Looks great! Care to share the specs/inventory involved? Thanks!
Looks like:
9x QB304
9x Slate Heatsinks (#1 from the looks of it)
3x Drivers (likely Meanwell HLG240H-C1750s from the power use mentioned)
Aluminum L-angle frames
Trying to reverse engineer the QB304:
1. 8 units of SI-B8U05128HUS (22.5V tested at 240mA) connected in parallel and attached to a flat aluminum sheet?
2. At 40W per (@1.75A) board do they need a heatsink at all? Isn't it just a flat aluminum sheet?
3. Six of such boards (correct me if I'm wrong, which I probably am) can be connected in series and driven nice and soft with one HLG-240H-C1750?
4. If I use the 56cm-long version of the strips the math stays the same, just with 4 strips per board?
Wasn't there a few lines or symbols on the board missing...
Copiers got copied by another copier but the instigating copier in this case has done less overall copying so I'd say less of a copier..
Alright I'm out cap... Sorry if I intruded but not everyone is so sympathetic
Who is that we copied is my question. not here to start a fight you can take it to P.M. that's totally fine. I'm seriously curios. just an FYI Samsung LM561C has a different footprint than LM561B. We designed these boards with a lighting lab in Denver CO. If you are refering to us using a 5630 led similar to nextlight you should know that nextlight wasn't the first. Also point us to where anyone is using these leds on a
board specifically built for optics...... calling us copiers because we use a certain led that is similar to someone else is crazy...... I guess nobody better use osram ssl series at all because California Light works used that led first........ We designed that board from the ground up...... I can show cad drawings and all if need be. some competing companies will say/do anything to discredit us at all costs. It sure does suck on our end to spend as much time and effort as we have on this evolving design to get bashed like be just copied someone else.......
To get this spread in an open room took a whole lot more research and simulation/testing than we are given credit for.....
In a cab getting stuff done today but I'll give a quick reply since you quoted me.
There were very few people pushing the boundaries of led a few years ago. The new crop of led sellers forcefully took over the led forums with their spam after they saw the potential of "DIY"
People have been copying, rubbing it in peoples face, threats, doxxing, every disgusting thing you could imagine. All so they can position themselves for the led market.
In my opinion spread is over rated. I could do the same thing with 2 cobs versus a quantum board with very little difference in results.
For the copying... Everyone has a right to use any led they want. Unless you invented said led.
I avoid arguments on lighting as much as possible and I hope you don't take this as an argument
Whether you are guilty of any of these things only you know, I'm not a psychic. All I know is the things I stated as happening are very real.
So, does anybody here have experience building with these Samsung LEDs? I couldn't find on Digikey the bars mentioned by The LED Gardner, and soldering 3300 individual LEDs together in chains (aiming at 600W draw) is not something I wish upon myself. Any help, ideas, or best shared experience would be warmly thanked.
