在灯泡照明线路上串一整流二极管,可大大延长灯泡使用寿命,电路如图。 图中S即一般的拉线开关(原来就有的),只需将按照明灯炮的二线中的任一线剪断,串入一整流二极管后用胶布包好即可,二极管方向不限。 加上整流二极管后,灯泡二端电压约为原来的一半,耗电约为原来的1/4,故可将100W灯泡做25W使用,60W灯泡做15W使用……灯泡寿命可延长数十倍。特别适合于电压有时偏高,经常烧灯管处使用。
A series of rectifier diodes in the bulb lighting circuit, can greatly extend lamp life, the circuit shown in Figure. S is the general drawing switch (originally there), just follow the line in accordance with the light of the second line of any cut, string into a rectifier diode wrapped with adhesive tape, the diode direction is not limited. Coupled with the rectifier diode, the voltage at both ends of the lamp is about half of the original, the power consumption is about the original 1/4, it can be used to make 25W 100W bulbs, 60W bulbs do 15W ... ... lamp life can be extended several times. Particularly suitable for high voltage sometimes high, often used at the lamp.
