Putting an end to flickering LED's on mains
It's the time of year when colorful twinkling lights adorning nearly every structure you can see. LED's have become more popular as of late, and from an energy standpoint that's good. I know most people can't see a 60Hz flicker but I can, and it's quite unpleasant to sit across from a tree full of LED's all doing the same on-off-on-off nonsense. I am fortunate to only get headaches though, other epileptics I've known have actually had AC LED's trigger seizures.
So what can be done about this? We bought LED strings before thinking about flicker and have since replaced them with incandescent ones, but I've still got all the LED strings in the closet. I'd really like to be able to use them. Perhaps I could fashion a device that acted as a middleman between the outlet and the plug on the lights that would smooth the incoming current?
I have two ideas for this:
1. Filter incoming current with an RC circuit
2. Rectify the mains voltage
I'm curious if anyone else has attempted, solved, or even just noticed this frequency problem? I don't mind re-inventing the wheel, but I'd rather not build it square.
Happy holidays! **yes, I just said happy holidays. Deal with it. :)
