| Due to the progress of domestic urbanization,in urban transportation,the subway bears half of the annual comprehensive passenger volume.Subway has become an important part of the life of modern urban residents.The development of subway not only brings convenience to people’s life,but also provides a unique life experience.However,although the subway facilitates people’s travel,it gives people the stereotype of crowding and noise.Therefore,improving the comfort of subway passengers has become an important topic in the design of subway passenger compartment.Based on emotional design,we should not only meet the travel needs of passengers,but also improve the ride experience.In the overall comfort design,lighting design plays an important role.According to the existing lighting design of metro vehicle passenger compartment,they mainly play the function of illumination.People seldom design lighting according to regional and personnel characteristics.However,lighting desingers should not only consider the visual comfort evaluation criteria such as "brightness" and "glare",but also obtain new ideas from the current development trend of healthy lighting design.People should be committed to "people-oriented",research and design the lighting design of subway passenger compartment.At present,the interior design of domestic subway passenger compartment has strong homogeneity,which requires designers to make targeted plans according to different regions and lines.First of all,this paper collates and refers to the representative interior scheme at home and abroad,and analyzes the components of the lighting environment of the passenger compartment.Therefore,the focus of the research is the color temperature change of the main lighting.Emotional design refers to a design concept that guides users to produce positive emotions physically and mentally.That is,based on cognitive science and previous research,this paper explores how light affects people’s preference for color temperature from visual,physiological and psychological aspects.Based on the Chengdu area,this study explores how the different seasons,morning and evening will affect the color temperature preference of passengers,and provides suggestions on the color temperature change law in the dynamic lighting design of metro passenger compartment.In this paper,the illuminance and related color temperature parameters of the actual lighting of Chengdu Metro Line 1 are measured and simulated by computer,and then the simulated color temperature parameters of the light in the software are adjusted for preference experiment.This paper concludes that commuters have different color temperature preferences and variation rules in the morning and evening of winter and summer.In each period of time,this paper determines a simulated color temperature value,and proposes to design and verify the scheme. |
