Can get more addictive ..Can it ?

[stardustsailor]

Yeap..
...
Well...

Making D.I.Y. solid state grow lights-and boasting about it !!!- has become as addictive as growing itself ..
Or might a tad more ?

So ..
Where was I ?
Ah,yes ..


I'm buiding poor myself a new 'dual COB' light ..
( I 've to ..I 've no single light to my ownership right now ...)
My second of the -so called -" V series " ...

The light's progress so far ...
(For those interested at D.I.Y. designs ,at least ... )

The outer top-front looks ...


A corner -spot on ...


The rear end ...



The " tin " wide open...



The 'inner plate " full loaded and pre-wired ..
(heat sink not shown )


A detail ..



The drivers are placed ,slightly to the front end of the plate .
That for 'balancing ' the weight of the rear plate- carrying the small Meanwell 12 VDC PSU ,the power outlet
posts and the EMI filter/AC input socket .


The rear plate ,from the inside ...
(half-wired,DC side only )




And that is -most of - the basic design ,of the " V series "dual COB lights .
Either utilising CXA3070 or Vero29 L.E.D. arrays ...

Cheers.


...
So addictive ...

Hello my name is positivity and I am a diy addict..
I keep ordering parts for lights i dont need..lol

 

[alesh]

Amazing work. Could you please post a photo from the COB side?

 

[DonPetro]

Amazing...i haven't even built a light yet and im already addicted...fiending all the time.

 

[bicit]

What ever it is, it can be improved. It's a pretty deep rabbit hole into wonderland.

 

[stardustsailor]

Amazing work. Could you please post a photo from the COB side?

Still under construction ..








Cheers.

And the two most popular COBs in Sketch Up models.
(.skp file in zip folder )

-Models are converted from original cad/mesh files ,provided by manufacturer -(STEP files).
SimLab STEP importer was used ,for converting STEP cad files into 3D sketch up models.

http://www.simlab-soft.com/3d-plugins/STEP_Importer_For_Sketchup-main.aspx

(Also a IGS / IGES file importer ,as plenty of electronics 3D models are provided in .igs file :
http://www.simlab-soft.com/3d-plugins/IGES_Importer_For_Sketchup-main.aspx)

Follow the simle free-trial licencing ,for 15 conversions of STEP (or IGES ) models.

Cheers.

Hmmm....


Probably that's the best possible placement ..


After doing some thermal simulation ,at least ..
(with a heatsink as similar to the one used ...
|Could not find any other ...The actual heatsink used weighs 1990 grams and it has 16 thicker fins ,as also twice as thick base ,than the one used at the simulation.Still ,the sim assumes of 100% full contact of COB thermal pad- TIM -heatsink surfaces .So taking account the plus from the one side and the minus from the other ,the sim most probably represents quite good the real-life results ..)


If the COBS were 2cm (20 mm ) closer to each other ..,
{ 80 mm distance from center to center of the square thermal pads ,instead of 100 mm )
Then ...

....


...
So ...
Drill time !!!


(Again ....... )


Cheers.

 

[stardustsailor]

Hmmm...
Seems Mr."Faster than light ,e fuctrion from old times " is right .....










So ...
Be it ...




The new -age High Intensity ....Diodes ...light ...

Still some ( booooooringgggggg ) wiring -job to be done ...



Thanx...Tin of salmon...
Myself tried ,once to suicide ..Took pills ...
Plenty of them ...
I mean plenty ...

..Dam' hard job to die ,with multivitamins (+ minerals )...
The artificial raspberry taste they had ,almost killed me though...
Didn't work out back then,never tried it ever again ...
Diarrhea also,was awfull ..Something not to remember ,but I can't ...

So...
As my big fat momma says :

" Stay on the prescription ,cut off the BS."

Cheers.

That's a funny story and I hope you don't mind me making light of it... Your craftsmanship is as sharp as ever! One of these doing work in my tent would be too much fun.

 

[THE KONASSURE]

Yay you went with the bridgelux lets see what this baby can do

 

[stardustsailor]

I've became a ...fan of large diameter fans ...
(they push serious amounts of air ,with as low power dissipation as 1 Watt !
And as silent possible -cause of their low rpm )

Noctuas are pretty good and really silent ..
But quite expensive...
And my favourite model (NF P-14 FLX ) is discontinued ,and I don't like the Redox series model .

NF A-14 FLX is very good ,too...
But has not that fantastic and convenient circular frame ...

Still, I consider those three-much cheaper than Noctuas - alternatives ...

1) Thermalright TY-141

2) Thermalright TY-150
http://www.thermalright.com/html/products/fan/ty-150.html

3) Phanteks PH-F140HP
http://www.phanteks.com/PH-F140HP.html

|Any experience with any of those three fans ,anyone ?
(Not likely ,but you never know.. No harm done to ask ,anyway ..)

Thanx .
Cheers.

Nice light is the control on the front to a potentiometer that controls the intensity of the cobs? I also have not seen drivers like that before are they different to mean well ? Really swish looking light. Thanks for sharing.

 

[Mechmike]

Real nice engineering job! Simple, elegant and powerful.

Yes ,it is a common dimming function .
Will be set to 300 mA - 2100/2200 mA range .
(drivers rated as 1.95 A Io max ,but they output close to 2.2 A

Min limit is set by the small blue Bourns trimmer at the pot ,
while max limit is set at each driver -they have trimmers for Io mx & Vo max ,
as also maxing out Vo trimmer
sets the drivers from Consrtant current mode into Constant voltage mode .

Seriously ?
You 're not aware of the 'enthusiast's DIYers naked- HLG ' series ?
The HLP series ...

[PigTrotter]

Ha cool no i was not aware of the driver i will take a close look at it and get to grips with the information you just sent my way Thanks

 

[stardustsailor]

well....
Last things of wiring job ,are completed & finished ...

(blue paint over circuit boards is Teslanol T7 electrical isolation specialty varnish )

The COB wiring is soldered .( SAC -SnAgCu - Lead-free solder alloy used in every solder joint )


The hood is in place ...


And ...


Working with Veros is like vanilla cream ...
Growing with 'em ,is even sweeter ..


Cheers.

 

[salmonetin]

...... great work... as usual... like these tin version... ...version plateada...

saludos

Thats about the nicest led light I've ever seen. Amazing work..

I like it much better than the noctua colored version. Although the retro color scheme has its own fans too I'm sure..

I have one of the noctua flx, 140 mm nice fan well made and quiet , but I was not impressed with the cfm\static pressure. I'm thinking of running it at 15V instead of 12V.

Since then I picked up a couple of rosewill hypobera, decent pricing and check out the air pressure!
Fan Size: 140mm

• Bearing Type: HDB (Hydro Dynamic Bearing)
• RPM: 600 -1300 RPM
• Dimensions: 140 x 140 x 25mm
• Max static air pressure: 2.76 mm H2O

and oh btw do you know how to hook up an led to the tach wire so I can visually see that the fan is working ? My understanding is connect a resistor plus led from 12Vdc to the yellow tach wire But I don't know what ohm resistor and what led to use for a nice bright strobing signal.
