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.
