If only I still had that string of 120 red yellow and green LEDs I made when I was 14, I could show prior art and invalidate that patent!
I got curious. I knew series strings of 6 of those "old fashioned" panel indicator GaAs 2 volt LEDs would work at 12 volts, but wondered if I connected enough to equal 240 volts, would they work from the mains or just fail spectacuarly? I finally scaveneged enough LEDs and got up the courage to try it out. Thankfully it did work, though it was absolutely lethal as the diodes were just soldered in line with no insulation, trying to handle them while switched on was interesting to say the least! /ubbthreads/images/graemlins/ooo.gif I think I used the string for only a short while at the start of the Festive season, when the pins of a few LEDs broke off after trying to decorate a small tree with them, and I didn`t have any more. When I was 14, LEDs were still quite expensive to buy locally (1994) and there were no blue ones either. RadioShack (Tandy`s here) wanted GB£1 (US$1.65) for a pack of *two* diffused red or green 5mm LEDs! It wasn`t much better elsewhere.
