Design of LED light parameters controlled based on WiFi

Abstract

Aiming at dimming light set is controlled by remote intelligent and is easily operated, the integration adjustment system of color and brightness has been set up on the widespread Wi-Fi. The whole system is mainly composed of mobile client and system control terminal. The mobile client is interface of user. The system control terminal hardware mainly adopts modular structure including power supply module, Wi-Fi module and control module. The application software has three operation interfaces in order to find, operate and control equipment. LED power supply can be controlled through mobile intelligent terminal software to complete basic operations such as turning on/ off the lights, dimming, and security setting. Light indicator can be adjusted by using PWM, and the color temperature can be adjusted by the proportion of the tricolor LED color collocation. Wi-Fi module can try to connect by phone transmission Wi-Fi. The result of examination is that the basic parameters, such as network name and password, can modify on the Wi-Fi devices after the connection is successful. Then IOT Manage software can choose interface of MCU module to realize data input and output operations, to realize adjustment the LED brightness, to realize adjustment color temperature on the tricolor LED lamp.
