Abstract:
1. A light-emitting diode (LED)-airfield light at least comprising: a printed-circuit board with at least one controller; a first LED-module with at least one first LED; a second LED-module with at least one second LED; a first cable connecting the printed circuit board with the first LED-module and a second cable connecting the printed circuit board with the second LED-module; wherein the first and second LED-modules each comprises a memory for storing status information about the respective first and second LEDs; wherein the controller is configured to read the status information from the each memory and to drive the at least one first LED via the first cable and the at least one second LED via the second cable in accordance with the status information; wherein the first and second cables each has at least one connector for connecting the cable with at least one of the printed-circuit board and the corresponding one of the first and second LED-modules; wherein the first and second cables each comprises at least a first signaling line and a second signaling line for connecting the respective memory with the printed-circuit board, the first and second signaling lines being arranged symmetrically under a rotation of the connector; and wherein the controller is configured to establish communication with at least one of the memories, and when communication fails, resolving a signaling line mismatch by permuting the respective first and second singling lines and re-establishing a communication with the at least one of the memories.
