摘要
针对HV LED设计了一套无线灯控系统。分析了HV LED灯的优势,驱动电路恒流的实现原理和PWM调光原理,以及说明了Zig Bee无线串口透传的设计方案。实验结果表明设计的驱动电源的具有良好的恒流特性和输出一致性,且可以通过无线控制实现在宽范围平滑连续的PWM调光。
A wireless lighting control system is designed for HV LED. This paper analyzes the advantages of the HV LED,the implementation principle of driving circuit for constant current and the principle of PWM dimming,and illustrates the design scheme of the Zig Bee wireless serial port. The experimental results show that the driving power supply designed has a good constant current characteristics and output consistency,and can be realized through wireless control in a wide range of smooth and continuous PWM dimming.
