FOOTBALL PITCH LIGHTING SOLUTION

1.Design Guide

The following points should be considered and applied when designing a new stadium illuminance system or making alterations to an existing system.

1.1 It is essential that players’ comfort and performance not be hindered by the stadium illuminance system.

1.2 The ability of match officials to perform effectively should not be hindered by the stadium illuminance system.

1.3 A spectator should be able to watch and enjoy the match without suffering any discomfort caused by the pitch illuminance system.

1.4 The stadium lighting system should provide a level of illuminance that agreed and illuminance for televised events shall meet the requirements of TV broadcasting if required.

1.5 A successful stadium illuminance system will produce illuminance levels and uniformity that comply with the requirements of the relevant lighting standard with soft shadows where possible.

1.6 The stadium illuminance system must be reliable and effective for the given location. The specific conditions that are relevant for the stadium location should be carefully assessed.

1.7 The stadium illuminance system should provide a cost-effective and efficient, long-term solution.

1.8 Every sports stadium is unique. Consequently, each stadium will require a design solution that is appropriate for the relevant stadium and illuminance level.

1.9 The stadium’s infrastructure and design will have a significant impact on the type of pitch illuminance system that can be applied. A four-corner tower/column system will not generally meet FIFA’s requirements for FIFA Lighting Standard A.

Anyone designing a lighting system should take account of the latest technological requirements for broadcast television.
