### Description:

In this project, I have explained how to connect LEDs with 220 Volt AC supply with the circuit diagram. I have also explained how to design a transformerless power supply LED 220V AC circuit with calculation.

### Circuit Diagram:

The LED 220V AC circuit is very simple and efficient. Here I have connected 8 LEDs (5-mm, 3V) in series and supply the circuit using a transformerless power supply.

### Required components for this 220V LED circuit:

- 0.22uF 400V AC capacitor
- 100uF 35V DC capacitor
- 560-ohm 1-watt resistor
- 1M 0.25-watt resistor
- 1N4007 Diode (4no)
- 5-mm LEDs (3V) (8no)
- Zero PCB

### Make the LED 220V AC circuit on Breadboard

First, I have made the circuit on the breadboard for testing. In the tutorial video, I have measured all the voltage with the multimeter to show how the circuit works.

### Tutorial Video on LED 220V AC circuit:

In this video, I have explained all the details for this LED 220V AC circuit.

### Calculation for Transformerless Power Supply

To design any capacitor drop transformerless power supply, first, we have to calculate the capacitance value.

**How to Calculate the Capacitance value for transformerless power supply?**

1. We should know the **input voltage** (Vrms) and the required **output voltage** (Vreq) and **current** (Iout).

2. Calculate the impedance (Z). **Z**=((**Vrms** X **1.41**) – **Vreq**) / **Iout**

3. Calculate the required Capacitance (C) value. **C** =**1**/ (**2** X **3.14** X **frequency** X **Z**)

I have explained in details in the tutorial video.

### Make the LED circuit on PCB

After testing the LED circuit on the breadboard, I have made the circuit on zero PCB.

### Place the PCB inside a Box

As, we are using 220V AC supply, so I have placed the PCB inside a plastic box to avoid any shock hazard.

Always take proper safety precaution while connecting 220 Volt supply.

### Finally!!

Now I can easily connect the circuit with 220V AC supply. Here I will use this LED circuit as a night lamp.
