Ultraviolet LED with phosphor paint



Uploaded by: wbeaty
Video Description:
Got glow-in-dark paint? UV keychain flashlight? Combine the two. Imagine what you could build. Get UV LEDs from All Electronics or Electronics Goldmine. Get yellow-green "Night glo" Speedball(tm) fabric screen ink from art supply stores. (This is a very early test-video of mine from last April, shot in thumbnail mode.)

I have a 405nm (BluRay) laser which performs well for this function. I think I'll hunt out some of that 'paint'. I've been looking for a reasonably priced source.

Heah. Great video! This would be great for kids. My question is. If kids were playing with this and shine it in their eyes accidently can it damage their eyes?

It's a violet light (not actually UV.) Also, it's not as bright as the UV tube lamps sold for fluorescent posters (like Spencer Gifts.)

This actually helps in the idea of scrolling displays, you only have to rotate a plastic transparent shell (cylinder) and project the image from a stationary point. Many more options are available, but I think that a light buffer surely helps anyway.

It's actually just ... ( 8 months ago by wbeaty)
It's actually just violet light and not UV. It's all just advertising hype. If it was real UV, it would be invisible. And a real UV flashlight would be like germicidal merc vapor lamps, and have government warnings, and not be sold to the public. But even violet light can cause cornea irritation if you stick the LED against your eye for many seconds.
Well, this isn't ... ( 8 months ago by deviouslife)
Well, this isn't the type of Ultraviolet you're thinking of. It's not "ultraviolet", but its pretty close, ands has a lot of the same effects as ultraviolet, seeing as they are closer to the same properties as each other than red or green would be.
