Modern Stadium lighting comes with many new features. Various sports associations have varied guidelines and requirements for stadium lights. Among these all, the lighting requirement of FIFA has been the toughest to satisfy. Thus, a stadium can satisfy all rules and regulations if it satisfies the 4K broadcasting regulations of FIFA. Find out about some of the top factors that you have to consider when you design LED lights for stadium courts
Horizontal Average Luminance
The uniformity of the Horizontal Average Luminance is the most fundamental and basic factor to consider. It means the amount of brightness that is spread over the ground, and the quality of vibrancy on the ground surface.
Vertical Average Luminance
The evenness of Vertical Average Luminance needs to be taken into account as well. It is actually for simulating the way the audience can see. This indicates that there would be 4 vertical sides for auditing:
- 0 degree vertical
- 90 degree vertical
- 180 degree vertical
- 270 degree vertical
It has been the toughest part, given the fact that basically the rise on one side can lead to a reduction on the other side. The uniformity of the Vertical Average Luminance to Sub Camera and Main Camera should also be seen. It is the way the camera is able to view the light and then play, which means TV broadcasting effects. The Sub Camera and Main Camera are both by a stadium’s long side, slightly at a higher level than the playing surface.
Today, Minium Ra80 happens to be essential. Many latest projects are making way to CRI ra90 in order to obtain better effect. Traditional CRI (Color Rendering Index) system has been designed for the eyes of humans. These days, a few TV stadiums and sports stadiums begin to apply a new TLCI system. This system is the same as CRI, but it has to be regarded more from the camera.
Neutral sunlight temperature of 5500 Kelvin is applied by most stadiums out there.
Light leakage rate, Glare rate
The Glare rate is not the auditing factor in lots of stadiums. However, it is a factor that can impact the real effect of the audience, player and stadium. Thus, it is essential to consider these in order to design a good LED lighting system.
It is also a vital point. The performance of most sports stadium lights is extremely good. As in case of a fresh LED stadium illuminant buildup, the rate of flickering is less than 0.3%. This can make slow motion amazing.
LED is known as the 4th generation of eco-friendly lighting source. This has the benefits of small size, long life, protection for the environment and saving of energy. LED flood light of 500W can substitute HID lamp of 1000W, and LE flood light of 1000W can replace HID that is up to 2200W. In 2019, an increasing number of sports fields have used LED sports field lights to substitute traditional lights, as the former can last for more time and save over 60% energy. These lights can start up on time. LED sports field illuminants can be expected to be mainstream sports field lights in the future.
