Abstract
The invention relates to a method for transmitting information from an operating device (K) for lamps (L), in particular a converter for LEDs, to a control unit (ST) connected to the operating device (K) via voltage supply lines (8, 9) thereof, having the following steps: the control unit (ST) preferably periodically temporarily interrupts an AC supply voltage (Vin) of the operating device (K), and the operating device (K) applies a voltage signal (V2) to the voltage supply lines (8, 9) during the interruption of the AC supply voltage (Vin) which is evaluated by the control units (ST) as information.
