一种基于直流电源的声光控LED照明灯

A Sound-Light Controlled LED Lamp Based on DC Power

采用直流电源下基于振荡波关断的声光控开关电路,控制发光二极管(LED)照明灯的工作.其适用于没有220 V正弦交流电电网的特殊公共场所的照明,以及电路频繁启动或关断的状态.结果表明,该照明方法简单,节能效果好,还能提高使用者的舒适度.

Based on oscillation wave sound-light controlled switch,LED lamps circuits with DC power can be controlled on and off.It can be used for illuminations in special public places without 220 volt sine AC,or in circuits where frequently turning on and turning off are required.The results show that the method of illumination is quite simple,has a good energy saving effect and can improve convenience of users in daily life.
