Football Stadium Lighting Design
Football lighting is divided into internal football field lighting and external football field lighting, and the installation method of lights varies depending on the venue. The lighting standards should be determined based on the functionality of the football field, which can be roughly divided into 6 levels, as shown in the table below.
Professional lighting for venues such as the Olym-pic Games, Asian Games, World Cup, rugby, baseball, professional league events, international large-scale event venues, HDTV television broadcasting level, football, basketball, large football fields, rugby fields, golf courses, ski slopes, racetracks, specialized basketball courts, and sports training grounds; Perfectly meeting the high-definition broadcasting needs of domestic and international events.
Professional sports lighting, stadium lighting, sports venue lighting, LED floodlights, outdoor high pole lights, basketball court night lighting, LED floodlights
*CRI>90, TLCI>90, R9>20;
*Pure aluminum integrated heat dissipation, fast heat conduction, and excellent heat dissipation performance;
*High power, small size, light weight, smaller windward area compared to traditional modular lights, and higher safety factor;

*Professional anti overflow light cover, effectively controlling overflow light;
*The protection level is IP66, IK08, resistant to strong winds of level 17, and fearless of harsh outdoor environments.
1. Illuminance
(1) The first requirement for illumination is to create good conditions for athletes to fully utilize their technical skills, and to enable the audience to see the athletes, spheres, equipment, and movements clearly, that is, to have good visibility. Illuminance should also be determined based on different usage requirements of sports events, sports venues, as well as factors such as the number of spectators and maximum viewing distance.
(2) The ideal lighting level for the competition venue is: the horizontal and vertical lighting levels are similar, not more than twice the vertical lighting level, as shown in the table below:
Recommended values for stadium illumination
2. Light source
The selection of light sources mainly considers factors such as luminous efficiency, lifespan, color temperature, light control ability, and economy. The performance of several commonly used light sources is shown in the table below.
Among them, metal halide lamps have been widely used internationally, with high luminous efficiency, strong light control ability, and color temperatures close to those in the evening. When the competition lasts from day to night, it not only allows athletes and spectators to quickly adapt to the lighting, but also does not affect television broadcasting, ensuring the quality of television images.

3. Lighting fixture layout
(1) Light poles are arranged at the four corners of the court to evenly distribute light according to the court, and the lights are arranged at the four corners of the court; Install 4 sets of lights, with 5 floodlights on each set of high pole lights.
(2) Four sets of light cloth and two sides of the football field are installed on each set of light poles with 5 metal halide projection lights, with a power of generally 1000W, 1500W, or 2000W metal halide light source appliances;
(3) Install 6 sets of lights around the stadium (6 sets of light poles with 2 lights per assembly)
(4) Evenly distribute light around and arrange lights in 8 groups (with 2 metal halide floodlights installed on each group)
2, Basketball court lighting design

