摘要：A power supply unit provides a voltage, and a driving current to a series of lightemitting diodes. A dimming unit adjusts a duty cycle of an original dimming signal to
generate a dimming signal according to the driving current and an ideal current. A currentsink coupled to the series of light emitting diodes adjusts a duty cycle of the drivingcurrent according to the dimming signal.
