A motor vehicle headlamp includes numerous semiconductor light sources disposed in a matrix, which can be activated individually for emitting light, numerous primary lenses disposed in a matrix, allocated to the semiconductor light sources, for bundling the light emitted by the semiconductor light sources and for generating a primary light distribution on light exit surfaces of the primary lenses, and a shared secondary lens for projecting the primary light distributions as secondary light distributions onto a roadway in front of the motor vehicle, such that the secondary light distributions illuminate a high-beam region. To reduce the structural height of the secondary lens without losses in terms of efficiency, the motor vehicle headlamp includes a cylindrical lens having a cylinder axis disposed in the beam path of the light module between the primary lenses and the secondary lens that is oriented such that it is substantially horizontal.

The present invention is directed toward light module for a motor vehicle headlamp that has numerous light sources, a primary lens, and a secondary lens. The primary lens is configured to collect light emitted from the light sources, and to convert this light to an intermediate light distribution having the form of a closed, illuminating surface area. The secondary lens has an object-side focal length, and the primary lens and the secondary lens are disposed such that the intermediate light distribution lies, at a spacing of this focal length, in the beam path in front of the secondary lens. The light emission surfaces of the light sources are separated from one another by spacings lying between them, and the primary lens is configured to distribute the light emitted from the light sources such that the spacings in the intermediate light distribution can no longer be perceived.

A light module of a lighting device comprises one passing-light sub-module for production of a dimmed-light distribution below a horizontal 'light/dark' boundary, one high-beam sub-module for production of a light distribution above the boundary, a common projection-lens system for production of an overall light distribution, and one element deflecting a course of light beams of the sub-module(s) before it falls on the system. To realize the smallest system and a reduction of non-homogeneities in the overall light distribution in a region of the boundary, a majority of the light beams of the high-beam sub-module falls on a common segment of the system as a majority of the light beams of the passing-light sub-module, a smaller portion of the light beams of the high-beam sub-module falls on another segment of the system, and the system exhibits a deflector that deflects at least a portion of the light beams falling on the other segment downward.

A reflector maps the light-emitting surface without generating an actual intermediate image in front of the lamp module and defines at least two reflecting and strip-shaped facets longitudinal axes of which are more parallel rather than transversal to the longitudinal edge of the light-emitting surface and disposed at a spacing to the light source where the light-emitting surface is mapped with the same mapping scale in front of the lamp module such that the light-emitting surface is mapped with a longitudinal edge running horizontally and another edge running vertically.

Lamp module for a glare-free motor vehicle high beam

The invention relates to a projection module for a headlight. The module generates light distributions with light sources switchable independently. In order to generate a first distribution, light from a first group is coupled into an optical element in the beam path. The optical element has a reflecting underside having a contour corresponding to the bright-dark boundary. The light coupled out from the optical element is projected by a lens for generating the first distribution. A further light group is additionally activated in order to generate a second distribution. The light emitted by this group illuminates a region of the light distribution above the bright-dark boundary. Part of the light from this group is coupled into the optical element, mixes there with the light from the first group and is then coupled out together to generate an unsharp bright-dark boundary.

The invention relates to a light module () for a lighting device for a motor vehicle. The lighting module () comprises a light source () for emission of electromagnetic radiation, preferably in the form of light which is visible for the human eye, and a reflector () for focusing the emitted radiation.

A reflector neck () is formed on the reflector (), surrounding at least a part of the holding opening (), to which reflector neck () another part () of the light source () is attached.

The lamp () can therefore be replaced more easily, and in less space.
