摘要： A headlamp, and in particular a headlamp for a motor vehicle, comprising a digital micromirror device which reflects light hitting it so that it exits at least partially from the headlamp when the headlamp is operated. The headlamp also includes at least one first light source which emits light with a first luminance, and which hits the digital micromirror device at least partially when the headlamp is operated. The headlamp also includes at least one second light source emitting light when the headlamp is operated, and having a second luminance which is different from the first luminance. The light emitted from the at least one second light source hits, at least partially, the digital micromirror device. The areas of incidence of the light emitted by the light sources on the digital micromirror device overlap at least partially. On the digital micromirror device, the range of incidence of the light emitted by the at least one first light source differs from the range of incidence of the light emitted by the at least one second light source.

摘要： 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.

摘要： A lens holding arrangement for lenses of an illumination device for vehicles is provided. The holding arrangement includes a surrounding body which surrounds a number of lenses arranged coaxially to each other and at an axial distance to each other. The holding arrangement also includes a number of attachment elements on an inner surface to which the lenses make contact with a front or back edge. The surrounding body is segmented with a number of segments that surround in each case the lenses in a circumferential angle range (φ), and with fasteners for fastening the segments.
