AI Technical Summary

Technical Problem

Existing indoor lighting technologies cannot achieve high dynamic and low glare lighting, resulting in a huge difference between indoor light patterns and illuminance and outdoor light patterns and illuminance. It is impossible to reproduce outdoor light patterns and illuminance indoors through lighting methods, and existing technologies cannot achieve natural light distribution in large or super-large spaces.

Method used

The indoor lighting control method based on the sky model controls the relative illuminance distribution of the ceiling surface to ensure that its fitting error with the target relative brightness distribution is within 5%. It uses the human eye's field of vision as the boundary for illuminance distribution mapping, divides the basic spatial units, and uses an amplification factor K to adjust the illuminance distribution in the large space to ensure the realism and stability of the light environment.

Benefits of technology

It achieves the reproduction of outdoor lighting environment visually, psychologically, and photophysiologically indoors, ensuring the continuity and naturalness of light distribution in large or super-large spaces, reducing the risk of glare, and improving the authenticity and consistency of indoor lighting environment.

Abstract

本发明提供了一种基于天空模型的室内照明控制方法，包括控制照明方式使天花面的相对照度分布与目标相对亮度分布的拟合误差在5％以内，其中，所述目标相对亮度分布为将反映天空相对亮度分布的天空模型置于室内，将人眼所处位置至天花面短边中点A处的连线与天空模型地平线形成的夹角记为β；确定天空模型上至所述D点连线与所述地平线夹角为β的点为映射照度起始点B；将B点至天空模型天顶O点的光照亮度弧线划分为N等分，按照等分节点的光照亮度分别对应的方式将天空模型的光照相对亮度分布映射至天花面然后以C点为中心旋转一周得到相对照度分布。本发明能够本发明能够确保室外光环境从人的视觉角度在室内复现的意义、真实性与稳定性，并实现大面积以及超高空间的室外光环境在室内复现。
