摘要： A headlamp assembly for illuminating surroundings of a vehicle, including at least one headlamp, a temperature sensor, and a control device. The at least one headlamp comprising a multiplicity of light sources, the multiplicity of light sources (being divided into a first group and at least one second group. The temperature sensor being configured to detect a temperature in the at least one headlamp. The light sources of the multiplicity of light sources being thermally coupled. The control device being configured to ascertain a current temperature ascertained by the temperature sensor in the at least one headlamp and, in the case that the current temperature in the at least one headlamp exceeds a predefined temperature threshold value, to select the first group or the at least one second group for a power reduction, depending on an operating situation of the vehicle and to reduce the power of the selected group.

摘要： An illuminating device for vehicles, including a first light unit, which contains a first light source having a number of first light pixels for generating a first partial light distribution including a second light unit, which contains a second light source having a number of second light pixels for generating a second partial light distribution. The second light pixels are arranged in a boundary region of the second light source and are controllable as a group in such a way that a number of the second light pixels controlled as a group in the boundary region of the second light source per unit of surface area increases from a first end of the boundary region in the direction of a second end of the boundary region.

摘要： A method for controlling a headlamp of a motor vehicle, the headlamp comprising a plurality of light sources. A projection symbol to be projected by the headlamp and a position and a size of the projection symbol are determined. A respective first luminous intensity for the light sources for the projection of the projection symbol at the position with the size and a first indicator, which contains an indication of how greatly the individual first luminous intensities differ from one another are determined. The position and/or the size of the projection symbol is changed. A respective second luminous intensity for the light sources for the projection of the projection symbol at the changed position and/or with the changed size and a second indicator, which contains an indication of how greatly the individual second luminous intensities differ from one another are determined. The projection symbol subsequently projected.

摘要： A method for controlling two lighting modules of a headlight, including the following steps: definition of a non-dazzling region, wherein the non-dazzling region is at least within the second region; reduction of the brightness of the light emitted by the two lighting modules toward the non-dazzling region; determination as to whether an adjacent region exists that directly adjoins the non-dazzling region horizontally and that is a horizontal edge region of the first region; and reduction of the brightness of the light emitted by the first lighting module toward the adjacent region if the adjacent region has been determined.
