    • PURPOSE: An intelligent type multipurpose display wireless control management system and a method thereof are provided to include a portable LED module central control apparatus, thereby control the LED lighting nodule remotely. CONSTITUTION: A main electric supplier(310) applies the predetermined power source to a LED lighting apparatus. A constant voltage circuit corrects the voltage in which the main electric supplier applies to the LED lighting apparatus through a PWM(Pulse Width Modulation) waveform, and controls the voltage applied to the LED lighting apparatus to be maintained constantly. An illuminance sensor(330) generates the illumination status data and controls to maintain the predetermined brightness. A stable-current circuit(340) extracts the blink status data and the blink pattern data of the LED lighting apparatus connected through a current sensing. A control unit(350) transmits the illumination status data, blink status data, and blink pattern data to a wireless communication apparatus by the wireless communication, and controls the LED lighting apparatus in order to correspond with each of the blink status control data, illumination status control data, and blink pattern control data extracted from the control data which is received from the wireless communication apparatus.
