Research on advancing chromatic reproduction and luminosity of a WLED using triple-layer remote phosphor arrangement
In this study, the use of triple-sheet phosphor arrangement (TRP) in
performing significant improvements to both color quality and luminous
flux of white light emitting diode (WLEDs) is introduced. The phosphor
layer of CaLaB3O7:Ce3+,Mn2+ is to…

Medium access in cloud-based for the internet of things based on mobile vehicular infrastructure
Smart cities are made up of a large number of smart, intelligent gadgets that
can sense, compute, act, and communicate. Focusing on how data is
transferred between sensory devices and applications in the internet of things
(IoT), and…

The improvement of the color rendering index using convex-dual-layer remote phosphor geometry with YOCl:Eu3+
White-light emitting diodes (WLEDs) are semiconductor light sources
whose construction design is usually made up of a single pumping chip and
a single light-conversion film of phosphor compound. The outstanding
problem of this traditional setting…

The better distant phosphor configurations for enhancing WLED color intensity: YVO4:Eu3+ and YF3:Mn2+
The distant phosphor configuration produces more illuminating beams than the
two settings containing conformal or in-cup phosphor. When this configuration
is used, though, it is difficult to manage the color standard of light-emitting
diodes…
