No violations of the laws of thermodynamics are not here, the general director of "IoffeLED" Maxim Belt.
In experiments with silicon LED MIT immersion lens, produced in the "IoffeLED" when heated to a certain temperature (and it is varied in the experiment), the network 30 has consumed power PW, but gave 69 as light optical power PW. LED, as well as in theory, converted into radiation not only talk of "sockets", but also the additional heat from the crystal lattice of the semiconductor, so that the direct calculation of 'rosette' consumption efficiency was 230 percent.
Back in the 60 years of the last century, it was clear that the injection of radiation sources, such as LEDs, have great prospects as compared to incandescent light sources, that is, ordinary light, thanks to the direct conversion of electrical energy into the energy of the photon. That is why at the present time we are seeing a gradual process of replacing traditional sources of visible light to LED. In the mid-infrared (2-5 microns), that is in an area not accessible to the human eye, but important for some applications, such as those associated with the measurements of gaseous media, and the transition to LED sources. Scientists believe that the development of ideas related to the conversion of additional heat can cause the LED lights are not created in the course of the excess heat, or to new methods of cooling circuits.
