How to Connect 4v LED Light to 220V AC | SekhoHub
In this video I’m making a power supply to drive a 4V led on mains 220V. I am using the cheapest solution for this and that is making a transformerless power supply. So in this video I made the power supply be very careful because this circuit uses high voltage so don’t touch it it is better to cover this circuit in insolating case or something similar.
Materials for the Project.
- 4V led light
- 100uf 50v capacitor
- 1uf nonpolar capacitor (105 capacitor )
- 1 Ohm 3W resistor
- 1M Ohms resistor
- 1N4007 diodes
