基于五通道的 LED 光源生物节律调控与睡眠效应研究
摘要
Abstract
To address the issue of human physiological rhythm disruption and sleep quality decline caused by LED lighting,a design scheme for LED light sources with scene-based biological rhythm regulation is proposed.Based on the spectral power distribution(SPD)of five channels including deep red,green,blue,warm white,and cold white light,combined with the CIE XYZ color space,IES TM-30 standard,and the CIES026/E:2018 physiological rhythm model,a synthetic spectrum is constructed and optimized using a genetic algorithm to achieve high color rendering during the day and low melatonin secretion at night.A control strategy of time series plus weighted smooth update is introduced to extend to dynamic and continuous spectral regulation throughout the day.The sleep quality effect is analyzed and verified through comparative verification,crossover experiments,and statistical tests with 11 healthy subjects.After the optimization of the night mode,the CCT was 2 576.7 K and the mel-DER was 0.380 0,while maintaining the Rf at 87.3.Additionally,the optimized lighting might increase the proportion of deep sleep,with limited impact on other sleep indicators.关键词
