Abstract
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.
