New Seoul generations coming?

I don't know if this has been published here before, but I thougt it was nice enough to give it a try overhere!
I get sometimes industrie updates in my mail and today this was in it;

Seoul Semiconductor Introduces the World's Thinnest High-Brightness Chip-LED at 0.17mm
Patent filed to strengthen company's competitive advantage

Seoul Semiconductor, one of the world's leading LED manufacturers, announced that it has launched the world's thinnest chip-LED at 0.17mm, capable of producing more than two times the brightness of existing chip-LEDs. Seoul Semiconductor has applied for a patent for its new chip.

Seoul Semiconductor's new chip-LED, WH108, measures 1.6mm in width, 0.8mm in length and 0.17mm in height, and represents a significant reduction in thickness. The WH108 is 15% thinner than the industry's exiting thin chip-LED, which measures 0.2mm. The WH108 also delivers superior performance at a luminous intensity of 240 mcd, more than two times brighter than the existing chip-LED at a current of 5 mA

I'm wondering what the junction temp will be and if it will be squared at any time (a retangle being very difficult to fit in a reflector etc).
And 240mcd is nice, but how many lumens can it push forward?
But it is hope for the future, that's for sure

Perhaps it shouldn't have been posted under flashlights, if so, please let one of the moderators move it.
Appologies ofcourse, just to hasty pushing nice news!

I wonder how much the judgement against them is going to cost them...

 

[Phaetos]

Judgement against them for what?

That's not a high-flux LED, it's a small-form factor SMT LED.

Product page. They seem to be for cellphone keypad backlights, among other things.

hmm, that is a pity! I had hope on some new led gen. but on the other hand, if they can make those twice as bright, why not "our" leds?

It's not always easy to scale things. For example, the semiconductor industry have spent billions on reducing the feature size of integrated circuits (think of the ever abused Moore's Law). In this case, they were able to achieve some benchmark numbers but it is on a form factor that is "too small" to provide useful output for flashlights. What we would like is for them to "scale it up" to a die size useful for torches and have the same efficiency numbers. That my friend is not trivial.

Should be able to make a really nice flood by using a lot of them.

Yes, but unfortunately, the masses seem to want throw I enjoy a good flood on occassion, just like I enjoy a good white wine vs. my favorite Cabs.
