摘要
随着现代社会的快速发展,科技的进步使电灯的样式、种类以及对灯的控制方式千变万化。资源的大量开采,能源在逐渐的减少,要建立起节约能源的意识,电能的节约首当其冲,而电灯的使用最为普遍。设计自动控制灯开关的电路是非常必要的,声控开关灯就是其中的一种。声光全控灯是在灯内加入声光延时线路,是集声学、光学和延时技术为一体组成的声光延时线路,广泛用于楼道、建筑走廊、洗漱室、厕所、厂房、庭院等场所,是现代极理想的新颖绿色照明开关,并延长灯泡使用寿命。
声光控灯延时开关的设计与制作,其主要工作方法是由声控和光控传感器来感应周围环境的变化,而做出相关的动作,从而控制照明灯的开关。白天当光线照射到光敏电阻上时,其通过感应使电路封锁声音通道,使声音脉冲不能通过,则灯泡不受声音控制,即声控传感器暂时失去作用,灯泡不亮。夜间或光线较暗时,光敏电阻因无光照呈低阻,经感应使声音通道开通,当有人走动或有人谈话时,通过声控传感器的感应,使得灯泡自动点亮,经过内部设定的时间后,灯泡自动熄灭。从而实现了“人来灯亮,人去灯熄”,杜绝了长明灯,免去了在黑暗中寻找开关的麻烦,尤其使上下楼道更方便。

Abstract
With the rapid development of modern society, the progress of science and technology make the lamp styles, species and light control mode the myriads of changes. Massive resource exploitation, energy is gradually reduced, to establish the awareness of energy conservation, energy saving and be the first to bear the brunt, the monly used. Design of automatic control switch circuit is very necessary, voice-activated switch light is one of a kind. Sound and light controlled lamp in lamp is added in the acousto optic delay line, is a collection of acoustic, optical and time delay integration technology position of acousto optic delay line, widely used in building, building corridors, washing room, toilet, factory buildings, gardens and other places, is the modern ideal of novel green lighting switch, and prolonging the service life of bulb.
Sound and light-controlled lamp delay switch design and production, the main method is by voice and light sensor to sense the changes of environment, and make the relevant action, so as to control lighting switch. The day when the light is irradiated to the photosensitive resistor, the circuit by induction to the blockade of sound channel, make sound pulse cannot pass through the bulb, is not controlled by the sound, the sound sensor is temporarily out of action, the light bulb does not light.
