A luminous efficacy model for a white light‐emitting diode (LED) cluster was developed, and five α‐opic efficacy ratios (γ_α,Vs) of intrinsically photosensitive retinal ganglion cells were adopted in order to quantify its nonvisual performance relative to natural light. A tunable C/A/R LED cluster, which consists of the cyan LEDs with green phosphor excited by a blue LED, the amber LEDs with green and orange phosphors excited by same blue chip, and the red LEDs, was proposed by maximizing the average luminous efficacy at correlated color temperatures (CCTs) of 2700 to 6500 K under the condition of color fidelity index (R_f) above 96 and five values of γ_α,V of 0.95 to 1.05. The real tunable C/A/R LED cluster with a R_f of 95 to 96, five values of γ_α,V of 0.97 to 1.01, and a luminous efficacy of 114 to 120 lm/W at a CCT of 2670 to 6456 K were demonstrated. Furthermore, five values of γ_α,V can be adjusted according to the distance from the Planckian or daylight locus on the CIE 1960 uv chromaticity diagram at different CCTs. Thus, the tunability of γ_α,V value of the C/A/R LED cluster at a specific CCT could be applied to different requirements for nonvisual performance.

高效且可调的白色发光二极管集群，具有逼真的色彩和逼真的自然视觉效果

用于白色发光二极管（LED）簇A的发光效率模型的开发，和五个α-OPIC功效比（γ _α，V S）自主感光视网膜神经节细胞被以它的非可视相对于自然的表现量化通过光。通过最大化平均值，提出了一个可调谐的C / A / R LED集群，该集群由蓝绿色LED激发的绿色荧光粉的青色LED，蓝绿色LED激发的绿色和橙色荧光粉的琥珀色LED和红色LED组成。发光效率在2700色彩保真度指数（的条件下的相关色温（横向专题）至6500ķ ř _˚F）以上的96个五个值γ _α，V为0.95〜1.05。真正的可调C / A / R LED集群ř _˚F的95至96，的五个值γ _α，V 0.97〜1.01，和114至120流明/ W中的至6456 K含量证明2670的CCT的光效。此外，五个值γ _α，V可以根据从普朗克或在不同的CCT在CIE1960uv色度图上的距离日光轨迹调整。因此，可调性γ _α，V在特定CCT的C / A / R LED簇的值可以被应用到用于非可视性能不同的要求。
