Conduction-driven cooling of LED-based automotive LED lighting systems for abating local hot spots
(SPIE, 2018-02)
Light-emitting diode (LED)-based automotive lighting systems pose unique challenges, such as dual-side packaging (front side for LEDs and back side for driver electronics circuit), size, harsh ambient, and cooling. Packaging ...
Investigation of combined optical and thermal effects on phosphor converted light-emitting diodes with liquid immersion cooling
(SPIE, 2018)
The inclusion of phosphor into a high brightness light-emitting diode (LED) package is a complicated task since LEDs are encapsulated with a phosphor and epoxy mixture to convert blue photons to white light. Moreover, this ...
Optical and thermal analysis of secondary optics in light emitting diodes' packaging: Analysis of MR16 lamp
(IOP Publishing, 2021-12-08)
Optical and thermal control are two main factors in package design process of lighting products, specifically light emitting diodes (LEDs). This research is aimed to study the role of secondary optics in opto-thermal ...
A critical review on the junction temperature measurement of light emitting diodes
(MDPI, 2022-10)
In the new age of illumination, light emitting diodes (LEDs) have been proven to be the most efficient alternative to conventional light sources. Yet, in comparison to other lighting systems, LEDs operate at low temperatures ...
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 ...
