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.
