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 headlight for VEHICLES with a plurality of LED light sources that are arranged in a matrix in an LED array, each emitting a partial light beam that falls on an optical unit, located in the front, in the main beam direction in order to image light spots that combine to form a predetermined light distribution, whereby the optical unit comprises a first lens element and a rotationally symmetrically arranged second lens element, by means of which the partial light beams are transformed so that imaged light spots that are adjacent in the light distribution are directly adjacent or overlap, wherein the first lens element (4) is shaped in such a way that light spots of the light distribution in the vertical direction have a greater separation than in the horizontal direction.
