Abstract

The paper presents an analysis of the influence of light-emitting diodes (hereinafter referred to as LEDs) arrangement on heat transfer to a passive aluminium heatsink of industrial LED light with an installed power of 1100 W. The structure of a passive heatsink as well as the characteristics of the heatsink material are shown. The LED light mode is displayed. The finite element method is used to analyse heat transfer and determine the maximum temperature at the observed points of the passive heatsink structure for three different arrangements of LEDs on the LED board of industrial LED light. The obtained results are analysed and the most favourable arrangement of LED diodes is determined from the aspect of even heat transfer to passive heatsink and long service life of LED industrial light.

Keywords: LED light, finite element analysis, heat transfer
