Traditional Light Bulbs May Have A NanoPhotonic Comeback

Traditional Lightbulbs Win Reprieve with New Tech Say MIT Scientists

Marie Singer | January 12, 2016



Traditional lightbulbs will win a reprieve, say MIT and Purdue scientists, who have managed to combine the warm familiar glow of the incandescent lightbulbs, that the EU and several nations want banned, with twenty-first century energy efficiency.
Incandescent lighting has remained virtually unchanged across the world since its birth about 135 years ago. Lighting inside our homes, offices and other buildings is changing rapidly, as regulations aimed at improving energy efficiency are gradually phasing out the old bulbs in favour of the more efficient CFLs (compact fluorescent lamps) and the even newer LEDs (light-emitting diode) bulbs.

A proof-of-concept device built by MIT researchers demonstrates the principle of a two-stage process to make incandescent bulbs more efficient. This device already achieves efficiency comparable to some compact fluorescent and LED bulbs.
