230v LED Driver Circuit

In this project, we have designed a simple 230V LED Driver circuit, which can drive LED directly from the mains supply.

230v LED Driver Circuit Diagram

Components Required

• 2.2µF Polyester Film Capacitor (225J – 400V)
• 390KΩ Resistor (1/4 Watt)
• 10Ω Resistor (1/4 Watt)
• Bridge Rectifier (W10M)
• 22KΩ Resistor (5 Watt)
• 4.7µF / 400V Polarized Capacitor
• 10KΩ Resistor (1/4 Watt)
• 4.7V Zener Diode (1N4732A) (1/4 Watt)
• 47µF / 25V Polarized Capacitor
• 5mm LED (Red – Diffused)

Advantages

• With the help of this 230V LED Driver Circuit, we can drive LEDs directly from the main supply.
• This project is based on a Transformer Less Power Supply. Hence, the final build won’t be a large one.

Applications of 230V LED Driver Circuit

1. This circuit can be used for home lightening systems.
2. It can be used as an indicator circuit.
3. One can fix this circuit with the door bell to give indication.

Limitations of 230V LED Driver Circuit

1. Since 230V AC supply is being directly used here, this circuit can be dangerous.
2. This circuit is best suited for domestic applications using single phase supply.  This is because, in case of three phase supply, if any of the phases accidently touches the input terminal, it can prove to be quite dangerous.
3. The capacitor can produce spikes at mains fluctuations.
