Different collor high powered 3 watt led strings on one constant current power supply? Answered
Can i connect 3 different collored led strings to one constant current power supply?
This is my power source, gives min 9v and a max of 48v @ 700mA
Mean Well LPC-35-700
My leds all 3 watt
6 x 630nm red - 2.5v/3v - 750mA
2 x 660nm deep red - 2.2v - 700mA
2 x 460nm blue - 3.4/4v - 750mA
Can i create these string?
1 string with 6 x 630nm = 18v @ 700mA, should have no problem to run, right?
1 string with 2 x 660nm = 4.4v (9v min from power) 9v - 4.4v = 4.6v / 0.7mA= 6.57 ohm resistor i should add to this string, correct?
1 string with 2 x 460nm = 6.8v (9v min from power) 9v - 6.8v = 2.2v / 0.7mA = 3.14ohm resistor i should add to this string, correct?
Can my power supply handle this? Since it changes voltage.
If i can use this, which watt resistors would i need?
I would also for example like to add 1 potentiometer for the 460nm blue leds
And add 1 potentiometer for the 660nm deep red leds
Am i asking to much here or can this be done?
