| At present,there are many difficulties in the transformation of physical bookstores.As the core place of physical bookstores,book selling area not only bears the functional value of book selling,but also is the symbol of urban spiritual culture.In recent years,although there are fang fang,Sisyphus,zhongshuke and other "web celebrity bookstores" to create an artistic space atmosphere for the bookstore to introduce a lot of customers,the book sales area environment atmosphere mainly depends on the perspective of the designer,the lack of discussion from the perspective of consumers to discuss the comfortable book sales atmosphere in their eyes.With the development of society,habits and consumer needs are constantly changing,so it is particularly important to study the psychological needs of consumers in order to guide the material library to design the internal environment of the bookstore.Therefore,in order to understand the needs of consumers and provide them with a comfortable environment in the book selling area of a physical bookstore,this paper studies the relationship between the atmosphere and visual lightness in the book selling area of a physical bookstore and the artificial lighting and color environment in the book selling area.Firstly,this paper investigates the current situation of book selling areas in physical bookstores and summarizes the characteristics of typical physical bookstore environment.Secondly,semantic analysis is adopted to develop subjective questionnaire to investigate consumers’ demand for book selling area,and factor analysis in statistical method is used to obtain the factors that satisfy customers’ demand for book selling area.Thirdly,the quantity estimation method in the psychology experiment is used to study the subjective feeling of the color environment and lighting environment to the visual lightness and atmosphere in the book selling area.The laboratory equipment was calibrated by color reduction technology to ensure the real restoration of color display from a visual perspective.In the experiment,professional software simulation and VR virtual technology were used to enhance the authenticity of experimental conclusions through "immersive experience".Finally,the experimental results were tested by using dual comparison method.This study mainly draws the following conclusions:(1)after field research on the book selling area of 14 physical bookstores located in the commercial complex which mainly rely on artificial lighting,it is found that the main light source type used in bookstores is LED light source,and the distribution light mainly adopts general lighting,mixed lighting and key lighting.In terms of the selection of relevant color temperature,the value of the color temperature in the book selling area of the physical bookstore ranges from 3000 K to 3900 K,which is warm in terms of the features of the color table.In the investigation of color environment,the furniture in the book selling area mainly adopts Y(yellow)and YR(yellow and red)colors.The ceiling,floor and wall are mainly Y(yellow)and N(no color)colors.On the brightness of the color,the distribution is relatively dispersed without the main brightness distribution;There are no major chromaticity values in the chromaticity distribution.For the use of color in the book selling area,it is mainly 1106(8.8 yr5.5/7.6),0996(2.5 y5.5/3.2),0154(7.5 yr4.5/4),1002(1.9 y6/5.6)and gray 1276(N9),1261(N2.5)and 1714(N3.75).On the other hand,through the questionnaire survey,it is found that the atmosphere evaluation factors in the book selling area can be reduced to three factor sets: friendliness,excitement and relaxation,whose total contribution rate is close to 65%.(2)in the visual brightness experiment,two phenomena are mainly found: within the range of 100-1000 lx,illuminance stimulation and visual brightness show a logarithmic relationship,following weber’s law;At 3000 K color temperature and 4000 K color temperature,visual lightness perception is related to different color environments.At 4000 K color temperature,the growth rate of neutral color is higher than that of color environment.At 3000 K color temperature,the growth rate of color environment is higher than that of neutral color environment.(3)in the atmosphere environment experiment,there are three aspects of the findings,three emotional dimensions(excitement,friendliness and formal sense)and lighting factors and color environmental factors show a positive correlation;The evaluation of environment and atmosphere under three-color collocation is better than that under two-color collocation is better than that under monochrome collocation;Thirdly,in the two experimental scenarios mentioned in the paper,the atmosphere under the color temperature of 3000 K is better than that under the color temperature of 4000 K.(4)from the conclusion of this paper can be discussed under the book district environmental design to make the following four aspects of guidance: first,the book district in the design as far as possible to improve the visual lightness.Second,in the book selling area environment similar to the light color system and dark color system discussed in the paper,it is better to use the book selling area with 3000 K color temperature and the combination of two colors and neutral colors.Third,in the actual application,the book sales area using color environment and neutral color environment should be designed different lighting environment.In the case of similar book sales area environment discussed in the paper,when 4000 K color temperature is used,a large area of neutral color environment with high brightness value can be adopted;When using 3000 K color temperature,large area Y color system can be adopted.The 4th,when the furniture such as bookshelf booth chooses,as far as possible with the lightness value of the ground is close. |
