Comparative Simulation Of Artificial Light Environment In Comprehensive Gymnasium Based On Lighting Energy Saving

In recent years,with the vigorous development of sports in China,the construction and renovation of stadiums are relatively rapid.Many international and domestic sports events are held every year,and the use rate of stadiums is relatively high.Most of the events require television broadcasts,so there is a high demand for the artificial light environment of the stadium.Most current stadium lighting specifications are designed to achieve high levels of lighting,with high standards for lighting standards and less energy for lighting.In addition,during the construction period of the gymnasium,the demand for post-illumination is often neglected.Due to the irregular design of the horse track,the lighting energy consumption is increased.Therefore,there is a great room for improvement in the lighting energy saving of the gymnasium.This paper focus on the stadium's architectural form and artificial light environment layout,and try to study how the stadium building affects the setting of artificial light environment by means of the investigation of the stadiums with TV broadcast system and induction and analysis of cases.Then we use the summarized lighting layout to establish an experimental model,and perform simulation analysis to summarize the quantitative relationship between different lighting layouts and light environmental quality and energy consumption under the influence of different architectural forms through DIALux.The main structure of the article is divided into the following five parts:The first part is the introduction,expounds the background,purpose and significance of the thesis,sorts out the research status of the relevant literature,and clarifies the context and framework of the article.The second part is theoretical research,which clarifies the particularity of the comprehensive gymnasium with TV broadcast,introduces the selection of the source of light and lamps of the stadium,the arrangement of lamps and the layout requirements of the bridle path,and introduces the standard values of the lighting parameters,To provide reference for later experiments.The third part includes case analysis,influencing factor analysis and model proposal.based on the stadiums with TV broadcast system,we summarize the influence of the competition project setting,the plane shape of the building and the roof shape on the artificial light environment,and present a research model.The fourth part is the experimental simulation,with the choice of lamps,the layout of the horses,the number of horses and the height of the position as the variables,using DIALux as the simulation experiment,under the premise of satisfying the lighting effect,the lighting quality indicators and the use of the lamps in the experimental results.The LPD values were analyzed and collated to study the quantitative relationship between the setting mode of the lamps and the quality of the light environment and the energy consumption under the influence of different building space forms.The fifth part is the conclusion and prospect,to summarize the research,draw theconclusion and put forward the research prospect.
