How to Connect a 4V LED Light to 220V AC | SekhoHub
In this video I’m making a power supply to drive a 4V LED on 220V mains. 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 an insulating case or something similar.
Materials for the Project.
- 4V led light
- 100uf 50v capacitor
- 1 µF nonpolar capacitor (105 capacitor)
- 1 Ohm 3W resistor
