| Abstract: | This paper firstly makes a detailed analysis on the encapsulation and features of the AC LED, then considering its features, it puts forward a new lighting program, which uses constant current diode to drive the load of AC LED. The program completely avoids the traditional switching power supply, and overcomes the serious electromagnetic interference of switching power supply and some other shortcomings. The experiment results have shown that the lighting program has high power factor and power efficiency. |
