The incandescent bulb itself can absorb heat light, more energy-efficient
Compared to traditional bulbs, the advantages of LED bulb is self-evident. Almost certain, LED bulbs next will appear in our lives every corner. LED bulbs biggest advantage is energy saving, but it is also very obvious shortcomings, it is not "warm." Are you sure you want to reduce the energy-saving light bulb itself, the heat it? The answer is definitely not the case. Recently, the Massachusetts Institute of Technology research team proposed a new solution.
MIT researchers have developed a new incandescent bulbs, the bulb can absorb heat from their own, then those calories then converted into electrical energy to power lights. After this cycle, the new LED bulbs than incandescent bulbs more energy efficient.
In fact, this new type of incandescent bulb does not change the principles of traditional incandescent bulbs, the light bulb is only attached to the surface layer of the crystal filter. The role of this filter is: After the light is emitted, then you can at the same time reflecting infrared waves to the filament, filament reabsorbed emitting light into electricity again. So it goes, ad infinitum, until the lights turned off.
But hear this, loyal fans of incandescent bulbs we should not be too excited. This new incandescent bulbs currently exist only in theory, that possibility is not listed in the short term. But R & D team, said that for this theory into practice, they still very confident.
