Description

一种室内照明控制方法 技术领域
本发明涉及一种室内照明的控制方法，具体涉及一种提高视觉舒适度的室内照明控制方法。
背景技术
视觉舒适度作为评价室内照明的关键点之一，一直被照明行业所研究。目前传统室内照明技术对工作面的平均照度、照度均匀度、眩光值等传统指标较为关注，但这些指标更多只能满足视觉的基本需要，往往无法满足视觉深层次的舒适度要求。
随着人因照明相关研究的发展，被意识到的是，影响视觉舒适度的关键因素更多在于垂直/水平照度比、空间光分布梯度等新一代指标上。因此，在满足传统指标(平均照度、照度均匀度等)的基础上，进一步地控制空间垂直/水平照度比在较高水平范围，或根据特定人因考虑对空间光分布梯度进行布局，能够进一步提升视觉舒适度。
发明内容
基于现有技术中存在的上述问题，本发明提出一种室内照明控制方法，其目的在于能够使墙面形成自上而下平缓降低的亮度梯度，并实现室内照明的高垂直/水平照度比，提升视觉舒适度。
本发明的目的在于提供一种室内照明控制方法，包括：基于以天花面中心为圆心、天花面短边长度的0.75-0.85倍为直径形成的圆为界限，通过照明方式控制圆外区域总光通量占圆内区域总光通量的80％至120％，同时控制圆内区域以圆直径12.5％为间距各特征点的亮度变化程度不超过40％，及圆外区域的光照度均匀度≥0.8。
进一步的，所述天花面一般为矩形或主要轮廓为矩形。
进一步的，所述圆外区域总光通量与圆内区域总光通量可以符合关系为：
Figure PCTCN2022141902-appb-000001
Figure PCTCN2022141902-appb-000002
其中，所述φ 1为所述圆的内部区域的光通量总和；所述φ 2为所述圆的外 部与天花面边界形成的区域的光通量总和；所述ε为修正因子，

Figure PCTCN2022141902-appb-000004
其中，A为天花面长边长度；B为天花面短边长度。
进一步的，所述天花面的长边与短边的长度比
Figure PCTCN2022141902-appb-000005
为1-1.5。
进一步的，所述区域总光通量可为区域平均照度与区域总面积的乘积。
进一步的，所述圆内区域平均单位面积光通量为600lm/m 2以上，所述平均单位光通量＝圆内区域总光通量÷圆内区域总面积。
进一步的，所述圆内区域由中心到边缘以圆直径12.5％为间距的特征点亮度变化幅度为10％到15％的亮度梯度变化进行布局。
进一步的，所述圆内区域可以根据CIE一般标准天空记载的15种相对天空亮度分布模型中任意一种的天顶角0°-70°区间的亮度梯度进行平面投影布局。
进一步的，所述照明方式包括采用发光装置根据参照亮度分布将光线投射到具有漫反射特性的天花面上、采用发光天花顶棚布局天花面亮度分布、采用至少一个面光源置于天花面中布局亮度分布的至少一种。
基于大量的实验验证，在本发明的体系中，除前述限定的影响因素外，其他因素，例如圆外区域光照分布方式等，对最终的平缓度和垂直/水平照度比的影响基本处于误差范围内，因此对于本发明未提及的因素，采用本领域常规方式即可。
研究表明，视觉舒适度与垂直/水平照度比的关系大致为以0.5为中心的正态分布，其中越趋近于0.5，舒适度越高，也受墙面照度的梯度变化影响，当墙面为自上而下平缓降低的亮度梯度且平缓度越高，视觉舒适度就会越高。基于此，本发明创造性地发现，以天花面中心为圆心、天花面短边长度的0.75-0.85倍为直径形成的圆为界限，通过控制圆内区域以圆直径12.5％为间距各特征点的亮度变化程度不超过40％，控制圆外区域总光通量占圆内区域总光通量的至少80％且均匀度在0.8以上，就能实现室内中心1.5米高的垂直/水平照度比为0.4-0.6，并能同时满足墙面形成自上而下平缓降低的亮度梯度且平缓度为60％以上进而提升视觉舒适度。
本发明创造性地发现，在前述控制方法的基础上，进一步通过控制圆内区域以由中心到边缘逐渐降低且每12.5％间隔递减程度为10％到15％的梯度变化进行布局，控制圆外区域总光通量占圆内区域总光通量的至少80％且均匀度在0.8 以上，就能实现室内中心1.5米高的垂直/水平照度比为0.4-0.6，并能同时满足墙面形成自上而下平缓降低的亮度梯度且平缓度为70％以上进而进一步地提升视觉舒适度。
本发明创造性地发现，在前述控制方法的基础上，进一步通过控制圆内区域根据CIE一般标准天空记载的15种相对天空亮度分布模型中任意一种的天顶角0°-70°区间的亮度梯度进行布局，控制圆外区域总光通量与圆内区域总光通量符合关系为：
Figure PCTCN2022141902-appb-000006
且均匀度在0.8以上，就能实现室内中心1.5米高的垂直/水平照度比为0.4-0.6，并能同时满足墙面形成自上而下平缓降低的亮度梯度且平缓度为80％以上进而使视觉舒适度达到更为理想的状态。
相对于现有技术本发明具有如下效果：
本发明通过控制天花面的光照亮度分布，能够使室内中心1.5米高的垂直/水平照度比为0.4-0.6，更进一步地甚至能达到0.55-0.57的水平，同时使墙面形成自上而下平缓降低的亮度梯度且平缓度为60％以上，更进一步地甚至能达到80％以上，从而更好地提升视觉舒适度。
