LED lamps brightened up our lives not too long ago as a more efficient alternative to the old-school incandescent lamps. Yet it already seems they’ve got a new competitor. Researchers from the Moscow Institute of Physics and Technology (MIPT or ‘Phystech’) and Lebedev Physical Institute of the Russian Academy of Sciences came up with a prototype of cathodoluminescent lamp for general lighting. This technology has been studied since the 1980s, but without luck – until now.
The new lamp designed in Russia relies on the phenomenon of field emission and works on the same principle that powered old TVs – using cathode-ray tubes. This technology has many advantages, the authors say. It can emit light of any color (from red to ultraviolet) and withstand almost any conditions.
