Publication number: 20240093852Abstract: A headlight for a motor vehicle having at least one light source which emits light during operation of the headlight. A primary optical system has at least one light entry surface for the light emitted by the at least one light source and at least one light exit surface. A secondary optical system, which, during operation of the headlight, projects the light emitted from the at least one light exit surface of the primary optical system into the space outside the motor vehicle where it produces a light distribution which has a horizontal cut-off line and light portions located above the cut-off line in order to implement an OS function (overhead sign function). The headlight being designed such that a portion of the light emitted by the primary optical system is reflected back to the primary optical system by the secondary optical system.Type: ApplicationFiled: November 27, 2023Publication date: March 21, 2024Applicant: HELLA GmbH & Co. KGaAInventors: Bjoern DRESSLER, Ronny LETZIN, Fabian SCHUELER

Publication number: 20230014251Abstract: A head lamp module for a motor vehicle is provided, and includes one single printed circuit board, a first group of light sources, a second group of light sources, a lens and an optical device. The first group of light sources and the second group of light sources are both arranged on the printed circuit board. The first group of light sources and the second group of light sources emit light to the optical device. The optical device is adapted to guide the emitted light in a direction towards the lens. The light leaves the head lamp module through the lens.Type: ApplicationFiled: September 26, 2022Publication date: January 19, 2023Inventors: David Brunne, Björn Dressler, Ronny Letzin

Patent number: 9719646Abstract: 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.Type: GrantFiled: July 24, 2014Date of Patent: August 1, 2017Assignee: Hella KGaA Hueck & Co.Inventors: Dmitry Fedosik, Bernd Giepen, Matthias Knoche, Ronny Letzin, Ralf Spiekermann
