Current white LEDs are in principle blue LEDs embedded in phosphorus which then absorbs the blue light and re-emits it at large range of wavelengths, in effect giving blue light.

I would say, that the biggest motivation for this research project is providing salaries to those who do it. A little disclaimer here: I am a researcher myself.]]>Feb 13th 2010 9:11AMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/
Are these new lights dimmable is what I want to know. I use CFLs, but there are some rooms where dimmers are a requirement in my opinion. Particularly bedrooms and dining areas. The LED lights that are starting to show up the hardware store are also not dimmable. Such a disappointment. ]]>Feb 12th 2010 2:06PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/
yeah, I was wondering how efficient these were compared to LED lighting, which are completely undimmable, so if the nanofiber is dimmable, that would easily make it more marketable than a LED light.]]>Feb 12th 2010 2:10PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/The problem isn't that the mercury will leak out and harm you directly, it's that too many people can't be bothered to recycle these CFL's and the mercury ends up in the landfill. One bulb isn't that big a deal, but millions are. Mercury is a nasty toxin that finds its' way into our food all too easily. Getting rid of it in products that get thrown into landfills can't happen too soon, for all of our sakes.]]>Feb 12th 2010 2:34PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/
Dimmable LEDs are available.

Yeah, but how much do they cost? Dimmable CFLs are available too, but they all suck because they don't dim enough.]]>Feb 12th 2010 3:22PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 2:11PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 2:16PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/
I don't know if it needs nanofibres, but LED lighting should be a step forward especially for areas where CFL isn't really well-suited (if you turn lights on and off very frequently, for instance, or if you need a small/odd form factor). I expect in a few years it will be cheap enough to use at least in those areas; maybe eventually it will take over from CFLs.

By the way I kind of think one of the limitations of lighting is nothing to do with the lighting technology but only with the control technology. Making an LED light that can dim is trivially easy - making one that can dim itself based on the variations of the up-to-220V mains supply is a bit random. Similarly, LED lights should probably be able to colour-shift with remarkably little effort, but you probably don't have a lightswitch with colour options. Probably LED lights will really come into their own if we get to a point where an alternative infrastructure can be considered, i.e. it doesn't have to work with your existing wiring and switches.]]>Feb 12th 2010 7:11PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 2:52PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 2:59PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 10:19PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 3:02PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/]]>Feb 12th 2010 3:06PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 3:46PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Why not just use a white LED and thats it? White LEDs are blue LEDs with a glob of yellow phosphorus material on them. Same stuff they sprayed on the nano fiber. Looks like these guys took a step back...

All LEDs are dimmable. You blink them really fast with a varying duty cycle. Jargon: PWM.

In most phones you can change the brightness of the screen. Put yours on the lowest setting, sit in the dark and wave the phone back and forth in front of your face. You should be able to notice the blinking. Works better with light text on a dark background.]]>Feb 12th 2010 4:15PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/Feb 12th 2010 4:19PMhttp://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/http://www.engadget.com/2010/02/12/nanofiber-lighting-promises-to-be-better-safer-than-incandescen/
Of course! Because as we know, the ONLY reason for being more efficient is for if you believe in global warming... definitely has nothing to do with saving money, wasting less, and... saving a lot of money.
