The Bright Future of The Incandescent Light Bulb

All We took them for dead and buried. From 2012, the traditional incandescent bulbs are banned in Europe and last year were banned in Mexico. And rightly so, only between 10% and 15% of the energy consumed by a bulb is converted to visible light. The rest is transformed into heat via infrared light.

If a week ago we strolled the majority of students at MIT have difficulties to turn on a light bulb with a cable and a battery; a research group of the University has been precisely which has revived the traditional bulb creating a prototype that equals the LEDs in terms of energy efficiency. Come on, a revolution in one of the most inefficient technologies in the history of humanity. Welcome again, incandescent light bulb?

Recycling light to make more light

The mechanism of an incandescent bulb is the same 150 years: a strand of material resistant to high temperatures (tungsten or tungsten, basically), an inert gas and a sheath of glass covering it all. The idea of the researchers has been improve the design to increase the conversion of energy into visible light. First, increased the emitting surface crushing strand to make it as flat as possible. Secondly, have created a cover for filament composed of oxides which let in the visible light but not the spectrum not visible.

Passes electric current by tungsten until it enters incandescence, all emitted radiation, materials surrounding the filament returned the infrared back to tungsten, reheating it. In this way, that energy can be ‘recycled’ using the same amount of energy to produce up to three times more than visible light. “Fundamental progress has been to design a structure Photonics that transmits visible light and reflected light”, explains Ognjen Ilic, principal investigator.

However, we are still at an early stage in terms of the real potential of this new technology. Very promising but initial. The team is working on designing structures nanoscopic improving much more even the efficiency of light bulbs. Whatever it is, it seems like in the song, the glow was not dead, I was partying.
