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. An 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 selectively contacting a respective LED lamp or an electrical jumper, 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, wherein the connection points are formed as respective contacts on both sides of a conductor disruption,

wherein the connection points of a conductor not contacted by an LED lamp are bridgeable by means of the electrical jumper,

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, and

wherein at least two supply lines are arranged on the same substrate.

2. The LED system according to claim 1, wherein the connection points are formed as respective contacts on both sides of a supply line.

4. The LED system according to claim 1, wherein the two supply lines are arranged in parallel on the same substrate.

5. The LED system according to claim 1, wherein the two supply lines are lines of a common bus system.

6. The LED system according to claim 1, wherein the two supply lines are being tapped into different electrical potentials.

7. The LED system according to claim 1, wherein only a first of the two supply lines comprises the multiple connection points.

8. The LED system according to claim 7, wherein the multiple connection points each comprise two juniper pins and wherein a second of the two supply lines comprises several single/non-bridging jumper pins.

9. The LED system according to claim 8, wherein the two supply lines are connected by an end piece which end piece bridges the two jumper pins of one connection point of the first supply line as well as one of the two jumper pins of the one connection point and one single jumper pin of the second supply line.

3. 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 electrical connecting member comprises multiple connection points for selectively contacting a respective LED lamp or an electrical jumper, and wherein the method comprises the following steps:

selecting a connection position for an LED lamp on the electrical connecting member;

and connecting an LED lamp at the selected connection position on the electrical connecting member,

wherein the electrical connecting member comprises a circuit board with an electrical conductor formed thereon,

wherein the connection points are formed as contacts on the at least one electrical conductor and the step of selecting a connection position for an LED lamp at the electrical connecting member comprises selecting one of multiple predefined connection points,

further comprising the step of;

bridging of open connection points not connected to LED lamps by an electrical jumper,

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, and
