A LED That Can Go 80yrs On One Battery?

William Henry, an applications specialist at Ireland's Tyndall National Institute, theorized that new micro LEDs can last 80 years on a single battery charge. Imagine the modding applications.

The micro LED--which is significantly smaller than conventional light-emitting diodes--requires only a few billionths of an amp to operate. Thus, it can survive for quite a while on a limited power source. One of the researchers on the project had one running constantly for two-and-a-half years on his desk. Then someone damaged it while moving it around. One member of the group calculated that it could last 80 years (assuming no accidents) on the power stored in a coin-size battery.

This would be awesome in so many applications, especially in emergency applications where it may not be used for years.
 
use these to backlight all flash mp3 players, and laptop lcds and we have a winnah!
 
Article fails to mention how MUCH light is emitted. Only states that it is visible, which likely means slightly more then nothing.
 
The micro-LED is only 15 microns across compared to a standard LED. Can't do too much modding with that.

Although they didn't mention the battery size, I still would've broken his/her thumbs.
 
The problem is finind a battery that will last for 80 years.. 20 years is really pushing it..

Great applications would be ultra-low-power requirements.. those "Shake Lights" might actually have a chance to work..

OR coupld that tech with Carbon nano-tube fabric that generates electricity, a few micro-photo eyes and you have have one hell of a way to camaflauge a soldier.. (Like Crysis.. woah..)
 
While it sounds cool, I always take announcements like this with a huge grain of salt. How many times have we heard about great new technologies under development that for some reason or another never make it to market?

The Products themselves often do not, But the technology always resurfaces later on, even 20 years later.

LED tech is a little different, rough Ideas go from prototype to market in months, even niche products..

lol
 
I wonder if someone damaged it "while moving it around", or if one of the [H]'ers in their office started wondering what would happen if you hooked up a 9v to the thing...

If we see vids of the thing exploding in the next six months you'll know I'm right...
 
The article only mentioned that it only emitted visible light. The LED might be giving off very little light, so 80 years doesn't seem as impressive as it sounds - unless they can also provide us with a battery with virtually non-existent self discharge.

What I find funny is that you've said that exactly 20 times this year and no one has noticed yet. All that salt must be getting expensive. :p

Individual products don't always make it to market, but the technologies themselves will eventually see use. Often a large company with adequate resources for mass production will buy (or copy) an idea. Regardless, we consumers end up seeing it one way or another.
 
Salt's cheap, but imagine his blood pressure if he keeps hanging out on tech forums!:p

Dont be so harsh. In this one; http://www.hardforum.com/showthread.php?p=1031995154#post1031995154
He changed cool to sincere.

:p

I think thats more than likely :p
 
They did say the battery was basically your general watch type.

I do see this entering things like Ipod/Pda size screens, probably with some sort of amplification (mirrors?)
or a few gathered together and focused (hopefully it puts out more combined that the equivalent regular LED)

Deja Vu?

Heh. You fell for it. :D

Quite the opposite--this would be useful for those applications where the light has to be on all the time, but doesn't need to be especially powerful. Here are some things I can think of that are off the grid and could make use of a reduction in power consumption:

  • Emergency floor lighting on airplanes
  • Exit lights in commercial buildings
  • Bird warning lights on towers
  • Door and ignition key guides in cars
  • Battery charge indicators in smoke detectors, digital phone modems, ... anything
 
if it were possible to build these into a "sheet" form, imagine having it backlight a laptop. The reduced power consumption increases battery life, provides even lighting to every area of the display. And hopefully doing it in sheet form would allow for "drop-in" replacements should they fail prematurely.

I was thinking more in the lines of Lifejackets, Life saving tools such as lifesavers, floatation devices, etc.

Other thoughts I had was anything that can be used in emergencies, so it's always there and will last a long time without replacements. I can see the uses being endless.
 
LED lighting is just fantastic and a real money saver. I've started changing the bulbs in my basement with bright LED light bulbs for home use.

My current project entails redoing my basement stairs, installing glass blocks in the walls and putting LED lights in the blocks. My tests look fantastic and provide great lighting for the stairs. The finishing work is the hard part as I want it to look professional but be able to have easy access if I want to change the LEDs.

I knew I had read those exact words several times before :rolleyes:.
