摘要
LED灯有节能、高效等诸多优点,在节能环保领域具有广阔的发展前景。针对当前展会灯光能耗偏高、LED成像灯的眩光和偏色等问题,提出基于MSP430单片机的LED智能控制系统,通过传感器实现动静探测和光敏检测,将反馈信号传送给单片机,改变单片机输出的脉冲信号占空比,从而实现脉冲宽度调制(PWM)功能。选用LED恒流驱动器带动负载,并通过LED成像灯的二次光学设计和RGBW/Y五色混色,实现LED展会灯的智能化和集约化应用,达到节能高效、舒适的目的。
LED lamp has many advantages such as energy efficiency, it has a broad development prospect in the field of energy saving and environmental protection. To solve the problems of the current high energy consumption of exhibition lighting LED, its glare and color deviation,the paper proposes LED intelligent control system based on single chip micro-computer MSP430.The system can do movement detection and sensitive detection through the sensor,deliver the feedback signal to the microcontroller,change the duty ratio of the output pulse signal to realize the control function of PWM.By selecting constant current LED drive,and two optical design and RGBW/Y color mixed color.The system realizes the intelligent and intensive application of LED expo lamp, and achieves the purpose of energy efficiency and comfort.
