Annotation: There are the results of the research of emission spectra of LEDs type «КИПД 154А» in the range from room temperature to 150 С. It is shown, that reduction of luminous flux at high temperatures is connected both with the reduction of external quantum efficiency and with the reduction of luminophor covering efficiency.

Keywords: heterostructure, luminophor, quantum efficiency
