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.

Patent number: 11395394Abstract: An illumination device having a first and second light module each having a light source and an optical unit for generating a first illumination region and a second illumination region, respectively. A control unit controls the first light module and the second light module, so that a larger number of light pixels are imaged in the first illumination region than in the second illumination region with respect to a surface of equal size, wherein the light pixels of the first light module have a greater illumination intensity than the light pixels of the second light module. The control unit acts upon the light sources of the first light module or the second light module such that the light sources of the first and second light module are each operated with a thermal output within a tolerance band and below a maximum thermal output of the at least one light source.Type: GrantFiled: May 28, 2021Date of Patent: July 19, 2022Assignee: Hella GmbH & Co.

Patent number: 11197358Abstract: A method for reducing the maximum demand of the current received by an LED matrix from a current source. Each LED of the LED matrix receiving a pulse width-modulated current from the current source, an activation period being assigned to each LED in an elementary period of the pulse width-modulated current, and/or a deactivation period is assigned, in which no current flows through the LED, the activation period and the deactivation period being able to be equal in length or shorter than the elementary period, and in the case that the activation period assigned to one of the LEDs and the deactivation period assigned to this LED are shorter than an elementary period, the activation period begins at an activation point in time and ends at a deactivation point in time, and the deactivation period begins at the deactivation point in time and ends at the activation point in time.Type: GrantFiled: February 14, 2020Date of Patent: December 7, 2021Assignee: Hella GmbH & Co.

Patent number: 11014488Abstract: A procedure is provided for actuating at least one light module of the light unit of a vehicle with a plurality of light sources and a light control system automatically actuating the light module. At least two first light distribution arrangements are generated and first data sets corresponding to the first light distribution arrangements are stored in a memory of the light control system. In order to implement a plurality of light distribution arrangements with less effort, at least one second light distribution arrangement is allocated to at least one pairing of two of the at least two first light distribution arrangements, and actuation of the light module for generating this at least one second light distribution arrangement is performed depending on the first datasets of the assigned pairing from the first light distribution arrangements.Type: GrantFiled: August 7, 2018Date of Patent: May 25, 2021Assignee: Hella GmbH & Co.

Patent number: 8723948Abstract: A system for producing a light beam in the front area of a vehicle includes a headlamp with an LED array, a device for detecting objects in the area, a device for determining the position of a detected object relative to the vehicle. The light beam produced by the array has a horizontal illuminance distribution wherein the horizontal angles of the contributions of at least two LEDs to the illuminance distribution overlap at least partially, each illuminance being selectively varied for different positions in front of the vehicle and different horizontal angles relative to a reference direction. Depending on the detected object's position to the vehicle and an object width, a glare-critical horizontal angle range is determined, and the individual LEDs arc controlled, under consideration of how much the horizontal angle ranges of their contributions to the illuminance distribution overlap, such that an illuminance limit value is not exceeded.Type: GrantFiled: August 12, 2008Date of Patent: May 13, 2014Assignee: Hella KGAA Hueck & Co.Inventors: Micro Götz, Susanne Hagedorn, Christian Hüster, Alexander Kornek, Wolfgang Menk, Jacek Roslak, Rafael Giebl
