摘 要：随着科学技术的发展，节能照明的需求已经越来越迫切。在一些诸如宾馆、住宅楼等场所，声、光、触三控的照明装置已经开始广泛应用，以此来实现节能的作用。夜晚有声亮灯，白天不亮，人们自由开关灯，是声、光、触三控电路显示的主要功能，且灯亮后，能延时十秒左右的时间。79151
本文通过二极管、电容和CD4069等器件连接电路，控制灯泡的点亮与否。电路使用光敏电阻、驻极体电容话筒和触摸式开关来作为对光信号、声音信号和人体静电信号的接收器件。将声控电路、光控电路和触摸电路有机整合，并配合延时电路，设计了声、光、触三控的延时照明电路。电路设计完成后，运用Multisim进行软件仿真，验证了电路的设计能够实现晚上有声亮灯，白天不亮灯且自主控制开关灯的基本功能。声、光、触三控的延时照明电路结构简单、反映灵敏，且制作成本低，可广泛被应用。

Abstract：With the development of science and technology, demand of energy saving lighting has become increasingly urgent。 In some places such as hotels, residential buildings, sound, light, touch three lighting control device has begun to widely used, in order to realize the energy saving effect。 Audio lights in the night, not bright during the day, people freely open to turn off the lights, is the sound, light, touch three circuit shows that the main function of the control。
In this paper, through the diode, capacitor and CD4069 such as connection, circuit control lights light up or not。 Circuit using photosensitive resistance, electret condenser microphone, sound and touch metal for use as a light signal and the human body electrostatic signal receiving device。 To the organic integration of voice control circuit, electric circuit and touch, and cooperate with the delay circuit, design of the sound, light, touch three delay control lighting circuit。 Circuit design is completed, using the Multisim software simulation, verify the design of circuit can realize audio lights at night, not bright lights in the daytime and the basic function of autonomic control open to turn off the lights。 Sound, light, touch three delay control lighting circuit structure is simple, responsive, and low production cost, can be widely used。
Key words: sound and light touch three control, time delay , CD4069, energy saving