A modern sports stadium must have a good lighting environment, ensure visual effects, and meet the lighting requirements of the audience, participants, and television broadcasts for the competition. So, do you really know how the lighting method of the sports stadium is designed?
1. Quadrangular arrangement
The four corner lighting fixtures are arranged in a concentrated form in combination with lamp poles at the four corners of the competition venue. Until today, the lighting facilities in many sports venues are still arranged at four corners, with four light poles set at the four corners of the venue, with a tower height of generally 35-60m. Narrow beam lamps are commonly used. This layout is suitable for football fields without a canopy or with a lower canopy height. This method has low lighting utilization, difficult maintenance and repair, and high cost.
The appropriate position of the lamp pole is shown in Figure 1, and the angle between the bottom row of floodlights and the center of the site and the ground should not be less than 25 ° to determine the height of the lamp pole. Therefore, the distance between the lamp pole and the center point of the site varies, and the height of the lamp pole also varies, as shown in Table 3; The triangle area formed by the intersection of the midpoint of the court baseline and the court baseline at a 10 ° angle outward (15 ° angle with TV broadcasting), and the extension line after the intersection of the midpoint of the court sideline and the sideline at a 5 ° angle outward is the location for arranging light poles. By using various projection lights with different beam angles, a suitable illumination distribution can be formed on the site.
Figure 1 Position of Four Corner Light Pole
The installation height of the lamp and the distance from the lamp pole to the center point of the site Note: in the table, h is the vertical distance from the lowest row of projection lights of the lamp shoot to the site, and the actual height of the lamp pole plus the height of the lowest row of lamp shoot.
However, today's television broadcasting requires higher and uniform vertical illumination, and the required angle of light incident on the farther part of the site is much smaller than the specified limit. The impact of using large gas discharge lamps to achieve higher brightness, coupled with the high height of traditional lighthouses (a type of lamp pole), inevitably leads to excessive glare.
The disadvantage of this type of four corner lamp layout is that the visual changes in different viewing directions are large, and the shadows are deep. From a color TV broadcast, it is indeed difficult to meet the vertical illumination in all directions while also controlling the glare. To meet the Ev/Eh ratio requirements and reduce glare, it is necessary to take some improvement measures for the four corner lighting method.
(1) Move the four corner positions to both sides and outside the boundary, so that a certain vertical illumination can be obtained on the opposite side and four corners of the field.
(2) Increase the number of floodlights on the lamp pole on the direction of the main TV camera to enhance beam projection.
(3) Add light strip lighting on the top of the stand in the direction of the main TV camera, and pay attention to controlling glare to prevent the audience at both ends of the venue from noticing it.
2. Multi pole arrangement
Multi pole arrangement is a form of arrangement on both sides, where lamps are combined with light poles or building tracks, and arranged in clusters or continuous light strips on both sides of the competition field. As the name suggests, the multi pole layout type refers to the installation of multiple sets of light poles (or poles) on both sides of the field, as shown in Figure 2, suitable for football practice fields, tennis courts, etc. Its outstanding advantage is that it consumes less electricity and has a good comparison between vertical and horizontal illumination. Due to the lower lamp pole, this type of lamp layout has the advantages of less investment and convenient maintenance.
Figure 2 Multiple Rod Arrangement
1- Lamp pole, 2- Stadium, 3- Stand
The light poles should be evenly arranged, with 4, 6, or 8 towers arranged. The projection angle should be greater than 25 °, and the maximum projection angle to the site boundary should not exceed 75 °.
This type of cloth lamp generally uses medium beam and wide beam projection lamps. If there is an audience stand, the arrangement of aiming points should be very meticulous. The disadvantage of this type of lamp arrangement is that when the lamp pole is placed between the venue and the audience, it will block the audience's line of sight, making it difficult to eliminate shadows.
In football fields without television broadcasting, the lateral lighting devices are mostly arranged in a multi pole layout, which is more economical, as shown in Figure 3. Usually, light poles are arranged on the east and west sides of the field. Generally speaking, the height of multi pole light poles can be lower than those arranged at the four corners. In order to avoid interference with the goalkeeper's line of sight, light poles cannot be placed within at least 10 ° on both sides of the baseline (when there is no television broadcast), using the midpoint of the goal line as the reference point.
Figure 3: Lateral arrangement of lighting fixtures in the field without television broadcasting
- Lateral corners; - Lateral six tower type; - Lateral eight tower style
The height of the lamp pole for multi pole lighting is calculated using a triangle that is perpendicular to the court and parallel to the baseline (see Figure 4), Φ≥ 25 °, and the height of the lamp pole h ≥ 15m.
Figure 4: Height of multi pole lighting poles in non television broadcast venues
Circular lighting fixtures are a special form of multi pole arrangement, mainly used for lighting in baseball and softball fields. It is best to use 6 or 8 light poles for the arrangement of lighting fixtures in baseball fields, while 4 or 6 light poles are usually used in softball fields. Lighting fixtures can also be installed on the raceway above the audience seat. The lamp pole should be located within a range of 20 ° beyond the main viewing angle of the four barrier areas, i.e. the lamp pole should not be set in the shaded area shown in Figure 4.
The height of the lamp pole must meet the requirement that the projection angle of the lamp should not exceed 70 °. According to North American standards, the height of the lamp pole is calculated as follows:
Light strip arrangement is another form of arrangement on both sides of the court, which involves arranging lamps in rows on both sides of the court to form a continuous light strip lighting system, as shown in Figure 6. The light strip lighting is uniform, and the brightness between athletes and the stadium is relatively good. Currently, it is widely recognized that this lighting method can meet the requirements of color television broadcasting, high-definition television broadcasting, and even ultra-high definition television broadcasting.
The length of the light strip should exceed the goal line by more than 10 meters. For Grade A and Special level comprehensive sports venues, the length of the light strip is generally not less than 180 meters, and the projection angle of the lighting fixtures should not be less than 25 °. Some sports venues have light strip lighting that is very close to the sideline of the venue (with an angle of over 65 °), and the side of the venue that is closer to the light strip cannot obtain sufficient vertical illumination, which requires the addition of a rear lighting system.
The International Football Federation FIFA issued a new version of the "Football Stadium" standard in 2011. The lighting of football stadiums has added areas that cannot be equipped with lighting fixtures, aiming to ensure that athletes and referees avoid the impact of glare. Specifically, the following parts (see Figure 7) cannot be equipped with lighting fixtures:
Firstly, with the midpoint of the baseline as the center, the space within a 15 ° angle range on both sides of the baseline when there is television broadcasting; The space within a 10 ° angle range on both sides of the baseline when there is no television broadcast.
Secondly, within the space behind the goal at an elevation of 25 ° in the center of the field.
Thirdly, based on the baseline, the space enclosed by an elevation angle of 75 ° on the outer side of the penalty area and an extension line of 20 ° on the shorter side of the penalty area, except for the area shown in Figure 7. Of course, the lighting fixtures in comprehensive sports venues are not subject to this restriction, but these restricted areas cannot be turned on during football mode.
The hybrid layout has the advantages of two types of lighting arrangements, enhancing the sense of entity, making the vertical illumination and uniformity in all four directions more reasonable, but increasing the degree of glare. At this point, the four corners are often not set up independently, but are unified with the building structure, resulting in lower cost.
The projection lights used in the four corners are mostly narrow beams, solving the problem of long-distance projection of light; The light band is mostly a medium beam or a narrow beam, achieving far, medium, and near projection. Due to the mixed arrangement, the projection angle and orientation arrangement of the four corners can be flexibly handled, the length of the light strip arrangement can also be appropriately shortened, and the height of the light strip can also be appropriately reduced.
