Abstract:
A system and method for driving a LED is disclosed. The system is switched in turn between a constant-current mode circuit and a constant-voltage mode circuit. Accordingly, the forward voltage of the LED could be maintained constant, and the efficiency in power consumption could be substantially increased.
