主权项 1. A method of driving LED chips, wherein the LED chips have different specifications, comprising the steps of: (a) defining a plurality of setting currents; (b) connecting a LED chip; (c) selecting one of the setting currents which matches a rated current of the LED chip; (d) providing power with the selected setting current to the LED chip; wherein each setting current relates to a reference voltage; the step of selecting one of the setting currents includes providing the LED chip with a testing current, which is a constant current, measuring a voltage of the LED chip while the LED chip is operating with the testing current, and selecting one of the setting currents according to the reference voltage which matches the measured voltage.
