A light module of a lighting equipment of a motor vehicle that includes several separately controllable light sources combined in an array, several primary optics elements in the form of collective lenses, each of which has a light ingress surface and a light emitting surface, that are combined to a primary optics array, wherein the primary optics elements concentrate at least a portion of the light emitted by the light sources and generate intermediate light distributions on the light emitting surfaces, and a secondary optics system for reproducing the emitted light on a road in front of a motor vehicle as resulting total light distribution of the light module. The secondary optics system for reproducing the intermediate light distributions as resulting total light distribution of the light module is focused on at least one of the light-emitting surfaces of the collective lenses.

Light module for lighting equipment of a motor vehicle

A method for calculating the surfaces of optical lenses including the steps of: providing a desired light distribution to be generated with light passing through the lens; deforming a first surface of the lens to generate light source images of different sizes; deforming a second surface of the lens to displace the light source images such that they lie at their highest point directly at or on a light/dark border in a resulting light distribution; determining a quality of the resulting light distribution by a comparison with the predefined light distribution; if the quality lies above a predefined limit value, storing the calculated surfaces for the lens; otherwise, renewed deformation of the first surface; renewed deformation of the second surface; repeating the previous two steps until the quality of the resulting light distribution lies above the limit value; and storing the calculated surfaces for the lens.

The invention concerns a light module with a light source, a primary optical system and a reflector. The primary optical system contains a lens element that is embodied as a sector of an imaginary rotation body formed by the rotation of an imaginary rotation base surface around a rotation axis, wherein the rotation base surface is designed such that the lens element contains a light entry surface that faces the rotation axis and that surrounds the rotation axis and a light emitting surface that is located radially exterior to the rotation axis, wherein the reflector has at least one reflector zone that is embodied as a segment of the surface of a rotation symmetric imaginary associated circular cone, and wherein the axis of symmetry of the circular cone extends parallel to the rotation axis of the lens element.

Light module

The invention relates to an illumination comprised of an illumination source of electromagnetic radiation and a multi-part reflector () to route and focus the electromagnetic illumination, whereby the function of the separation (Y) from the angle (&#x3b2;) across at least partial areas of the reflector () is not a constant function.
