Growmau5's BML Spydr clone: a diy led build

...on cobs without protections...

...simply on the night you can clean your les cob zones ...wait to temps down on leds before you do nothing...with isopropyl alcohol ...on datasheet comes the clean proceses...

...respect my idea...

...not lense... maybe can work on this manner too but i see more as ...a special cristal sheet for hot temps... or highly light transmissive polycarbonate material... to protect the leds from foliar feedings or other work with water or liquids...

...note... in my idea the exterior sheet.. its well separated from reflector sheet to evitate hot zones near leds ...leds needs space from exterior protection sheet ... see the hay bay lamps ...its well separated distances for my eyes...not?

...sorry for hijack a bit your thread Gromau...

...sorry PB... i dont undertand well your question... but i dont see the thin anodized aluminum sheets stamped for the reflectors acting as suplemental heatsink for add more metal... maybe works on this manner too.. but my idea its

1..the sheet acts as multi reflectors sheet...

2..but too helps on conducting or carring ...some air movement from fans to down zone surround LES cob zones or areas...remember on mi idea the sheet on the extremes envolves part of extremes hestsink... fins acts as channels of air ...the extreme of sheet for reflector capture some air and conduct the air down on all the Les cob zones or inferior areas... inside the sheet for reflectors...

...i hope you or others catch better my crazy idea... sorry my short and bad english...

Basically if I'm understanding it correctly. The aluminum sheet on the face of the panel's primary fuction is to facilitate a small amount of air movement over the cobs and reflectors themselves to keep them cool. IE to prevent plastic components from deforming or melting due to built up heat within the case.

Am I close?

So what I am getting in this the best I can understand is your talking about a lense of some sort over the cob led for protection?
That is something I have been wondering, what happens to a cob if someone gets a bit wild wild while foliar feeding or pest spraying and gets moisture droplets on a hot cob?

A few dark spots. I've accidentally blasted my solo cup rig a few times. I just powered it down and cleaned the LES with a bit of isopropyl alcohol.

near bicit near .....the primary function its acts as multireflectors sheet...

...the second function carrier the air to down zone ...cooling leds and reflectors...

the reflector sheet its separated from heatsink with separators... for facilitate the air movement..and the medium size or small size reflectors...

...catch now?...

I'm not sure how you would get it to act as much of a supplemental heatsink, but sounds like a good idea.

I wonder how efficient an anodized finish is at reflecting light compared to polished or painted aluminum? I wonder how much the thickness of the oxide layer effects reflectivity? Also the question of finish, matt or polished?

An anodized finish would have a certain 'allure' of quality compared to the other two finished(IMO).

an anodize finish is not as good a reflector as others, but keep in mind that we don't have to reflect as much light as a T5 or HID light, since most of the light is pointing down already. definitely pros and cons.

you guys have some great ideas. The panel itself was designed in this way for maximum spread ( 5ft x 5ft ), looks, and heat channeling.

This is what I had in mind when I built it. BUT, i did leave 1.25" between the fans and heatsinks so I could recess the cobs deeper into the panel and add reflectors. even if the reflectors have to stick out a bit.

I see, so the sheet isn't actually a reflector. Just covers and protects the actual reflectors. Sort of like greengenes did with his CX300.

cool concept.
but in your pic isn't most of the air following the path of the fins ? ie out the ends of the heatsink

yeah, most of it comes out of the slots at the end of the heatsink. I had the fixture face up toward the ceiling for testing. When i held a home depot receipt on top of one of the cob holes, i did see a slight lift indicating some airflow, then the receipt began to catch fire, lol. The LES is frickin hot, def burns the hair off the back of your hand.
after reading you guys comments, im thinking about going this direction. i emailled king brite to see what options they have. Looks like 63 degree is max on their website, but dont i want 90 deg?

YES, absolutely, i was really inspired when i first saw the CX300. i even thought about mitering the corners of this build, just to be a joker. but it would have been a pain in the ass and rip off of his design.

ha ha , now all you need is a focusing laser lens to burn holes.

I prefer at least 90 degrees. suggest researching reflectors at ledil.com.

I also prefer the cob to be covered, despite the loss from lenses. I'm leaning in the direction of semi-commercial lights (building units for friends.) and I want them safe and foolproof for accidental water spray.

if just for myself, no lens, no reflector, just hangem as low as I can to the canopy.

Depends on how high you want to mount your panel above the canopy. The narrower the beam angle, the further you can mount it away from the canopy. For my veggi garden for example I'm going to get ~40* reflectors so I can mount them 4-5' high so I can have room to work with stuff and harvest.

Glad I could inspire...more than you think...
Here is what I built 15 of for a client before the cx300 was around. And will probably not change much in this bigger design when it goes to PLC eventually. It's based off the original super panel if you couldn't guess.



Long sinks, single fans, recessed sinks and reflectors, 36"36 proto...32x32" final...

NOTE: Fin guards to channel the air down the sink and not up into the housing make a difference in operating temps.

thanks for sharing!

EUREKA !!!! thats exactly what i need to do for mine.

Thanks so much for sharing that. Your youtube channel was the first thing I found when i first started researching LEDs. Your work and your channel have been a huge inspiration to me. I have always liked your approach to presenting information. Keep up the great work!

@Greengenes707 I hate to admit this here, but i hacked your youtube channel using your password: bonerjamz04 and used that to steal all of your designs off of your computer. sorry bro

hahah
I really enjoy your work. Everything you do is top notch, and very detailed orientated. Much like Positivity and SDS. Two of the greatest makers of panels IMO. Your presentation of it is perfect too. Everything is there. We clearly think very much alike. If I didn't like yours designs...I couldn't like mine.

Plus you grow to validate it all. One of the most key qualities.

EDIT:
Plus...how many ways are there to design/lay it out for a square spread...basically 1. Our cooling is copying apollos in a way if someone wanted to say anything.

...not.. ...the sheet acts as multireflector principally...

...imagine one sheet aluminium preformed with this form....



....the sheet its multireflector on uper side ....down conduct the air... aliminium preformed ...i dont know her name on english... same sistem for make metal bottles for beers or refreshs... same technic to make things similars to...



...but with reflectors forms.... you can play with diferent angles and mixing diferents angles too... on design table off course... on final product the final form are fixed forever... no moving parts....

...gromau catch the idea on the ventilation side... in my idea not total volume of air from fans go on the down side ...maybe 60 % of air go out of case the other 40 % of air go on downside zone (LES zones)

...im not sure if catch totally the reflector idea too...

...i hope you or others catch the idea... .... my bad english... sorry

...sorry for my hijack or my offtopics Growmau and cia too...

...Wilson time to infusion... shout my mouth and back to chozo...

Hey how do you guys go about making your cases? Do you just do thin sheeting and use a press? Just wonderin?

how do you guys go about making your cases?

Click to expand...

The easiest way would be with a finger brake aka a metal pan brake. But one large enough for a project this big is $700-1000. So i just had the metal supply house cut the top and bottom to exact size. All other cutting was with an angle grinder, chop saw & dremel. Assembly was with pop rivets, angled alum, screw & tap, and JB weld.

does screw & tap work well to attach al angle to al sheet ?

I was thinking of nuts+bolts, but don't mind tapping for machine screws, if its neater.

gee maybe I should build a mini metal shop!
