Design And Evaluation Method Of Intelligent Lighting System Based On Behavior Mode And Functional Requirements

The lighting parameters and evaluation indicators of the existing different types of public building lighting environmental quality evaluation systems are too consistent and not targeted;which objective spaces and lighting parameters are related to the lighting environmental quality evaluation indexes,and what are the clear rules of influence between the two? Clear;the existing lighting environment quality evaluation system does not include the impact of lighting duration on the light environment quality evaluation,that is,there is no evaluation method that distinguishes the short-term and long-term adaptation process;the existing lighting control system affects the visual perception of various types of buildings The study of the efficiency function is not enough,which leads to the lighting parameters controlled by the lighting system being too single,which cannot fully meet the functional requirements of the building type.In this study,through grounded theoretical research,the main spaces,lighting parameters and subjective evaluation indicators that are generally concerned by visitors in different building types are determined through the investigation of rooted theories that affect office,hotel,and commercial buildings.Physical testing of the main spaces and lighting in the type,establishing a basic database of light environment,using a questionnaire to conduct subjective evaluation research on the subjective evaluation indicators determined in various types of buildings,and establishing a subjective evaluation information database for each type of building,based on the above results.Divide the lighting mode of each building type and study the lighting parameters and evaluation indexes under each mode;understand the research progress of the influence law between the lighting parameters and evaluation indexes of each building type lighting mode through the literature research method,and the impact of the design experiment on the unclear Conduct research on the law and conduct lighting effects experiments based on the behavior mode and functional requirements of each building type in the real architectural space restored in the variable space experiment cabin,study the influence law of space and lighting parameters on visual acuity,and lighting parameters on visual comfort degree The influence law of visual preference,attraction,and display effect;study the mapping law between visual duration and illuminance preference value through dynamic vision experiments;after parameterizing and formulating the lighting parameters,subjective evaluation indicators,and experiment laws in each lighting influence experiment,Study the efficiency functions of three types of buildings that affect visual perception.The study divided the main lighting modes of three typical public buildings and formed a basic database of light environment data;proposed mathematical formulas for the influence of space and lighting parameters on visual acuity and established SVMs for the impact of lighting parameters on visual perception in three types of buildings Two-dimensional visualization model,at the same time put forward the mathematical formula of the influence of visual time contrast preference value and establish a three-dimensional visualization model of the influence of lighting parameters and visual time on visual perception in dynamic mode;a typical public combining static and dynamic lighting evaluation is obtained A new method for building light environment design evaluation(take office,hotel,commercial building as an example);a basic mathematical model of a typical public building intelligent lighting system based on a clear visual efficiency function is established(take office,hotel,commercial building as an example).The basic data database of light environment established by the research institute can provide reliable data for the subsequent research in this field;the proposed new method of evaluation of architectural light environment design can provide a basis for the revision of the lighting industry standards,provide a reference for the lighting design of architects,The organization provides tools to evaluate the light environment quality of existing buildings;the obtained basic mathematical model can provide control algorithms for the research and development of public building intelligent lighting systems,and achieve the overall improvement of the public building light environment quality(take office,hotel,commercial building as an example).
