Abstract
Driving a lighting device by a driving circuit for providing driving power for driving a lighting device, and by a decoupling unit for electrically decoupling the driving circuit from a lighting circuit. The driving power is transferred at least partially from the driving circuit to the lighting circuit, and the lighting device is arranged within the lighting circuit such that its anode is at ground potential of the driving circuit.
