Problems solved by technology

[0004] However, what is problematic in these lighting devices is the electrical connection of the circuit boards to each other
Especially in metal core boards, the connection is actually possible by means of SMD (Surface Mount Device) plug-in connectors or by direct soldering of cables, which entails high manufacturing outlay and multiple components have to be provided

Embodiment Construction

[0029] figure 1 A plug connection element 1 according to the invention is shown with a press-fit plug 2 and a pin-shaped part 3 facing away from the press-fit plug 2 , which is surrounded on all sides by an electrically insulating encapsulation 4 . The polyamide material PA 6 is used as insulating material for the encapsulation of the plug connection elements, but other materials are also common to those skilled in the art, depending on requirements.

[0030] Fastened to the part 3 facing away from the press-fit plug 2 are two connecting wires 5 which serve as solder terminals for electrically contacting the plug-in connection element 1 with the first printed circuit board 6 . The cylindrical plug-in connection element 1 is flattened in the region of the press-fit plug 2 , that is to say the cross-section narrows in one direction and widens in a direction running perpendicular to this direction. In this flattened part there is an opening 7 . At the tip, the press-fit plug 2 ...

Abstract

The invention relates to an illumination device (9) comprising at least one light source, in particular at least one light-emitting diode (LED) (11a), and also at least two printed circuit boards (6, 10) which are arranged at least in part one above another and preferably approximately parallel. According to the invention, the at least two printed circuit boards (6, 10) are connected by means of at least one plug connection element (1), wherein the plug connection element (1) is embodied as an interference-fit plug (2) on at least one side.

Description

technical field [0001] The invention relates to a lighting device comprising at least one light source, in particular at least one light emitting diode (LED), and at least two circuit boards arranged at least partially one above the other and preferably approximately parallel. The invention likewise relates to a method for producing such a lighting device. Background technique [0002] Lighting devices, in particular such lighting devices having at least one light emitting diode (LED), often comprise a plurality of circuit boards on which the electronics required to operate the lighting device are arranged. In the case of lighting devices equipped with LEDs, the light-emitting diodes themselves are often also arranged thereon. [0003] Since LEDs and other electronic components generate a great deal of heat during operation, these components are preferably arranged on a circuit board which conducts heat well, such as a metal core board, while the other components are applie...
