Hey guys,
I am looking to wire up in parallel a group of 5 LED arrays, HLMP-2685. It's an LED block array that looks to have 8 internal LEDs. According to the datasheet, the specs on it are as follows:
Peak forward current per LED chip - 90mA
Average forward current per LED chip - 25mA
DC forward current per LED chip - 30mA
Reverse voltage per LED chip - 6V
When it says "per LED chip", is it referring to physically one LED array, or does that mean per actual LED in the array (since there are 8)?
If I need this circuit to run off 12 volts, would this be correct:
V = I * R
12 = .03 * R
R = 400 ohm
So, running them in parallel, I would apply at minimum, a 400 ohm resistor to each of the LEDs? Also, what would I use for resistors - a 1/2W, 1/4W, etc?
Thanks in advance.
