Patent number: 11563286Abstract: A lighting device contains a first circuit board and a second circuit board. The first circuit board has one or more connecting sections having overall at least two contact areas. The second circuit board has an opening through which the connecting section of the first circuit board can extend. At least two contact elements, which are electrically connected to conductive tracks of the second circuit board, are arranged on the second circuit board. Each contact element has a contact region by which the contact element butts against one of the contact areas of the first circuit board. As a result, an electrical connection is produced between the two circuit boards.Type: GrantFiled: January 24, 2019Date of Patent: January 24, 2023Assignee: LEDVANCE GMBHInventors: Klaus Eckert, Markus Hofmann, Thomas Klafta, Andreas Lovich, Henrike Streppel, Steffen Tegethoff, Marcel Vuc

Patent number: 10741946Abstract: A tube used for producing an electrically conductive connection between an electrical conducting element and a printed circuit board of a light fixture. The use of the tube in the printed circuit board makes it possible, due to a corresponding configuration and a region which widens in relation to the longitudinal direction, that the tube can be connected to the printed circuit board or is held thereby and can be soldered. Additionally, the configuration or widened portion prevents soldering agent from penetrating into the tube, so that a wire for voltage supply can then be introduced into the tube and can be connected thereto by deformation. As a result, an automatic and reliable method is made possible, so that a cost saving is produced.Type: GrantFiled: July 11, 2018Date of Patent: August 11, 2020Assignee: LEDVANCE GMBHInventors: Anton Joerg, Matthias Kellner, Thomas Klafta, Wolfgang Seitz, Christoph Steidl, Marcel Vuc
