摘要： The invention relates to a motor vehicle headlight (100), comprising a headlight housing (102) and a cover plate (103) having at least one light source (104, 105) arranged in said motor vehicle headlight (100). In order to cool the at least one light source (104, 105), a heat sink device (200) is provided. Said heat sink device (200) comprises two heat sink elements (106, 107, 201, 202, 501, 502, 601, 602, 701, 702, 801, 802, 901, 902, 1001, 1002) that are separated from one another by an air gap (209) and that are arranged in such a way that a first heat sink element (106, 201, 501, 601, 701, 801, 901, 1001) is mounted inside the motor vehicle headlight (100), and a second heat sink element (107, 202, 502, 602, 702, 802, 902, 1002) is mounted outside the motor vehicle headlight (100). The heat sink device (200) is provided with a contacting device (210) that allows a heat exchange between the heat sink elements (106, 107, 201, 202, 501, 502, 601, 602, 701, 702, 801, 802, 901, 902, 1001, 1002) via said contacting device (210), whenever the temperature inside the motor vehicle headlight (100) is higher than the temperature in the area outside the motor vehicle headlight (100), and no heat exchange between the heat sink elements (106, 107, 201, 202, 501, 502, 601, 602, 701, 702, 801, 802, 901, 902, 1001, 1002) is possible whenever the temperature inside the motor vehicle headlight (100) is lower than the temperature in the area outside the motor vehicle headlight (100).

摘要： In order to determine a zero position of the actuating drive (14) of a luminous range adjustment of a light module (10) in a headlamp for vehicles, light coming from the light source (1) is directed onto an absorber surface (12). The absorber surface (12) has an opening, through which light passes as a delimited light beam (17). By means of the actuating drive (14), the light module (10) is pivoted in terms of its angle position, an intensity of the light beam (17) passing through the opening being detected by means of a light-sensitive sensor (15) which is arranged behind the absorber surface (12).

摘要： A method for controlling an adaptive motor vehicle headlight (AMVH), wherein a first data storage device (DSD) is assigned to the AMVH, which is designed to emit different segmented light distributions having a resolution of at least 2×12 and has light sources arranged in segments for this purpose, each segment including at least one LED light source. The method includes: a) providing the AMVH and the first DSD and storing a number of data sets on the first DSD, b) connecting the AMVH to a motor vehicle, which is designed to output control data for controlling the AMVH, c) transmitting the control data by the motor vehicle to the AMVH, wherein the AMVH has an internal computing unit, which receives the control data and selects and retrieves data sets stored in the first DSD as a function of the control data (“active data sets”),d) controlling the light sources arranged in the segments by the computing unit in accordance with the active data sets, d1) determining the number of active data sets, wherein the control data is used to give each active data set an individual percentage weighting, d2) determining target light intensities to be output of each segment by superimposing the light intensity values that can be derived from the active data sets taking the respective weighting into account, d3) outputting the target light intensities for each segment taking into account a permissible maximum temporal rate of change of the light intensity that can be predetermined.

摘要： The invention relates to a lighting device for a motor vehicle (10) that has one or preferably two such lighting devices that are set up to produce a headlamp flasher signaling function, the lighting device being associated with a controller, the controller controlling the lighting device upon activation of the headlamp flasher signaling function to produce, from the lighting device, a headlamp flasher light distribution, especially in the form of a high beam light distribution (LHV), especially for a defined period of time, in an area in front of the at least one lighting device or in an area in front of the vehicle (10). It is provided that in the case in which the motor vehicle is located on a one-way multilane road (FB) that can only be traveled in one direction (R) and a motor vehicle (20) is driving in front in the lane (FS1) of the motor vehicle (10), the at least one lighting device is set up to produce, in accordance with control commands of the controller (7), a modified headlamp flasher light distribution which only illuminates a subarea (LHV′) of the area (LHV) illuminable by the unmodified headlamp flasher light distribution.

摘要： A headlamp (1) for vehicles having at least one laser light module (3l, 3m, 3r) which has a laser light source (11) and a phosphorus element (13) which is arranged downstream of the latter in the beam path and a front-end optical system (16) in which the at least one laser light module is arranged in a housing (2) of the headlamp which has a projection optical system (4) for projecting the light distribution generated in the focal plane of the projection optical system of the at least one laser light module into the carriageway space, and at least one deflection prism (20; 22, 23) is integrated into the at least one front-end optical system (16), which deflection prism (20; 22, 23) lies in the region of the laser beam (15; 15-1, 15-2) which occurs when the phosphorus element (13) is defective or missing and which deflects this laser beam occurring in the event of disruption and keeps it away from the projection optical system and therefore from the carriageway space.
