The control circuit unit 60 is electrically connected to the switching element unit 30, and is electrically connected to the infrared sensor monitoring unit 50. When the control circuit unit 60 receives an electric signal transmitted from the infrared sensor unit 40, the control circuit unit 60 turns on the switching element unit 30 to electrically connect the light emitting diode unit 10 to the converter unit 20. . Therefore, when the object is moving, the light emitting diode unit 10 is turned on by receiving power from the converter unit 20.

In addition, the control circuit unit 60 turns off the switching device unit 30 when the electric signal is not transmitted from the infrared sensor unit 40 to electrically disconnect the light emitting diode unit 10 and the converter unit 20. . Thus, when there is no movement of the object, the light emitting diode unit 10 is turned off by turning off power from the converter unit 20.
