Abstract :
The analysis of the heat flow in a light-emitting diode is carried out in the letter for the transient-state condition. In the dynamical thermal model of a light-emitting diode, the heat flow from the active region throughout the area between it and the top contact and a nonuniform distribution of a heat flux density in the active region due to the current-spreading effect are taken into account.
