Abstract
In this paper, we perform an AC direct input using PA2200Q driver IC module to improve efficiency of LED. In consideration of durability of LED module and its light module and low cost, This LED light module without using any external capacitors and inductors can be adjust a current waveform automatically in order to accomplish a low noise and high power factor including temperature adaptability. There are also the advantages of not only providing wide range of input voltage (200-260VAC) with 50/60Hz but also improves EMI and power factor as well as decreasing harmonics with sequentially current tracking method.
