Operating device for a lighting means and method for operating an operating device
2012
An operating device (2) for a lighting means (3) comprises a power factor correction circuit (20), a transducer (30) connected to the power factor correction circuit (20) and having an output (41) for the energy supply of the luminous means (3), and a control means (14) having an input (51) for detecting one of the power factor correction circuit (20) to the transducer (30) provided voltage (Vbus). The control device (14) is adapted to perform an evaluation of voltage ripples of the voltage (Vbus) and (to associated based on the evaluation, a to the output (41) of the transducer (30) load (3) and / or an output power of the converter to determine 30).
