Actually a circuit design is patentable. Furthermore it's very unethical to copy someone's intellectual property. I'm not saying don't use Samsung lm561C..... I'm saying hey design your own board. Do not make a 100% copy and then call it a Quantum Board. I'm pretty sure anyone here would not be happy if they spent the time and money designing testing and proving a specific design to have others come in with a knockoff claiming it's the same exact thing as brand X when it's already been proven at least one of those boards happened not to be the same. It can do damage to our company through misrepresentation...... Just to set the record straight we haven't paid ourselves 1¢ and still don't have our own investment money back. Yes we are growing but it sure gets frustrating to work your ass off go without sleep just to have someone straight rip you off...... We spent 1000s of dollars giving away units to prove the tech sending them off to have them lab tested and paying engineers to help us with the design...... Have these other guys done that or are they riding on what we've built?
So what you are saying is we shouldn't mind?
If so it sounds like we shouldn't invest another second or dollar into this end of the business apparently. At the end of the day if I spend the time I need to be earning money to support my family in designing testing building ECT ECT this stuff only to be ripped off, undercut with fake copies, and ridiculed for saying anything about it, I need to leave it to the rip-off artists to innovate and I'll go do something else......
Guys, do you know what is common between QB and other boards on the Samsung diodes? Nothing except the diodes themselves. The boards are even more refined, with the addition of color diodes.
To develop MPCB for LEDs is easy. Especially from the single type of diodes with the same characteristics.
There is no work to find the optimal spectrum, the development of optics and other.
The whole work takes one day, and all investments are repulsed from the first smallest lot.
In the CIS countries, people themselves make such PCBs (on osram diodes) in small batches.
561Cs are a real find for growing, but you do not need to take all the laurels to yourself. To a large extent, my claim is not to the creators of QB, but to their fanboys.
Whatever, QB is a great thing, very successful and really good.
