DIY Radeon clone?

[danielch2008]

Cat 6 23 ga. fio deve funcionar melhor.

Pensou que estava colocando 4 em série?

Acabei de fazer um teste se ligaria o disco de leds. melhor será em série, isso?

OK, just be careful not to wreck the pads with the solder/un-solder cycle.
Also make sure they are at least on the heat sink. The diodes can heat pretty rapidly and get damaged.

How to solve the voltage peak problem on the electronic board when the board is connected to the source? I'm worried about burning the board.

 

[danielch2008]

I did a test with just a disk of LEDs connected to the DDLs, as I still can't dim the intensity of the LEDs, they stayed in full spectrum 100% on all channels. Then there was a doubt... the aluminum heatsink got too hot. I believe that this happened because it was without a cooler and at 100% of the light intensity.

Today arrived my board. In manual info Tell that need calculaded 3-5 volts less that panel.

I have 4 panels leds each panel in information in attach fules

I can put power supply of 48V and 2 A to two board of leds This Radeon Clone?

Err but difficult to understand but if you are referring to 2 of those in series, the largest channels are 14 volts so 2 x 14 = 28
Then add the differential of 3-4 volts.
32v or larger power supply.

You will only be able to put 2 in series.
You could run them in 2 x2 series/ parallel but that just splits the current



Now as to current...
W = V x A.
Calculate it for each channel and add

Well, she's mostly cleaned and buttoned up. Final load out is 8 Blue (700ma), Royal Blue (700ma), Cool White (350ma), 4 Mint (1A) 8 Violet (700), 3 HyperViolet (700), 4 395nm (700), 2 amber (700ma).

Now need to sort out getting pwm, gnd, and power to the fixture. I'm thinking cat6 for pwm, problem is I need 9 conductors to run 8 channels one to carry gnd . Easiest solution I suppose is to link two of the channels into one, maybe Blue and Royal Blue or Violet and HyperViolet.

As for connectors, maybe back to aviation connector for power and I suppose Cat5/6 for pwm signal.

Gotta fix those upper few wires, driving my OCD crazy.

What power supply to this project? O have two pucs but no mint and suplemento

14 (3*2)+ 7(2*2) + 2.6(1*2)+ 4.6(1*2)
* .700
2.19A
88.48w.
2.46A


36v 100watt(2.78) power supply
2 pucks in series 7 channels each channel at 700mA.

Your driver board only has 5 channels
However you do it . You add the voltages up of each led in the strong times the drive current.
That will get you the watts per string.
Add the watts up to get the size of the power supply.

I did put this power supply and BOOM . Crash

Neither the LEDs nor the driver board are very taxing on a power supply.
Actually all are quite passive.

If the power supply blew it was either at end of life or poorly constructed..

 

[danielch2008]

OK. What dimmer can i used to two pucs with 8 LDDs?

 

[danielch2008]

Can i used this power supply with 180w and 36V or will be issue

 

[danielch2008]

Have this too. What Will be a better?

 

[danielch2008]

Or i can Connect all 5 pucs inglês power supply de 56v and 240w?

 

[oreo54]

5?

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

LCM-U Series Mean Well 40~60W Multi-Output CC LED Drivers

$255...

3 in 1 DIMMING
0~10VDC, PWM, or resistance signal dimming function

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.

i did understand this volts and calculares ….

1) 28v
(2) 28v
(3) 28v

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

(5)18.4v
(5) 10.4
