Description

声光双控延时节能电灯
技术领域
本实用新型涉及电光源照明技术领域,具体是一种声光双控延时节能电灯。 
背景技术
楼道、走廊照明和控制开关有多种方式可选,白炽灯光效低,功耗大,但目前较小功率灯泡用量不是较多,做到及时关灯是可以起到节省电能的作用。控制开关手动时有不便,特别是老人和小孩使用不便。 
发明内容
本实用新型的目的是提供行人脚步声开灯照明的一种声光双控延时节能电灯。 
本实用新型技术解决方案为:包括灯头、灯泡,还包括声控传感陶瓷片、光敏二极管、六非门集成电路、三极管放大器、继电器及声光双控直流电源组成,其中,声控传感陶瓷片接入由第一个非门的输入输出之间跨接偏置电阻R1构成线性放大器,输出信号经第二个非门反相,通过电容C1耦合接入第三个非门至第四个非门,在第三个非门输入端并接光敏二极管和偏置电阻R2,第四个非门输出经电容C2接入由第五个非门和第六个非门及电阻R4、电容C3构成的单稳态触发器,由第六个非门输出端经电阻R5接入三极管放大器,驱动继电器,灯泡插入灯头经继电器触点JK接入交流电源; 
其中,声光双控直流电源由电容C4电阻R6接入交流电源,经二极管VD3整流、二极管VD4稳压和电容C5滤波。 
本实用新型产生积极效果是:行人走动产生声响开灯的声光双控延时电灯照明,使用方便,起到节省电能作用。 
附图说明
图1本实用新型技术方案原理框图 
图2声光双控延时节能电灯电路 
具体实施方式
参照图1、2,本实用新型具体实施方法和实施例:包括灯泡8、灯头6,还包括声控传感陶瓷片1、光敏二极管2、六非门集成电路3、三极管放大器4、 继电器5及声光双控直流电源7组成,其中,声控传感陶瓷片1接入由第一个非门a的输入输出之间跨接电阻R1构成线性放大器,输出信号经第二个非门b反相,通过电容C1耦合接入第三个非门c至第四个非门d,在第三个非门c输入端并接光敏二极管2和偏置电阻R2,第四个非门d输出经电容C2接入由第五个非门e和第六个非门f及电阻R4、电容C3构成的单稳态触发器,由第六个非门f输出端经电阻R5接入三极管放大器4,驱动继电器5,灯泡8插入灯头6经继电器触点JK接入交流电源。 
直流电源7由电容C4、电阻R6接入交流电源AC220V,经二极管VD3整流、二极管VD4稳压和电容C5滤波。 
图2,在白天,光敏二极管VD1光照作用呈低阻状态,非门c的输入端低电平不受声控。此时,电阻R3引入直流电源正极,使单稳态触发器输入端没有触发信号时处于高电平,输出为低电平,三极管放大器截止,继电器触点JK处于常开,没有通电灯泡D不亮。 
夜间,光敏二极管VD1无光照呈高阻状态,非门c受非门b的控制,这时,楼道、走廊有行人走动声或讲话声响,声控传感陶瓷片ST接收到微弱的声信号,经非门a构成的线性放大器放大、非门b反相整形为矩形脉冲信号,由电容C1耦合至非门c,经非门d输出为低电平,触发单稳态触发器至三极管VT电流放大驱动继电器J,其触点JK吸合,灯泡D通电点亮,经过单稳态触发器电容C3对电阻R4放电的延时,触点JK释放,灯泡D断电熄灭。
