hello everybody
i'm trying to build an IR illuminator to use with my security cam i need it to run with a DC power supply with a current of 60A the illuminator is made of 144 IR LED. i;m a beginner in electronics so could anyone please tell me the formula to use so i can choose my resistors? i have the multisim software but it's giving me lots of error and i can't know why although i have drawn my circuit correctly. so please any help is appreciated. the circuit is made of 36 parallel set of 6 IR led and a resistor in series . thx in advance.
