Thermophysics and Thermal Power Engineering| Резюме: | The paper addresses the problem of determining the p–n junction temperature of semiconductor light-emitting structures, which significantly affects the photometric parameters, reliability, and lifetime of LED systems. Two approaches are proposed to eliminate the recurrent dependence between thermal power and temperature: an iterative method with step-by-step refinement and an approximation method based on a polynomial model. Both methods ensure high modeling accuracy and can be applied to optimize energy-efficient adaptive cooling systems for LEDs. |
