| 摘 要： | 本文分析了影响白炽灯泡使用寿命的主要因素,采用串联整流二极管的方法降压,使灯泡在脉动电压为50HZ的状态下工作,可延长灯泡寿命20余倍。针对电源接通瞬间灯丝易烧断的现象,采用电子延时电路可使灯泡寿命延长10倍。

| Abstract: | This paper analyses the main factors that influence the life of incandescent bulbs.rectifying diode to step down the voltage and making the bulbs in corridor work in 50HZ pulsant viltage,we can lengthen the life-span of the bulbs to more than twenty times.Aimed at the phenomenon that filament of an incandescent light can burn up easily as the switch turnes on,We have used an electronic delay circuit to extend the bulbs life ten times. |
