基于单片机的智能护眼灯设计

Based on Single Chip Microcomputer Intelligent Design of the lamp that Shield an Eye

设计了一种以单片机STC89C51为控制核心,通过光敏电阻对外部的光线进行检测来调节灯光的亮度,以测距模块对物体或人的距离检测来控制LED灯的亮与灭,以LCD显示时间、定时功能和报警电路进行提醒。根据需求设置可以手动按键来控制灯的亮与灭。可以预防视力的下降,对学习的坐姿进行提醒。通过实际应用验证了智能护眼灯可以有效的自动控制LED灯的亮与灭、自动调节灯的亮度,自动检测距离等功能。本电路具有成本低、电路简单、性价比高等优点,在节约能源方面比普通节能灯存在着很大的优势。

We design a microcontroller STC89C51 as control core, through the photosensitive resistance to external light detection to adjust the brightness of the light, to distance measurement module for detecting the distance of the ob- ject or person to control the LED lights on and off, with LCD display to remind, timing function and alarm circuit. Ac- cording to the requirement setting, can control the light and extinguish of the lamp manually. You can prevent the loss of vision and remind you of your sitting posture. Through practical application, the smart eye lamp can effectively control the lighting and extinguishing of LED lights, automatically adjust the brightness of the lamp, and automatically detect the distance and other functions. This circuit has the advantages of low cost, simple circuit and high cost performance. It has a great advantage over ordinary energy-saving lamps in saving energy.
