Abstract

Different aspects of research, development and applications of new generation of high-brightness light-emitting diodes (LEDs) have been considered in connection with their optical and electrical characteristics, including electroluminescence spectra, power efficiency, luminous intensity angular dependence. It is emphasized that the recent breakthrough in LEDs technology is primarily based on the advances in semiconductor light-emitting structures technology allowing to fabricate superbright LEDs with luminous efficiency as high as 20 lumens/Watt that is several times higher in comparison with traditional illuminants.
