Publication number: 20240125444Abstract: A lighting device for a motor vehicle, wherein the lighting device has a circuit board with a multiplicity of light-emitting diodes arranged thereon, a transparent optical layer, and a reflector element, wherein the reflector element is arranged between the circuit board and the optical layer, wherein the reflector element has multiple segments into which the reflector element is subdivided, wherein a segment is associated with each light-emitting diode so that light emitted by the light-emitting diodes can be reflected by the reflector element and can pass through the optical layer. Two light-emitting diodes are arranged in a segment. In addition, a lighting system and a motor vehicle are provided.Type: ApplicationFiled: October 14, 2023Publication date: April 18, 2024Applicant: HELLA GmbH & Co.

Publication number: 20230408054Abstract: A lighting device for a motor vehicle, having at least one light source, a planar light guide with an input surface and at least one output surface. The input surface is formed in particular as a front surface of the light guide. The lighting device is set up so that the light generated by the at least one light source enters the light guide at least partially through the input surface so that the light entering through the input surface exits at least partially from the at least one output surface and so that the light merging from the at least one output surface of the light guide passes at least partially through the at least one optical panel. At least one texturing is arranged on the at least one output surface of the light guide and/or the at least one optical panel.Type: ApplicationFiled: May 24, 2023Publication date: December 21, 2023Applicant: HELLA GmbH & Co.

Patent number: 11098871Abstract: A headlamp for vehicles comprising at least one light source for generating at least one light beam, a scanning device for one-dimensionally scanning the at least one light beam bidirectionally in a scanning direction, and an array of optical elements arranged side by side in a direction that corresponds to the scanning direction so that the at least one light beam impinges on the optical elements successively. At least some of the optical elements are designed to expand the at least one light beam in a direction perpendicular to the direction, in which the optical elements are arranged side by side.Type: GrantFiled: December 22, 2017Date of Patent: August 24, 2021Assignee: Hella GmbH & Co. KGaAInventors: Marcel Bursy, Markus Giehl, Julien Hansen, Marc Kaup, Thomas Rettweiler, Christian Schmidt, Christian Smarslik, Philip Stroop, Carsten Wilks, Benjamin Willeke

Patent number: 10421392Abstract: A lighting apparatus for vehicles with a light source unit and optical equipment for generating a specified signal light distribution to provide a specified signal function. The optical equipment consists of at least two optical units. A first optical unit deflects a first light beam emitted by the first light source is designed to generate the specified signal light distribution. A second optical unit, a hologram element, is used to deflect a second light beam generated by the second light source to create a holographic light image so that the specified signal function consists of the signal light distribution and the holographic light image that is spaced at a distance.Type: GrantFiled: February 9, 2016Date of Patent: September 24, 2019Assignee: Hella GmbH & Co.
