Abstract
A light emitting diode (LED) lighting system may include a plurality of LED modules and a server. The plurality of LED modules can include LED lighting devices and provide a human detection signal and distance information regarding a distance from a human, in the case of human detection, respectively. The server may control the LED lighting devices upon receiving the human detection signal and the distance information from the plurality of LED modules. The server may compare the distance information with a pre-set reference distance and controls brightness of the LED lighting devices according to the comparison results.
