Title: Superbright led's is there a guide on wiring and what i need to do?
Post by: Marky_1979 on February 11, 2005, 08:18:27 am: I have bought some superbright led's from e-bay in the hope of lighting my coin door and trackball red for the door and blue for the ball. I have a spare psu form an old pc and was thinking of using that to power the lights.

Now not know ing anything about wiring i was wondering where to start and what consideration i have to take into account i know nothing of electronics and wouldnt even know which wires to use or what to do with them.

So i guess im asking for an idiots guide to this problem. Pics would be very helpfull.

Many thanks - Marky :)

The main issue is that you will need to add a resistor to your LED so that it doesn't blow up. There is a calculator in that link to determine what ohm resistor to use depending on what voltage your power supply is and what voltage your LEDs can handle (i.e. what color/type they are).

Now, I'm not an electrician, but - my super bright LED's are 12v, just like the yellow wire from my computer's power supply. Marky - you didn't say what the power requirement was for your lights. If they match your power supply, I don't see the need for resistors. I didn't need 'em, and you might not either.

Post by: TOK on February 12, 2005, 06:25:33 pm: I bought some 12v LED's at an auto parts store and wired them right into the 12v on my PC power supply like Gameover said. They're 3 for $5 and come in multiple colors. I can't see messing with resistors.

Post by: Voodooray on February 13, 2005, 07:18:24 am: It's a life span thing. The resister actually limits the current not the voltage. You can run them without a resister but if you use resisters they will last about ten times longer.

Post by: ShinAce on February 13, 2005, 09:09:58 am: The resistor limits both current and voltage. It just happens that current is more dangerous to an LED than voltage. But you need voltage to cause a current, so it's a catch 22.

It's a life span thing.

Run 12V thorugh 1.5v LED and the life span will be about 2 seconds.
Title: Thanks guys
Post by: Marky_1979 on February 14, 2005, 04:06:53 am: Thanks alot guy i appreciate the help, it think the power supply will be 12v and so will the leds so should be simple enough i think :)
