How do I power my LED's?
I have 50 Red LED's and 20 Blue LED's that I would like to make in an array for a grow light. I was thinking about gluing them with thermal glue on flat aluminum bars that are 2 inches wide in a rectangle with about 1 inch spaces around them because I don't have heat sinks. I think they would be able to dissipate enough heat if I use them in conjunction with a fan.
Here are the specs for the red lights (50):
2.4mV forward current
blue lights (20):
3.2mV forward current
If I'm correct, I need 84 watts for the Red LED's altogether; 44.8 watts for the Blue LED's altogether: combined wattage of 128.8 watts.
Previously, I stated that these lights were 3w, each. But I would rather save life on the diodes and run them at this lower power because they still give off a great amount of lumens.
Can anyone give me some directions on how I would construct this array? (what drivers to use, how to wire the LED's together, and how I could make the system plug into my wall outlet (standard USA socket)).
