sooo im hoping someone here will finally be able to end my suffering with this crap. Sadly i get the feeling my answer is super easy, and im just super stupid soo please pardon my ignorance if this is the case. Now to the issue, im trying to design an array consisting of 125 3 watt leds, ranging from 2.5 Volts up to 3.6 volts.The leds im using have a rated typical forward current of 700mA. Ive tried a few online array wizards, but id much rather have a understanding of how it actually came up with the blueprints, this way if i wanted to make more, or something failed, id be able to handle the issue better. So after all of that, I know ill have to group the leds in a series based on its current voltage rating, but i guess what i would like to know,
1.How do i go about calculating the specs of the driver i am to use (output voltage, output current)
2. If i am to use a driver do i need to use resistors or a regulated power supply?
3. If i wanted to connect 42 LEDS, all with a forward voltage of 3.6 and a forward current of 700mA, in a array, how much forward current is needed to power all the LEDs?
thank you in advance to anyone who takes the time help me with this, it will be greatly appreciated
