Research On Influence Mechanism Of Indoor Lighting Environment On Work Efficiency

The indoor environment of the building greatly affects the physical and mental health and work efficiency of the office staff.The indoor light environment supports the normal operation of the human visual system,and more than 80% information is obtained through vision.Therefore,light has a certain impact on people’s psychology and physiology through visual effects and non-visual effects,which in turn affects the work efficiency of indoor staff.Since visual effects will change with age,this paper selects the most important illuminance factor in the light environment and analyzes the age difference effect of illuminance on work efficiency.Furthermore,according to the age structure of the staff in the office,suggestions on lighting design and work space layout to improve the overall work efficiency in the office are proposed.This paper uses an experimental research method to simulate office scenes,and changes the indoor lighting environment by adjusting the illuminance of the light.The main research work and results of this paper are as follows:1.Designed a multi-age experiment for the impact of lighting environment on work efficiency,and explored the differential impact of illuminance on people of different ages;2.Put forward a comprehensive evaluation method of work efficiency based on subjective evaluation,physiological evaluation and task evaluation.Obtained various evaluation indexes according to the comprehensive evaluation table,and perform single-factor analysis of variance and Pearson correlation analysis,to analyze the difference and relevance of various indexes within and between age groups;3.A group experiment was conducted on the working population of 20-50 years old.Through the data analysis of the comprehensive indicators of subjective evaluation,physiological evaluation and task evaluation,it was concluded that the three groups of different people can effectively reach their respective best work efficiency levels under the illumination of 300 lx,500lx,750lx;4.Based on the BIM environment,a method for optimizing indoor lighting and optimizing office layout for improving work efficiency is proposed.Taking an actual office environment as an example,the indoor three-dimensional illuminance distribution under different lamps is simulated,combined with the previous research results and the actual age distribution of the office population,optimization suggestions are given for the lighting design and space layout of the office area.
