Thermal Adversity in Solid-State LightingT. Dreeben
OSRAM SYLVANIA, Beverly, MA, USA
COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is used to predict both temperatures and heat flows through numerous components of the configuration. Model output is used to evaluate different designs and construct plausible explanations for why different designs behave the way that they do.
