Research On Office Lighting Of Creative Design Workers

In the current information society,people’s clothing,food,housing and transportation are undergoing rapid changes,and the lighting required for daily life is also constantly iteratively upgraded.Lighting is an important factor that affects the comfort of the environment,and to a certain extent determines the psychological feelings and physiological state of people.At present,most lighting devices on the market are designed to set the lighting mode according to different scenarios such as desktop,paper,screen,etc.,and there is no research on the lighting needs of different ways of thinking of users..This article mainly studies the lighting requirements of creative designers on the lighting environment under different working methods.According to the survey on the light needs of the office environment of creative design workers,it is found that office workers have to face the computer screen(VTD)to work for a long time and sometimes need to work overtime at night.According to the analysis of the lighting methods,color temperature illuminance,and other lighting needs of office workers,the basic lighting requirements of the office lighting environment are obtained.Office lighting under the conditions of TAL lighting,working surface illuminance value of 200-500 lux,color temperature value of 3000-6000,anti-glare,color rendering not less than 80 is beneficial to increase user comfort.Among them,color temperature and illuminance are indicators that directly lead users to different psychological and physiological states.Therefore,this study takes both as the main research factors.Creative design workers,a special office group,have two modes of thinking: creative thinking divergence and thinking convergence during their work.Design psychology research shows that the mental state required under the two working states is different from the working environment.Therefore,studying the influence of the lighting environment on the working status of creative design workers under different working thinking modes has obvious innovative value.In this study,the SD psychological scale was used to test the psychological state of the subjects;Select the brain wave(EEG)time-frequency analysis method to analyze the fatigue of the subject under diffe rent lighting environments;Use AUT and mental arithmetic test questions to evaluate whether the testee’s work efficiency will be affected in the different lighting environments set by the testee.After statistical analysis of the experimental data,three lighting modes required for creative design office spaces with different color temperatures and illuminances were obtained: divergent thinking mode,general working mode,and rest mode.And based on the thinking and behavior habits of creative design workers,combined with the three office lighting demand patterns obtained from the experimental research to design the lamps.
