Machine learning to predict junction temperature based on optical characteristics in solid-state lighting devices: A test on WLEDs
(MDPI, 2022-08)
While junction temperature control is an indispensable part of having reliable solid-state lighting, there is no direct method to measure its quantity. Among various methods, temperature-sensitive optical parameter-based ...
Pool boiling heat transfer in dielectric fluids and impact of surfaces on the repeatability
(ASME, 2022)
This study presents an experimental investigation on the nucleate boiling heat transfer (NBHT) in deionized (DI) water and HFE-7100 on bare copper surfaces. The experiments were performed under atmospheric condition at 0 ...
High brightness illumination based on laser light diffusion with mie scattering
(ASME, 2022)
Limited luminous flux per wafer area of light emitting diodes (LEDs) for high power solid state illumination causes some packaging real estate issues. This problem can be tackled with laser diodes (LDs). At high current ...
Thermal and optical performance characterization of bare and phosphor converted LEDs through package level immersion cooling
(Elsevier, 2022-06-15)
Increased demand for high flux electronics requires creative and affordable thermal management approaches to meet the performance and lifetime expectations. In the present study, optical and thermal improvements of a new ...
Rapid heating and cooling chamber for a photonics junction measurement system
(IEEE, 2020)
Since many industrial applications require heat treatment processes or validation tests under certain ambient temperatures, thermal design is a key issue to be considered in order to ensure fast heating and cooling ...
