Nano Engineering to build a new generation of incandescent energy efficiency higher than fluorescent lamps and LED lights

Traditional incandescent bulbs have become increasingly obsolete in recent years because of their inefficient use of energy, or by replacing power saving or environmentally friendly bulbs like LED.
If you use an incandescent lamp for a long time, you screw it down from the screw and it will be very hot. The use of tungsten lamp power and resistance principle, the fine tungsten wire is heated to about 2700 degrees, make it a hot light, but in the whole process, 95% energy is converted to thermal emission, and incandescent light bulbs energy efficiency only 5%, this is really a waste of. By comparison, the energy efficiency of LED bulbs and energy-saving lamps can reach 14%.
Massachusetts Institute of Technology (MIT) developed new ways to improve incandescent light bulbs, surrounded by filament with special crystal structure, it will take away the heat and invisible infrared radiation trapped, and let our visible light through, thereby greatly reducing energy consumption and energy efficiency in the highest end of tungsten lamp can be increased to 40%.
This victory, energy saving lamps and LED lamps at present, to know that in 2012 the EU banned incandescent light bulbs, in the world, began to focus on the legislation of lighting energy efficiency standards from 2007 countries, also affected the development of the lighting industry, manufacturers have defection to the fluorescent lamp and incandescent lamp in the LED camp, gradually out of sight. If this new type of incandescent lamp comes out, it will dramatically reduce the household electricity bill, and the 60W bulb will cost only a few dollars a year, which may be a dramatic change.
The incandescent lamp out of people's vision, which in recent years has been to "nostalgia" lighting appear, there are a few manufacturers have developed similar products of incandescent bulbs, but the use of fluorescent lamp or light emitting diode technology, to imitate the tungsten incandescent lamp and the internal structure, but are similar in appearance, internal is a superficial reform.
As shown in the spectrum, the red energy on the right side of the spectrum is the amount of heat that the visible light does not see, and MIT's approach is to return the energy to the right to shine.
Crystal filter: researchers at around the filament is provided with a composed photonic crystal structure, with excess radiation capture filament produced, and it is reflected back to the filament, for the absorption of visible light and again to send. The difficulty of the technique is to find the right material that reflects the radiation and penetrates visible light.
In fact, this kind of thought and ideas by halogen lamps, rare gas to make more heat recovery of tungsten shine again, from gas to solid, this is just a way to expand, or a recover the original simplicity thinking.
Editorial review:
Crystal filter is to let the tungsten lamp use their emitted heat again light, this is great progress of Engineering Materials Science and technology, nano technology can be heat infrared light reflecting back, only through visible light, the idea is really great! Sometimes at LED lights flicker, but it is a lot of people arch-criminal myopia, and cold in the winter looked very comfortable, miss the warm incandescent lamp, but it is the traditional power, do not know how to model the cost of incandescent lamp. I'm looking forward to the first batch of bulbs made by MIT on the supermarket shelves.
