According to the relevant standards of sports architecture in China, the stadiums can be classified according to the usage function and TV broadcast requirements according to Table 1.

It should be noted that the functional grading of different standards is different. For example, FIFA FIFA and IAAF IAAF adopt 5 grades, which are different from China's standards.

First, the standard value of site lighting in China

Comprehensive China's "Code for Electrical Design of Sports Buildings" JGJ354-2014, "Sports Design and Testing Standards for Sports Venues" JGJ 153-2007, "Use Requirements and Test Methods for Site Lighting Part 1: Outdoor Football Stadium and Integrated Stadium" TY/T 1002.1 -2005 and other standards, the relevant indicators will be introduced one by one.

1, horizontal illumination

The horizontal illuminance standard value of the site lighting shall comply with the requirements of Table 2.

Note: When there are two values ​​in the same cell in the table, the value of the main game area PA or the value of the baseball and softball infield before "/", the value of the total game area TA or the value of the baseball and softball field before "/".

2, vertical illumination

Grade III and below may not be used to assess the vertical illumination of the site illumination. The vertical illumination standard value shall comply with the requirements of Table 3.

Note: When there are two values ​​in the same cell in the table, the value of the main game area PA or the value of the baseball and softball infield before "/", the value of the total game area TA or the value of the baseball and softball field before "/".

The shooting and archery items are quite special. The standard value of the vertical illumination of the bull's-eye should be: 1000lx of grade III and below; 1500lx of grade IV and grade V; 2000lx of grade VI.

3, uniformity

The standard value of the horizontal illumination uniformity of the site lighting shall comply with the provisions of Table 4.

Note: In the same box in the table, the U1 value before “/” and the U2 value after “/”; the value of TA in the total area or the value of the field of baseball and softball in “()”, The value of the PA or the value of the baseball and softball infield.

The vertical illumination uniformity standard value of the site lighting shall comply with the requirements of Tables 5 and 6.

Note: In the same box in the table, the U1 value before “/” and the U2 value after “/”; the value of TA in the total area or the value of the field of baseball and softball in “()”, The value of the PA or the value of the baseball and softball infield.

4, light source chromaticity parameters

The color rendering index of the site illumination source is not less than 65, and the correlated color temperature is 3500~6500K. It is different from the level of the event, the TV broadcast, and the sports.

5, glare

The glare index GR value should meet the requirements of Table 7.

6, lighting calculation

The maintenance factor value for lighting calculation needs to be valued as follows:

1) Indoor site maintenance factor of 0.8;

2) The maintenance index of general outdoor places is 0.8, and the area with serious pollution is 0.7.

3) For outdoor stadiums in foggy areas, the impact of the atmosphere should be taken into account, and the atmospheric absorption coefficient should be taken as required in Table 8;

4) The allowable deviation of the design illuminance value should not exceed the illuminance standard value +10%.

Second, the standard value of international venue lighting

There are many kinds of international standards, and it is impossible to enumerate them one by one. This book lists the sports programs that are more popular in China and the international sports standards that have a wide influence. Other standards can be found in the "Sports Lighting Design Handbook".

1. FIFA Standard

The latest FIFA standard is the 2011 version of FIFA "Football Field", of which Chapter 9 is venue lighting. The standard values ​​of the lighting of the football field are shown in Table 9.

Note: The illuminance value in the table is the maintenance illuminance value;

2 Ev is the vertical illumination in the direction of the fixed camera or the field camera. The handheld camera and the rocker camera are collectively referred to as the field camera;

3 The glare value in each level of the site should be GR ≤ 50;

4 maintenance factor should not be less than 0.7;

5 It is recommended to use constant lumens technology.

It should be noted that the standard has been compiled by the developed countries of football, and the level and system of football matches in these countries are very perfect. The Class III “domestic competition” in the table is close to the “professional competition” in China; the “League and Club Competition” in the second level is a low-level competition, similar to the “amateur competition and professional training” in China.

2. IAAF Standard

The latest standards of the International Association of Athletics Federations IAAF were promulgated in 2008, the 2008 edition of the IAAF Track and Field Facilities Manual, of which Section 5.1 is about site lighting, and the standard value of the track and field venues is 10.

Note: 1 The glare value in each level of the site should be GR ≤ 50;

2 For the end camera, U1 and U2 within 5m before and after the finish line should not be less than 0.9;

The illuminance value in the table 3 is the minimum maintained average illuminance value, and the initial illuminance value should not be less than 1.25 times the illuminance value in the table.

Similar to football, the international standards for track and field are also compiled by developed countries in Europe and America. In Table 2, the third level "domestic and international competitions", although not broadcast on television, is a professional competition, which is close to the "professional competition" level in China; the "club competition" in the second level is also a low-level competition, belonging to the amateur competition. It is similar to the level of "amateur competition and professional training" in China.

3. International Tennis Federation's lighting standards for tennis courts

The International Tennis Federation's lighting requirements for tennis are shown in Table 11.

Note: (1) GR ≤ 50. Ra ≥ 65, color TV / HDTV / film broadcast best Ra ≥ 90, color temperature Tk = 5500K.

(2) The number in parentheses in the table is the best value.

4. International Basketball Association's lighting standards

The standard issued by FIBA ​​FIBA ​​in 2004 - "Official Basketball Rules 2004, Basketball Equipment", the lighting requirements are shown in Table 12.

Note: Slo-mo represents a triple-rate slow-motion camera; SDTV represents a standard camera; for a SLR camera, the color temperature is preferably 5500K~6000K. Ecam - illuminance in camera direction, FOV - coverage of the camera, Eave - average illumination, UG - illumination gradient.

5, Olympic swimming, diving and other standards

The lighting standards for the Olympic swimming competition are shown in Table 13.
