基于单片机和模糊控制的LED智能调光系统设计

摘要

设计了一个 LED照明灯的智能调光系统，采用 AT89 C2051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, Using AT89C2051 single- chip computer as the main controller, real- time measurement of ambient light illumination using a light intensity sensor, 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 to the preset ambient light illumination, so as to meet the application needs. Both energy saving and environmental protection and intelligent convenient, practical strong.
