In this paper the improved version of the electrothermal model of LED lamps dedicated for
SPICE software is proposed. The electrothermal models of components of such lamps: the
LED module and the power supply are described. The elaborated model of the lamp makes
it possible to calculate optical and electrical quantities characterising properties of the lamp
and additionally, the internal temperatures of components of such lamps. The procedure of
model parameters estimation is worked out, too. The correctness of the elaborated model …
