摘要： A lighting device for a vehicle, in particular headlights for a vehicle, having a plurality of light sources, from which light is emitted during operation of the lighting device, projection optics for projecting the light, and a generator for generating a light distribution in the exterior of the vehicle, which has a soft transition in the vertical direction from a central region to the near field and/or the far field of the light distribution. The generator has a plurality of converters which change the wavelength spectrum of the light emitted from the light sources. The lighting device being designed in such a way that during operation of the lighting device, at least one first region of at least one of the converters is subjected to a greater luminous flux density of the light emitted from the light sources as a second region of the at least one converter.

摘要： A quality testing method is provided for a light source in a headlamp, in which the light source contains a matrix of light pixels that can be controlled individually. The light pixels are activated individually according to a test procedure, such that the light source emits light corresponding to a test pattern. The test pattern is recorded by an optical recorder, and the test pattern is compared with a reference pattern with regard to brightness and/or color value.
