Mathematical simulation of heat transfer processes at the maximum possible electrical loads in typical light-emitting diodes

Abstract

Abstract. The physical and mathematical models for prognostic research of possible thermal operating modes of typical light-emitting diodes (LED) at critical electrical loads have been developed. The highest currents have been set, at which LED's compound melting begins. LED's characteristic times at these electrical loads have been identified. The influences of compound's material properties (density, thermal conductivity, heat capacity) on LED's operating characteristics have been determinate at critical currents loads.
