Abstract

LED lighting, as a new type of lighting, has already been widely used. High reliability LED depends on drive control circuit to obtain steady electric current to make LED lighting more stable and uniform. In this paper, anti-surge and EMC were designed on the basis of LED high reliability power supply. In order to simplify the circuit and achieve good power factor and efficiency, a 15W flyback power was also designed by using chip LNK406EG. Experiments verified that the power supply made in this paper can get good power factor, small loss, steady output and high efficiency.
