Three- and four-hump nyx 22 brush InGaN-based white light-emitting diodes (LEDs) have been computationally investigated.The investigation includes three-hump LEDs precoated with green- and red-emitting quantum dots (QDs) and four-hump LEDs precoated with green-, yellow-, and red-emitting QDs.Results show scotopic/photopic (S/P) ratios $>$ 3.80 and color rendering indices (CRIs) $geq$ 70 for three-hump LEDs and S/P ratios $>$ 3.90 and CRIs $geq$ 70 for four-hump LEDs under a correlated color temperature (CCT) of 45 000 K.

Furthermore, for both three- and four-hump LEDs under the condition of CCT $>$ 5000 K, optimal results in this paper exhibit capabilities of exceeding $hbox{S/P} = 2.50$ and simultaneously satisfying the criterion of CRI $geq$ 70.Our simulation procedure is conducted under variations of nine CCTs, several wavelengths, and peak heights.Optimized airpods in jacksonville results of S/P ratios and CRIs are identified and retained through filtering off a great number of unqualified candidates.Finally, present findings may help improve the quality of eye visions pertaining to LED illumination and help reduce the electrical energy consumption related to LED usage.
