Abstract

The invention relates to a headlight for a motor vehicle having a plurality of main light modules configured to produce a main light distribution for low beam and high beam. The headlight also has a laser light module comprised of one or more laser diodes configured to produce a laser light distribution in addition to the main light distribution. The headlight is configured such that, during operation, the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution.

First claim

What is claimed is:

1. A headlight for a motor vehicle, comprising:
a plurality of main light modules configured to produce a main light distribution for a low beam and a high beam;
a laser light module comprised of one or more laser diodes configured to produce a laser light distribution in addition to the main light distribution,
wherein the headlight is configured such that, during operation, the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution;
wherein the laser light module is pivotable in a horizontal direction and a vertical direction independently of the plurality of main light modules by an actuator system which converts electrical current into a mechanical movement of the laser light module to effect a movement of the laser light distribution in the manner decoupled from the main light distribution and relative to the main light distribution.

2. The headlight as claimed in claim 1 , wherein one or more of the plurality of main light modules are LED light modules each comprising one or more LEDs to produce the main light distribution.

3. The headlight as claimed in claim 1 , wherein one or more of the plurality of main light modules are segmented light modules that each produce, during operation, a light distribution from segments which are able to be switched on and off.

4. The headlight as claimed in claim 1 , wherein one or more of the plurality of main light modules are attached rigidly in the headlight.

5. The headlight as claimed claim 1 , wherein the headlight is configured such that, in an operating mode of the headlight, regions of the main light distribution which do not result in dazzling other road users are intensified.

6. The headlight as claimed in claim 1 , wherein the headlight is configured such that, in an operating mode of the headlight, one or more objects which are situated in front of the headlight in an emission direction are illuminated.

7. The headlight as claimed claim 1 , wherein the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution such that a light region outside of the main light distribution is illuminated by the laser light distribution.

8. A motor vehicle comprising a headlight, wherein the headlight comprises:
a plurality of main light modules configured to produce a main light distribution for a low beam and a high beam;
a laser light module comprised of one or more laser diodes configured to produce a laser light distribution in addition to the main light distribution,
wherein the headlight is configured such that, during operation, the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution;
wherein the laser light module is pivotable in a horizontal direction and a vertical direction independently of the plurality of main light modules by an actuator system which converts electrical current into a mechanical movement of the laser light module to effect a movement of the laser light distribution in the manner decoupled from the main light distribution and relative to the main light distribution.

9. The motor vehicle as claimed claim 8 , wherein the laser light distribution is movable in a manner decoupled from the main light distribution and relative to the main light distribution such that a light region outside of the main light distribution is illuminated by the laser light distribution.
