Patent number: 11359784Abstract: A lighting device for a motor vehicle, in particular a headlamp, comprising at least two, preferably three, light sources, from which light emanates during the operation of the lighting device, the light of each of the light sources differing from that of the other light sources with regard to its wavelength spectrum, comprising modulator, which bring about a modulation of the light emanating from the light sources during the operation of the lighting device, so that information is transmitted by the light, the lighting device having a mixer for mixing the light emanating from the individual light sources, so that white light emerges from the lighting device during the operation of the lighting device.Type: GrantFiled: April 13, 2020Date of Patent: June 14, 2022Assignee: Hella GmbH & Co. KGaAInventors: Mathias Drueppel, David Duhme, Kai Ehlert, Bernd Fischer, Julien Hansen, Marc Kaup, Lukas Poertner, Claas Tebruegge, Benjamin Willeke, Jan-Henning Willrodt

Patent number: 11254256Abstract: A method for detecting misadjustments of a headlamp of a vehicle and to a device for this purpose. It is provided that the vehicle is provided with a detector with which at least one light signal of another road user is detected, and wherein the vehicle is equipped with a control unit with which light signal information of the detector is captured and by means of which adjustment information for correcting the misadjustment of the headlamp is output as a function of the captured light signal information.Type: GrantFiled: December 14, 2018Date of Patent: February 22, 2022Assignee: Hella GmbH & Co. KGaAInventors: Mathias Drueppel, David Duhme, Kai Ehlert, Bernd Fischer, Julien Hansen, Marc Kaup, Lukas Poertner, Claas Tebruegge, Benjamin Willeke, Jan-Henning Willrodt

Patent number: 10948153Abstract: A lighting apparatus for an automated or partially automated vehicle, having a light module, which contains a light source unit having a number of light sources and an optical unit assigned to the light source unit for generating a light signal, a surroundings sensor unit for detecting road users in surroundings of the vehicle, a control unit for controlling the light module, so that the light module generates the light signal as a function of the road users detected by the surroundings sensor unit and/or a relative position thereof with respect to the vehicle, the light module being positioned in a defined location of the vehicle and being designed in such a way that the light signal may be radiated at different horizontal and/or vertical spatial angles.Type: GrantFiled: January 15, 2020Date of Patent: March 16, 2021Assignee: Hella GmbH & Co. KGaAInventors: Bernd Fischer, Marc Kaup, Diana Mundt, Benjamin Willeke, Jan-Henning Willrodt

Publication number: 20200263847Abstract: Communications system for motor vehicles are provided, that comprise a plurality of transmission devices and a plurality of receiver devices where the transmission devices, individually or together, feature several light sources that are able to emit at least light with a first wavelength spectrum and light with a second wavelength spectrum. The transmission devices feature means of modulation that can effect modulation of the light such that information can be transmitted via the light. Receiver devices can capture the emitted light and extract the information from the captured light. The communications system is designed in such a way that the light with the first wavelength spectrum is used for the transmission of information in a first category and the light with the second wavelength spectrum is used for the transmission of information in a second category.Type: ApplicationFiled: October 2, 2018Publication date: August 20, 2020Inventors: Mathias Drüppel, David Duhme, Kai Ehlert, Bernd Fischer, Julien Hansen, Marc Kaup, Lukas Pörtner, Claas Tebrügge, Benjamin Willeke, Jan-Henning Willrodt
