摘　　要：本次设计是以单片机控制为核心,采用光敏电阻进行环境亮度的检测,采用红外传感器感应在检测范围内是否有人。单片机通过接收到的红外检测模块和光线检测模块两路信号控制相应继电器,从而控制小灯的开关和亮度,实现书房灯的智能化。本设计包括硬件电路和软件编程。硬件包括单片机STC89C52、按键模块、红外检测模块、光线检测模块、LED照明模块等5个部分。整个电路设计比较简单清晰,调试也比较容易,其实用性比较强。Based on the single chip microcomputer the system adopts the photosensitive resistance to detect the ambient brightness, and the infrared sensor to detectwhether anyone is in the range of detection. Microcontroller can control the corresponding relay thus to control the switch and brightness of small lamp according two signals from infrared detection module and light detection module, so as to realize the intellectualization of the study lamp. The development work includes hardware circuit design and software programming. The hardware consists of five parts： single chip microcomputer STC89C52, key module, infrared detection module, light detection module and LED lighting module. The whole circuit design is relatively simple and clear, and the debugging is relatively easy, but its practicability is relatively strong.
