As an optional implementation manner, fig. 3 shows a specific implementation flow of the electrical interruption delay control method S103 in fig. 1, please refer to fig. 1 and fig. 2, where S103 specifically includes:
s1031: and adjusting the supply current of the emergency electric energy according to the first pulse adjusting signal, and outputting the adjusted supply current to the light-emitting module within a first preset time period so as to control the light-emitting module to emit light within the first preset time period.
Specifically, when the dial switch is adjusted to a first gear according to a first gear adjusting instruction and a power failure event occurs to the light-emitting module, emergency electric energy is accessed, a first pulse adjusting signal is generated according to a power failure signal output by the light-emitting module, flexible dimming is performed on the light-emitting module in a power failure delay process through the first pulse adjusting signal, and once the power failure event occurs to the light-emitting module, the light-emitting module can automatically delay for a period of time to emit light after the power failure through the first pulse adjusting signal; therefore, when the dial switch is not adjusted to the second gear and the third gear, the timing delayed light emission is automatically carried out after the power failure event occurs to the light emitting module, the light emitting module is electrified and emits light in the first preset time period so as to meet the delayed light emission requirement of a user, and the light emitting state of the light emitting module can carry out high-efficiency and self-adaptive light emission; for example, the first preset time period is 2 minutes, and then after the power failure event occurs to the light-emitting module, the light-emitting module can still keep emitting light within 2 minutes, so that the light source display stability and flexibility of the light-emitting module are improved.
S1032: and adjusting the supply current of the emergency electric energy according to the second pulse adjusting signal, and outputting the adjusted supply current to the light-emitting module so as to control the light-emitting module to emit light according to the first preset light-emitting intensity.
When the dial switch is adjusted to a second gear according to a second gear adjusting instruction, when a power failure event occurs to the light-emitting module, emergency electric energy is accessed, and a second pulse adjusting signal is generated when the dial switch is adjusted to the second gear, so that the light-emitting intensity of the light-emitting module after power failure delay can be adjusted through the second pulse adjusting signal, and the light-emitting module can emit a light source with specific brightness according to the visual requirements of a user in the power failure delay process; for example, when the light-emitting module loses external electric energy, the emergency electric energy is started to carry out emergency power supply on the light-emitting module, the light-emitting module is connected with the emergency electric energy with specific power supply current in the delayed power supply process so as to finish accurate control on the light-emitting brightness of the light-emitting module, and the light-emitting brightness of the light-emitting module has flexible adjustability.
S1033: and adjusting the supply current of the emergency electric energy according to the third pulse adjusting signal, and outputting the adjusted supply current to the light-emitting module so as to control the light-emitting module to emit light according to the second preset light-emitting intensity.
Specifically, after the dial switch is adjusted to the third gear according to the third gear adjusting instruction and the light-emitting module has a power failure event, emergency electric energy is accessed, a third pulse adjusting signal is generated when the dial switch is adjusted to the third gear, and then the light-emitting state of the light-emitting module can be changed in real time through the third pulse adjusting signal; when the dial switch is in a third gear, the light-emitting module performs self-adaptive light emission at a second preset light-emitting intensity so as to realize the power-off delay light source control function of the light-emitting module; the dial switch is adjusted to the third gear, so that the power-off delay light-emitting brightness of the light-emitting module can be accurately set, and the light source adjustment flexibility of the light-emitting module in the power-off delay process is guaranteed.
It should be noted that, when the dial switch is in the neutral position, the light-emitting module can automatically perform delayed light emission within a certain time period; when the light emitting module is in a power-off state, if the dial switch is adjusted to the second gear or the third gear, the dial switch is not in the neutral position, and then the light emitting intensity of the light emitting module is preferentially adjusted according to the second pulse adjusting signal or the third pulse adjusting signal.
Optionally, the first preset luminous intensity is different from the second preset luminous intensity; therefore, the gear of the dial switch is changed in real time, the light emitting state of the light emitting module in the power-off delay process can be changed, the light emitting brightness and/or the light emitting duration of the light emitting module can be accurately adjusted by utilizing various pulse modulation signals, the adjustment flexibility of the light emitting state of the light emitting module is improved, the diversified light adjusting control requirements of users are met, and good use experience is brought to the users.

s1021: and detecting whether the power supply port of the light-emitting module has a level falling edge pulse.
The light-emitting module is used for accessing external electric energy through the power port so as to realize the power supply stability and power supply safety of the light-emitting module, and when the light-emitting module accesses the electric energy through the power port, whether level falling edge pulse occurs in the electric energy input by the light-emitting module is detected so as to accurately and efficiently judge whether a power failure event occurs in the light-emitting module; therefore, the actual power failure condition of the light-emitting module can be accurately judged by detecting the level fluctuation condition of the power port of the light-emitting module, and the detection steps and the control flow of the power failure event of the light-emitting module are simplified.
S1022: and if detecting that the level falling edge pulse occurs at the power supply port of the light-emitting module, judging that the power failure event occurs in the light-emitting module.
S1023: and if the power port of the light-emitting module is detected to have no level falling edge pulse, judging that the light-emitting module has no power failure event.
When the power port of the light-emitting module has a level falling edge pulse, the light-emitting module is disconnected from external electric energy, and at the moment, the light-emitting module needs to be started to supply emergency electric energy, so that the light-emitting module emits a corresponding light source in the power-off delay process; when the level of the power port of the light-emitting module is always maintained in a stable state, the light-emitting module is powered by external electric energy, a power failure event does not occur in the light-emitting module, and the light-emitting module can emit a stable light source; for example, when the power port of the light emitting module is connected to 3.3V of high level electric energy, it indicates that the light emitting module is powered on to emit light through external electric energy, and the power port of the light emitting module is in a high level state; when the falling edge from 3.3V to 0V of the power port of the light-emitting module is detected, indicating that the power failure event occurs in the light-emitting module; therefore, the power failure event detection function can be accurately finished by detecting the level fluctuation condition of the power port of the light-emitting module, and the power failure delay control step of the light-emitting module is greatly simplified.

Therefore, the embodiment sets the corresponding light emitting mode for each gear of the dial switch in advance, and then the light emitting state of the light emitting module in the power-off delay process can be adjusted in real time by adjusting the gear of the dial switch, so that the light source control efficiency of the light emitting module is improved.
