Abstract:
A control circuit for LED lamps comprises a rectifier module, a filter module, at least one additional expansion module, and an output control module. The filter module comprises a filter capacitor C 6.  The output control module is configured to output a PWM signal or a PFM signal. Each of the additional expansion modules comprises an additional filter circuit, a switch control circuit, and a duty cycle/frequency sampling circuit. The control circuit for LED lamps provided by the present invention utilizes the duty cycle/frequency sampling circuit to monitor the duty cycle or power of the PWM signal or the PFM signal output by the output control module in real time so as to output the control signal, and the switch control circuit controls the on-off of the switch of the additional expansion circuit according to the output control signal of the duty cycle/frequency sampling circuit, so that the capacitor of the additional expansion circuit can be connected in parallel or unparallel to the filter module, in full load conditions LED power PF value and THD value can conform to the corresponding standards.

Claim (Index 2):
The control circuit for LED lamps as claimed in  claim 1 , wherein the additional filter module further comprises a resistor connected in parallel with the additional filter capacitor.
