HELP: Wiring LED's

SgtGoldy · 04-08-2012, 09:18 PM

Hey guys, I'm looking to preform an IRON MAN look to my light housing using Piranha 5mm LED's. I was wondering if anyone had any insight on how to wire these up. I am experienced with soldering but not really working with LED's. I have no idea what I need or how to wire them up in general. Any information is appreciated.

What color are the LEDs and how many are you trying to wire up?

Input voltage is between 12 and 14.4v, so I usually average it out to 13.8V for my calculations (conservative). You need to look at the spec of the LEDs to see with the forward voltage (Vf) is, which is usually around 2.2-3.5v. Then there's the driving current which ranges from 20-70mA. From there you'll be able to calculate the required current limiting resistor.

Look up online for LEDs and calculators.

Piranha LEDs are 4 terminal, each pair on one side are of the same polarity. These LEDs have 4 terminals for improved mechanical stability on PCBs.

Its a cool white. Each headlight will have 10 leds. Thanks for the info too

No guarantees, but you may be able to wire up a string of 5 LEDs in series. If that doesn't work try 4. Then you can connect the strings in parallel and use a single resistor. That is the quick and dirty way to get the job done.
