摘要
导出多个LED混联后端电压与电流的关系,通过LED照明负载特性的分析,得出LED照明最好使用恒流驱动电源的结论,最后给出LED驱动电源的几种驱动方案。
The relationship between terminal voltage and currrent are derived when several LEDs are connected in series parallel. After analyzing the load characteristics of LED lighting, it is concluded that it would be best to use constant-current sources for LED lighting. Finally several schemes for LED driving electric sources are proposed.
