I am trying to build a high power RGB LED light. I am looking for 50W-100W range for the LED (all colors combined). 100W RGB LED desn't seem to exist so I am left with 50W, 60W, or 90W options. I would prefer higher wattage single LED module as it's cheaper than multiple lower wattage modules.
There is a suitable 90W LED module. There is no datasheet only this spec:
Voltage: R: 20~22V; G: 32~34V; B: 32~34V; Current: R: 900mA; G: 900mA; B: 900mA; Product size: 45mm x 51mm; Power: 90W; Wavelength: R: 620~625nm; G: 520~525nm; B: 460~465nm; 10 series and 9 in parallel;
I heard that for LEDs in series/parallel you need some additional components for current sharing etc... Do these LEDs have the required circuitry built-in making them essentially the same as a single LED in respect to powering them? Or do I need a special LED driver to power this module? Reason I am asking is because most LED drivers don't mention any specifics about series/parallel LED but I did recently see an LED driver with PWM control that specifically mentioned it's application was for LED module 1 x 50W multichip(10 Series x 5 Parallel). Does this driver have special circuitry or is it just a suggestion for what it can be used?
What do I need to look for in an LED driver in general other than constant current, min/max voltage range and power rating to be equal or lower to that of the LED. (For the 90" RGB LED, each color would use it's own 30W driver).
