LED pitch perimeter display systems

Pitch perimeter display systems provide an opportunity to tailor advertising and stadium management information to each individual event.
UEFA’s LED pitch perimeter board guidelines should be consulted prior to broadcasts. The LED advertising system should be assessed on installation and tested prior to each broadcast event. The LED display panel should operate within UEFA guidelines so as not to affect the camera balance or exposure during the match coverage.
The basic minimum technical specifications are listed below and will be valid until 2018:
LED configuration: 3-in-1 SMD
Screen height: Minimum of 90cm; maximum of 100cm
(maximum height more for existing systems to avoid losing seats)
Total length: Minimum length of 246m; ideal length of 257m
Pixel pitch: Ideal minimum quality level: 12.5mm x 12.5mm (real)
(pitch can be symmetrical or asymmetrical)
Horizontal viewing angle: Minimum of 140°
Refresh rate: Minimum of 2,800Hz
Luminance: Minimum of 5,500Nit
Data feeds: Control signal connection via two redundant feed points;
data ring loop configured
For further information, consult the latest version of the guidelines or contact UEFA.

TV broadcast camera plan

It is important that people designing lighting systems for football stadiums understand the requirements of television cameras and the positions that they operate from. Below is a typical camera plan for a highspecification TV broadcast of a football match:

Key to camera plan

That camera plan is fairly typical, but some broadcasters and TV directors will deviate from it slightly. The purpose of the plan is to help you understand how the different elements of the lighting design should be used to ensure the correct illuminance conditions in all areas of the pitch.

Environmental guidance

There are a number of bodies that provide certification for buildings which are designed and constructed in line with strict sustainability guidelines. The most prominent of these bodies are BREEAM (in Europe) and LEED (in the US). Both of these bodies provide an extensive list of parameters and checklists which need to be followed and implemented, after which the designated certification body assesses the level of compliance and issues the appropriate certification for the building. Both UEFA and FIFA recommend that all modern stadiums adhere to the standards stipulated by one of these two certification bodies. However, it is ultimately down to the stadium developers themselves to (i) be fully aware and supportive of the need for an environmentally responsible approach, (ii) proactively include sustainability initiatives within the project brief and (iii) direct the design consultants accordingly.

Environmental impact of illuminance

Many countries will have regulations and guidelines aimed at ensuring that the quantity of stray illuminance does not have an undue impact on the local community.
The type of stadium structure and pitch illuminance system will determine the level of illuminance that is produced in areas outside the stadium. A report should be produced with adequate reference points in areas around the stadium showing the illuminance levels created by the pitch illuminance system on the horizontal and vertical planes. The report should comply with the guidelines produced by the relevant authorities and be submitted for their approval.
For reference purposes, pitch illuminance systems should not produce illuminance levels greater than 50 lux on the vertical plane at a height of 1.5m and a distance of 50–200m from the stadium perimeter. For lowerilluminance level stadiums the stray light produced by the pitch illuminance system should be lower.

Environmental impact of glare

The pitch illuminance system should be designed in such a way that it does not produce levels of disability glare or discomfort glare that could cause disturbance to people within the local community. Particular attention should be devoted to ensuring that no drivers of vehicles on adjacent roads are affected by the pitch illuminance system.

UEFA Pitch Illuminance Test Report introduction

UEFA uses illuminance test reports to assess the illuminance conditions at venues. Tests should only be carried out by qualified personnel using the correct equipment. Equipment must have been recalibrated within the last 12 months.
The UEFA Pitch Illuminance Test Report can be found across pages 55-62 of these guidelines.
UEFA Pitch Illuminance Test Report
UEFA requires that all venues which could potentially host a televised match undergo assessments of their pitch illuminance systems.
Such illuminance tests must be conducted in accordance with UEFA’s guidelines to ensure a consistent and objective analysis of the illuminance conditions at all relevant stadiums.
The illuminance test procedure and requirements are detailed below.
Inspection equipment
The illuminance meter used for the illuminance test should be suitable for a floodlighting environment, with a wide angle receptive light sensor. The meter must be recalibrated on an annual basis.
Test procedure
A football pitch measures 68m by 105m. This area is divided up into a grid containing 96 points. At each point, an illuminance test is carried out to measure both the horizontal illuminance and the vertical illuminance at four different angles. Thus, the test will require 480 illuminance tests in total. Please ensure that the correct orientation is used when marking out the grid positions. The orientation can be seen in the pitch orientation plan.
Care should be taken when recording illuminance readings. The illuminance meter should always be positioned at the correct angle for the intended measurement. Personnel carrying out the test must not create any shadows that could impinge upon the illuminance meter. The meter should be 1m above the playing surface.
The illuminance reading for each grid point should be recorded on the relevant illuminance grid plan. Horizontal test: The meter is positioned facing upwards, 1m above the playing surface, and parallel to the pitch, at every grid point.
Vertical test: The meter is positioned perpendicular to the pitch, 1m above the playing surface, at every grid point. The meter should then be adjusted for each of the four test positions. The test positions are indicated on the vertical illuminance grid plan and are at 0°, 90°, 180° and 270°. This procedure should be repeated at all 96 grid points.
