    摘要: An optical surface for softening a light/dark border of a lighting device for vehicles, having a grid of lens elements distributed over a base surface, by means of which a light bundle passing through the optical surface can be diffused in relation to a main direction, wherein the lens elements are each designed as micro-lens elements, which, on one hand, exhibit a central main emission surface, which follows a contour of the base surface, by means of which the light beams of the light bundle are deflected in a main direction corresponding to the contour of the base surface, and on the other hand, exhibit subsidiary emission surfaces, running at an angle to the central main emission surface, by means of which light beams of the light bundle are diffused in a diffusion direction in relation to the main direction.

    摘要: The invention relates to headlamps for vehicles comprising a number of semiconductor-based light sources being arranged on a substrate, and comprising an optical unit having at least one lens with a lens face for the generation of a given light distribution, wherein the lens face can be calculated by means of a lens equation, which is formed by means of a conic section equation completed by a deformation parameter, so that the lens face is determined with a deviation from a conic section shape, wherein a first deformation parameter for the change of the lens face according to differing degrees of shape change in the direction of the optical axis and vertically to the optical axis are given on one hand and that a second deformation parameter for the change of the lens face according to identical degrees of shape change in the direction of the optical axis and vertically to the optical axis are given on the other hand.

    摘要: A lighting device for vehicles with a multitude of light modules, each comprising a light source arranged on a substrate and a lens arranged at a distance to the light source for the creation of a given light distribution. A fixed side light module and a fixed main light module are provided as a light module. The side light module has an asymmetric lens, so that a light beam radiated by the side light module creates a side light distribution extending a main light distribution created by the main light module in the lateral direction.

    摘要: A headlamp for vehicles having numerous groups of LED light sources and having numerous optical units with different projection characteristics, such that a first light spot projected by a first optical unit is of a different size than a second light spot projected by a second optical unit, wherein a first subsidiary light distribution is formed by the first light spots, and a second subsidiary light distribution is formed by the second light spots, and the groups of LED light sources can be activated such that a predefined overall light distribution is formed by superimposing the subsidiary light distributions, wherein the optical units are designed such that all light spots have the same width, and the light spots projected by the various optical units have different heights.

    摘要: The invention relates to a method for controlling a light distribution of a headlamp, wherein the headlamp has at least one light-emitting element, wherein the at least one light-emitting element is individually drivable in order to generate an individual luminous flux, wherein the light emitted by the at least one light-emitting element has a light distribution, wherein the light distribution is defined by means of a predefined, three-dimensional basic distribution on the basis of parameters, wherein an adapted light distribution is varied on the basis of the basic distribution using selected, changed parameters.
