The Design Of Intelligent Control System For LED Healthy Lighting

More and more people are myopic in our country at present.The businessmen seize the opportunity and produce a lot of so-called eye-protection lamps,but the lamps don't really protect eyes.Ophthalmologists commit to researching a true eye-protection lamp,but don't have suitable tools.This paper mainly studies an intelligent control system suitable for LED healthy lighting to help medical researchers in the field to carry out comprehensive and convenient scientific research,hoping to lay the foundation for the research on the really eye-protection lamp.First,this paper describes some aspects that affect the health of lighting,such as strobe glare,uniform illumination,etc.Then the paper simulates light conditions of the experimental area by Matlab,TracePro and other tools.With two LED tubes as the optimization object,when two different LED particles are used,the uniformity of the light receiving surface is 0.87,which is improved by 64.2% compared with the prior optimization.It makes the results more reliable.Third,the hardware design of the LED intelligent control system is carried out,which includes the MCU central controller,LED constant current drive,power supply module and Zigbee communication module.MCU central controller is the core of the whole system;LED constant current drive provides stable current;Power supply module is the basis of the whole system,which provides a stable and reliable power supply system;Zigbee communication module can form a network and connects the user and the terminal controller.Fourth,the paper uses C language to design the software part of the system.The system adjusts the brightness of LED by PWM method.Finally,it introduces the function of the Web terminal of the LED intelligent control system in detail.It mainly includes the main interface,node setting,area setting,mode setting and communication setting.It provides users with a good operating interface and achieves remote control.
