Driving apparatus of light emitting diode and driving method thereof

A driving method of a light-emitting diode (LED), adapted to a driving apparatus, the driving method comprising:

• receiving a dimming signal;
• detecting whether the driving apparatus performs dimming;
• if the driving apparatus is detected to perform dimming, regulating at least one of a respective current magnitude and a respective outputting time of each of a plurality of driving currents in a period according to a duty cycle of the dimming signal, such that a sum of the driving currents calculated for a period is substantially proportional to the duty cycle of the dimming signal.

A driving circuit for driving a plurality of light-emitting diodes (LEDs), the driving circuit comprising:

• a plurality of switches, used to be coupled to the LEDs;
• a dimming detector, for receiving a dimming signal and outputting a dimming mode signal according to the dimming signal;
• a current control unit, for outputting a plurality of control signals according to the dimming mode signal and the dimming signal, wherein the control signals respectively control conducting states of the switches.
