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

Publication number: 20200208810Abstract: A method is provided for mounting a light module. A light module that is mounted by means of such a method includes at least one light source for emitting light, and at least one optical element for forming the beam of light. The relative arrangement between the light source and the optical element is adjusted via the following steps. The light module is arranged in an adjusting device, and a light detection device is provided. The light source is switched on, and the light detection device is illuminated with the light. A set deviation between a value and an actual value of a light field generated with the light as compared to a required light field is measured. The relative arrangement between the light source and the optical element is then adjusted until the set/actual deviation is minimal or zero.Type: ApplicationFiled: May 11, 2018Publication date: July 2, 2020Inventors: David Duhme, Werner Kosters, Stefan Kraus, Thomas Albert Röbbecke, Ralf Seiger
