Abstract

A multi-functional nine-channel full-spectrum light emitting diode color temperature palette is proposed. The color temperature (CCT) of the palette can be continuously tuned at 1K interval within the range of 2500K—6500K. A high color rendering index (CRI) is achieved, with Ra > 94 and R1—R15 > 90. A fidelity index (Rf) greater than 91 is obtained, and the gamut index (Rg) within the range of 96 ≤ Rg ≤ 104 is achieved. Additionally, A chromaticity deviation (Duv) within the range of |Duv|
