Optionally, for convenience of understanding, referring to table 1 above, the functional mode corresponding to the serial number 1 is a power-on slow start mode, and the MCU is powered on initially when the input switch is turned off, and outputs two PWM signals (PWM 1 and PWM2 are inverse to each other, that is, PWM1 is from 0 to 100%, and PWM2 is from 100 to 0%), and drives the lamp to turn on, and the lamp brightness changes slowly from 0 to 100%, and the time changes from 0 to 100% for about 5 seconds, if the input switch is turned off at any time of brightness change in 0 to 5 seconds, the MCU memorizes the brightness at that time (for example, when the input switch is turned off after 3S of brightness change is turned on, the PWM outputs 60%). When the input switch is closed again within 3 seconds after being turned off, the brightness of the input switch at the time of the previous turn-off is restored. And if the turn-off time of the input switch is more than or equal to 3S, then the input switch is closed, and the MCU initializes reset output.

For example, when the input switch is closed, the PWM1 is 100%, and the PWM2 is 0%; for the first switching state, 50% for PWM1 and 50% for PWM 2; the second switching state, PWM1 is 0%, PWM2 is 100%; the third switching state, PWM1 is 100%, PWM2 is 0%, and so on.
