    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).

    Abstract translation: 本发明涉及一种用于操作LED（13）的方法，包括具有至少一个LED（13）的驱动器模块（10）和LED模块（11），该LED模块（11）由驱动器模块（10） ），其中驱动器模块（10）具有第一连接（1），其被设计为将LED模块（11）馈送到电流，并且具有作为接地连接（GND）的第二连接（2），其中 所述LED模块（11）经由第一连接（1）由所述驱动器模块（10）馈送电流，并且存在作为接地连接（GND）的第二连接（2），其特征在于，所述驱动器模块（10） 临时降低第一连接（1）处的电压并监视第一连接（1）处的电压，并且被设计为评估所述连接处的电压的变化，作为来自LED模块（11）的信息的传送。
