Abstract
An optical system for use in a headlamp of a motor vehicle includes condenser optics formed by a condenser lens matrix and being provided to focus incoming light beams. It further includes at least one reflective shield being provided to reflect at least a subset of the focused light beams and to create a cut-off line of outgoing light beams. It further includes imaging optics formed by an imaging lens matrix, which is provided to project the focused light beams and the reflected light beams in front of the headlamp, such that the reflected light beams contribute to an intensity hotspot on one side of the cut-off line.

An optical system for use in a headlamp of a motor vehicle, comprising:
- condenser optics formed by a condenser lens matrix and being provided to focus incoming light beams;
- a plurality of reflective shields being provided to reflect at least a subset of the focused light beams and to create a cut-off line of outgoing light beams;
- and
- imaging optics formed by an imaging lens matrix and being provided to project the focused light beams and the reflected light beams in front of the headlamp such that the reflected light beams contribute to an intensity hotspot on one side of the cut-off line, wherein
- at least one of the plurality of reflective shields comprises a kink at an edge facing the imaging optics.
The optical system according to 3, further comprising at least one absorbing shield arranged between the condenser optics and the imaging optics, the at least one absorbing shield being provided to prevent crosstalk between the channels of light beams.
