www.kitszone.com AC Led Circuit Diagram The circuit given here uses a super-bright white Light Emitting Diode works on 230V AC with minimal power consumption. It can be easily assembled on a general purpose PCB. It can be used as garden lights indoor lights panel lights etc. Good quality Super-bright LEDs available in the market costs about `7 to `10.

www.kitszone.com AC Led Circuit Diagram These LEDs emit a 1000-12000 mCd bright white light like welding arc and works on 3 volts. The forward current of each LED may vary from 20mA to 120mA. Their maximum voltage is 3.6 volts. Anti-static precautions should be taken while handling these LEDs. In this circuit I have used 40 numbers of 8mm straw hat LED with a forward current of 120mA.

This circuit employs capacitive reactance for limiting the current flow through the LEDs on application of mains voltage to the circuit. If we use only a series resistor for limiting the current with mains operation the limiting resistor itself will dissipate around 2 to 3 watts of power whereas no power is dissipated on using a capacitor.

The 390- kilo-ohm ½-watt resistor acts as a bleeder to provide discharge path for capacitor C1 when mains supply is disconnected.

The circuit can be enclosed in a LED panel case as shown below and can be connected directly to 230VAC through a wire. A series combination of 40 LEDs gives a luminance lux equivalent of a 40W bulb.
