Description
The poor color rendering index (CRI) induced by mono chip and phosphor
configuration in the conventional white-light light-emitting diode (LED)
urges for developments in both packaging and material, thus, a modern
lighting solution was introduced. The dual-layer phosphor package is an
innovative configuration that can retain the lumen output of conventional
white light emitting diode (WLED) while also enhancing color quality. The
structure of dual-layer phosphor package that was proposed includes two
chips and one phosphor. The priority in this research is to keep improving the
lighting properties of WLED, therefore, further experiments with this dual-
chips and dual-phosphor package are conducted. The lighting properties of
LED are measured multiple times with its nitride-based phosphor being
altered in proportions and densities each occasion, the results are calculated
with a color design model made specifically to monitor and adjust the color
of white-light from LED to match desired outcome. The WLED at 5600 K
correlated color temperature (CCT) is the sole research object of the
experiments. The measured parameters from the 5600 K WLED and the
color coordinates of CIE 1931 simulated from the color design model show
that 0.0063 is the highest possible discrepancy at 5600 K (CCT).
The information from this manuscript provide the manufacturers with the
most efficient approach to create a white LED that has good color quality,
high CRI and luminous flux.
