So I have serial connected 8 LiPo's with corresponding controllers to monitor the battery pack. Now, they deliver 32 volts which is precisely what I need but they deliver way to much amperage compared to what the LED can handle.
The LED specs for input is 32-34V and 3500mA.
So I got reccomended to build/buy a "Buck driver" which looks promising, but I don't know how to calculate the different components and I'm way to much of a beginner to figure it out on my own, so i found a calculator that points me to a list of items that might be suitable.
Problem here is, non of the datasheets mention the range of the amps the circuit can limit within. I would feel much more confident if they mentioned it somewhere before I go about my "learning by doing" quest.
I have no clue where to begin or if the products are correct, I've read up a bunch on buck converters, Constant-current diode's and what not.
I got an example to me saying something like "Lets say you have a car. To maintain the speed you need to have a car that can go fast enough, and a cruise control to set the correct speed", I assume the car is the LED and the circuit I'm looking for is the cruise control. However, this confuses me since the power supply and the LED is already agreeing on the voltage, I don't need a cruise control I need a fan for the bloody engine so it doesn't overheat?
I need help, in any shape or form so I'm turning to the guru's of stack-exchange!
Edit: I've Googled for 4 days and asked engineering friends, and just as I post this I find: http://homemadecircuitsandschematics.blogspot.in/2011/12/make-hundred-watt-led-floodlight.html
Not sure that works for my setup either tho.. I'm so confused by now..
