An LED lighting device includes a first luminescent device, a second luminescent device, a first current controller, and a second current controller. The first current controller is coupled in parallel to the first luminescent device and configured to operate according to a first current setting, a switch-on voltage, and a switch-off voltage. The second current controller is coupled in series to the second luminescent device and configured to operate according to a second current setting. The first current setting, the second current setting, the switch-on voltage, and the switch-off voltage are adjusted by setting mode selection pins of the first and second current controllers. |
