Abstract: HP (high power) LEDs (light emitting diodes) with efficiency up to 100 lm/W and lifetime more than 50 000 hours become now the most effective light sources. Huge amount of heat generated in small volume of p-n junction, gives us the serious problems with it dissipation. In equipment with several HP LEDs (only in such devices we can achieve a sufficient amount of light) the special radiators or cooling elements have to be used. The optimization of such cooling system for assembled HP LED will be examine and describe in lecture. The proper thermal management of such electronic devices is now the basic challenge for widespread using of LEDs as light sources.

Brief Biography of the Speaker:
Konrad Domke is an Electrical Engineer. Master degree he obtained in 1974 at Kijev Technical University (former USSR now Ukraine) and PhD in “Surface load of heating coils” at Warsaw University of Technology (Poland) in 1982. In 2005 he earned DrDegree with the thesis: “Modeling simulation and examination of radiative heat transfer in the Radiance environment” at Electrical Engineering Department in Poznan University of Technology (PUT) (Poland). Presently, he is teaching at PUT and his research activities include: modeling of light and heat systems, radiative heat exchange calculations, LED cooling. From 2008 Deputy Director for Research in Institute of Electrical Engineering and Electronics in PUT charged also with the bachelor/master study. He has more than 100 publications in scientific journals and scientific conferences.
