摘要
光控灯和声光控灯是居家照明的重要组成部分(如楼道、卫生间、小巷等),它们的出现使我们的生活方便许多,既可避免摸黑找开关造成的摔伤碰伤,又可杜绝楼道灯有人开、没人关浪费能源的现象。
介绍了用三极管和与非门芯片实现光控灯和声控灯的原理,重点介绍了二者的实现方法和具体细节,及制作过程中遇到的问题和相应的解决方案。

Abstract
Optically controlled lamp and acoustic control lamp play an important role in our daily life(like in corridor,toilet,alleyway and so on).They make our life more use of them,we can not only protect ourselves from the hurt that maybe caused in looking for the switches of lights in the dark,but also eliminate the phenomenon that someone turn on the light but nobody turn off to avoid the waste of resources.
It introduces the principle of how to use dynatrons and a nand gate chip to achieve the purpose that control the lights by light and sound,and specially stresses the ways and concrete details about how to use them to achieve the purpose and the solutions of the problems that will be met in the process of making it.
Key words: Optically controlled, acoustic control, mircphone, light dependent resistor
breakover, cutoff
