When the power supply unit 2 is turned on, an infrared ray is blinked at a predetermined cycle. When the presence of a person is confirmed in front of the display by the object confirmation unit 1, if the presence of the display is small, the current value is increased to increase the illuminance when the illuminance of the display is small, and when the illuminance is large, Try to leave it as it is. If it can be confirmed that no human is present, the current value is lowered to lower the illuminance when the illuminance of the display is high, and the illuminance is kept low when the illuminance is low.
