Thomas Edison's incandescent light bulb of the 20th Century may have been State-of-the-Art at the time, but it was far from being energy-efficient. But the more energy-efficient LEDs and fluorescent bulbs that replaced them also left a lot to be desired for many users. Tthe Massachusetts Institute of Technology (MIT) located in Cambridge, Massachusetts has been quietly working on a Next Gen incandescent light bulb with a special crystal structure in the glass that bounces back the energy at the filament where it can create new light, while still allowing the original light produced through.From release/information:
Ever since the EU restricted sales of traditional incandescent light bulbs, homeowners have complained about the shortcomings of their energy-efficient replacements.
The clinical white beam of LEDs and frustrating time-delay of 'green' lighting has left many hankering after the instant, bright warm glow of traditional filament bulbs.
But now scientists in the US believe they have come up with a solution which could see a reprieve for incandescent bulbs.
Researchers at MIT have shown that by surrounding the filament with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through.
They refer to the technique as 'recycling light' because the energy which would usually escape into the air is redirected back to the filament where it can create new light.
