12288; 现在有关这个问题有很多各种不同似是而非的说法，有人说：在. 的伏安特性上，电压定了，电流也就定了。所以采用恒压和恒流效果是一样的。有人说LED并联时就应该采用恒压电源供电，而LED串联时就应该采用恒流电源供电；有人说，因为LED是恒流器件，所以要用恒流源供电；有人说，采用市电供电时就应该采用恒压电源供电，采用蓄电池供电时，就应该采用恒流电源供电。至于为什么这样要求，似乎谁也说不明白。 12288; 那么，到底是应该采用恒压电源，还是恒流电源供电呢？ 12288; 要深入了解这个问题首先要知道LED的伏安特性。 65292;所以它本身就是一个二极管。它的伏安特性和一般的二极管伏安特性非常相似。只不过通常曲线很陡。例如一个20mA的草帽LED的伏安特性如图1所示。 12288; 温度系数通常是-2mV/度（-1.5—2.5mV/°C）,也就是随着温度的升高，其伏安特性左移，假如所加的电压为恒定，那么显然电流会增加。而LED本身的效率很低，温升很高...65292;情况也是一样，而且由于功率大，散热更不容易，温升问题更加严重。 12288; 串联电阻只有限流的作用，也...12288;z...
