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.

Lighting device with plug connection for electrical connection of two circuit boards

A lighting device (in particular an MR-16 or a PAR-16 lamp) comprises a housing and a lens. A light module having a light source and a driver is attached to the lens. The lens is connected to the housing by means of a snap-on connection or by means of a formed (thermally, for example) edge section.

Lighting device with lens

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.

Connection of an electrical conducting element to a printed circuit board of a light fixture

A light module serves for inserting into a housing of a semiconductor lamp and comprises: a driver (), a cooling element, a light generator, abutting the cooling element, with at least one semiconductor light source, which is electrically connected with the driver, and an optical refraction element covering the at least one semiconductor light source, wherein the refraction element is fastened on the cooling element and presses the light generator onto the cooling element. A semiconductor lamp comprises a housing open at the front into which the light module is inserted from the front side and on which the light module is fastened. A method serves for producing a semiconductor lamp, wherein at least the driver, the cooling element, the light generator and the refraction element are assembled into an individually manageable light module and the light module is then inserted into a housing. The invention is also applicable to replacement or retrofit lamps, in particular with a pin base, particularly a bipin base, e.g. to retrofit lamps for replacing halogen lamps, for example of the type MR16.

Light module

A lighting device and the method of creating the lighting device having a lighting module and a lens mechanically connected to that lighting module. The lens has one or more connecting pins. The light module has one or more receiving openings for receiving the connecting pins. The free ends of the connecting pins are deformed by thermal deformation so that the light module is held on the lens.
