基于多目标优化分析的图书馆阅览空间照明质量研究

The rapid development of electronic reading media is changing the traditional way of reading. Public library is an important place to read, the quality of reading room lighting is of great significance for protect the reader's vision, increasing Reading Fluency, and providing a good visual environment for readers. Thus lighting quality and energy efficiency research, which aims at different reading media characteristics, can meet the urgent needs of technology in our country architectural lighting. The project in the library reading room lighting environment as the research object, to multi-objective optimization analysis as the main technical means, according to the appropriate print and electronic media reading lighting environment design theory and method research, the establishment of electronic reading media reading comfort subjective evaluation method, determined to meet the different reading media reading comfort, lighting conditions, lighting energy consumption of objective function, constraint condition and decision variables, put forward suitable for electronic media reading features lighting quantity and quality indicators and energy efficiency lighting control strategy combining. The study result will provide the scientific principle in both designing new library lighting and old library upgrading existing one. The project results have a strong theoretical significance and application prospects for improving the quality of lighting in different reading media, enhancing the visual comfort of readers, protecting the vision of readers, and reducing the energy consumption of the library.

电子阅读媒体的快速发展正不断改变传统的阅读方式。公共图书馆是重要的阅览场所，其阅览室的照明质量对保护阅读者的视力,提高阅读效率，为阅读者提供良好的视觉环境具有重要的意义。开展针对不同阅读媒体特点的照明质量与照明节能研究是我国建筑照明中紧迫的科技需求。本项目以图书馆阅览空间的照明环境为研究对象，以多目标优化分析为主要技术手段，针对适宜纸质与电子媒体阅读的照明环境设计理论与方法开展研究，建立电子阅读媒体阅读舒适性主观评价方法，确定满足不同阅读媒体阅读舒适性、照明条件、照明能耗的目标函数，约束条件和决策变量,提出适于电子媒体阅读特点的照明数量与质量指标及与照明节能控制相结合的技术策略。项目研究成果能够为新建和改建图书馆阅览空间照明环境设计提供科学理论依据。对改善立不同阅读媒体的照明质量，提高阅读者视觉舒适性，保护阅读者视力,降低图书馆照明能耗具有很强的理论意义和应用前景。

电子阅读媒体改变了传统纸质阅读方式。以阅读舒适性为目标的图书馆阅览空间照明质量优化，对保护阅读者的视力、提高阅读效率、为阅读者提供良好的视觉环境具有重要的意义。本研究针对不同阅读媒体特点的照明质量与照明节能开展研究，是我国建筑照明中紧迫的科技需求。本项目通过广泛调研，明确了图书馆典型阅览空间的空间特征，并依此建立了用于软件模拟的空间模型与用于主观评价实验的足尺实验空间；结合主观评价实验数据分析，分别获取影响VDT阅读、纸质阅读、纸质与VDT耦合阅读舒适性的影响要素及重要性排序与舒适性阈值，得出其影响规律及优选建议；运用Dlux evo软件对典型空间进行模拟计算，提出了针对不同使用模式下阅览空间的照明能耗公式和照明节能优化策略；最后结合算法比选研究，提出了基于权重系数法的转换法做为图书馆阅览空间的多目标优化分析方法，建立了照度、相关色温、反射系数和VDT屏幕亮度4个决策变量、光源与非光源2个目标的多目标优化模型。基于多目标分析，得出最优解集，并基于此提炼出图书馆阅览空间的照明设计方法和具体优化措施。项目研究成果指导图书馆阅览空间照明环境优化设计，为不同阅读媒体使用空间照明质量的提升提供科学理论依据，同时降低图书馆照明能耗，研究具有很强的理论意义与应用前景。
