  • Patent number: 11563286
    Abstract: 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.

  • Patent number: 10741946
    Abstract: 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.
