Utilizing CaCO3, CaF2, SiO2, and TiO2 phosphors as approaches to the improved color uniformity and lumen efficacy of WLEDs
The two elements that are most favorable in the quality evaluation for
phosphor-converted LEDs (pcLEDs) these days are the chromatic
homogeneity and the lumen output. In this study, a thorough research on
enhancing color uniformity and luminous…

The analysis of MF resin and CaCO3 diffuser-loaded encapsulations to enhance the homogeneity of correlated color temperature for phosphor-converted LEDs
The most popular method used in the production of phosphor-converted LEDs
(pc-LEDs) is dispensing phosphor freely. However, this method is inferior in
generating good angular correlated color temperature (CCT) homogeneity.
Thus, in this article, a…

Earprint recognition using deep learning technique
Earprint has interestingly been considered for recognition systems. It refers
to the shape of ear, where each person has a unique shape of earprint. It is a
strong biometric pattern and it can effectively be used for authentications. In
this…

The application of dual-layer remote phosphor geometry in achieving higher color quality of WLEDs
If remote phosphor structures are put into comparison with conformal
phosphor or in-cup phosphor, their luminous flux are better, but the color
quality is not as elevated. This leads to an obvious need of a practical
solution to enhance color…
