The Research Of Light Atmosphere Perception And Lighting Design Method For The Furniture Stores

The environment atmosphere in furniture monopolized stores was studied in the paperfrom the angle of lighting factors such as lighting method, light source intensity and sourcecolor temperature. The research was divided into two parts: investigation and experimentalresearch. Based on the research conclusions, the method of lighting design in furnituremonopolized stores was put forward, that is atmosphere quantization method and it waspracticed by an example. The main conclusions were as follows:(1) By actual measurement of environment in furniture monopolized stores, it was foundthat,as respect to luminance contrast, local brightness contrast decided the level of visualsatisfaction of customers, and the higher the contrast was,more satisfaction was achieved. As tothe level of luminance, furniture with the surface of light color and high reflectivity neededlower level of luminance, while furniture with the surface of deep color and opacifier fabricsneeded higher level of luminance.With respect to luminance distribution, the luminancedistribution of integral space mainly concentrated on furniture products. The luminancedistribution of furniture product itself differed according to furniture shape.The luminance areaof high furniture mainly concentrated on vertical planes while the luminance area of middle andlow furniture mainly concentrated on horizontal planes. As to the selection of lighting method,vertical illumination, environmental lighting and accent lighting were commonly used by tradecompanies and customers were also satisfied with those lighting methods.(2)The factor analysis results of lighting and characteristics of visual perception infurniture monopolized stores showed that, the level of luminance and its distribution of integralspace and local luminance contrast in the furniture display area were the two factors of biggestcontribution rate on visual satisfaction. The total contribution rate was about50%. The secondwas ground luminance factors and the last was light color and top surface lighting. It was alsofound that vertical illumination played an important role in lighting method.(3)29subjects (15male,14female) were asked to make subjective evaluations onsimulative environment atmosphere in furniture monopolized stores.The questionnaire includedfour index:―space appearance‖,―space impressions‖,―fondness‖and―commercial ambience‖.The analysis results of―space appearance‖questionnaire showed that, whether in a singlelighting or mixed lighting conditions, subjects could distinguish different lighting sourceintensity and different lighting methods (light distribution). Stimulation had a relation with thelevel of integral space luminance and luminance distribution. Uneven luminance distributionand higher level of luminance leaded to higher stimulation. In addition, it was found that inenvironmental lighting conditions(T8), as compared to male, female felt the temperature waswarmer and light distribution was more even. The analysis results of―space impressions‖questionnaire showed that, whether in a singlelighting or mixed lighting conditions, publicity and broadness had a relation with colortemperature, intensity and lighting method. The higher color temperature, higher intensity oflight source and environmental lighting method contributed to increase broadness of the space.Low intensity of light source and accent lighting method contributed to increase the sense ofprivacy of the space.。The results of―preference‖questionnaire showed that, the preference of subjects differedaccording to different lighting types. When in a single lighting conditions, the internalconsistency of three evaluation contents on the index of―fondness‖was high. It could begenerally described that subjects preferred to lower color temperature and higher intensitylighting conditions. When in mixed lighting conditions, as to the evaluation items―beautifulfeelings‖and―attraction‖in the evaluation contents of fondness, subjects preferred the lightingconditions with uneven luminance distribution and high local luminance contrast.The results of―commercial ambience‖questionnaire showed that, the commercialambience of spaces differed according to different lighting types. When in a single lightingconditions, the internal consistency of three evaluation contents on the index of―commercialambience‖was high. It could be generally described that commercial ambience was better inlow color temperature and high intensity lighting conditions. When in mixed lighting conditions,on the premise of uneven integral luminance distribution, big local luminance contrast or highlevel of integral luminance could create―expensive‖atmosphere.―The desire to purchase‖only had a relation with integral luminance distribution and the more uneven distribution leadedto greater desire to purchase.―The sense of vividness‖only had a relation with local luminancecontrast, the bigger,the more vivid.(4) In the research on the basis of the conclusion, put forward "atmosphere quantitative"lighting design methods, will achieve specific illustrate this way, and finally with the lightingmethod of practical application.Based on the research conclusions, the lighting design method of atmosphere quantizationwas put forward, the realization ways were specifically illustrated and finally the lightingmethod was put into practice.
