Help With DIY CREE CXB 3070 Project

Hey Rollitup Comminuty! need your help with a DIY project I have in mind and want to manifest. Keep in mind I am a novice DIYer and I am just getting into this whole thing...please use simple terms or try to describe what you are referring to when answering..thanks. I'd also appreciate it if someone could point me in the direction of some thread or webpage which is something like "DIY LED's for DUMMIES" lol..I really want to learn this stuff...I've read countless threads but don't get the drift yet...like wiring in series and what not.

I've been given pointers to stop using red/blue XPE chips which I was previously using and to switch to the high powered COB type CXB 3070 chips.

I want to build a DIY LED panel which utilizes anywhere between 200-250watts actual watts. I think the CXB3070 chips at AD bin are 50watts each...correct me if I am wrong. So, what kind of driver would I need to power 4 of these chips to make a 200w unit? I want to stick with Meanwell brand.

I would appreciate it if you guys look over my shopping list and please let me know if all the parts are compatible together ...or if I can make improvements in any area..

Here are the items on my shopping cart so far:

CXB3070 AD 3000k Chip: http://www.digikey.ca/product-detail/en/CXB3070-0000-000N0HAD30G/CXB3070-0000-000N0HAD30G-ND/5302243

Heatsink/Fan:http://www.newegg.ca/Product/Product.aspx?Item=N82E16835186070&cm_re=alpine_11-_-35-186-070-_-Product

Driver: Still debating (need help here) how about Meanwell HLG-185H-C1400B to power x4 of the above mentioned chip?

External HDD powersuply for fans (not sure if this is necessary...saw on another thread someone was using it) - http://www.frys.com/product/7613847?site=sr:SEARCH:MAIN_RSLT_PG


I'd also like to build a frame such as the one shown in this thread: https://www.rollitup.org/t/4-cxb3070-meanwell-hlg-185h-c1400b-driver-want-to-order-tonight-need-input.862784/page-3

I wanted to know if it is necessary to use anodized aluminum for the frame or is that just a preference? can I use something like these materials for the angles: ..it is called "CRL Chrome Plastic 3/4" Reflective Inside Angle".

Hoping I can find some answers here on Rollitup since I've seen and learned from so many DIY threads and was pointed in this direction here..

Any advice would be greatly appreciated! Thanks Rollitup members for the great knowledge!

Bump?

Digikey $58/cob is crazy for 3070. That too AD bin 152 lumen/watt at 1.4amps
You can also get CXB3070 for $35.5usd from Jerry
Many people here get cxb from him and it is a lot cheaper. Jerry will give you BB bin which is 160 lumen/watt at 1.4amps

3070 BB is 49.83 watts per cob at 1.4Amps
Checkout spreadsheet here

Meanwell HLG-185H-C1400B will power 4x 3070
Good and efficient single driver option. with B option you will need to connect 100K linear taper potentiometer for dimming 10-100%. Some detail here
If you want single driver per cob the more $$

Anodized aluminum not important for frame unless you want attractive colors.
We use anodized aluminum on heatsink for better passive cooling performance for heatsink. Frame anodized dont mater.

I don't know if Artic 11 uses 4pin or 3 pin
You can buy a fan hub like this if you don't want to cut Artic 11 fan wires

search on ebay for more options 'Fan Hub'
I got this idea from here

Most DIY here are just cobs as they are very efficient and easy DIY. Some DIY with 3000k cob and blue LED's and some with 4000K and Red LED's
Info about 730nm XPE here and here

Thank you for your reply! very helpful information! This clears a lot of things out. =)
I did some reading following your links and am now looking into the CXB3590's...what would be the top bin for those in 3000k? and would they be mountable on the alpine 11 plus fans? I want to make a 4-COB only panel...no blues no far reds...

Also, by "Jerry" do you mean Kingbrite? I heard of them and will go with them if I can save $$.

Thanks again for your great help! Much appreciated.

Yes Jerry is kingbright guy
His email ID is jl@kingbrite.cn and he can take paypal payment and email you invoice

I think $46.50 for each cxb3590


3590 top bin is CD in 3500K spectrum
Same driver will work fine with 36V option
same as last page. Checkout spreadsheet here

Greengene said 3590 will work on Alpine Arctics 11 here

Ideal 50-2303CR holder for 3590 COB. Jerry sells this too.
Use http://www.findchips.com/ to find components USA suppliers

Reflector option:
F13838_ANGELINA-XW can be attached with this Ideal 50-2300AN

Looking forward to seeing your build. Good luck

Thank you so much!! I will go ahead and send my order request to Jerry. I hope to be able to find good parts to build a frame..I have gotten good ideas from some threads.

By the way, does anyone have experience working with chrome coated plastic? Would I need a drill press at all to mount the chips and holders/lens onto the heatsink and then to make holes for screws to mount the heatsinks to the frame? or will a simple handheld dremel do the job? Forgive me for my ignorance...I am starting from scratch and lack knowledge in this area..though I am pretty good with my hands and have wired magnetic HPS ballasts in the past.

Thanks again for your continued support and help everyone! =)

One thing I just noticed about the CXB3590 is that it has a maximum power of 137 Watts...would two of these be suitable to run with a single Meanwell HLG-185-C1400A driver? or would I have to dim? On second thought, I think I'll go with CXB3070s with AD bin...what do you guys suggest?

I say run B3590s if you want to kick ass, more efficient, and that driver should be great for two 3590s. (Right, LED gurus?)

Check this out, he's running four 3590s per driver, I believe its the exact same model. Good stuff. Looking forward to seeing your build.

I am leaning toward this decision. The +6% efficiency is a big enough number. Thank you for the confirmation about the driver. Will go ahead and process my order with confidence now.

I will document my build...I still need info about building but will look at the parts and see if common sense is enough.
Thanks to all the members for the generous sharing of knowledge! Couldn't stress that enough.
