Thermal characterization and lifetime prediction of LED boards for SSL lamp

Original language description

This work presents a detailed 3-D thermo-mechanical modeling of two LED board technologies to compare their performance. LED boards are considered to be used in high power 800 lumen retrofit SSL (Solid State Lighting) lamp. Thermal, mechanical and life time properties are evaluated by numerical modeling. Experimental results measured on fabricated LED board samples are compared to calculated data. Main role of LED board in SSL lamp is to transport heat from LED die to a heat sink and keep the thermal stresses in all layers as low as possible. The work focuses on improving of new LED board thermal management.
