Research On The Comprehensive Evaluation Method Of Artificial Light Environment Quality By Space And Illumination Indexes

People's construction environment is not satisfied with the need of economic application,and more and more attention to the physical environment comfort.Light environment is one of the important physical environment,and its quality directly influences people's life.The current optical environment evaluation system is still imperfect,the current optical environment evaluation system is still imperfect,Secondly,the evaluation method adopts the form of weight grading,which still exists in the weight determination and expert evaluation.In addition,the accuracy and practicality of the widely used Kruithof comfort zone curve have been questioned.Whether the subjective feeling of the LED light environment is consistent with this curve remains to be studied.This study is based on the research and development of new technology and efficient lighting control system in the 13 th five-year plan.Study from the following chapters.In this paper,by looking at relevant literatures at home and abroad two experimental spaces of the size of the experiment were established,and the illumination color temperature was selected as the experimental parameter,and 80 experimental conditions were established through the combination of different numerical indexes,and 32 subjects were selected and three experiments were carried out using the methods of experimental research,carrying out the test of vision test,the experiment of color vision test and the subjective evaluation of comfort.Statistical analysis of the experimental data was carried out to explore the influence of the color temperature of space illumination on the color perception and comfort of artificial light environment.A regression analysis is used to obtain a formula for the influence of illumination on sharpness.By support vector machine(SVM)model in data mining comfort classification model is obtained by model visualization graphic visualization partition,intensity of illumination color temperature range is listed in the table can comfort the partition map.This study provides a reference basis for the standard setting of LED lighting evaluation,and provides a convenient and accurate evaluation method for indoor light environment comfort evaluation based on reading and writing.To subjective expression in the experimental parameters setting partition of light within the scope of environmental comfort,the result graph is to supplement and correction Kruithof comfort partition map.This study can also guide lighting design to provide boundary limit for lighting control system.
