Thermal, mechanical and multi-physics simulation and experiments in microelectronics and microsystems（2014）
摘要
Solid State Lighting (SSL) power converters are considered as the reliability bottleneck of a light emitting diode lighting system. This paper proposes a lifetime prediction method for solid state lighting power converter based on SPICE models and finite element thermal simulations. This method consists of four major parts: lifetime meter, components decay models, SPICE simulator and finite element simulator. The estimated lifetime can be obtained by a number of iterations of electronic and thermal performances of the interested power converter.
