I have no idea how this project product compares to crystals, sintered phosphor, etc. PDF claims it has taken 445nm laser powers up to 30W/mm2 on metal and on glass substrates. Has 96CRI at 5500K tint option. Seems like it would be handy for replacing damage phosphor layers on flip chip LED’s.
The_Driver, could you please add Lumileds Luxeon CZ to the table?
It seems to have the lowest thermal resistance of any 1 mm² LEDs that I’ve seen. Though I’m not sure if they mean real or electrical resistance, the datasheet is unclear about that. If that’s electrical - it’s still very good but no longer special.
Though then there’s a tiny thermal pad which will spoil performance for sure. If indium solder really brings actual improvements, these are going to be relatively high with this LED.
ADDED: This Luxeon C document (not CZ) makes me believe they mean electrical resistance. I’m not really surprised….still, resistance is good and I think this LED should easily get intense enough to deserve a its place in the table on the first page.
I’m not that great at Datasheets either. But it seems to have package size just a bit bigger than XP, and die size about the same as OSRAM White Flat. It is rated for 385lm from 3.0V and 1.0A current. I’d like to see djozz test it! :partying_face:
After quick look it looked like a winner.
But looking closer: it’s rated for mere 1.5A which seemed suspicious (White Flat is 3A).
Output scales nicely with current but Vf grows fast. So efficiency drops quickly.
I don’t expect it to challenge Osrams but I’d like to see it tested as well.
