Method for contacting a lighting device and connection element for attachment on a lighting device

1. A method for contacting a lighting device, wherein the lighting device has a circuit board which is covered at least partly by a sealing compound layer; wherein the lighting device can be separated at a separating point into two lighting device sections and each of the lighting device sections, adjacent to the separating point, has at least one electrical contact; wherein the method comprises:

removing at least portions of the sealing compound layer on both sides of the separation point above the electrical contacts of the lighting device sections adjacent to the separating point so that the electrical contacts adjacent to the separating point remain covered by a thinner, remaining sealing compound layer;

separating the lighting device at the separation point into the two lighting device sections; and

attaching a connection element at least to the remaining sealing compound layer of at least one of the lighting device sections,

wherein the connection element has at least one contacting element, which contacts a respective contact covered by the remaining sealing compound layer after a separation or penetration of the remaining sealing compound layer.

2. The method as claimed in claim 1 , wherein at least the sealing compound layer is cut into by means of two essentially vertical cuts on both sides of the separation point above the contacts and at least between the vertical cuts is additionally separated by means of at least one horizontal cut at a height above the contacts.

3. The method as claimed in claim 1 , wherein the circuit board and the sealing compound layer are accommodated in a profile and at least a part of the profile is removed on both sides of the separation point together with the sealing compound layer.

4. The method as claimed in claim 1 , wherein the connection element is placed at least on a part of the remaining sealing compound layer and for an electrical connection to the contact separates or penetrates the remaining sealing compound layer located above the contact by means of a contacting element.

5. The method as claimed in claim 4 , wherein the contacting element has a cutting edge for separating or penetrating the remaining sealing compound layer.

6. The method as claimed in claim 4 , wherein the connection element is a plug-in connector.

7. The method as claimed in claim 6 , wherein the contacting element is located partly in a connector receptacle and at least during a first plugging in of a plug pin into the connector receptacle the contacting element is pushed by means of the plug pin through the remaining sealing compound layer down onto the contact.

8. The method as claimed in claim 1 , wherein the contacting element during an insertion movement of the plug-in connector is pressed through the remaining sealing compound layer down onto the contact.

9. The method as claimed in claim 8 , wherein the insertion movement of the connection element comprises a sliding movement.

10. The method as claimed in claim 8 , wherein the insertion movement of the connection element comprises a vertical insertion movement.

11. The method as claimed in claim 1 , wherein the circuit board is a strip-type circuit board.

12. The method as claimed in claim 11 , wherein the circuit board is a strip-type flexible circuit board.

13. The method as claimed in claim 1 , wherein the sealing compound material features an elastic base material.

14. The method as claimed in claim 13 , wherein the sealing compound material features silicon.
