Abstract

The LED system has a set consisting of multiple LED lamps and an integrally formed electrical connecting member common to the LED lamps, wherein the electrical connecting member has multiple connection points for contacting a respective LED lamp.

Claims

1. A LED system with a set consisting of multiple LED lamps and an integrally formed electrical connecting member common to the LED lamps, wherein the electrical connecting member comprises multiple connection points for contacting a respective LED lamp.

2. The LED system according to claim 1, wherein the electrical connecting member comprises a wire lead and at least one LED lamp comprises a disconnect/contacting connection for connecting the wire lead.

3. The LED system according to claim 2, wherein the wire lead is a ribbon cable.

4. The LED system according to claim 2, wherein the disconnect/contacting connection is a crimp/cut connection.

5. The LED system according to claim 4, wherein the crimp/cut connection comprises a disconnecting member for disconnecting a conductor of the wire lead and two contact clamps arranged on both sides thereof for contacting the disconnected conductor.

6. The LED system according to claim 5, wherein the crimp/cut connection is formed for connecting to a supply line of the wire lead.

7. The LED system according to claim 2, further comprising at least one end piece with a crimp connection for connecting two supply lines of the wire lead.

8. The LED system according to claim 1, wherein the electrical connecting member comprises at least one electrical conductor formed on a circuit board, wherein the connection points are formed as contacts on the at least one electrical conductor.

9. The LED system according to claim 8, wherein the connection points are formed as respective contacts on both sides of a conductor disruption.

10. The LED system according to claim 8, wherein the connection points are formed as respective contacts on both sides of a supply line.

11. The LED system according to claim 9, wherein connection points of a conductor not contacted by a LED lamp are bridgeable by means of a electrical jumper.

12. The LED system according to claim 9, wherein the connection points are positioned in a supply line and the LED system comprises a further supply line, wherein an end piece connects the two supply lines.

13. A LED lamp, comprising a disconnect/contacting connection for connecting to a wire lead.

14. The LED lamp according to claim 13, wherein the disconnect/contacting connection is a crimp/cut connection.

15. The LED lamp according to claim 13, wherein the wire lead is a ribbon cable.

16. The LED lamp according to claim 14, wherein the crimp/cut connection comprises a disconnecting member for disconnecting at least one conductor of the wire lead and two contact clamps arranged on both sides thereof for contacting the disconnected conductor.

17. A method for assembling an LED system or an LED chain, comprising at least one integrally formed electrical connecting member and multiple LED lamps, wherein the method comprises the following steps:
