Patent number: 11421846Abstract: High beam headlight that can be produced with a small installation length with high efficiency and also provide effective low-cost manufacturability are described. For this purpose, a light source array having a plurality of light sources is combined with a honeycomb condenser. A collimator connected between the honeycomb condenser and the light source array illuminates the honeycomb condenser with collimated light of the plurality of light sources of the light source array. The arrangement of the components is such that the collimated light from a first light source leads to crosstalk-free irradiation of the honeycomb condenser and illumination of a first far-field segment. For each of the at least one second light source of the light source array, the collimated light of the respective second light source leads to irradiation of the honeycomb condenser with channel crosstalk and an illumination of a second far-field segment oriented obliquely with the first far-field segment.Type: GrantFiled: March 25, 2021Date of Patent: August 23, 2022Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Peter Schreiber, Chen Li, Dirk Michaelis, Christoph Wächter, Stephanie Fischer
