first end mirror, wherein a rotatable birefringent medium is arranged in the resonator such that, according to a rotation of the birefringent medium, preferred radiation of different wavelengths is stimulated in the active laser medium.

Abstract: 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.
