With the development of economy and technology, the traditional tungsten wire light bulbs due to poor energy efficiency, in the trend of environmental protection, to be more energy-efficient LED bulbs and compact fluorescent lamps replaced. But the LED bulbs and compact fluorescent lamps issued a "cool white" light becomes brighter and slow process, a lot of people miss the days of tungsten wire light bulbs. According to reports, the US Massachusetts Institute of Technology (MIT) recently developed improved methods of tungsten wire light bulbs, the filament is surrounded with a special crystal structure, greatly reduce energy consumption which makes tungsten wire light bulbs more energy efficient than LED light bulbs and compact fluorescent lamps.
Tungsten wire light bulbs through the resistor and energized heated the finer tungsten to about 2700 ℃, allowed to issue glowing light, but in the whole process, 95% of the energy is converted to heat dissipation, so that the energy efficiency of tungsten wire light bulbs only 5%, compared to, LED bulbs and compact fluorescent lamps as the light energy can reach to 14%. It is for this reason that in 2012 prompted the EU comprehensive ban tungsten wire light bulbs.
To solve this problem, MIT scientists have developed with a special crystal structure surrounds the filament, and it will take the heat and trap the ultra-red radiation can let visible light through. The researchers believe this can make tungsten wire light bulbs energy efficiency reached 40%.
UK Energy Saving Trust data shows that if the general household use 60W traditional tungsten wire light bulbs, it takes 7.64 pounds per year (about 72.68 RMB), if using CFLs or LED bulbs, just 1.53, or 1.27 pounds per year respectively ( 14.55 or about RMB 12 RMB), but if the new improved tungsten wire light bulbs can really achieve the desired efficiency, it costs only 50 pence a year.
