Analysis and Prospect of the Development Status of Stadium Lighting

Through the actual measurement and investigation of a large number of stadium lighting, a large amount of data including lighting level, lighting quality, lighting design and lighting power consumption has been obtained. Statistical analysis of these data is available for the revised "Sports Hall Lighting Design and Testing Standards". The reference of value is of great significance for guiding the lighting design and energy saving of stadiums.

1 Introduction

Since the successful hosting of the 29th Summer Olympic Games in 2008, China has successfully bid for the 2022 Winter Olympics. China is moving from a sports power to a sports power. According to the national "Several Opinions on Accelerating the Development of Sports Industry to Promote Sports Consumption" and the spirit of "Developing National Fitness, Competitive Sports and Sports Industry" proposed by the two government work reports, the sports industry will become an important force to promote sustained economic growth.

By the end of 2013, there were more than 1.69 million sports venues and more than 6,000 large-scale sports venues in the country [1]. In the next few years, the number of sports venues in China will continue to increase, indicating that the construction of sports stadiums in China is still at a high-speed development stage. For the stadiums to be built in the future, the planning should be more scientific, the design should be more reasonable, and the functions must first meet the requirements of sports and sports events. In particular, China has initially formed a sports professional competition system, and has taken on more and more Many international major events have more stringent requirements for sports venues.

The functional requirements of sports lighting are very high, especially in sports venues with TV broadcasts, which have higher functional requirements for lighting. High illumination, high uniformity, high light source color rendering in stadiums, etc. require good lighting. In addition to the product, reasonable horse setting and high level of lighting design, there is also a high power consumption.

A large number of actual surveys have shown that because the position of the horseway, that is, the installation height of the lamp is not reasonable, it not only directly affects various lighting technical indicators, but also causes a large amount of waste of electrical energy. This paper will analyze the technical indicators of lighting design and the main factors affecting the lighting power density through the actual survey of a large number of stadiums, in order to provide reference for lighting designers in the design of stadium lighting. At the same time, it is a hot issue in the current lighting applications - whether LED can be used for sports lighting for further discussion.

2. Survey of stadium lighting survey

The Construction Quality Inspection Center of China Academy of Building Research has conducted lighting inspections on hundreds of stadiums across the country for many years, and has undertaken lighting inspection, commissioning and acceptance of all venues of the Olympic Games, Asian Games, Universiade and National Games. A large number of lighting engineering on-site inspection data. In the revision process of "Sports Lighting Design and Testing Standards", the member groups and lighting companies of the compilation team have designed a large number of important sports venues at home and abroad, occupying a very important position in lighting design, and have rich design experience. Provides a lot of valuable data. Analysis and summarization of this valuable information laid the foundation for our completion of the revision of the standard.

2.1 Overview of the survey of stadiums

The collected data includes more than 300 venues for the actual measurement and statistics of important sports venues in the country, all of which are competition venues, including a large number of high-level competition venues (V or VI), and domestic and foreign sources provided by various lighting design units. The lighting design data of major sports venues has collected more than 1,000 venues, including outdoor stadiums, comprehensive gymnasiums, tennis halls, swimming pools, competition venues and training venues. In more than 1000 cases of data, due to incomplete project content, or the test data can not meet the standard requirements, this part of the venue has been removed from the statistics, the number of stadiums that can participate in statistical analysis is more than 900, including 462 competition venues and training. There are about 440 venues. The survey contents include lighting methods, fixture installation height, lighting power, illumination, illumination uniformity, illumination ratio, color rendering index, color temperature, glare, and so on.

2.2 Number and functional level of the venue

In the competition venues of the survey, there are many outdoor stadiums and comprehensive gymnasiums. The number of venues with functional level V is slightly higher than Grade IV and VI, as shown in Table 1.

2.3 luminaire installation height and functional level

According to the statistics of the installation height of the luminaire, the following conclusions can be drawn:

(1) The number of stadium lighting installations between 40m ≤ h < 50m accounts for 45.7% of the total height, which means that almost half of the existing stadium lighting installations are between 40m and 50m; The installation height of the tennis hall and swimming pool lamps is between 15m≤h<25m, which accounts for more than 60% of the total height. That is to say, the installation height of the stadium's lamps is generally between 15m and 25m.

(2) In general, when the height of the lamps is low, the probability of occurrence of low-level (IV) competition venues is too large; when the height of the lamps is too high, the probability of occurrence of high-level (VI) competition venues is too large, because high-level refers to Major events, high-definition television broadcasts, stadiums accommodated a large number of seats in the auditorium, large volume, the location of the horse (the installation height of the lamps) will also increase accordingly. The range of installation height of the luminaire and the relationship with the movement level are shown in Table 2 to Table 3:

Note: The height of the luminaire is the height of the road, taking the highest height of the road.

Programmable DC Power Supplies

The CSP series Programmable DC Power Supply is upgraded and developed on the basis of iDealTek-Electronics' mature IGBT high frequency switching power topology and all-digital signal control loop. Featured with high precision, low ripple and fast response speed.
The Programmable DC Power Supply is different from the traditional DC power supply that can only control the output voltage and current values. The programmable DC Power Supplies can realize the programming of multiple parameters through adding the microprocessor unit with built-in control program, such as parameters like operating time, output rise time, protection response time, OVP and OCP etc. All can be set and programmed.
At the same time, the microprocessor unit also adds more functions to the power monitoring system, which can realize the query of the historical data of the test results, making the programmable DC power supply the best choice for laboratory test, production line manufacturing test, photovoltaic plate aging test and various cutting-edge applications with Programmable DC power supplies.

This series of Programmable Power Supplies have a total of 4 standard rated power levels, ranging from 1KW Desktop Programmable Laboratory power supplies to 3KW / 6KW / 10KW Rack-mounted Programmable DC power supplies. The maximum output voltage ranges from 600V to 1000V under different rated powers.

Beautiful appearance design with small and compact size, the whole series power supplies adopt silicone buttons, stepless knobs and LCD display on control panel layout. The output voltage, current, start / stop time, output rising rate, OVP, OCP and other parameter setting programming and reading of the Programmable Power Supplies can be easily and quickly completed through the front panel man-machine interface, up to 5 digits of high-precision programming and monitoring levels make the measurement results of the programmable DC power supply accurate and reliable, almost no need to use external power meters.

At the same time, the whole series of programmable DC power supplies are equipped with RS485 interface as standard, following the MODBUS-RTU international protocol, which can realize remote control programming, test results save and uploading to the master unit and status monitoring of the power supply.
