Description
When mentioning the remote phosphor structure, the most noticeable
advantage is its higher luminous flux than any other structure’s. However,
there are existing flaws in their color uniformity and color rendering index
(CRI). Thus, the improvements in these two optic factors must be improved
for the better usage of remote phosphor geometry in modern WLED devices.
Many researchers have drawn their attention to this idea, and then it has
become the primary objective for their studies. In this paper, we also try to
accomplish the same result by adjusting the distances between the phosphor
layers and through that enhance the optical properties of WLEDs. The mie-
scattering theory is applied in our calculations to ensure the reliability and
accuracy of experimental results. In our research, with distance d=0.64 mm,
the luminous flux grew 9.7% in comparison to the original value. At 0.84
mm, the distance d enhanced the color uniformity by two times. In the
meantime, the CRI remained static during the course of experiment. With
suitable application, these results can bring valuable contributions to the
development of next WELDs generation.
