Study On Lighting Application Effect Of Tubular Daylighting System In Buildings

With the increasingly tense energy,energy conservation has become the whole society,the industry is facing a pressing matter of the moment.In building energy consumption,the energy consumption for lighting occupies a large proportion,to meet the premise of lighting,how to reduce the consumption of electricity because of lighting become the focus of attention.At this time,passive lighting is more and more show the value,but due to structural design,location and other effects,not all buildings can set the window,as a fluorescent tube to meet the needs of passive tubular daylighting system gradually Be concerned about,well known and used.In-service study period,the author participated in the work of the " Tubular daylighting system" building industry products industry standard preparation work,interest in the product and a slight understanding of the current industry on its product performance research More,the practical lighting application effect is relatively small,based on this paper presented.This article first elaborated the background of the topic,purpose and significance,In the field of tubular daylighting system lighting research status were described both at home and abroad,And in the form of a table to show the relevant papers at home and abroad on the tubular daylighting system research.And then from the basic common sense to proceed with the interpretation of the tubular daylighting system,the main contents include: tubular daylighting system terminology,the composition of the material,characteristics,requirements and lighting principle;and then understand the tubular daylighting system suitable application places and application characteristics;And gives the main points of its installation.Through comprehensive introduction,it tries to figure out the factors that may affect the application effect of light pipe tubular daylighting system lighting,which paves the way for the later research.The main body of this paper is the practical effect of the application test.In this part,the application case is introduced in detail,the selection of test samples is presented,and the test data of the application effect of each case lighting and the actual situation of the scene are analyzed.The main test method used in the stadium test is to select two longitudinal measurement lines in the artificial lighting area and three horizontal measurement lines in the tubular daylighting system lighting area,and select the measurement points uniformly on each measurement line,and each measurement point reads 3 An illumination value parameter,an average value;Underground garage test method is used to each tubular daylighting system design of the lighting area as a unit,each unit set the center measurement points and edge of the four measurement points,each measurement point to read three illumination values of the parameters,take the average.Through the above two cases of test data analysis,summed up the application of the actual lighting effects and application cases.Combined with the two cases of subjective feelings of the research situation,the true reflection of the application of the effect of the evaluation of lighting,and then the case evaluation data and evaluation criteria for analysis and comparison,and finally summarized in the full text on the basis of the author in the selection of samples and The short-board of the whole research stage,based on the results and considering the situation of short-board put forward the conclusions and recommendations.This paper uses literature reading,field investigation and theoretical analysis to summarize,analyze,compare and summarize the application effects of tubular daylighting system lighting in the present day,and discuss the factors that influence the application effect of tubular daylighting system lighting-quantity,design orientation,and artificial Lighting coordination,coordination with the surrounding landscape,product quality,post-maintenance and so on.It is hoped that the conclusion can provide some reference for the application of tubular daylighting system lighting,and provide some advice and basis for improving its application effect.
