How to connect LED with 220V AC

In this toturial, We are going to explain  how to connect LEDs with 220 Volt AC directly with the circuit diagram and resistors values. we have already explained how to design a transformerless power supply LED 220V AC circuit with calculation.

 

Required components for this 220V LED circuit:

1. 56k 0.25-watt resistor
2. 1N4007 Diode or bridge
3. 5-mm LEDs 3V
4. Zero PCB
5. We can also design it without PCBCalculation for Transformerless Power Supply

Working Explanation

The anode of the IN4007 diode to the negative point of and LED. The cathod of Diode is connected directly with main supply. The negative pin of LED is connected directly with the 220v AC main. In 2nd circuit we have connected a multicolour LED directly with 220v AC. Both circuit are very easy to understand and 100% working circuits.

In Multi color LED we have used a Capactior with LED points and after diode and resitor.

LED Blinking on 220v AC directly

Components Required for LED blinker directly with 220 volts AC

• LED
• Diac DB3
• Diode IN4007
• 470k resistor
• 1k resistor

Diac DB3 Diode Alternating current

DIAC is a device from the thyristor family. It abravation of Diode Alternating current. It works both reverse and forward bias and it works during a positive half-cycle and also during a negative half-cycle of the AC waveform.

DIAC is an electronic device from the thyristor family. DIAC is an aggravation of Diode Alternating current. DIAC works both reverse and forward bias and it works during a positive half-cycle and also during a negative half-cycle of the AC waveform.

Applications

• Some times we have to show presense of main supply then this is very useful.
• It can also be utilized in the indicator circuits that use AC power.
• The circuit can be used in the home lighting system.
• Or for any AC circuits that require indication.
• In homes, it can be connected with the doorbells, etc
