Annotation: Physical and mathematical model of LEDs and LED lamps are considered. The mathematical basis is a set of differential balance equations for the thermal energy of the crystal substrate LEDs and the measuring chamber. Simulation allows us to study the thermal modes of the crystal and the substrate, to assess the effect of thermal resistance of different sections. We also consider the inverse problem when the experimental curves for average temperature of the crystal substrate and the walls of the measuring chamber are options such as thermal resistance junction-to-air crystal, the crystal-substrate, the substrate-air, as well as the assessment is made of light and heat output LEDs.
