摘要
本文首先对交流LED的封装及特性进行详细的分析,然后结合其特点,提出了一种利用恒流二极管驱动交流LED负载的新型照明方案。该方案完全摒弃了传统的开关电源,克服了开关电源电磁干扰严重等缺点,实验结果表明该照明方案具有很高的功率因素和电源效率。
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.
