Abstract:
A lighting system includes: at least one lamp each including an LED unit; and a power converting device disposed outside of each lamp, and including a first EMI filter, a power converter and a second EMI filter. The first EMI filter is for receiving an AC input voltage from an AC power source, and filters the AC input voltage to generate a filtered voltage. The power converter is for receiving the filtered voltage from the first EMI filter, and performs AC to DC conversion on the filtered voltage to generate a converted voltage. The second EMI filter is for receiving the converted voltage from the power converter, and filters the converted voltage to generate a DC output voltage for receipt by the LED unit of each lamp.

Claim (Index 2):
The lighting system of  claim 1 , wherein said power converter includes:\n a rectifying and filtering circuit coupled to said first EMI filter for receiving the filtered voltage therefrom, and rectifying and filtering the filtered voltage to generate a rectified voltage; a flyback converting circuit coupled to said rectifying and filtering circuit for receiving the rectified voltage therefrom, coupled further to said second EMI filter, and further receiving a pulse width modulation (PWM) signal, said flyback converting circuit performing DC to DC conversion on the rectified voltage based on the PWM signal to generate the converted voltage for receipt by said second EMI filter; a feedback circuit coupled to said flyback converting circuit for receiving the converted voltage therefrom, and generating, based on the converted voltage and a scaling factor, a feedback signal related to a product of a magnitude of the converted voltage and the scaling factor; and a PWM control circuit coupled to said feedback circuit for receiving the feedback signal therefrom, coupled further to said flyback converting circuit, and generating the PWM signal based on the feedback signal for receipt by said flyback converting circuit.
