NFL Field Lighting Standard
The NFL requires 5600 Kelvin of CCT.
The current NFL sports field lighting standards include:
- 2500 lux for NFL.
- 1500 lux for collegiate-level
- 500 lux for high school football fields.
The rugby field lighting increases the area where lamps cannot be arranged, which is intended to protect players and referees from the effects of glare. When there is a TV broadcast, the space within 15° on both sides of the bottom line. When there is no TV broadcast, the space within 10° on both sides of the bottom line.
Generally, the light-belt arrangement uses several kinds of projector lamps with different beam angles to project. The narrow beam is used for long-range projection, and the medium beam is used for short-range projection. The shortcomings of the light-belt arrangement are: the technology for controlling glare is stricter, and the physical feeling of the object is slightly worse.
The choice of lamps is also very important for rugby games. A few years ago, rugby field lights were generally metal halide lamps. However, in the course of use, problems continued to cause considerable troubles on the rugby field, such as glare, Frequent lighting quality problems caused by spilled light and heating of lamps have seriously affected the conduct of professional rugby matches.
After that, the stadium has updated the rugby field lighting, replacing the metal halide lighting with more advanced LED sports lighting. In the field of football field lighting, Tachyon occupies a unique position. It is understood that the sports lighting company in China to provide international large-scale sports events. Before that, they appeared in the world sports competitions as the lighting supplier for the 2014 Russian Winter Olympics!
Tachyon lighting fixtures are a new generation of green lighting system, which minimizes the light pollution to the surrounding environment, effectively prevents overflow and glare, reduces the light outside the venue as much as possible, protects the beautiful night sky, and also provides rugby for athletes and spectators The field lighting creates a more comfortable competition and viewing environment.
Outdoor Stadium Lighting Standards
Outdoor stadium lighting overflow problem
In some indoor court lighting design, the light reflection ability of the roof is taken into consideration and the reflected light is fully utilized. In some indoor court design schemes, in order to make the light more uniform, the light reaches the roof, and then the light is reflected. Brighten the stadium.
However, outdoors, there are no ceilings and walls to reflect the light of the lamps, and it is easy to illuminate the objects around the stadium. This phenomenon of illuminating the areas that should not be illuminated in the design is called overflow light. The production of spilled light means that the cost-effectiveness of outdoor stadium lighting is not high enough, and part of the light is wasted. In addition to a waste of resources, spilled light can easily cause interference with spilled light. If the light shines into the sky, it will destroy the quiet night sky, and if it shines on the surrounding residential areas, it will interfere with the normal rest of the residents.
When the stadium light interference is severe to a certain extent, even the use of curtains or blinds cannot guarantee the darkness of the indoor sleeping environment. Sleeping in a bright environment for a long time will prevent the brain’s nerves from getting real rest, causing neurasthenia and disturbing the production of melatonin (sleep hormone), and these effects are accumulated over time.
The Layout of Outdoor Stadium Lighting Poles
The installation methods of outdoor stadium lighting lamps mainly include installation on horse tracks and light poles. The situation of installation on the horse track is mainly in the stadium with auditorium, and the lighting is installed on the horse track on the auditorium. The rest is basically installed on the light pole. The height of the light pole of the basketball court is basically between 8 and 15 meters, the height of the light pole of the volleyball court is basically between 8 and 15 meters, and the height of the light pole of the futsal field is basically between 8 and 15 meters.
The height of the poles of the stadium is basically between 8 and 15 meters, the height of the poles of the seven-a-side football field is basically between 12 and 20 meters, and the height of the poles of the eleven-a-side football field is basically between 15 and 25 meters. The height of the poles of the field is basically between 25 and 35 meters. It can be seen that the outdoor stadium lighting poles are not low, so the outdoor stadium lighting should not be too heavy, the windward surface should not be too large, and the number of lamps hanging on a pole should not be too many.

NFL Field Lighting Arrangement
The spread of rugby in the world is not very wide. Everyone knows a little about rugby, and is even more ignorant of the supporting facilities of rugby. Today, the editor will share with you what is the meaning of the light strip layout in football lighting.
Light strip arrangement is another form of two-sided arrangement, that is, the lamps are arranged in rows on both sides of the stadium to form a continuous light strip lighting system. The light band is evenly illuminated, and the brightness between the athlete and the court is better. At present, it is recognized in the world that this lighting method can meet the requirements of color TV rebroadcast, high-definition TV rebroadcast and even ultra-high-definition TV rebroadcast.
The length of the light strip is generally not less than 180m for Grade A and Super football stadiums, and the projection angle of the lamps should not be less than 25°. Some rugby field light strip lighting is very close to the edge of the field (the angle is above 65°), and the side of the field closer to the light strip cannot obtain sufficient vertical illuminance, so it is necessary to increase the rear lighting system.
