摘要

提出了一种基于非视觉和视觉效应的光谱重构解决方案,以实现健康照明的理念。建立了四通道光谱重构计算模型,利用该模型根据生理节律因子、色品坐标和照度直接求解脉冲宽度调制的占空比。设计了一种可远程控制的光谱可重构的发光二极管光源,用以实验验证。讨论了生理节律因子和显色性指数的可调谐性,为相关参数的选择提供了理论指导。实验结果表明,测量值与理论值之间的相对误差较小。此外,计算模型能够指导同一色品坐标上的光谱重构,以实现生理节律因子和显色性指数的调控。因此,计算模型能良好地指导光谱重构。该研究为下一代健康照明光源的设计提供了有益参考。

Abstract

A spectral-reconfiguration solution based on nonvisual and visual effects is proposed to achieve healthy lighting. A four-channel spectrally reconfigurable calculation model that directly solves the duty cycle of pulse-width modulation according to the circadian-action factor, chromaticity coordinates, and illuminance is established. A remotely controllable and spectrally reconfigurable light-emitting-diode source is designed for experimental verification. The tunability of the circadian-action factor and color-rendering index is discussed, providing theoretical guidance for the selection of relevant parameters. Experimental results show that the relative error between the measured and theoretical values is small. Furthermore, the calculation model can guide spectral reconfiguration on the same chromaticity coordinate, achieving regulation of the circadian-action factor and color-rendering index. Therefore, the computational model can conduct spectral reconfiguration well. This study provides a useful reference for the design of healthy lighting sources for the next generation.
