LOW FLICKER ALTERNATING CURRENT (AC) LED DRIVER

摘要

In some embodiments, an apparatus comprising a rectifier that is configured to rectify an Alternating Current (AC) from an AC line to produce a rectified line voltage, at least one resistor operatively coupled to the rectifier, and at least one capacitor operatively coupled to the at least one resistor and ground is disclosed. In some instances, the at least one resistor and the at least one capacitor form a low-pass filter configured to reduce a ripple voltage of the rectified line voltage of the rectifier. In some instances, the at least one resistor and the at least one capacitor are configured to provide a minimum voltage on the at least one capacitor that is high enough to maintain at least one LED conducting current at a minimum level and maintain the at least one LED operational for substantially all of a line cycle of the AC line when the at least one LED is operatively coupled to the at least one capacitor.
