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…

Excellent color quality of phosphor converted white light emitting diodes with remote phosphor geometry
The advantage in using a remote phosphor design in a WLED package is
the superior luminous flux to that of the conformal and in-cup phosphor
geometries. However, the disadvantage is its color quality which is lower than the results from the other…
