Abstract
Provided is a LED lighting system, including a lighting device driver having a power converter for converting an input voltage into a first DC voltage and outputting a first current having a substantially constant current value; and a LED lighting device assembly connected to the lighting device driver through two contacts. The LED lighting device assembly includes a plurality of light-emitting diode lighting devices having a plurality of lighting device connection bases and a plurality of LED units. The lighting device connection bases are connected in series with each other to allow the LED lighting devices to be connected in series with each other, and the lamp voltage is applied across the positive terminal and the negative terminal of the lighting device connection base and is generated by dividing the first DC voltage, thereby allowing the lamp currents outputted by the lighting device connection bases are substantially equal.
