Description

用于教室的节律照明系统及其控制方法Rhythmic lighting system for classrooms and control method thereof 技术领域Technical field
本发明涉及照明技术领域，尤其涉及一种用于教室的节律照明系统及其控制方法。The present invention relates to the field of lighting technology, and in particular to a rhythmic lighting system for classrooms and a control method thereof.
背景技术Background technique
室内光环境对人体健康有着巨大的影响。实证研究表明，光照会对人的视觉、生理功能、行为造成影响。根据研究，光照的这种影响与光敏视网膜神经节细胞(ipRGCs)有关。光信号由ipRGCs传递至昼夜节律中枢SCN，即可实现对人体生物钟与各种生理活动的调节和控制。对人体而言，当其每日得到较为适宜的时间和强度的光照刺激，可以很好地校准人体内部生物钟节律周期。若没有得到合适强度和时间的光照刺激，则会破坏这一平衡状态，进而给人体带来很大危害。研究表明，ipRGCs细胞是被其内部的光敏蛋白——视黑素所激活的。研究者根据此点建立了视黑素光谱光视效能函数来计算“视黑素光通量”，进而被改进为视黑素等效勒克斯(EML)。一般以EML作为评价标准，进行节律光谱的设计。Indoor light environment has a huge impact on human health. Empirical research shows that light can affect human vision, physiological functions, and behavior. According to research, this effect of light is related to light-sensitive retinal ganglion cells (ipRGCs). Light signals are transmitted from ipRGCs to the circadian rhythm center SCN, which can regulate and control the human body's biological clock and various physiological activities. For the human body, when it is stimulated by light at a suitable time and intensity every day, it can well calibrate the body's internal biological clock rhythm cycle. If there is no light stimulation of appropriate intensity and time, this equilibrium state will be destroyed, which will cause great harm to the human body. Research shows that ipRGCs cells are activated by their internal light-sensitive protein, melanin. Based on this point, the researchers established a melanin spectrum optical efficiency function to calculate "melanin luminous flux", which was then improved to melanin equivalent lux (EML). Generally, EML is used as the evaluation standard to design the rhythm spectrum.
基于上述研究，现有标准中也对中小学教室的照明标准进行了新的规定，如上海团体标准T/SIEATA《中小学教室照明质量分级评价》的规定，日间的视黑素等效勒克斯EML的值应大于等于200。然而，现有的照明系统对节律效应的关注较少。Based on the above research, existing standards have also made new regulations on the lighting standards of primary and secondary classrooms, such as the Shanghai Group Standard T/SIEATA "Grading Evaluation of Lighting Quality in Primary and Secondary School Classrooms", the daytime melanin equivalent lux The value of EML should be greater than or equal to 200. However, existing lighting systems pay less attention to rhythmic effects.
