Further, reducing the output power of the LED unit 21 depends on the actual environment. For example, the output power of the LED unit 21 required at different times or at different venues is not The same, but the above-mentioned reduction to 1/2 output power to 1/3 output power is a preferred embodiment, and is not limited thereto, as long as the user can obviously feel the difference in output power and has a prompt effect. Just fine. Following the above description, the state of power failure or power-off is released, that is, power is restored from the power terminal 221, as shown at time point T2 of Fig. 5'. The trigger pin Pin of the microcontroller 22321 detects that the power signal input by the power terminal 221 is 'Ή', so that the first output pin Pout1 and the second output pin pout2 both output the off signal 22324 to The first transistor 22322 and the second transistor 22323, the off signal 22324 is such that the first transistor 22; 322 and the second transistor 22323 are not turned on. At this time, the microcontroller 223.21 and the light The power of the diode unit 21 is restored from the power terminal 221, and the LED unit 21 is restored to the original output power. The pulse width modulation control unit 2233 outputs the power signal 2211.
