220v led circuit schematic more leds can be added by reducing the value of r2 since the circuit is directly connected to mains take utmost care to avoid shock. The 47uf 400v capacitor at the input forms the heart of the circuit and functions as the main current limiter component of the circuit. 230v led express pcb layout. With 470nf the current will be 20ma.
