本文设计了一套以HT66F70A 为主控芯片的智能灯光控制系统，实现自动模式、手动模式转换。该系统通过 亮度感应模块采集外界光、热释红外人体传感模块采集人员检测信号，结合遥控器控制方式，通过单片机程序控制继电器对照 明灯进行有效操控。它不仅能有效判断人员是否存在，还能人性化选择室内照明方式，具有比较重要的实际应用价值。

In this paper, a set of intelligent lighting control system based on HT66F70A is designed to realize the shift between automatic mode and manual mode. The system controls light effectively through brightness sensor module which collects external light signal and pyroelectric infrared sensor module which collects personal infrared signal, combined with the remote control which can control indoor lighting with single-chip microcomputer program controlling the relay. It not only can effectively judge whether human exists, but also can choose the way of indoor lighting, having important practical value.
