Power supply for LED lamp with triac dimmer
ActiveUS20170027029A1Reducing bleeder current consumptionImprove power factorElectrical apparatusElectroluminescent light sourcesSilicon-controlled rectifierTRIAC
A bleeder circuit is provided in a switched mode power supply (SMPS) that provides a compensation current when the loop current drops below the holding current of the TRIAC to alleviate light flickering problem. Further, automatic power factor correction is also provided in embodiments of the invention, which enables the output current to be in phase with the input voltage. The power factor correction not only improves the efficiency of the power supply, it can also reduce the compensation current and the duration in which compensation current flows, thereby reducing the power loss in the bleeder circuit.
