Abstract

A codable electronic circuit arrangement, in particular an LED circuit arrangement ( 1 ), having a lead ( 3 ), via which electronic circuit elements ( 6 ) of the circuit arrangement, in particular LED components, can be driven by a drive circuit ( 2; 20; 21; 22 ). The lead ( 3 ) has a plurality of coding conductors ( 3 c , 3 d ), which carry a code via a combination of electrically interrupted and electrically continuous coding conductors ( 3 c , 3 d ), wherein the code gives an indication of specific properties of the circuit arrangement.

Claims (17)

1. An electronic LED circuit arrangement, comprising:

a lead, via which electronic circuit elements of the LED circuit arrangement comprising LED components are drivable by a drive circuit; and

an evaluation circuit located in the LED circuit arrangement, the evaluation circuit being a digital/analog converter comprising a resistor network;

wherein the lead has a plurality of coding conductors, which carry a code by means of a combination of electrically interrupted and electrically continuous coding conductors, said code giving an indication of specific properties of the LED circuit arrangement; and

wherein said evaluation circuit is adapted to detect said code, and a reference voltage (Uref) of the digital/analog converter (D/A) is a measurement voltage provided by a measurement voltage source.

2. The electronic LED circuit arrangement as claimed in claim 1 , wherein the evaluation circuit passes a corresponding control signal to the drive circuit.

3. The electronic LED circuit arrangement as claimed in claim 1 , wherein an interrupted coding conductor represents the logic state “0” and a non-interrupted coding conductor represents the logic state “1”.

4. The electronic LED circuit arrangement as claimed in claim 2 , wherein at least two coding conductors are individually connectable to a measurement voltage source of the drive circuit and the coding conductors are furthermore connectable to the evaluation circuit.

5. The electronic LED circuit arrangement as claimed in claim 1 , wherein an electrical supply line for the circuit elements is provided by at least one electrically continuous coding conductor.

6. The electronic LED circuit arrangement as claimed in claim 1 , wherein the lead and the circuit arrangement are arranged on a common carrier.

7. The electronic LED circuit arrangement as claimed in claim 1 , wherein the lead is arranged on a flexible part of a carrier.

8. The electronic LED circuit arrangement as claimed in claim 1 , wherein the coding conductors are interruptable by perforation, stamping and/or milling.

9. The electronic LED circuit arrangement as claimed in claim 1 , wherein the lead is electrically connectable to the drive circuit and/or to the circuit arrangement by plug connectors.

10. The electronic LED circuit arrangement as claimed in claim 1 , wherein the LED circuit arrangement has a plurality of LED chains each having a plurality of LED components, said LED chains being electrically connected in parallel with one another.

11. The electronic LED circuit arrangement as claimed in claim 10 , wherein the coding is correlated by the brightness grouping of the LED components used in the LED circuit arrangement.

12. A method for coding an electronic LED circuit arrangement, as claimed in claim 1 , wherein the lead is coded by perforation, stamping and/or milling after the completion of the electronic LED circuit arrangement, in accordance with the properties, parameters and/or functions of said electronic LED circuit arrangement.

13. The electronic LED circuit arrangement as claimed in claim 6 , wherein the common carrier comprises a printed circuit board.
