A headlamp for a motor vehicle is provided, the headlamp including a plurality of first light sources for a high beam, emitting light during operation of the headlamp, and a plurality of second light sources for a low beam, emitting light during operation of the headlamp. The headlamp also includes a first light guide having a plurality of light entry surfaces for the light emitted from the first light sources and a first light exit surface, as well as a second light guide having a plurality of light entry surfaces for the light emitted from the second light sources and a second light exit surface. An optical component is also provided, which may be a monolithic optical component, and which comprises both the first and the second light guide.

Headlamp for a motor vehicle

A lighting device for vehicles having a light source apparatus for emitting light, having an optical apparatus, which contains a lens arrangement with a multiplicity of lenses, for deflecting the light in accordance with a specified light distribution, and having a positioner for adjusting a lens along an optical axis of the lens arrangement, wherein the positioner is implemented as an apparatus for setting basic scatter width in such a manner that light can be projected in different scatter widths for a specified basic lighting function.

Lighting device and production method

A lighting device for vehicles having a first light source, a second light source and a light-shaping apparatus allocated to the first light source and the second light source, wherein the second light source is offset in relation to the first light source, at least in a direction running perpendicularly to the optical axis of the light-shaping apparatus. The light that is incident on the light-shaping apparatus from the first light source is deflected to produce a first light function and wherein the light that is incident on the light-shaping apparatus from the second light source is deflected to produce a second light function, wherein the light-directing surface of the light-shaping apparatus has a free-form surface comprising multiple varyingly curved surface elements.

Headlight lens with two tunnel sections for separate light entry surfaces for a vehicle headlight

A headlamp for vehicles having a projection module containing a first light source for generating a first light bundle, a reflector assigned to the first light source, a lens, and an edge disposed in a focal plane for generating a low beam light distribution. The headlamp also includes a second light source for generating a second light bundle and an optics unit disposed between the lens and the second light source for generating a supplementary light distribution, such that by superimposing the supplementary light distribution and the low beam light distribution, a high beam light distribution is formed. The optics unit is formed by a flat waveguide having a light entry surface for receiving the second light bundle emitted from the second light source. The second light source is disposed in the proximity of the light entry surface, having a light exit surface, and flat sides extending between the light entry surface and the light exit surface, on which entering light can be conducted through total reflection. A light/dark border of the low beam light distribution is formed by the edge of the flat waveguide formed as the front outer edge, which connects the light exit surface and an upper flat side of the waveguide. The upper flat side of the flat waveguide is provided with a light blocking coating, such that an entry of light beams from the first light bundle striking the upper flat side is prevented.
