| Summary: | The study covers the question of the dynamics of heat transfer in a household LED
lamp and scenarios for simplifying the modeling of thermal distribution, including
the account of heat conduction, convection and the influence of several LED light
sources. A comprehensive analysis of heat distribution processes in household LED
lamps and the development of a mathematical model of the thermal radiation of an
LED light source using the finite difference method are presented. The developed
model takes into account the lamp geometry, material properties and environmental
conditions. Special attention is paid to the influence of the location of the LEDs
in the lamp system. The novelty of the study lies in the fact that the volumetric
geometry of the lamp and light source, scenarios to account for various parameters
of the model are included in the mathematical model. Verification of the model
has shown accuracy up to 93 %. The study aims to create a more realistic and
accurate method for modeling and analyzing thermal management in multilight LED
household lighting fixtures. |
