Some problems of temperature stabilization of light‐emitting diode (LED) radiation have been discussed in the paper. Temperature–electrical characteristics of LED have been discussed and a way has been suggested to use them for the improvement of techniques for the temperature stabilization of their radiation power. There exists a possibility of developing one common monolithic LED‐compensation system, and at the same time, a thermally compensated electroluminescence diode. The compensation system presented in the paper, in which an LED is a source of radiation and a temperature sensor, is not complicated and is practical in measurements where thermal conditions undergo fast changes. The presented system for the thermal stabilization can be adapted for impulse work, which allows for a considerable increase of LED radiation power. It has been proved in the paper that LED is an original source of radiation which can be applied to a construction of photometers of different kinds, working in real field conditions.
