Quality Evaluating Of Residential Lighting Environment Based On Joint Investigation In China Japan And Korea

Recently the quality of residential lighting environment has been paid more and more attentions. It is realized that residential lighting environment is not only an essential guarantee for illumination but also has important impact on both mental and physical health. One of the challenges facing to researchers and designers is the quality evaluating method and standard for residential lighting environmentBased on a joint research project of investigation on residential lighting in China, Japan and Korea, this work has built an experimental environment to demonstrate the residential lighting, and set up a relevant evaluation model, then give some practical design according to typical residential requirements. The thesis is mainly including the following parts:1.Firstly it was surveyed on structure, location and lighting status in numerous residences in China based on the joint research. By comparing three countries’results, the practical status and existing problems of residential lighting in China are clarified.2.Then the affecting factors on residential lighting environment are defined by Fuzzy Delphi Method. In the work, simulated environments were set up, optics and color parameters of the selected light sources were tested, and respondents were invited to do experiments by answering pre-designed questionnaires.3.Next we adopted Weber-Fechner’s laws to analyze relationships between illumination parameters and satisfaction degree in each experimental room, finding out the effects from different illumination, color temperature, and brightness ratio on psychology. Proposal indicators about lighting environment design were put forward.4.Finally typical residential lighting environments were designed to demonstrate above research results, including living room, bedroom, and dining room.The characteristic of the thesis is proposed the design and evaluating method for residential lighting environment based on the joint research in three eastern Asian countries, which is directed by the highly integration of science, technology and art. The results are of valuable reference for green lighting practice.
