It's because none of them are lighting manufacturers, they are all luminaire manufacturers. All they care about is stock shifting or using existing lighting modules in custom enclosures.
Thanks, I am probably predictable in asking, ..then why don’t they bother to employ a lighting power supply designer?, then they could have the perfect custom solution for each luminaire, and have it in house, instead of having to buy it in from an external source.
I don't think so. My Osram luminaires don't have Osram drivers. My Philips luminaires don't have Philips drivers.
Thanks, but then I wonder how Osram and Philips survives?
Basically we seem to be saying here that all these companies use (probably) Chinese LED drivers(?)
So how much cheaper is it to get the LED driver designed in China? Half the price of getting a UK power supply designer to do it in UK?…….a tenth of the cost?...a twentieth of the cost?
Is the cost going up or down as time goes on?
Why do British local authorities often insist on buying lamps from “British” companies who do design and manufacture “in house”?......i mean , surely they should get with the times and just tolerate the fact that bringing it in from China is the way it works now?…….
Then the horrible realisation that even a “British designer and manufacturer” might actually be just full of “stooge” engineers, who are pretending to design stuff, when secretly its all being brought in by the back door from China.
There seems to be this inescapable truth that buying LED drivers in from China is THE way forward….yet there is this horrible realisation that doing it like this ultimately leads to disaster, where we end up with a country where no one knows how to evaluate any LED driver design, and ultimately we will end up getting ripped off by the Chinese when buying their led drivers, because when we totally loose our capability to design them, the Chinese will ratchet up the price and really make us pay…..but then, if this were a known fact, then why are the UK politicians doing nothing about this?
Ditto all this in all other countries.
