A headlight for a vehicle with a light source and a lens arrangement associated with it, containing a light entry surface on a side facing the light source and a light emission surface on a side facing away from the light source, wherein light emitted by the light source is mapped by means of the lens arrangement to a predetermined light distribution. A scattering optic part is assigned to the lens arrangement for scattering the light emitted by the lens arrangement. The surface structuring of the scattering optic part has a plurality of cone-shaped optical elements arranged in a row, which are arranged alternately curved in the row direction, wherein a second cone-shaped optical element adjacent to a first cone-shaped optical element is formed by twisting the first cone-shaped optical element on two perpendicular axes.

Headlight for vehicles

A lighting device for a motor vehicle having a multiplicity of light sources from which light radiates in operation of the lighting device, an optical component that has at least one light entry surface for the light radiating from the light sources and at least one light exit surface for the light that has entered through the at least one light entry surface, as well as a secondary optical system that has at least one light entry surface for the light radiating from the at least one light exit surface of the optical component as well as at least one light exit surface for the light that has entered through the at least one light entry surface, wherein the light that has exited from the at least one light exit surface of the secondary optical system produces a light distribution outside the motor vehicle in operation of the lighting device.

Lighting device for a motor vehicle headlight with a first optical component and second optical system

A method for producing an optical component for an illuminating device of a motor vehicle, the optical component having at least one structured surface, comprising the following method steps: generating a first virtual representation of the surface that is to be structured of the component, applying a grid of points to the virtual representation of the surface that is to be structured of the component, shifting all or a plurality of the points in a randomized manner in the positive or negative direction in parallel with the respective normals to the surface in order to structure the surface, creating a second virtual representation of the surface that reproduces the structuring achieved by the shifting of the points, and producing the component on the basis of the second virtual representation of the surface.

Method for producing an optical component, optical component and illuminating device for a motor vehicle

A headlight for vehicles having a projection module containing a low beam primary lens and a first light source, a high beam primary lens and a second light source, a secondary lens arranged in the main beam direction in front of the low beam primary lens and the high beam primary lens, a secondary lens by means of which, in a low beam mode, in which only the first light source is activated, a first light bundle emitted from the low beam primary lens is mapped according to a specified low beam distribution and, in a high beam mode, in which the first light source and the second light source are activated, the first light bundle is mapped together with the second light bundle emitted from the high beam primary lens in order to produce the high beam distribution, wherein the high beam primary lens has compensator.

A lighting device for vehicles, having a light source unit containing a plurality of light sources for emitting light and having a planar light guide body associated with the light source unit containing a flat surface portion with at least two opposite flat surfaces extending from a light input side of the flat surface portion to a light output side thereof, wherein the light can be coupled out at a narrow side of the light output side for the generation of a light distribution and comprising a deflection section for the deflection of the light emitted by the light source unit in the direction of the narrow side of the flat surface portion coupling out the light.
