Coming Soon ....

Xitanium 75W 0.7A AOCM 1-10V GL-Y sXt...

Wouldn't that limit the current ?
yes, and also the fan goes slower
you need a little bit more electronic to get it to work.

i´m also on the way to fire up my 50x90cm tent
bulding two bars with 4 Modules each.
a third one maybe later.
also i want use them for full cycle, so dimmable is a must.
voltage for one of my modules is less then 40V what makes things easy.

one big remote Power-supply
http://www.meanwell.com/search/nes-350/default.htm (max 3bars)

for each Modules
http://www.meanwell.com/search/ldd-hw/default.htm
very tiny ones, they are going in the Box between the modules

one power-cord into the tent, daisy-chain betwenn the bars

I have to agree with Spheda about remote driver box. Why not do this? It would also cut down the overall weight, those meanwell drivers are damn heavy even with plastic housing...

stardustsailor · Jan 31, 2013

WOW! ...

Ok ....

Super nice way of Driving ...

One question ..(might be silly ... )

- Have you estimated total driving eff ?

and ..ok ...a second one .....

Can you drive the fans with a tiny bit of these DC/DC converters ?

....
Bit more electronics .....

Wait a min ....

Say one ordinary 12 V psu of ..say 2 A max .....
2 fans each ,'using 0.3 A ....
0.6 in total ....

Say rest of it ( 1.4 A ) ..just say ....goes to resistance(s) (current limiter ) and SS relay(s) ....

Why the fans will turn slower ?
Still they get their 0.3A "share " .....

Where I'm not getting it ?

.. the Psu ,will supply the needed current to resistors/ SSR s' as a "device " ....
So if PSU ,has "enough" output A,to supply all "devices " (fans-ssR -resist. ) ....
Why the fans will turn slower ?

Ok .....
Now the design ,can change a lot .....
Without CC drivers ......
With a remote main power supply..
And tiny DC/DC CC drivers .....( these are the ones called " buck-drivers " ? )

Ok ....

Much smaller design .....

New one coming ....

Have to model first those tiny drivers ....

Ok ...

Good vinyl players have the motor & power supply , outside case ....

...Keep the music on .....

stardustsailor · Jan 31, 2013

I'' ll keep modelling some stuff ..
(leds ,ect ...) ...

S.Up is a really user-friendly program and with a lot of extra-free-plug-ins & add ons ...
Easy to learn and use ....
And ....
Very funny and somewhat more creative than Spolitaire or Dall of Cuty- Black Operator ....

And very-very helpful for all sorts of DIY planning and "virtual constructing " stuff....

Great freeware ....

For me, is just addictin' .....

Have you estimated total driving eff ?

powersupply has 87.5%
buckdriver has 97%

together we will see 87.5 X 97 / 100= 84.8%
Can you drive the fans with a tiny bit of these DC/DC converters ?
not with cc buck drivers, but there are also constant voltage buck driver
on the other hand, a fan(diameter 60-120mm) use most often between 1 - 3 Watt at 12 V or 100ma to 250mA
here we can use a analog voltage regulator such as 7812 or an LM317. with the last one we can freely change the voltage with two resitors.

btw. nice work in s.up

Οh ..Right ...
If you are so kind enough ,post an easy way to use the 7812 or LM317.
So ....With some buck -drivers and A CV buck driver ....

We can stick all the electronics under the hood of the "GD BASIC BOX"......

Bumping Spheda · Jan 31, 2013

^^^^ That's what I'm talking about.

Then attach some adjustable light hanger "anchors" to the panel so you can adjust the pitch, angle, and height all from two light hangers. Think of a hose clamp, hand adjustable. Does this make sense?

stardustsailor · Jan 31, 2013

Yup...I'm going to work again on single panels ....
But With GD box (GD=Guod's ) ...
Have to re-design everything ....
Even PCBs ....
I'm thinking 4 x 12 Oslons per heatsink ....
Anyway ....

Basic box ,uploaded also ...
Buck cc driver also ...
New heatsink model also (previous had a small-stupid- mistake )....

Should I make a simple model of a ssl led ?
(simple so if used in large numbers ,will not occur RAM issues ...)

But what's the point of modelling so small stuff ?

PCB design or lens design ?

....
Nevermind ...

stardustsailor · Jan 31, 2013

HEY-HEY-HEY!!!!!

THOSE are really TINY drivers ....
4 of those fit under the 25x25 side (top cover ) angle ....

W-O-W !!!!!

48V Power-supply

1. PWM circuit for dimming (30% - 100%) 100% = 700mA
2. FAN circuit (adjustable 7 - 12V)
3. Fail-safe for Leds (Leds off if Fan fails)

a simple model for the PCB (plate with two contacts) wil be enough (checking wiring)

stardustsailor · Jan 31, 2013

But .....
There's nothin' there ..

I can't see something ....

(checking wiring)...
Ah ..Ok ....

stardustsailor · Jan 31, 2013

I'm planning on having pcbs like the "petunia " ones ...
Same size ..
No lenses ,no on-board driver ,different choice of leds ...(80°)

So ..30x50 mm pcb with 12 SSLs ...
Simple ....

(I was thinking for one 60x50 with 24 leds split in two identical channels (for easier driving -finding driver )
But ,then ..better have spread 4 x 12ssl ( 30 x 50 mm ) pcbs , on the heatsink ....
So four modules per heatsink ....
12 leds each ...
10 whites (VF= ~ 3.1 average or calculate for more ? )
and 2 x 660 hyper reds (VF= ~ 2.1 average or calculate for more ? i.e 2.4 ..? )..
Each module needs ~35 V ?
If so ....
4 x LDD-H W(ire ) per GD box ....

PetFlora · Jan 31, 2013

If you arrange panels so that each row is staggered from the other, you will have Merkaba shape within every 4 rows

stardustsailor · Jan 31, 2013

Why I like so much the "Harley " colors ?

guod · Jan 31, 2013

point 1 to 3 are my part, get me a day or two for work this out.

red oslons at 700mA needs 2.45V
white ones at 700mA needs 3.3V
a good value for the Ldd-driver is 45V
we should use these values for calculation
so 12 Leds per driver will be no prob.

need some sleep now...

stardustsailor · Jan 31, 2013

Get some rest ,there ...
Great work ...
I'm deeply thankful ...

..
I'll stay up ...

No job to go to ,tomorrow ,anyway ...

At what wattage.... 1 w, 3w? 12 @ 3W would be 36W per panel :clap:
