Using phosphor ZnB2O4:Mn2+ for enhancing the illuminating beam and hue standard in white light-emitting diodes
The enhancement in hue uniformity and luminous production of multiple-chip
white LED lamps (MCW-LEDs) using dual-layer remote phosphor packaging
designs are the emphases of this paper. We blended Mn2+ activated
strontium–barium silicate…

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…

Application of dual-layer phosphor geometries for enhancing the optical properties of white-light LEDs
This article compares the lumen output of two packages of two-remote
phosphor (RP). The first package is flat dual-remote phosphor (FDRPS).
The second package is concave dual-remote phosphor (CDRP). The dispersion qualities of the…

Superior hue output as well as lumen for WLEDs with dual-sheet distant layouts of phosphor
Remote phosphor constructions usually have color quality drawbacks but are more luminous in terms of lumen, surpassing conformal phosphor or in-cup layouts of phosphor. From this disadvantage, there is a great number of studies carried out to boost…

Chroma consistency and luminous efficacy for a WLED using remote phosphor configuration with a tri-layer design
The light quality of white-light-emitting diodes (WLEDs), an essential
element for the improvement of WLEDs performance, can now be estimated by the angular color uniformity (ACU). In this study, a single
micro-patterned layer is used to compare…
