摘 要
社会的进一步发展，各式各样的灯层出不穷，为了防止公物损坏，节约用电，设计了各种控制灯，例如公共场所和居民居住区的公共楼道普遍使用机械手动开关,由于各种原因往往出现许多灯泡点亮长明的现象,故使灯泡寿命短,浪费电量,为国家、单位、个人造成经济损失。
另外，由于频繁开关或其他人为因素，墙壁开关的损坏率很高，既增大了维修量、浪费了资金，又容易造成事故隐患。因此，设计研制一种电路新颖、安全节电、结构简单、安装方便的声控灯节能自动开关显得相当有必要。使公共场所和居民居住区的公共楼道灯在白天时不亮，晚上闻声自亮，待人走后，几十秒后自动关闭，既方便，又省电。

声控灯的原理与设计
ABSTRACT
For the further development of a wide variety of light after another, in order to prevent damage to public property, saving electricity, has designed various control lights, such as public places and those who are living in the public corridor widespread use of mechanical manual switch, for various reasons are often there were many light bulbs lit Changming phenomenon, it is to make lamp life is short, a waste of electricity for the country, units and individuals causing economic losses. In addition, due to frequent switching, or other man-made factors, the failure rate of a high wall switch, both increasing the amount of maintenance, waste of funds, but also easily lead to accidents. Therefore, the circuit design and development of a novel, safe energy-saving, simple structure, easy to install voice-activated energy-saving automatic switch corridor lights appeared to be quite necessary.To make public places and those who are living in the public corridor lights during the day without light at night from Wen Sheng-liang, treat people left, tens of seconds automatically shut down, which is convenient, but also energy saving. The following introduces the principle of voice-activated switch.
Keywords: Circuit board Voice-activated switch Control Power
