Design And Evaluation Research Of Lighting Environment Of Capsule Hotel Room

Capsule hotel is a kind of high-density hotel accommodation facilities.They often used in dense areas to provide people with a short break,especially to meet the lowcost curiosity demand of young travelers because of the small space,flexible location,low price and easy to add.The development prospects are promising.Capsule hotel rooms usually do not have natural lighting conditions and are highly dependent on artificial lighting.The research on the design and evaluation of the lighting environment of capsule hotel rooms aims to provide a basis for the optimization and improvement of the environmental quality of such small-scale spaces.In this paper,22 capsule hotel rooms were investigated in the field.The subjective and objective data of the lighting environment were statistically and analytically analyzed.The research results show that: the average illuminance of the bed surface to meet the standard value of 75 lx space accounted for 36%.The color rendering index higher than the standard value of 80 space accounted for 23%.Lighting indicators to meet the standard rate is low;Color temperature range of 1955-5332 K,mainly warm,intermediate color temperature;In the subjective feeling,brightness distribution,visual comfort and sense of pleasure,relaxation,spaciousness,artistic sense to achieve a satisfactory level of space accounted for 22.7%,9.1%,9%,40.9%,0% and 5%respectively,with a low overall evaluation.In order to analyze the preference law of the capsule hotel room users for lighting solutions.82 groups of lighting solutions were reproduced using DIALux evo design based on the typical space model obtained from the research.The conclusions of the subjective evaluation experiments are as follows: 1)lighting method: preference for direct lighting with better spatial brightness;2)luminaire arrangement: preference for symmetrical arrangement;3)luminaire position: when the luminaire was arranged at the junction of the interface,the top longitudinal junction line arrangement luminaire satisfaction was high;when the luminaire was arranged on the interface,the top interface horizontal arrangement luminaire and side interface vertical arrangement luminaire satisfaction was high;4)the number of lamps: preference for 3-4;5)color temperature: no significant user preference for warm or cold color temperature in direct lighting environments,user satisfaction in indirect lighting environments increases with increasing color temperature.In order to establish the evaluation model of the light environment of the capsule hotel room space,four groups of lighting solutions with high satisfaction were selected and a physical model was built to measure the illuminance(20 lx,50 lx,100 lx,150 lx,200 lx,250 lx),Color temperature(2700 K,3000 K,3500 K,4000 K,4500 K)as the independent variable.This paper carried out 96 sets of subjective evaluation experiments of lighting conditions to study the user’s preference and perception of lighting quality and lighting experience.The best working condition for the subjects’ comprehensive satisfaction evaluation was 100 lx / 2700 K;When the illuminance increased,the relaxation evaluation first increased and then decreased.When the color temperature increased,the relaxation evaluation decreased.100 lx was the best illuminance for relaxation;Sense of privacy and spaciousness negatively correlated by the level of space brightness.The darker the space,the better the sense of privacy but the worse the sense of spaciousness.By fitting the experimental data through SPSS,a spatial light environment evaluation model for capsule hotel rooms was established,which takes illuminance as the evaluation index and considers the user’s preference weighting for space and light source surface brightness,visual comfort,relaxation,privacy and spaciousness,and provides a reference for capsule hotel rooms light environment quality improvement and evaluation.This study provides a design strategy and evaluation basis for the lighting environment of capsule hotel rooms,which has certain theoretical and practical significance.
