Abstract
The study includes an overview of indirect temperature measurement methods of the Light-Emitting Diode (LED) chip. It is considered the measurement method of thermal performance of the LED chip, based on dependence of the electrical parameters on the temperature. It is described the automated experimental unit for measuring the chip temperature of the working LEDs. There are described the results of measurements of the chip heating and cooling dynamics at various currents. It is carried out the analysis of thermal processes occurring in the chip upon its heating by the flowing current. It is shown that the most simple and fairly accurate temperature measurement method of the chip is the method of direct voltages.
