Principle circuit of AC strobe light

Probe current voltage pin 420*4450 head diameter 5.0 over current current and voltage pin

The strobe light can also be AC ​​powered, as shown in the figure, which is an AC powered strobe circuit. The R3 that adjusts the flash frequency is replaced by a potentiometer. The flash frequency is determined by the R3 and C2 parameters. The trigger switch S is also added to the circuit. When S is pressed, the strobe light starts to trigger.
