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…

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…
