Circuit operation principle：
When switch SW moments in an ON state, cell voltage is charged to C1 by R1, due to C1 capacity it is less, Q1 base stages
Voltage reaches 0.7V soon and then turns on；As resistance R1 resistances are larger, now Q1 is operated in amplification region；After Q1 conductings, Q2
Base stage is changed into low level, and Q2 is also switched on, and battery is powered to lamp bead by Q2, and lamp bead starts to light；Due to driving current
Limit, Q2 now can not be fully operational in saturation region.After Q2 conductings, power supply is charged to C2 by R3, thus electric current
C2 to Q1 base stages are flowed through, Q1 there are enough base currents and enters into saturation region operation, Q2 also follows saturation conduction, now lamp bead
Reach high-high brightness.After C2 is fully charged, due to not having enough base currents, Q1 and Q2 to exit saturation, electric capacity C2 is just
Pole tension is higher than Q2 collector voltage, so electric capacity C2 is discharged by resistance R3 and R4, at the same time Q1 base currents
It is pumped due to the electric discharge of C2, Q1 cut-offs, Q2 are also switched off, and lamp bead is changed into OFF state；After electric capacity C2 is discharged, power supply is again
Secondary to provide starting current for Q1 by R1, circuit is reworked again, and Q1 and Q2 conductings, lamp bead are lighted again, are so circulated, are reached
To the effect of flashing light；Change the big frequency that can change flashing light less of electric capacity C2 or R3.
Circuit structure of the present utility model is simple, be controlled by flashing light control circuit when using, and LED is continuously followed
Ring light on and off, so as to reach the effect of flashing light, which can meet the use demand of different LED, while which uses electronic devices and components few,
