1、 声光双控自动照明开关 2010 年 5 月 20 日 I I 摘摘 要要 在学校、机关、厂矿企业等单位的公共场所以及居民区的公共楼道，长明灯现象十 分普遍，这造成了能源的极大浪费。另外，由于频繁开关或者人为因素，墙壁开关的损 坏率很高，增大了维修量、浪费了资金。而我的课题是声光控制路灯的设计，设计了一 种安全节电、结构简单、安装方便、使用寿命长的声光双控白炽灯节能路灯。 在本设计中介绍了声光双控路灯控制器的组成、性能，适用范围及工作原理，给出 各电路原理图及元件参数选择，节电效果十分明显，同时也大大减少了维修量、节约了 资金，使用效果良好。白天光照好，不管过路者发出多大声音，都不会是灯泡发亮
2、。夜 晚光暗，电路的拾音器只要检测到有声响发出，就会自动亮为行人照明，过几分钟后又 自动熄灭，节能节电。 关键词 声光双控 自动照明 节能 开关 II II Abstract In todays world， long lights are widespread in schools， institutions， industrial enterprises and other units of public places and residential areas of public corridor. This caused great waste of energy. In additi
3、on， due to frequent switching or man-made factors， the failure rate of the high wall switch， increased maintenance and waste money. So my topic is the design of sound and light control of street lamp，designed a new circuit， safe saving， simple structure， easy installation， long life of sound and lig
4、ht dual-controlled incandescent lamp energy saving lamp. In this essay，I want to introduce a variety of sound and light control of street lamp controller， composition，performance，application and working principle of the circuit diagram and component parameters，energy-saving effect is very obvious，but also greatly reduced the maintenance amount，save money with favorable results. During the day light is good， no matter how sound passer issued，will not be bright light bulb. Night dimming， the c
