Publication number: 20240302017Abstract: An illumination apparatus for a motor vehicle, the illumination apparatus having a printed circuit board having a plurality of light-emitting diodes arranged thereon. An optical lens plate and a reflector element are provided with the reflector element being arranged between the printed circuit board and the optical lens plate. The reflector element has a plurality of segments into which the reflector element is divided, and each light-emitting diode is associated with a segment so that light emitted from the light-emitting diodes is reflected at the reflector element and passes through the optical lens plate.Type: ApplicationFiled: May 15, 2024Publication date: September 12, 2024Applicant: HELLA GmbH & Co.

Patent number: 11402734Abstract: A multi-lens array is provided for a luminous source of a vehicle. The array includes at least one light source and multiple lens arrangements. Each lens arrangement includes a condenser lens and a projector lens as optical elements. The at least one light source is enabled to expose each of the multiple lens arrangements with light, and the projections of the multiple lens arrangements of this light interfere to form a single projected image.Type: GrantFiled: May 23, 2018Date of Patent: August 2, 2022Assignee: Hella GmbH & Co. KGaAInventors: Stefan Gröne, Michael Kleinkes

Patent number: 10124717Abstract: A customizable modular lamp is made up of an outer lens customized by known per se techniques, which covers a housing provided with at least one recess in which is mounted a customizable module consisting of a retro-reflective lens under which there is an inner customized lens personalized by known per se techniques, under which there is a printed circuit board with LEDs that is held in a holder fastened to a cover provided with at least one element for ventilation. During the daylight, personalization is visible on the outer customized lens. In the darkness and—depending on the recipient's request—when activating the lights for changing direction, position or braking, customization becomes evident by lighting inside the lamp, on the surface of the inner customized lens.Type: GrantFiled: June 5, 2015Date of Patent: November 13, 2018Assignee: Hella GmbH & Co.
