Study On Light Environment Control Strategy With Multi-luminaire Collaboration

With the development of society and the improvement of lighting consciousness,people have higher demands for the office light environment than before.The traditional lighting method has been unable to meet people's individual requirements for lighting.Due to the difference of the age,visual sensitivity,work content and nature,the personnel illumination that people preferred usually has huge discrepancy.At present,high intensity of illumination has been used in most offices,ignoring the personalized lighting requirements of employees.Obviously,the staff's working status and efficiency are affected by utilizing this kind of lighting,resulting in weak enthusiasm of the staff.Researches show that people expect to gain more control of office light environment,and they also hope to adjust the intensity of illumination according to the content and nature of the work,as well as believing this kind of control is associated with health,comfort and performance indicators.Since office lighting has a lot of drawbacks,this paper puts forward a collaboration dimming lighting method for multi-luminaire Collaboration light environment,aiming to meet the personalize lighting needs of staff,combining with Internet of things and other technology to expand the scope of intelligent lighting to make public lighting to be personalized and humane.According to the individual needs of employees,generating personalized illumination rather than uniform illumination in open-plan office.It makes power consumption more scientific and reasonable to ensure employees are in good working condition,improving work efficiency and promoting creative work.The main work includes the following aspects.1)Research on the calculation method of illumination on the work face.Combining lamps light distribution curve and DIAlux optical design software,illumination of the specified point was determined by the method of theoretical study and simulation modeling.2)The theoretical research on collaboration dimmer lighting.Analyzing the feasibility of collaboration dimming from the theoretical point of view.According to the employees desired illumination and using of superposition principle to establish the mathematical model of illumination dimming coefficient.And the simple method was used to solve dimming coefficient by MATLAB software.Finally,in the actual office,the feasibility of the control strategy collaborative multi-luminaire light environment was verified by DIAlux software.3)The open-plan offices collaboration dimming lighting systems designed.In the system hardware section,introducing the composition and implementation of the system.Secondly,researching on the specific design of the system and technology.In the software part of the system,starting with the entire system,it includes software functions,analyzing the feasibility of the program,combing the program design ideas.It also gives the program flow chart and shows the effect of dimming interface software.Finally,the format and content of the information between the host computer and the next crew was introduced,and the key program functions have been described.
