其实节能灯故障中多数情况是灯管坏了,电子镇流器往往是完好的,只要稍作改动,花费两三元钱的代价就可以改制成低压直流电源,其输出功率可达数瓦到十多瓦,作为充电器、随身听、MP3播放器、小收音机等的直流电源非常实惠。本文将详细介绍节能灯的电路和改制为低压直流电源的方法,供爱好者参考。

As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, as battery capacities inevitably increase,charge currents will also increase to maintain or improvetheir charge times. Traditional linear regulator-based batterychargers will not be able to meet the charge currentand effi ciency demands necessary to allow a product torun cool. What is needed is a switching-based chargerthat takes just about the same amount of space as a linearsolution—but without the heat.
