Abstract
An LED lighting device driven by a rectified AC voltage includes a luminescent device, a charge storage unit and a current controller. The charge storage unit is configured to turn on the luminescent device when the rectified AC voltage is still insufficient to turn on the luminescent device. The current control unit is configured to allow the LED lighting device to have constant luminance regardless of the level of the rectified AC voltage or dimmer condition, thereby improving flicker phenomenon.
