Study On The Optimal Design Of Lighting System For Comprehensive Sports Venues

In recent years,the development of sports in my country is in full swing,and the construction and transformation of stadiums are very rapid.With the development of information technology,high-definition(HD)and ultra-high-definition(4K)sports broadcasting has become the norm.The higher the requirements,however,due to the different lighting requirements of different competitions,there is often a problem of excessive lighting design in comprehensive stadiums that can hold a variety of sports competitions.The lamps and lanterns between different competitions are not shared with each other,and Relying on the designer’s experience has led to excessive use of lamps,increased initial cost,and later use,management,and maintenance costs.To this end,this article takes the comprehensive gymnasium with TV broadcast as the research object.On the basis of meeting the lighting requirements of the competition,it aims to save electricity and reduce the cost.Based on the greedy algorithm,taking handball,basketball,and volleyball as examples,this paper proposes A lighting arrangement method for a single project and a lighting adjustment method for different projects provide a new idea for the lighting design method of the stadium,and make a little effort to reduce the energy consumption of the stadium.The main research contents are as follows:(1)Select lighting indicators for the study.Expounds the related concepts and physical illumination,lighting quality influence factors are introduced,by collecting data,explores the advocate complementary camera illumination and the relationship between X and Y direction vertical illuminance,select horizontal illuminance,vertical illuminance X direction,Y direction vertical illumination and uniformity as the main indicators of lighting quality sports venues,which laid a foundation for building a database.(2)Build the illumination database.The largest handball project in the sports field is selected as the priority project.According to the "Sports Stadium Lighting Design and Testing Standard",the position of the horse track,the lighting range and the projection angle of the corresponding position of the lamp are determined,script programs and Python programs are written,and the DIALux software is used to simulate The illuminance data of the lamps at different positions and different angles form a handball illuminance database;basketball and volleyball are selected as the second and third competition events,and the basketball and volleyball courts are calculated according to the size of the basketball and volleyball courts and the relevant requirements in the Standard.The projection range of the volleyball project lamps and lanterns,the data of the opponent ball are sorted and supplemented,and the illuminance distribution database of basketball and volleyball is established to provide data support for the optimization of the greedy algorithm.(3)Propose a lighting optimal arrangement method for a single project.Using the established handball illuminance database,compile a greedy algorithm for lighting fixtures on handball courts in the MATLAB software,run the program to get the position and projection angle of the lights,build a handball court model in DIALux software according to the program running results,and compare with the greedy algorithm,Verifying the accuracy of the results of the greedy algorithm for lighting fixtures,and comparing them with the lighting cases of the same level of handball courts.The results show that the lighting layout method based on the greedy algorithm is better than the manual lighting method.It uses fewer lights,saves cost and saves Energy consumption.(4)Propose a lighting optimal adjustment methods between different projects.According to the location of the lamps in the handball event,write a greedy algorithm for lamp adjustment of the basketball court,run the program and obtain the projection angle of the lamps.According to the lighting layout of the basketball project and the requirements of the volleyball court,modify the parameters and run the program to obtain the lighting layout and projection angle of the volleyball court.According to the results of the greedy algorithm,the illuminance of basketball and volleyball courts is simulated in the DIALux software,which verifies the accuracy of the greedy algorithm for adjusting the lamps,and compares them with the lighting cases of basketball and volleyball courts of the same level.The results show that the lamp adjustment method based on the greedy algorithm is better than the manual lighting method.It uses a small number of lamps,and does not add new lamps on the basis of arranging lamps on the previous project site.By turning off the lamps and adjusting the angle,the latter can be satisfied.The lighting requirements of a project realize the maximum use of lamps,reduce the investment of lamps between different projects,and save energy consumption at the same time,which meets the requirements of the use of lamps between different projects of the comprehensive gymnasium.
