Patent ID: 8791638

Claim:
A light-emitting diode lighting system, comprising: 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 light-emitting diode lighting device assembly connected to the lighting device driver through two contacts, comprising: a plurality of light-emitting diode lighting devices having a plurality of lighting device connection bases and a plurality of light-emitting diode units, each lighting device connection base having a positive terminal and a negative terminal and is connected to a corresponding light-emitting diode unit for transmitting a lamp voltage and a lamp current to the corresponding light-emitting diode unit; wherein the lighting device connection bases are connected in series with each other to allow the light-emitting diode 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.
