Breakthrough LED? Or not...

[xvs]

Cyberlux put out this press release on Friday. What do you experts think: is it a real breakthrough that will give us higher output, lower power and lower cost LEDs, or is it just hype or nothing special?

Cyberlux Corporation (OTC Bulletin Board: CYBL), a developer and manufacturer of solid-state lighting solutions, announced today that the Company intends to introduce breakthrough lighting products created through the combination of the hybrid organic / inorganic white and multi-color lighting technology acquired from the University of California-Santa Barbara with the Scattered Photon ExtractionTM (SPE) technology acquired from Rensselaer Polytechnic Institute. Cyberlux will commercialize the resulting proprietary lighting technology as "Hybrid White Light" (HWL) and "Hybrid Multi-color Light" (HML). The resulting lighting technology will yield a lower cost, more energy-efficient lighting source than currently available in solid-state light-emitting diode (LED) solutions...

"and a photoluminescent polymer element positioned in the first emitted output of light, the polymer being selected to be capable of being pumped by a first portion of the first emitted output of light and when so pumped of emitting a second emitted output of light which is emitted from the device with that portion of the first emitted output remaining beyond the first portion."

sounds like some attempt at a chain reaction of sorts, a way to get the last layer of light emitting away from the die that will re-adsorb or block that same light.
kinda the same thing they have been talking about in lots of the improved efficiency, some way to get the emision to go more foreward, to DEPART from the device. like the microholes, and the reflections, and reduced phosphors, or stylised phospors for better foreward expultion.

but i aint an expert. and i cant figure out a way to roll up a press releace and get a light improvment out of anything

The part that got me was:

"Specifically, the use of the SPE methods result in a greater than 60 % improvement in light output and efficacy compared to standard commercial white LEDs."

60% is major, if true.

The questions are:
- is it true?
- what will it cost?

No one else is familiar with this here?

A name like 'Cyberlux' conjures up visions of domain squatters and spam operations rather than firms capable of serious R&D. But I digress...

All they make right now is LED lighting fixtures. There's no mention on their website of any capability to make LED dice or other low-level components. It does not seem very likely that a firm could enter the LED die market and produce a breakthrough product on their first attempt. Skepticism is in order.

THIS article, posted elsewhere in this forum has some additional detail. It appears that they cannot take as much heat as a current high-powered LED. I suspect that instead of being "more light" LEDs, they will be "lower consumption" LEDs. -Boooring!

I hope I am wrong.

I was hoping that some of the super-duper LED experts on this forum would weigh in on whether this seems like a real advance or just a pipe-dream.

NewBie? Anyone else?

if by white LED then mean 5MM..... :lolsigh:

I saw two of the cyberlux tripod-mounted light arrays at a military non lethal weapons project managers meeting two weeks ago in CA. the REEEEEELY sad thing is that it was the middle of a very bright (and cold) sunny day so I can't say how the beam looks. the devices looked odd. I thought they were little microwave antennas at first.
they claim very even 600 foot illumination.

It looks like an interesting technology, though I expect it will be best targeted towards larger area lighting. It does not sound like it would create a small source size. The 60% improvement is a maximum. 30-60% in the original release. I would be more on the lower end as anything I have read indicates the phosphor conversion is quite efficient in power LEDs.

I would have to think companies like Nichia (an expert on phosphors), Lumileds (with Philips another expert on phosphors), or Cree must be working on improvements in their technology. I wonder how much better it is than state of the art phosphor technology for LEDS or if the LED manufacturers have something up their sleeve to obtain similar results.
