1-67. (canceled)
A vehicle headlight, the vehicle headlight comprising an integrally configured headlight lens having:
- a first region configured as one of the group (a) freeform lens part and (b) part of an aspherical lens;
- and
- at least a second region arranged below the first region and configured as part of a Fresnel lens.
A vehicle headlight, the vehicle headlight comprising an integrally configured headlight lens having an integral lens body composed of glass, the integral lens body comprising:
- a first region;
- at least a second region arranged below the first region;
- a surface facing the light source;
- and
- a surface facing away from the light source, the surface facing away from the light source running substantially continuously in the first region, and the surface facing away from the light source comprising in the second region at least three segments separated from one another by a step.
A vehicle headlight lens comprising:
- a first region configured as one of the group (a) freeform lens part and (b) part of an aspherical lens;
- at least a second region configured as part of a Fresnel lens;
- and
- a transition area between the first region and the second region being inclined approximately between 1° and 20° relative to an optical axis of the headlight lens.
A vehicle headlight lens having an integral lens body composed of glass, the integral lens body comprising:
- a first region;
- at least a second region;
- a surface facing the light source;
- a surface facing away from the light source, the surface facing away from the light source running substantially continuously in the first region, and the surface facing away from the light source comprising in the second region at least two segments separated from one another by a step;
- and
- a transition area between the first region and the second region being inclined approximately between 1° and 20° relative to an optical axis of the headlight lens.
An integrally configured vehicle headlight lens comprising:
- a first region configured as one of the group (a) freeform lens part and (b) part of an aspherical lens;
- at least a second region configured as part of a Fresnel lens;
- and
- a separation between the first region and the second region running essentially through an optical axis of the headlight lens.
An integrally configured vehicle headlight lens comprising:
- a first region configured as one of the group (a) freeform lens part and (b) part of an aspherical lens;
- and
- at least a second region configured as part of a Fresnel lens, the second region having substantially the same focal point as the first region.
