I want to drive multiple 100W RGB LEDs but need information on how to do that.
Each individual color draws (with some variation) roughly 1/3 of that 100 watts. So, if I get a 100 watt constant current LED power supply, and hook it up to all 3 at the same time, all should be good and I'll get white light. Now if I hook up that same PS to just one of the colors, does it turn the LED into smoke or will the LED only draw the current it needs?
If the power has to be limited to the correct current for each color, how is that done in a way that I can switch the colors on and off individually? Does it take 3 power supplies? Can this be done with a single power supply that use PWM to control brightness? For example if 3 colors are on, 100% duty cycle is okay, but if only one or two colors are on the PWM would be limited to 33% or 66% respectively?
Obviously I need some help understanding the finer points of powering LEDs.
