PURPOSE: A system and a method for maintaining an assembly of a light emitting diode are provided to receive respective LED light emitting states of LED assemblies through a detecting unit which moves on a road to display the light emitting state on facility manager, thereby easily maintaining the LED assemblies. CONSTITUTION: A plurality of LED(Light Emitting Diode) assemblies(100) includes a casing, an LED, and a controller of an RFID(Radio-Frequency IDentification) tag type. The LED emits light inside the casing. The controller checks a state of the LED inside the casing. A detection unit(200a) of an RFID reader type transmits a state of the LED. The detection unit reads an RFID tag. A central control device(300) displays the LED state to a facility manager. |
