Abstract (en)

[origin: WO2011026926A2] The invention relates to a method for the controlled AC operation of a preferably dimmable operating device for lighting devices, such as LEDs, OLEDs or gas discharge lamps. The interval from significant points of the flow of the current through the lighting devices and of the voltage at the level of the lighting devices is used for a cos (F) correction of an actual value and/or of a rated value of the control while taking into consideration the DC portion of the voltage at the level of the lighting devices and/or of the DC portion of the current through the lighting devices.
