A motor vehicle headlight includes a light module, having a light source, a primary optics that collects light and micro projectors, of which each one comprises one respective input lens, one respective output lens and an aperture that is arranged between the input lens and the output lens. The input lens, the aperture and the output lens feature one width and one height. The primary optics, the input lens, the aperture and the output lens of one respective micro projector are arranged in such a way, that the light from the light source that emits from the primary optics illuminates the input lens, and the light of the light source that emits from the input lens illuminates the output lens. The headlight includes micro projectors, whose widths (b) are different and whose heights (h) are different.

Motor vehicle headlight with a light module featuring a micro projector

A headlight of a motor vehicle including a light source and first projection optics, in which each one includes a respective first pair made of one respective first image mask and of one respective first projection lens with a first focal length, which is illuminated by the light source through the one respective image mask. The headlight has two projection optics, in which each one is featuring a respective second pair made of one respective second image mask and of one respective second projection lens with a second focal length, which is illuminated by the light source through the one respective second image mask. The second focal length is greater than the first focal length. An illuminated portion of the first image mask, has a shape of at least a first portion of an overall light distribution of the headlight, and a portion of the second image masks, has a shape of a central portion of the overall light distribution of the headlight.

Headlight of a motor vehicle with low construction depth

Light guiding elements having a light guiding section extending between a light entrance surface for coupling in light and a light exit surface for coupling out light from the light guiding element through the light exit surface. The light exit surface extends along an exit surface longitudinal direction. The light guiding section has at least a first and a second lateral surface extending from the light entrance surface to the light exit surface such that light can be guided by total internal reflection from the light entrance surface to the light exit surface. The form of the light entrance surface differs from that of the light exit surface. The light guiding section has a roof section extending toward the light exit surface in which the first and the second lateral surfaces taper toward each other with respect to the exit surface longitudinal direction.

Light guiding element and light module

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

The invention relates to a projection lens for use in an LED module of a motor vehicle headlamp. The LED module has a light source in the form of an LED matrix including numerous LED chips disposed in a matrix adjacent to and/or above one another, a primary lens including numerous primary lens elements disposed in a matrix adjacent to and/or above one another for bundling light emitted from the light source, and a projection lens. The projection lens projects a light exit surface of the primary lens to generate a predefined light distribution on a surface in front of the vehicle. The projection lens is designed such that it generates at least two separate images of the light exit surface of the primary lens on its image side, which are offset to one another in the horizontal direction.

A light module for a motor vehicle headlamp having an optical fiber configuration with at least one first optical fiber branch and one second optical fiber branch. Each of the two branches has a light exit surface each bordered by two narrow sides and disposed such that a narrow side of the first branch is disposed parallel and directly adjacent to a narrow side of the light exit surface of the second branch. Each branch exhibits two transport surfaces. The transport surfaces exhibit surface norms having a directional component, which faces more toward a first narrow side of the two narrow sides of the branch than toward a second narrow side of the two narrow sides of the branch, wherein the narrow sides lying directly adjacent and parallel to one another are a second narrow side of the first branch and a first narrow side of the second branch.

Light module for a motor vehicle headlamp, configured to generate a stripe-shaped light distribution

A light module of a motor vehicle generates a spot distribution of a high-beam-light distribution formed by superimposition of the spot distribution and a base distribution generated by at least one other module. The light module comprises a plurality of separately controllable sub-modules that generate a plurality of stripe-shaped segments of the spot distribution that supplement it. Also, a headlight generates the high-beam-light distribution and comprises the light module. Furthermore, a headlight system comprises a pair of the headlights disposed in a front region toward sides of the vehicle and each of which generates the high-beam-light distribution. The headlights include corresponding light modules that generate stripe-shaped segments of left and right sides, respectively, of the spot distribution such that the stripe-shaped segments of the light modules of the headlights supplement the spot distribution or are at least partially superimposed thereon.
