基于单片机和模糊控制的LED智能调光系统设计

Design of Intelligent Light-adjusted System for LED on Single-chip Computer and Fuzzy Control

设计了一个LED照明灯的智能调光系统,采用AT89C2051单片机为主控制器,使用光照强度传感器实时测量环境光照强度,经模糊计算,通过改变PWM信号占空比来控制调节LED灯的发光强度,使实际照度达到预设环境光照度,从而满足应用需求,既节能环保又智能便捷,实用性较强.

An intelligent light--adjusted system with LED lighting is designed. AT89C2051 single--chip computer is used as the main controller, and a light intensity sensor is used to measure the ambient light illumination. By fuzzy calculation, the duty cycle of the PWM signal is changed to control the luminous intensity of the LED lamp so that the actual illumination can reach the preset ambient light illumination and meet the application needs. The design has the advantage of energy saving, environmental protection and intelligent convenience. In a word, its practicability is strong,
