38 led light with using bridge rectifier in ac supply
Hi @aamir6sh
It sounds like you’re working on an interesting LED project using a 38-LED array and a bridge rectifier with an AC supply! That’s a good approach, as the rectifier will help convert the AC to DC for the LEDs.
If you want to know about Rectifier Bridge, please visit the link Diode Rectifier Bridge.
I have a different design for LED circuits, and I think it might be helpful for you to take a look at it. I suggest reviewing the circuit layout to see if it can offer some advantages or improvements for your setup. Feel free to reach out if you have any questions or if you’d like me to explain the design further!
