Abstract:
A headlight module with a minimum of one LED for generating a low beam and with a minimum of one LED for generating a high beam. An optical element is provided into which light from the minimum of one LED for generating the high beam can be emitted. The optical element is arranged as a cover for a portion of the light that can be generated by the LED for generating a low beam. The optical element features a decoupling surface that at least partially includes a surface structure with a composition such that, in the area of the surface structure, light is emitted that can be decoupled from the optical element.
