Driving apparatus of light emitting diode and driving method thereof |
摘要 |
A driving method of a light-emitting diode (LED) adapted to a driving apparatus is provided. The driving method includes detecting whether the driving apparatus performs dimming, and if the driving apparatus performs dimming, determining whether a predetermined requirement for dimming control is met or not. When the predetermined requirement for dimming control is not met, respective current magnitudes of a plurality of driving currents are regulated, and each of the driving currents is output for a full time of a period. Conversely, when the predetermined requirement for dimming control is met, each of the driving currents is output for a partial time of a period. |
