A three-dimensional stage representation method and system are disclosed, for moving a plurality of illumination devices up and down independently. The method comprises the steps of: identifying a device to be operated from input containing information on length of a reel wire from an elevator device to an illumination device and brightness of an LED and generating an indication signal to the device to be operated; transmitting the generated indication signal to the elevator device if the device to be operated is the elevator device; operating the reel; transmitting the generated indication signal to the illumination device if the device to be operated is the illumination device; operating the LED; forming a three-dimensional object using all of the LEDs by operating each of the devices; and forming a dynamic three-dimensional object using all of the LEDs by repeating all of the above-mentioned steps.
