摘要：
A method of driving LED chips of same power but different rated voltages and currents includes the following steps: set a predetermined power; provide a LED chip which has a rated power accordant to the predetermined power; measure the LED chip to obtain a working current thereof while the LED chip is operated; provides a driving current to the LED chip, and maintain the driving current the same as the working current.
