Research On Light Comfort Environment Based On Fatigue,Work Efficiency And Energy Saving

In the current rapid economic development,improving the quality of indoor light environment has become a necessary part of people's pursuit of quality of life and work,for the indoor environment,in addition to the thermal comfort and sound comfort,the light comfort also affects the psychological and physiological factors of human being,such as emotional changes,fatigue degree,and so on,which determines the working efficiency to a great extent.At the same time,artificial lighting energy consumption accounted for a large proportion in the energy consumption of office building,With the increasing pursuit of high quality and comfortable lighting environment,artificial lighting energy saving has gradually become the focus of many architectural designers.In the context of this trend,create an indoor light environment which can meet the needs of indoor light comfort of building personnel,reduce the fatigue of the staff,improve their work efficiency,and research on energy saving and optimization of lighting forms are of urgent practical significance.In different light conditions(color temperature,illumination level,lighting form),based on the subjective light comfort degree,fatigue degree and work efficiency of the building staff,this paper uses the subjective questionnaire survey and experimental methods to study and analyze the light comfort environment.The main research contents and achievements are summarized as follows:(1)The subjective evaluation scores of subjects were collected through the main tourist comfort questionnaire in a variety of light environment,so as to study the influence of color temperature,illuminance and lighting form on the evaluation indexes of light comfort;(2)The subjective participate in the reading off experiments under different light environment conditions,The experimental results are quantified as the representation factors of fatigue degree and work efficiency,so as to explore the influence of different light environment conditions on human fatigue and work efficiency;(3)The critical flicker frequency measurements works under different light conditions,and The fatigue degree of human eyes under different artificial illumination conditions was analyzed;(4)Using SAS software,a comprehensive evaluation system of human fatigue,work efficiency and subjective comfort degree under different artificial lighting was established by factor analysis;According to the above experimental research results,the design scheme of light environment with artificial lighting energy saving is put forward,so as to provide a comprehensive reference for the building lighting design.
