Simple 220V AC LED Bulb Circuit diagram – Step-by-Step Guide
Assalamualaikum Everyone. I am @imranhassan

LED (light-emitting diode) light is a breakthrough innovation in lighting. It is much more energy-efficient, long-lasting, and environmentally friendly than other conventional lights, such as incandescent and CFL bulbs. LED light is basically a semiconductor device that converts electrical energy directly into light, resulting in relatively low heat generation and reduced energy waste.

Currently, LED lights are widely used in domestic, commercial, and industrial fields. Its main advantages include long durability, low power consumption, instant ignition, and a variety of colours and brightness. In addition, LED lights do not produce UV or infrared radiation, which is safe for the eyes and the environment. There are some important things to keep in mind when designing an LED light circuit, such as proper resistor selection, power supply management, and series and parallel connection techniques. In this post, we will discuss in detail a simple yet effective circuit of an LED light, which will be very useful for beginners.

| Now I will make a 220V AC LED light circuit diagram and explain how it works step by step. Let's see how I made it. |

1: Connect the power input and capacitor and draw the diagram:
I first connected the 230V AC power input. Since this voltage cannot be given directly to the LED, I used a 1µF 400V capacitor. It acts as a series capacitor and controls the input current. I drew the circuit part of the first step by hand, where the AC input and capacitor connections are shown.
2: Connect the resistors Draw the diagram of this step:
I used a 470KΩ resistor, which helps in reducing the inrush current. I also added a 100Ω resistor, which works to control the current. Here I have drawn the resistor connection part after the input capacitor.
3: Connect the bridge rectifier and draw the diagram:
Now that I have connected the bridge rectifier (4 diodes) to convert the AC voltage to DC, it produces positive and negative DC outputs. I have drawn the bridge rectifier part using four 1N4007 diodes.
4: Draw the diagram of the capacitor and resistor filtering part:
I have connected a 10µF, 160V capacitor, which smoothes the DC signal and provides a stable voltage to the LED. Here again, I used a 100Ω resistor to limit the current. Here I show how the capacitor and resistor together create a safe DC voltage for the LED.
5: I drew the diagram of the LED connection part:
Now I connected 24 high-bright LEDs in series. Each LED consumes about 3V DC, so I arranged the LEDs in several groups and connected them. Here I showed how the LEDs are connected in series and the current is flowing.
I drew the final circuit diagram:
After connecting everything, I successfully connected the LED circuit with DC output from 220V AC input and drew the LED circuit diagram together. And I took a selfie with my hand-drawn diagram.
| Conclusion: |

Thus I have made a 220V AC LED light circuit. It works like the LED bulbs usually available in the market. If anyone wants to try it themselves, they can follow these steps. I have drawn the diagram by hand, which will be easy to understand. I hope you like the post.
