摘要:
LED是一种具有高效节能、绿色环保、使用寿命长等优点的新型光源.本文所述的LED灯模拟自然光强系统,以AT89C51单片机为核心控制芯片,实现在阴雨天的昏暗早晨,利用LED灯补光以模拟最佳自然光强渐亮的效果,将有助于改善人们起床后的精神状态.系统采用PT4115大功率LED恒流驱动方案,可实现对LED灯的多级PWM调光控制.本文给出了系统的硬件与软件设计,并以自然光强变化的拟合曲线作为标准,对LED光亮进行控制.
Abstract:
LED is a new type of light source with high-energy,green-environmental protection,long-life and other advantages.In this paper,the LED lighting system for simulating natural light intensity uses AT89C51 MCU as the core control chip,with LED light compensation,to achieve the best gradually bright effect of simulating natural light intensity in the rainy dark morning,which will improve the mind states when people wake up.The system adopts PT4115 high-power LED constant current driving scheme,which can realize multistage PWM dimming control of LED lights.The paper gives the hardware and software design of the system and uses the fitting curve of natural light intensity as the standard curve of LED brightness control.
