How to Make a 220V to 9-18W LED Driver Circuit.

In this tutorial, we will demonstrate how to make a simple LED driver circuit, which will work for 9-18w using a rectifier bridge, resistors, and capacitors.

    Components Required:

       1. Rectifier Bridge (DB107 or 1N4007 x 4 diodes) – Converts AC to DC

      2.  Resistors:

           560k  x  3 (For surge protection)

      3. Capacitors:

          105-335J/450V x 2  (High-voltage filter capacitor)

          4.7µF/250V  (Output stabilization capacitor)

     4. LEDs (9-18W, 300mA-600mA)

Circuit Working:

1. AC to DC Conversion

The input of 220V AC is given to a bridge rectifier (DB107 or 1N4007 diodes x 4).

AC is converted to a pulsating DC by the rectifier.

2. Filtering & Voltage Regulation

A 105-335J/450V capacitor (DC Link) filters and smoothes out the DC voltage. This allows the capacitor to break out safely when the power is turned off. One 560k resistor is in parallel. 560k x 2 Resistor for Input.

3. Output Stabilization

The DC output is stabilized via a 4.7uF/250V capacitor which dampens flicker/voltage spikes.

4. LED Connection

Output DC voltage (about 80-90V) serves to supply the series of LEDs (total 9-18W).

***Circuit Diagram***

Assembly Steps:

     1. Connect the 220V AC input to the rectifier bridge.

      2. Attach the 105-335J/450V x 2 capacitor after rectification.

3. Connect the two 560k resistors in parallel on both capacitors.

4. The DC output is where the 4.7uF/250V capacitor should be positioned.

5. After the LEDs are connected in series, test the circuit.

Conclusion:

This non-isolated LED driver efficiently powers 9-18W LEDs from a 220V AC supply. Caution: Since it’s directly connected to the main voltage, handle it carefully and use proper insulation.
