    • 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.
    • 公开了一种AC发光器件,其驱动装置和驱动方法。 驱动装置包括对应于AC电压源的正电压区域和负电压区域中的每一个导通的辅助驱动部件,以提供用于操作至少两个LED的电流路径,以及向要供应到的电压充电的自由充电部分 所述至少两个LED中的一个在另一个LED由副驱动部分操作时不被操作。 由于AC发光器件的驱动装置和驱动方法可以解决由于AC发光器件的操作特性而导致的功率因数降低,严重的总谐波失真,过度闪烁等的问题 向其施加AC电压源。
