Abstract:
A method of driving LED chips, wherein the LED chips have different specifications, includes 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; and D. providing power with the selected setting current to the LED chip. Whereby, the method could be applied to drive LED chips of several different specifications.
