摘要
随着半导体技术的不断发展,LED统布线困难,功能简单等问题。本文提出一种基于CC2530的多功能LED灯无线控制系统,利用三基色(R,G,B)混色原理,得到色品坐标与占空比之间的关系式,通过PWM信号控制R,G,B 3组LED灯的占空比,实现LED灯任意调光与调色功能,以满足人民各种不同的需要,达到节能环保、绿色照明。实验证明,该多功能LED装饰中。
The LED lighting system has been widely applied to smart home with the continuous development of semiconductor technology. Aiming at the problems of wiring difficulty and simple function of LED control system at present,A multifunction LED light wireless control system based on CC2530 was proposed in this paper.In order to meet the different needs of the human,achieve energy-saving and get environmental protection,green lighting. This system realized any dimming and color grading function of LED light through two steps. Fist, It must get the relationship between the chromaticity coordinates and the duty cycle. Second,The duty cycle of R,G,B three LED lamps were controlled by PWM. The experiment proved that this system can satisfy with the requirements of smart home lighting and can be widely applied to home decoration.
