New LED technology increases light output

Very interesting article at:
http://www.utah.edu/unews/012201_light.html

Highlights:

New organic plastic LED's with spin "randomizers" will increase efficiency from the 10 percent of current LED's to about 41-63 percent.

This equates to more light output, longer battery life, smaller packages.

LED's are headed for the big time (of course we all knew this).

Hope these new high efficiency leds become commercially available soon. The only down side is that all our existing flashlights will practically be obsolete.

Yes, just like the first transistor radios when they started replacing tube types. The original LED lights will be remembered as the first of a new revolution.

I can imagine what people must have first thought thought about transistors. "So what, its smaller, uses less power and never burns out. But I don't have to replace tubes in my radio enough to justify the extra cost of a transistor radio."

And then they got less expensive than tube devices. And the transistors unique qualities opened up new applications that the tube people could never imagine- like portable MP3 players.

Where as a tube wasted most of its power in heating the filament, the transistor delivered all it's "power consumption" to the task at hand. Also, instead of making each device so that the tubes could be replaced, transistors were permanently mounted in devices.

Yes, we are an odd bunch, us transistor/LED freaks. But I think we are on to something...

Unfortunately I get "page cannot be displayed" when I try the link. Is this similar to the pulsing concept?

Ken, I just checked the link, and it loaded fine. Maybe try another browser?

To answer your question about pulsing, no this is something different.

The efficiency is being increased by "randomizing" the spin of the electrons and "holes", thereby improving the chances of a combination.

If this were used in conjunction with Agilent's irregular dice technology, efficiencies of over 70 percent are conceivable.

I estimate that it will take the randomization technology a year or two to make it through all the paperwork before it starts showing up in devices.

Does this mean I can trade in my HDS headlamp for that McIntosh tube stereo amplifier I always wanted as a kid?
