Sounds like something to do itself.
Ohm's Law says:
E = I x R
You have to find the specifications of the LED to be used. This will give the maximum voltage LED.
If you have tension, shows the sheet of current for maximum brightness.
Now you have the voltage and current.
Calculated with the voltage (E) and current (I), the resistance (R)
Therefore, LEDs. Now you can wire in series / parallel equal to the supply voltage.
