Abstract
An LED lighting device includes first through third luminescent devices and first through third current controllers. The first and second luminescent devices are driven by a rectified AC voltage for providing light of a first color. The third luminescent device is driven by the rectified AC voltage for providing light of a second color different from the first color. The first through third current controllers are configured to regulate the current flowing through the first through third current controllers according to a first current setting, a second current setting and a third current setting, respectively. The color rendering index of the LED lighting device can thus be adjusted flexibly.
