12 v DC 3watt led project
I am looking into an led project for my car.
It involvs using 3w led's and I have no idea on how to "drive" these for 12v dc.
I have looked into led driver's but they are a bit expensive in my opinion so I hope some of you electronic "guru's"
can assist me.
The specs are:
3w yellow led, forward voltage: 2.9-3.3v, forward current: 750 mA.
I have a very slight electronic knowledge background (novice at best).
I don't need a heatsink (don't think), as I will have 8 sections with 2 led's per section wired in series and they will be
mounted to an aluminum bar.
The led's will be connect to a chaser light controller circuit.
I just need to know what kind of resistors I need (and/or anything else).
The best way to describe my project is I am making a knight rider light for the front of my car.
I had posted on an electronics forum and got a suggestion to do this. The only problem is it didn't work.
