Abstract

A motor vehicle headlamp of a motor vehicle includes a first motor vehicle headlamp and a second motor vehicle headlamp. The first and second motor vehicle headlamp include an illuminant for a low-beam light, a high-beam light and an ambient light above a propagation direction of a light distribution of the high-beam light. The ambient light can be emitted each combined with low-beam light and/or high-beam light and is separately adjustable for each headlamp.

Claims

1-15. -15. (canceled)

16. A motor vehicle headlamp arrangement of a motor vehicle comprising:

a first headlamp having a first illuminant for emitting a low-beam light, a high-beam light and an ambient light;

a second headlamp having a second illuminant for emitting a low-beam light, a high-beam light and an ambient light;

wherein each of the first and second headlamp is configured to emit ambient light having a propagation direction of light distribution above a propagation direction of light distribution of the high-beam light;

wherein the ambient light from each of the first and second headlamps is combined and emitted with at least one of the low-beam light or the high-beam light; and

wherein the ambient light is separately adjustable for each of the first and second headlamps.

17. The motor vehicle headlamp arrangement according to claim 16, wherein a lower limit for the propagation direction of the ambient light is inclined upwards with an angle of inclination of at least 2.5 relative to a road plane.

18. The motor vehicle headlamp arrangement according to claim 16, wherein the ambient light for each of the first and second headlamp is laterally adjustable separately.

19. The motor vehicle headlamp arrangement according to claim 16, wherein the propagation direction of the ambient light from the first headlamp is configured to shine into a direction that is different than the propagation direction of the ambient light from the second headlamp.

20. The motor vehicle headlamp arrangement according to claim 16, wherein the first and second headlamps are configured to blank out a region from the light distribution.

21. The motor vehicle headlamp arrangement according to claim 16, wherein the first and second headlamps each comprises at least one matrix headlamp.

22. The motor vehicle headlamp arrangement according to claim 16, wherein for the ambient light wises at least a partial defocusing of a light beam.

23. The motor vehicle headlamp arrangement according to claim 16, further comprising a detector configured to detect traffic signs in a travelling direction and a control in communication with the detector and operably with at least one of the first and second headlamps to direct ambient light onto at least one traffic sign detected by the detector.

24. The motor vehicle headlamp arrangement according claim 16, further comprising a detector for determining a location of an oncoming vehicle and a control in communication with the detector and configured to blank out a partial region of the light distribution corresponding to the location of the oncoming motor vehicle.

25. The motor vehicle headlamp arrangement according to claim 16, further comprising a detector configured to determine a viewing direction of a driver, an optical element associated with at least one of the first and second headlamps and a control configured to actuate the optical element as a function of the viewing direction of the driver.

26. A motor vehicle with a motor vehicle headlamp arrangement according to claim 16.

27. A method for operating a motor vehicle headlamp system for emitting a variable light distribution comprising:

providing a headlight arrangement for emitting a low-beam light, a high-bean light and an ambient light upwardly from a road plane and obliquely to at least one side;

detecting a traffic sign a camera; and

activating the headlight arrangement with a control to emit the ambient light when the traffic sign lies outside an active illumination of the low-beam light or the high-beam light.

28. The method according to claim 27, further comprising detecting a viewing direction of a driver with a driver monitoring device and activating the ambient light when the viewing direction lies in an angular range of at least 2 towards the top relative to the road plane.

29. The method according to claim 27, further comprising blanking out a part region from the illumination of the headlamp arrangement.

30. The method according to claim 29, further comprising activating the ambient light when the part region lies in a range of vision of the driver.
