NUMERICAL INVESTIGATION OF HEAT TRANSPORT PROCEDURE CAUSED BY HIGH POWERED UV LED

Abstract

In many industrial applications high powered UV light has a primary importance in the production process. Unfortunately the high power UV LED modules still generate a significant amount of heat energy that has to be efficiently dissipated in order to avoid the decrease of the output power and lifetime of the LED module. To realize the appropriate thermodynamic conditions for the UV LED modules, R&D efforts are being invested into the analysis of the physical processes inside the LED modules and their environment. The scientific part of the R&D project introduced in this paper consists of the simulation of the evolution of the temperature in the high power UV LED module taking into account the environment of the module and also the active air cooling.
