220V Led Flasher Circuit Simple , Transformerless

There is a very simple flasher circuit transistor integrated 470k, 680ohm, 1n4007, 22UF, cardiac and led 470k resistor is not in my hand I used 560K

Diac Wiki

The DIAC, or “diode for alternating current”, is a diode that conducts current only after its breakover voltage, VBO, has been reached momentarily.

When this occurs, the diode enters the region of negative dynamic resistance, leading to a decrease in the voltage drop across the diode and, usually, a sharp increase in current through the diode. The diode remains “in conduction” until the current through it drops below a value characteristic for the device, called the holding current, IH. Below this value, the diode switches back to its high-resistance (non-conducting) state. This behavior is bidirectional, meaning typically the same for both directions of current.
