    摘要： An AC light emitting device, a driving device thereof and a driving method are disclosed. The driving device includes a sub-driving part turned on corresponding to each of positive and negative voltage regions of an AC voltage source to provide current paths for operating at least two LEDs, and a free-charge part charging with a voltage to be supplied to one of the at least two LEDs which is not operated while the other LED is operated by the sub-driving part. The AC light emitting device, the driving device thereof and the driving method thereby can solve problems, such as a decrease in power factor, severe total harmonic distortion, excessive flickering, and the like, due to operating characteristics of the AC light emitting device by application of an AC voltage source thereto.
