Simple Dimmable LED setup?
A friend of mine has a project which involves using a large amount (40+) standard 5mm LEDs to light a frame to a uniform brightness with the ability to dim the entire setup uniformly. Due to the shape of this frame its not economical or practical enough to use strip lighting.
Rather than try to explain the circuit design I came up with I have included it as an image.
Essentially I'm worried that I've overlooked something in this design and was wondering whether anyone with more experience would be able to take a look and point out any problems I've missed.
If anyone has the time I would be incredibly grateful.
