A lens for a headlamp, the lens being at least partially formed from at least one plastic, having a lens surface and an edge surrounding the lens surface, from which at least one fastening element for fastening to a lens holder of the headlamp extends away from the lens surface, the at least one fastening element being designed as a fastening fork having two spaced-apart elastic fastening prongs. A lens system is also provided having a lens of this type and a lens holder, the lens holder having recesses corresponding to the fastening prongs, and the fastening prongs being elastically positioned by their outsides on outer insides of the recesses, or the fastening prongs being elastically positioned by their insides on inner insides of the recesses, so that the lens is fastened to the lens holder without play.

Lens, lens system, headlight and motor vehicle

A headlamp for vehicles having a projection module containing a first light source for generating a first light bundle, a reflector assigned to the first light source, a lens, and an edge disposed in a focal plane for generating a low beam light distribution. The headlamp also includes a second light source for generating a second light bundle and an optics unit disposed between the lens and the second light source for generating a supplementary light distribution, such that by superimposing the supplementary light distribution and the low beam light distribution, a high beam light distribution is formed. The optics unit is formed by a flat waveguide having a light entry surface for receiving the second light bundle emitted from the second light source. The second light source is disposed in the proximity of the light entry surface, having a light exit surface, and flat sides extending between the light entry surface and the light exit surface, on which entering light can be conducted through total reflection. A light/dark border of the low beam light distribution is formed by the edge of the flat waveguide formed as the front outer edge, which connects the light exit surface and an upper flat side of the waveguide. The upper flat side of the flat waveguide is provided with a light blocking coating, such that an entry of light beams from the first light bundle striking the upper flat side is prevented.
