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.

Abstract: A lamp includes a base with at least two electrical connecting elements. A bulb is rotatably mounted relative to the base. A light engine is arranged in the bulb with at least one light-emitting element and an electrically conductive substrate on which the light-emitting element is arranged. An electronic driver is connected to the electrically conductive substrate for activation of the light-emitting element. The base has a base sleeve in which the electronic driver is arranged. The electrically conductive substrate has a flexible connecting section between the electronic driver and the light-emitting element.
