Abstract

For Solid State Lighting devices thermal management has a great impact on the performance. Therefore, it is necessary to analyze thermal and optical behavior simultaneously due to the mutual interaction between the two. For a remote phosphor configuration the dependence of the device performance on thermal conductivity and refractive indices of phosphor’s host material is investigated. Even though the temperature range inside the phosphor can be dramatically reduced by choosing the right material, the overall performance suffers from the low extraction efficiency of light due to the high refractive index of the chosen material.
