Title: OPERATING DEVICE WITH POWER FACTOR CORRECTION AND RIPPLE COMPENSATION BY CHANGE IN OPERATION
Abstract:
A method for operating light-emitting means, wherein the light-emitting means is operated by at least one driver circuit, a power factor correction circuit feeds the energy store, and an energy store feeds the driver circuit, characterized in that the voltage at the energy store is monitored, and the level of current output to the light-emitting means is depending on the detected ripple of the voltage at the energy store, wherein the operation of the light-emitting means by the driver circuit is increased when the detected ripple of the voltage at the energy store exceeds a predetermined limit value.
