LED thermal management is important for ensuring correct lighting performance and for reliability. The Simcenter FLOEFD CAD-embedded CFD software enables lighting product design engineers to explore luminaire thermal designs early on and throughout development to avoid re-spins.
Specific capabilities in the Simcenter FLOEFD LED module include combined thermal-electrical and photometric modeling of LEDs, and the ability to import your own LED models. You can model the LED component thermal behavior in detail to predict accurate LED junction temperature when powered under a forward current and the resulting operating light output (hot lumens) for the LED installed in a luminaire.
Uniquely, Simcenter FLOEFD simulation can be combined with: measurement data for an RC-ladder compact thermal model from Simcenter Micred T3STER; and optical characterization data from Simcenter Micred LED Tester to provide the highest accuracy test data-based LED model for use in system level studies.
The LED module supports Monte Carlo radiation modeling for simulating absorption and scattering of radiation in semi-transparent solids such as glass, as well as considering the effects of refraction and specular reflection to wavelength dependency. For automotive lighting and other demanding applications, condensation modeling enables engineers to model the complexity of thin film condensation, evaporation, the influences of icing and water absorption for changes in humidity.
