M. %J Tekhnologiya i Konstruirovanie v Elektronnoi Apparature %D 2012 %I Politehperiodika %X Powerful infrared LEDs with emission wavelength 805 ¡À 10, 870 ¡À 20 and 940 ¡À 10 nm developed at SPC OED "OPTEL" are presented in the article. The radiant intensity of beam diode is under 4 W/sr in the continuous mode and under 100 W/sr in the pulse mode. The radiation power of wide-angle LEDs reaches 1 W in continuous mode. The external quantum efficiency of emission IR diodes runs up to 30%. There also has been created infrared diode modules with a block of flat Fresnel lenses with radiant intensity under 70 W/sr. %K high-power emitting diodes %K infrared range %U http://www.tkea.com.ua/tkea/2012/1_2012/pdf/08.zip
