Description

一种应用于光色控制的室内照明系统及方法
本申请要求了申请日为2021年2月22日，申请号为202110199466.9，发明名称为“一种应用于光色控制的室内照明系统及方法”的发明专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及照明技术领域，尤其涉及一种应用于光色控制的室内照明系统及方法。
背景技术
在应用层面，建筑设计、室内设计及照明设计均会影响室内光环境的质量。建筑设计决定了窗户的尺寸，从而控制日光照射量。室内设计决定了天花板、墙面、地面等各表面材质的颜色与反射率。照明设计负责人工光照与天然采光的整合及室内照明品质。目前基于非视觉效应的照明应用主要包括两个方向。一是将光照作为治疗手段研究光疗在诸如老年痴呆、失眠症等疾病上的临床应用。二是针对健康人群，讨论光照如何进一步提升室内环境品质，以维持人体正常的生理节律，提高工作效率并缓解情绪压力。如前所述，光照能影响人体的昼夜节律系统，光疗正是应用该理论通过适当的光刺激来调节人体的生物钟与内分泌。
人体昼夜节律主要由下丘脑的视神经交叉上核(SCN)控制，视网膜通过接受光强弱的刺激来调节SCN控制的人体节律定时系统。光刺激的缺乏或成非周期性，都将导致生物节律紊乱，产生健康问题。自然界的昼夜交替使人类已经适应24小时的生活频率，人已经适应所在地区的天然光变化，天然光的动态变化符合人体节律的需求。然而现行室内照明标准仅满足基本的视觉功效，光照强度恒定不变，无法满足人体节律的需求。室内作为人们工作、生活、学习、活动的主要场所，其照明亦需从健康角度来考虑，满足人体节律的需求。
目前通过光疗缓解季节性生理紊乱(seasonal affective disorder,SAD)已被广泛认可；清晨接收亮光刺激被证实能有效治疗阿尔茨海默病人的睡眠紊乱；适度的光照还能帮助夜班工人调节生物钟以适应夜作昼息的工作模式。然而针对光疗的研究成果有过剩倾向，有学者呼吁应该更多关注针对健康人群的优质照明，室内所接收的光照通常比室外减少40～200倍。除了桌面光照强度，许多研究开始关注近眼处光照强度，指出该指标能更好的反映作用于非视觉效应的光剂量，个别研究提出近眼处光照强度应达到1000lx才能满足非视觉效应的刺激需求。而目前大多数的室内采光均未能达到该标准，因此需要人工照明进行补偿。富含蓝光的高色温(5000～6000K)光照由于具有更高的非视觉光效，低于1000lx也可产生刺激效应。通常人们在工作与休息时对照明的需求并不相同，因此光强及光色可变的动态照明成为此类研究的主要对象。

本申请中，研究者还根据一天工作-休息模式，研究出了能满足人们非视觉效应的光照强度、色温动态变化曲线，如图2、3所示，图2给出了能满足人们非视觉效应的色温随时间的变化曲线，图3给出了能满足人们非视觉效应的光照强度随时间的变化曲线。其中，研究者还根据一天工作-休息模式制定了能满足人们非视觉效应的光照强度、色温均可变的动态照明方案：在清晨8:00开始，使用人员刚刚进入工作岗位，冷白色强光刺激模式可以让使用人员更快的适应工作环境，因此照明模式被确定为清晨冷白色强光刺激模式，清晨的光照方案从冷白色的强光刺 激开始，逐渐变为暖白色的低光照强度光照。到正午时分，约11:20～12:30之间，降至最低约500lx的光照以保证正常的视觉活动，同时低光照强度与暖色光所营造出的环境适用于休息照明，让人精神放松。午饭之后，约12:30～14:00之间，光照又重新提升至冷白的强光刺激，以激发身体活性，之后逐渐降低光照强度并转变光色至暖色。在一天工作快结束时，约17:30～18:00之间，再次给予富含蓝光的冷白光刺激，这次的刺激量较轻微，并未提升光照强度而只通过光色的改变来缓解工作一天的疲劳感。类似的动态照明根据工作日的作息规律，对工作和休息照明分别设置，提升工作效率，改善情绪从而利于人体健康。随着LED产业的发展，白光LED进入室内照明备受关注。与传统的荧光灯相比，LED拥有更为连续的光谱特性，这不仅影响着视觉感知，同时也可能带来不同的生物效应。
