LED发光二极管，是一种能够将电能转化为可见光的固态的半导体器件，它可以直接把电转化为光。半导体晶片由两部分组成，一部分是P型半导体，在它里面空穴占主导地位，另一端是N型半导体，在这边主要是电子。当电流通过导线作用于这个晶片的时候，电子就会被推向P区，然后就会以光子的形式发出能量，这就是LED灯发光的原理。市面上家用灯具目前主流的就是这种LED灯。某用户在研制led灯具时，需要用到一颗LED驱动，我们推荐了必易微 LED驱动芯片 KP1063CSPA。

必易微LED驱动芯片KP1063CSPA应用电路如下所示：

KP1063CSPA应用在LED驱动板有如下优势：

1、有源功率因数校正技术，全电压功率因数＞0.9，提高了芯片的用电效率；

2、集成了高压500Vmos和高压启动电路，简化了系统设计，降低成本；

3、集成内部保护功能，输出过压保护、过热保护、短路保护等；

4、超低工作电流，恒流精度±1%；

5、集成有高压启动电路和变压器退磁检测电路，支持无辅助绕组设计。

综上所述：国产LED驱动芯片KP1063CSPA可以应用于LED驱动板，集成了内部保护功能，具备有源功率调节功能，提升效率。

【选型】国产LED驱动芯片SGM3752可P2P替换SY7200A应用于温控器，最大输出电压达35V

温控器目前非常广泛的用在办公室，商场以及小家庭里面，可以很方便的控制中央空调。温控器是通过LCD面板来显示温度等相关信息的，LCD本身不会发光，要想让其显示所要的数据，需要使用白光背光源，白色背光源一般由数个发光白色LED灯组成，LED灯的个数由屏的尺寸大小决定，要使LED灯亮，还要使用LED驱动芯片。
