s1, detecting whether the lamp is powered down by the CP pin of the single chip microcomputer;
and the CP pin of the singlechip is connected to a circuit of a driving power supply of the lamp.
And S1-1, if the power failure is not detected, continuing to execute the detection program, and continuing to maintain the existing working state of the lamp.
S1-2, if the power failure of the lamp is detected, the single chip starts an internal timer to start timing; meanwhile, the singlechip stores the working mode of the lamp in the memory when the lamp is powered off;
the memory also stores a plurality of working modes corresponding to the lamps, for example, the working modes of the lamps are full-bright, half-bright, yellow and off in sequence.
S2, after the timer begins to time, the single chip microcomputer CP pin detects whether the lamp is electrified again;
s2-1, if not, the single chip continues to detect whether the lamp is powered on;
s2-2, if the lamp is electrified again, the single chip microcomputer judges whether the timer reaches the preset time when the lamp is electrified again; the preset time is preset by factory or set by a user;
s2-2-1, if the timer reaches the preset time when the lamp is powered on again, the lamp enters the working mode when the power is off last time;
for example, the working modes of the lamp are full-bright, half-bright, yellow light and off in sequence, if the working mode during power failure is half-bright, the lamp is powered on again, and if the timer reaches the preset time, the lamp enters or enters the working mode of half-bright.
S2-2-2, if the timer does not reach the preset time when the lamp is electrified again, the lamp enters the next working mode when being electrified again;
for example, the working modes of the lamp are full-bright, half-bright, yellow and off in sequence, if the working mode during power failure is half-bright, the lamp is powered on again, and if the timer does not reach the preset time, the lamp enters the next mode of the half-bright mode, namely the yellow mode.
According to the lamp working mode synchronous control process, the time for accurately controlling the lamps to switch the working states by starting the timer after the CP pin of the single chip microcomputer detects the disconnection of the commercial power signal of the lamps is increased in a software sub-control mode, so that all the lamps can enter the same working mode at the same time under the condition that one panel switch controls a plurality of lamps, and the working consistency of the lamps is ensured.
Besides the above-mentioned accurate control lamps and lanterns output mode of working through the software mode of the one-chip computer, the invention has also increased if the multiple lamps enter the working mode and out of step, if the lamp I outputs the module A to light alone, and the lamp II outputs the module B to light alone or AB lights totally, etc. situation, can pass the wall switch of fast continuous switch to reset the working condition of all lamps and lanterns forcibly, the switching speed here is very much faster than the normal switching speed, this kind of force reset function can guarantee lamps and lanterns recover to the same working mode presumed in unison, the interval time of specific switch and number of times are debugged by hardware circuit and software program together, guarantee the uniformity of the working condition of the lamps and lanterns when the multiple lamps are connected in parallel even more.
Fig. 4 is a schematic diagram of a voltage detection circuit according to an embodiment of the present invention.

The voltage detection module is configured to detect the voltage of the CP pin, and when the voltage of the CP pin is detected to be about 5V, the lamp is in a power-on state; and when the voltage of the CP pin is detected to be 0V, the power failure of the lamp is indicated.
When the voltage detection module detects that the voltage of the CP pin is 0V, the voltage detection module sends a lamp power-down signal to the processor, the processor stores a working mode of the lamp before power-down into the memory, and a timer is started to start timing;
when the voltage detection module detects that the lamp is powered on again, the voltage detection module sends a signal of powering on again of the lamp to the processor, the processor judges whether the timing time of the timer reaches the preset time or not when the lamp is powered on again, and if the timing time reaches the preset time, the processor controls the lamp to enter a working mode when the lamp is powered off last time; and if the preset time is not reached, controlling the lamp to enter the next working mode by the processor, wherein the preset time is preset by factory or set by a user.
For example, the working modes of the lamp are full-bright, half-bright, yellow light and off in sequence, if the working mode in the power failure is half-bright, the lamp is powered on again, and if the timer reaches the preset time, the lamp still enters the same working mode as that in the power failure, namely, the half-bright mode;
and if the timer does not reach the preset time when the lamp is powered on again, the lamp enters the next mode of the working mode when the power is off, namely the yellow light mode.
