  The control unit 12 includes a PWM switch unit 12A and a control circuit 12B.

  The PWM switch unit 12A controls the power supply to the LEDs 2a to 2c and the cutoff thereof, thereby controlling the light quantity of the LEDs 2a to 2c.

  When supply and interruption of current to the LED are repeated, the LED is repeatedly turned on and off. If the time interval between turning on and off the LED is short, humans feel that the LED is always on.

  In this case, the light quantity of the LED light emission part 2 changes according to a duty ratio. The duty ratio is a ratio between the pulse width and the switching period.

  In step S205, the control circuit 12B generates a PWM signal corresponding to the light emission mode included in the confirmed control information, outputs the PWM signal, and controls the light emission color and the light amount of the LED light emitting unit 2.

  Further, the control circuit 12B detects whether or not the power consumption detection circuit 8 detects that the power consumption value is less than the stop voltage. Specifically, the control circuit 12B checks whether or not a consumption signal has been received from the power consumption detection circuit 8.

  When the power consumption detection circuit 8 detects that the power consumption value is greater than or equal to the stop voltage value, the control circuit 12B executes step S206, and the power consumption detection circuit 8 detects that the power consumption value is less than the stop voltage value. Then, step S208 is executed.

  In step S206, the control circuit 12B confirms whether or not the receiving unit 10 has received a control signal. Specifically, the control circuit 12B confirms whether or not a control signal has been received from the receiving unit 10.
