DIY Radeon clone?

Every led has a particular voltage that it has at a particular amperage.
Take the 4 blues. Each led has 3.5V across it.
Run 4 in series +..-..+...- ect you add the voltage up or multiply
4 x 3.5 = 14V
Put 4 sets of 4 in series.. that is 14 x 4 = 56V
That is the voltage needed to run all 16 leds in series.
And say for the blue channel with 16 leds now in series and at 700mA (your choice) that string is
56V x .700A = 39.2 Watts


I took the MAX voltage listed as a safety feature.


Repeat for every other color..

Can I use this Led driver for each channel with two discs in series?

Running 4 in series AND controlling each of 7 channels individually is going to be expensive.
56v blue
56V white
56V violet
28V green
28V UV
18.4v Red
10.4v Yellow

7 Meanwell LCM-60U drivers.
2-72V @700mA

2 of these would work if you combine some of the channels and run 2 "sets" of pucks.
(1) 28v
(2) 28v
(3) 28v

(4)14v
(4)14v
=28V

(5)18.4v
(5) 10.4
= 28.8V

combining red and yellow is probably fine
green and UV is a bit odd but as is there would be no choice
36V power supply 200W or better to run BOTH of the arrays.
So all 4.

Any channel that is between 23 and 42 volts
which is only blue, white, and violet.

 

[danielch2008]

Qualquer canal entre 23 e 42 volts
que é apenas azul, branco e violeta.

Thank you. I missed you here in the forum.
