HOW TO MAKE A UNIFORMITY 0.87 LIGHTING SOLUTION FOR YOUR SOOCER FIELD?

As we all know,Uniformity of illumination is important for sports. It enables both the players and the spectators to easily follow the action, and it provides consistent lighting for the television cameras and photographers. Sports field lighting for internationally televised events must meet exacting standards, while more leeway is generally allowed for other events.

Ensuring uniformity is important in avoiding adaptation problems for both players and spectators. If uniformity is inadequate, certain objects or player details might be difficult to see from certain positions.

Uniformity is expressed as

the ratio of the lowest to the highest illuminance (U1 = Emin/Emax)

the ratio of the lowest to the average illuminance (U2 = Emin/Eaverage)

In non-televised situations, the uniformity of the horizontal illuminance is generally specified as between 0.6 to 0.7 (Emin/Eaverage) depending on sport and lighting class.

In televised situations, high uniformity is necessary for smooth and natural-looking scenes, especially in this era of HDTV; horizontal illuminance is generally 0.8, whereas vertical illuminance in the direction of fixed cameras requires a uniformity value of 0.7 (Emin/Eaverage).

Happy to share an example of 0.87 Uniformity :

It's one of our project in Germany,4poles of soccer field,we combined 20 and 40 degree beam angle lens,960W and 480W Led High Mast Lights,each pole 4pcs 960W 20Degree and 2pcs 480W 40Degree,make a unformity 0.87.
