Hi folks,
So my wife wants me to build her a light box, so she can stencil over a light source, rather than doing it against the window.
I made her one with a energy saving bulb, but it got to hot.
I took apart a led torch apart and used the 4 LEDs that had, but it was only bright where the bulbs were.
So now I want to start again.
The box is about 10 inches by 7 inches, and I don’t mind if it’s powered by batteries, mains or dc.
So.....
1) if I wanted to build a grid pattern of LEDs, about 1/2 to 3/4 of a inch apart, what’s the best way of wiring them up? Should I use a ‘chip’ of some sort? What about using an Arduino?
2) What ‘white’ led is best for brightness? Eg warm white, cool white, bright white??
I have seen piranha LEDs with 4 legs on them, should I use these? Ordinary 2 leg ones? Straw hat ones? I would rather a focus LED rather than a wide angle one.
3) I have seen rather nifty edge lit light boxes, but have no idea what they are using or how easy that is, so might just stay with the LEDs for now.
4) any other things I should be looking out for?
Looking forward to your suggestions, and possible wiring diagrams.
Jon.
