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.
