Abstract

An electronic control gear for operating at least one of at least one LED and at least one discharge lamp is provided. It may include a first terminal for coupling to a phase of an AC voltage supply; a second terminal for coupling to the neutral conductor of the AC voltage supply; a control input for coupling in a control signal of a control apparatus; a first output for coupling to the LED; a second output for coupling to the discharge lamp; a first driver circuit for the LED; a second driver circuit for the discharge lamp; an evaluation apparatus for evaluating the control signal at the control input, the evaluation apparatus comprising a microcontroller, which activates said driver circuits depending on the control signal, wherein a first capacitance is coupled between the second terminal and the control input.
