D to LED burned. Obviously, such a program when the supply voltage is lower than the voltage drop across the load can not be used.
(2) DC step-up drive. Its basic principle is to use switching devices with electrical energy storage devices boost resistance to limiting the way to work. Step-up drive the transformation efficiency is relatively high. The more significant advantage is its failure will not damage the LED. Step-up drive can only be used in the load tube pressure drop is always highe
