Football Field Lighting Installation: Floodlight Fixtures Install Guide(AFC)
1. Corners-column/tower Floodlight Array
To avoid excessive glare around the goal line,particular attention should be paid to the zone within 15°of either side of the goal line. Multiple luminaires,as used in column/tower installations,should not be placed in this zone.
2. Linear-roof Rim Lighting
When pitch illuminance is provided by means of a linear run of luminaires around the stadium roof rim structure,the luminaires should be positioned with sufficient lateral distance to the pitch perimeter.
3. Player Face Modelling
The luminous flux must arrive upon players at the correct angle to provide the required face modelling.Dark shadows across players faces should always be avoided irrespective of the direction in which they are facing.
4. Column Positions
A corner columns should be positioned in the correct position in order to provide the illuminance conditions that will be effective. Generally corner columns should not be used for AFC Lighting Category1stadiums unless additional luminaires are installed around the perimeter.
5. Corners-linear Floodlight Array
If the installation design requires luminaires to be positioned within 15°of the goal line,the luminaires'focal point should be outside the penalty area.Luminaires positioned outside the 15° zone may be focused on the penalty area.This is only suitable for linear flood light arrays.
6. Pitch Perimeter-lateral Distance
An adequate lateral distance between the luminaire installing positions and the goal lines and side lines should be maintained in order to achieve the required vertical illuminance level around the perimeter of the pitch.
7. Pitch Perimeter-luminaire Installing Zone
Asageneral guide,the luminaires should be installed at an angle of no less than 25°and no more than 45°above the centre of the pitch.
8. Pitch Perimeter-second Linear Row
The luminaires should be installed at an angle of no less than 25° and no more than 45°above the centre of the pitch.In order to achieve improved vertical illuminance around the perimeter of the pitch,it may be necessary to install an additional linear row of luminaires with a greater lateral distance from the pitch.
9. Luminaire Focus Point Angle
In order to avoid discomfort glare being experienced by players and officials,a general rule during the design process is to ensure that luminaires'focus point angle is less than 70°from the line perpendicular to the pitch.
10. Pitch Sides-luminaire Installing Position
It is not acceptable for any stadium structures to impede the luminous flux of the pitch lighting system and cause shadows to be cast on the pitch.
11. Behind Penalty Area-luminaire Installing Zone
To maintain good visual conditions both for attacking players in front of the goal and for the goalkeeper,luminaires should be installed more than 6O°from the goal line when in line with the penalty area.
12. Behind Goal line-luminaire Installing Zone
Luminaires positioned behind the goal and parallel to the penalty area should be installed greater than 6O°from the goal line.
13. Behind Goal Line-second Linear Row
Anadequate lateral distance between the luminaire installing position and the goal lines should be maintained in order to achieve the required vertical illuminance level around the perimeter of the pitch.In some cases,a second linear run of luminaires may be installed under a stadium roof canopy to assist in this area.
