Thinking of a new light ..

Pet,I promise you that ...
The next COB-HID design is going to be way more compact ...
I've already some ideas in my mind ...(and a joint in my mouth ...)

Only last 4-5 years lol

I get it now- a hps (sodium) killer

Cree pretty much has this as a high bay light. Good price, too

Have you thought about a dimmer?

I've thought for both the (available) common industrial applications of the 3000K CXA3070 Z4 and for the dimmer ...
You 're not paying attention!
(Yeah,it's like I do ...LOL ! )
Of course there's a dimmer !
Common for all four chips ...( of course ...)
With lower current limit threshold adjust ,also ..
My settings will be 350mA -1950mA ( ~50 to 300 Watt in total ,as 'humble' operating range .....)


The best part ...
This light is cheaper or about at the same price range ,as a good Digi ballast-reflector-hps combo.....But ....Different ...
A 'Killer' one ...As you -correctly- mentioned ...

But this built is ....
A raw power ,muscly , LED -wolverine-zombie-vampire hybrid ...

Yes a single light source ...In a single massive case ...

Specially designed to unleash sunshine to a 3x3 area ...
And beat the s..iiiit ..out of any melting Sodium 'heater' ...
That's all ...

Forget leds ,here ...
It's High intensity Diode ..
One diode ...
A big one ...
Almost 10 kgs heavy ...

That's pretty much what I'm thinking..

I like the idea of making them hid style with a lot of light density to see what these can do...makes for a easier comparison and less fixtures per area. I'd like to see these develop into 1000w equivalents that can grow a tree

Yes,that in fact is the idea,behind this type of led utilisation ...

Now ...
Sometimes fate's blows are given under the waist ....


a) Hall-sensors use electromagnetism to 'sense' electrical current changes ...
'-magnetism'....translates immediately into 'noise' in real life ....
So ...For my set (high ) standards of accurancy and ease of operation/service hall sensors ,
will never be used again with steel /ferromagnetic alloy cases /parts ...
Noise becomes the dominating 'sensing ' value ....
No way,never -again ...
Hall sensoring ,needs Tupperware or similar plastic case ,in order to show some acceptable accurancy ...

Hall -sensor kisses everybody ,good-bye...

b ) The awesome Sunon MagLev Fans ....
They just refuse to operate under PWM ...
They stand still...
Not even a buzz ..
Nothin'...

I've to research it further ,before giving up the idea of auto PWM control of the fans ..
I really like the idea of the closed loop feedback /temperature based control ...
Me ,just adjusting the light power pot ....Fans adjust by themselves ,to average Tc ...
Oh,please ...It has to be a solution there ...


c ) I'm fortelling a new arduino shield ...

CXA3070 3000°K vs GreenPower 2000°K
( Absolute radiometric Powers ,normalised to 1 )



I got you fully 'covered ' ,sister ....

wtf ^^^^^^^^^^^ for hypnosis lol

See ?
There's a simple 'light-mover' design !

'The weather 's gonna be sunny ,with a light refreshing breeze ,all day long ..."

All you need is an old ceiling fan ....

Turbulate that light,bro !

So ..
Until a solution will 'show up ' ,Arduino returns in it's
'initial' operational purpose : Tc monitor & Active thermal protection via SSR .

I've made some stupid changes to display also ....
A bar-graph ,for "quick-glance" Tc checking...

( 25°-75° C bar-graph range )

A short vid ...(used an old lcd screen ..)
I've set the Arduino to switch off the leds in case of Tc >= 75°C
Bar graph starts at 25C (far left ) to 75 C (far right ) ...
Line at the middle is 50C ...
( That's my 'general & ideal Tc operatiomal upper limit ...50 C ,no more than that ...No matter if @350mA or @1950mA ..)

I think that's the final "form" and 'operation" ..
(Till further notice,of course ...LOL...)

(Isn't cool that lcd inverts ,if any Tc goes more than 75C ? I find it cool feature... )
Enjoy..Playing around with a joint and four thermistor sensors ...

RTFM...

....but a 10 µf electrolytic cap parallel on the PWM-Output can do some magic...

great guod... you proposed Ultra Sleek Vortex 14

i see...
Corsair CO-9050009-WW Air Series AF140 Quiet Edition 140mm Low Noise High Airflow Fan Single Pack

Osram; Luxeon; Nichia
Drivers and the Arduino Micro ehhh jeje..wow

what drivers is on the photo?

i learn new word...rtfm...yeah...in spain is usual...jeje

saludos

the driver...

Where was that ?
On which manual ?
Thanx Guod ....
Anyway ...
I like the fans ,they 're keepers ...
As for controlling them ...
Well ...The 'easy' way ..
A LM2576 switching regulator ...
I've one pcb ready to operate ,already.
Tested it ,the fans liked it ...
Thing is space ..
One more pcb added ..
.
Almost same size ,with the CV PSU ,the PS-45-15 ..

If I told you that I did not had that pdf ,you would believe me ,of course ...
I know ...
