The main light source of the future will almost surely not be a bulb. It might be a table, a wall, or even a fork.

An accidental discovery announced this week has taken LED lighting to a new level, suggesting it could soon offer a cheaper, longer-lasting alternative to the traditional light bulb. The miniature breakthrough adds to a growing trend (http://us.rd.yahoo.com/dailynews/space/sc_space/storytext/accidentalinventionpointstoendoflightbulbs/16826136/SIG=126uthfq4/*http://www.livescience.com/technology/050829_ap_lighting_health.html) that is likely to eventually make Thomas Edison's bright invention obsolete.


LEDs are already used in traffic lights, flashlights, and architectural lighting. They are flexible (http://us.rd.yahoo.com/dailynews/space/sc_space/storytext/accidentalinventionpointstoendoflightbulbs/16826136/SIG=126uthfq4/*http://www.livescience.com/technology/050829_ap_lighting_health.html) and operate less expensively than traditional lighting.


Happy accident


Michael Bowers, a graduate student at Vanderbilt University, was just trying to make really small quantum dots (http://us.rd.yahoo.com/dailynews/space/sc_space/storytext/accidentalinventionpointstoendoflightbulbs/16826136/SIG=11v388l3b/*http://www.livescience.com/technology/050415_nano_probes.html), which are crystals generally only a few nanometers big. That's less than 1/1000th the width of a human hair.

Thomas Edison is probably spinning in his grave.

I read that too...fascinating stuff. If we can overcome the challenges of financial constraints, the deployemtn of this and other great inventions will change our world.

I use to sell LEDS as a manufacturing rep and Blue Leds at first didn't exsist (1997), then so expensive. We thought it would be yrs and yrs to make them affordable. but just like everything they quickly became cheap and now created a new way to make all types of light. GOTTA LOVE SCIENCE IMAGINE YR 2015, 2030 ...
