چکیده انگلیسی
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 was verified experimentally for the selected types of LED lamps. A good agreement between the results of calculations and measurements was obtained.
