Abstract

The invention relates to a method for operating LEDs (13), comprising a driver module (10) and an LED module (11) having at least one LED (13), which LED module (11) is controlled by the driver module (10), wherein the driver module (10) has a first connection (1), which is designed to feed the LED module (11) with a current, and has a second connection (2) is present as earth connection (GND), wherein the LED module (11) is fed with a current by the driver module (10) via a first connection (1) and a second connection (2) is present as earth connection (GND), characterized in that the driver module (10) temporarily lowers the voltage at the first connection (1) and monitors the voltage at the first connection (1) and is designed to evaluate a change in the voltage at said connection as a transfer of information from the LED module (11).
