灯泡在被开启的瞬间，其灯丝要受到约５ｍｓ瞬间浪涌电流冲击，此冲击若天长日久反复作用于灯丝则加速灯丝的损坏。虽然卤素的采用可在一定程度上减弱灯丝损坏，但从灯泡的延寿角度而言尚不是根本之策。换句话说，灯泡的延寿问题迄今仍是有待人们攻克的难点。不久前由英国... The moment the bulb is turned on, its filament is subjected to an instantaneous inrush current surge of about 5ms, which, if repeatedly applied over a long period of time, accelerates the filament’s damage. Although the use of halogen can be reduced to a certain extent, the filament damage, but from the lamp life extension point of view is not the fundamental solution. In other words, the longevity of light bulbs so far remains to be overcome by people difficult. Not long ago by the British ...
