Abstract
The invention relates to a device for operating LEDs, comprising a driver module and an LED module (11), which is controlled by the driver module (10) and has at least one LED. The LED module (11) is fed a current by the driver module (10) via a first connection (1), and a second connection (2) is present, preferably as a ground connection (GND). The device is characterised in that the LED module (11) is connected to the driver module (10) by means of a third connection (3), which is designed as a data channel, a voltage fed by the driver module (10) being applied to the data channel.
