Leds in parallel

[slytherock]

possible mod with led.

how to put 6 led on the same current

brieve description of led circuit:

single led: Only one led connected ( lol )
serie leds: all leds connected one after the other (neg from one to pos of the other)
parallele leds: All pos of the leds connected together and all neg of the leds connected together.

(Btw; Metku have a nice led calculator...) (http://www.metku.net/index.html?path=mods/ledcalc/index_eng)

As you can see all the leds are placed like a spider web

On the next photos, you can see why; they are connected in parallel, so all the + and all the - are together

For that case, I needed more lights than the leds could, so I place old CD's behind them
