Abstract
A headlamp for vehicles with a laser module comprising a laser light source for the radiation of a laser light beam, and an optic unit to shape the laser light beam to form a given light distribution. The optic unit has a primary optic device for the imaging of an intermediate image on an intermediate image plane. The optic unit has a deflection device which is arranged in an intermediate image plane and which has a limiting edge by means of which a share of the light of the laser light beam is deflected along a light path in the direction of a bundling device, by means of which the share of light is deflected into a light distribution while forming a cut-off line.

A headlamp for vehicles with a laser module, the laser module comprising:
- a laser light source for the radiation of a laser light beam;
- and
- an optic unit to shape the laser light beam to form a given light distribution,
- wherein the optic unit has a primary optic device for the imaging of an inter-mediate image on an intermediate image plane, and
- wherein the optic unit has a first deflection device with a limiting edge arranged in the intermediate image plane, by means of which a first share of light of the laser light beam is deflected along a first light path in a direction of a first bundling device, by means of which the first share of light is deflected to form a first partial light distribution while forming a cut-off line, and
- the optic unit has a second deflection device, by means of which a second share of light of the laser light beam not deflected by the first deflection device is deflected along a second light path in a direction of a second bundling device by means of which the second share of light is deflected to a second partial light distribution so that the second partial light distribution overlaps the first partial light distribution so that they form a light distribution, and wherein
- the second share of light is deflected at an acute angle (φ) relative to the first share of light with regard to a projection plane running vertically relative to a main radiation direction (H).
