教室里的日光灯经常因两端或一端变黑就得更换。网上查询我们了解到,日光灯的两端是两段灯丝,一端不能正常使用,另一端其实并没有坏。这样,直接报废,是不是浪费呢?可否用一个等效的电阻来取代烧坏或老化的那一端灯丝呢?根据日光灯的工作原理,在灯管与镇流器之间增加一个转接器,在转接器内用一个与灯丝电阻相等的等效电阻 The fluorescent lamps in the classroom often have to be replaced due to the darkening of the ends or ends. Online inquiry we learned that the two ends of the fluorescent lamp is two, one end can not be used normally, the other end is not bad. In this way, the direct retirement, is not waste it? Can use an equivalent resistor to replace the burn or aging of the filament it? According to the working principle of fluorescent lamp, lamp and ballast to add an adapter, Use an equivalent resistance in the adapter equal to the filament resistance
