Abstract
The invention relates to an operating device (10) for at least one light-emitting diode (9) having an input (11) for coupling to a DC bus (6) in order to receive a DC supply voltage. The operating device (10) has a configurable emergency light function. The operating device (10) is designed to produce, in the emergency light case, the LED currently for the at least one light-emitting diode (9) in dependence on how the emergency light function is configured.
