An LED lighting system improves efficiency of authentication by separating a controller to control the light of the LED and receive an external control signal from the LED lighting device. An lighting device(100) converts the inputted AC power to the DC power. The lighting device receives the voltage/current-control signal transmitted from the outside through communication and controls the voltage and the current level supplied to the LED illumination. A controller(200) recognizes an operation signal inputted through an input unit(300). The controller generates the voltage/current-control signal of the LED illumination and provides the generated voltage/current-control signal to the lighting device. |
