Patent number: 8342726Abstract: A vehicle headlamp includes a first light source, at least one second light source and an integrally designed, transparent shaped part. The shaped part includes a first optical structure for orienting light radiated by the first light source and at least one second optical structure for orienting light radiated by the second light source. The first optical structure and the second optical structure each have a continuously curved surface or a continuous, curved surface with an extent of at least in each case half a centimeter, in particular one centimeter, in two orthogonal directions.Type: GrantFiled: August 8, 2006Date of Patent: January 1, 2013Assignee: Docter Optics GmbHInventors: Jens Fischer, Steffen Holtz

Patent number: 7303319Abstract: The present invention relates to a headlight lens for a vehicle headlight having a light source, in particular for a motor vehicle headlight, as well as a vehicle headlight, in particular a motor vehicle headlight, having a light source and a headlight lens. The headlight lens including a lens body is made of a transparent material, which includes a surface to face the light source and a surface to face away from the light source. The headlight lens having an emblem, on the surface to face the light source, having a basal surface, which, with respect to the surface to face the light source or with respect to an optical axis of the headlight lens, is sloped in such a way that light entering into the lens body through the surface to face away from the light source parallel to the optical axis of the headlight lens is subject to a total reflection at the basal surface.Type: GrantFiled: March 7, 2005Date of Patent: December 4, 2007Assignee: Doctor Optics GmbHInventors: Steffen Holtz, Alois Willke

Patent number: 6598580Abstract: An insert filter 10 for cleaning a gas stream, particularly for the intake air of an internal combustion engine or an air-conditioning unit, which includes a filter frame 11, a filter element 12 placed in the filter frame 11, and a shaft cover 13 and which is placed in the shaft 14 of a duct system 15 that guides the gas stream such that an unfiltered side 16 is separated from a clean side 17 by the filter element 12 and the filter frame 11. The shaft cover 13 closes a shaft opening 24 through which the insert filter 10 is inserted in the shaft 14. The filter frame 11 is connected to the shaft cover 13 so that the filter frame 11 can be removed from the shaft 14 without any need for additional removal aids by simply pulling on the shaft cover 13.Type: GrantFiled: July 16, 2001Date of Patent: July 29, 2003Assignee: Filterwerk Mann & Hummel GmbHInventors: Christoph Baumann, Timo Dirnberger, Steffen Holtz, Daniel Hoppmann, Ulrich Huengsberg, Volker Hueppmeier, Hans-Juergen Isensee, Stefan Maier, Kai Mierau, Hans-Peter Scholl, Stefan Weiss
