1. Core Requirements & Lighting Standards for LED Football Pitch Lighting
Before designing an LED football pitch lighting solution, it is crucial to clarify the core requirements and relevant lighting standards. Different usage scenarios (professional competitions, amateur training, recreational activities, TV broadcasting) have significant differences in lighting requirements, which are mainly reflected in five key indicators: illuminance level, illuminance uniformity, glare control, color rendering index, and flicker index. These indicators are clearly specified in international standards such as CIE 150:2019 and domestic standards such as GB 50034-2013 and JGJ 153-2016.
1) Illuminance Level: The Basis of Clear Vision
Illuminance level refers to the intensity of light received on the pitch surface, measured in lux (lx). For football pitches, both horizontal illuminance (illumination on the pitch surface) and vertical illuminance (illumination on the vertical plane, critical for TV broadcasting and player vision) need to be considered. According to different usage scenarios, the illuminance level is divided into the following grades:
-
Recreational/Community Pitches: Suitable for daily leisure and amateur activities, requiring a minimum average horizontal illuminance of 150-300 lx, and no special requirements for vertical illuminance.
-
Amateur Training/School Pitches: For amateur training and small-scale friendly matches, the minimum average horizontal illuminance should be 500-750 lx, and the average vertical illuminance should be ≥ 300 lx.
-
Professional Non-Televised Competitions: For formal professional competitions without TV broadcasting, the minimum average horizontal illuminance is 1000-1500 lx, and the average vertical illuminance is ≥ 750 lx.
-
Professional Televised Competitions: The highest level of requirement, as TV broadcasting has strict demands on light stability and color reproduction. The minimum average horizontal illuminance should be ≥ 2000 lx, the average vertical illuminance ≥ 1500 lx, and the peak illuminance should not exceed 3000 lx to avoid overexposure in TV imaging.
2) Illuminance Uniformity: Avoid Light-Dark Differences
Illuminance uniformity refers to the consistency of illuminance across the entire pitch surface. Poor uniformity will lead to obvious light-dark areas, making it difficult for players to accurately judge the speed and trajectory of the ball, and affecting the viewing experience and TV broadcasting effect. The standard specifies two key uniformity indicators: overall uniformity (Uo = minimum illuminance/average illuminance) and local uniformity (Ul = minimum illuminance in a local area/average illuminance in the same area). Specific requirements are as follows:
-
Recreational/Training Pitches: Uo ≥ 0.6, Ul ≥ 0.7.
-
Professional Non-Televised Competitions: Uo ≥ 0.7, Ul ≥ 0.8.
-
Professional Televised Competitions: Uo ≥ 0.8, Ul ≥ 0.9, to ensure consistent imaging effects across the entire TV screen.
3) Glare Control: Protect Visual Comfort
Glare is the discomfort caused by excessive brightness contrast in the field of vision, which is a key factor affecting players’ performance and visual health, as well as the viewing experience of spectators. For football pitch lighting, the glare value (UGR) is used to evaluate the glare level. The specific requirements are:
-
Recreational/Training Pitches: UGR ≤ 25.
-
Professional Non-Televised Competitions: UGR ≤ 22.
-
Professional Televised Competitions: UGR ≤ 19, to avoid glare affecting the judgment of players and the clarity of TV images.
In addition, for outdoor pitches, it is necessary to avoid direct light shining into the eyes of players, referees, and spectators; for indoor stadiums, measures should be taken to prevent light reflection from the ceiling and walls.
4) Color Rendering Index: Restore True Colors
Color rendering index (CRI, Ra) measures the ability of light to restore the true color of objects. A high CRI is crucial for players to distinguish the color of the ball (usually white or yellow), the color of the jersey, and the boundary of the pitch. The standard requires that the color rendering index of football pitch lighting should be ≥ 80; for professional televised competitions, it is recommended to use lights with Ra ≥ 90 to ensure the most realistic color reproduction in TV broadcasting.
5) Flicker Index: Ensure Light Stability
Flicker refers to the periodic fluctuation of light output. Severe flicker will not only affect visual comfort but also cause ghosting in TV broadcasting, affecting the viewing effect. For LED football pitch lighting, the flicker index (FI) should be ≤ 0.03, and the stroboscopic frequency should be ≥ 100Hz. For professional televised competitions, it is necessary to use LED lights with ultra-low flicker (FI ≤ 0.01) to meet the requirements of high-definition TV broadcasting.
2. LED Stadium Light Selection for Football Pitches: Key Parameters & Advantages
Compared with traditional light sources such as metal halide lamps, LED stadium lights have obvious advantages in energy efficiency, light quality, lifespan, and controllability, making them the ideal choice for football pitch lighting.

3. LED Football Pitch Lighting Layout Design: Key Principles & Practical Schemes
Reasonable lighting layout is the key to ensuring uniform illuminance, avoiding glare, and meeting TV broadcasting requirements. The layout design should be based on the pitch size, usage scenario, installation environment (outdoor/indoor), and the number of light poles. The following are the core principles and practical layout schemes:
1. Core Layout Principles
-
Symmetrical Layout: Adopt a symmetrical layout on both sides of the pitch to ensure that the illuminance on the left and right, front and back of the pitch is consistent, avoiding uneven light distribution. For rectangular football pitches, the light poles should be arranged symmetrically along the long sides.
-
Avoid Direct Glare: Install fixtures at a height of ≥ 8m (outdoor small pitches) or ≥ 12m (outdoor large stadiums); for indoor stadiums, the installation height should be ≥ 10m. Adjust the installation angle to ensure that the light does not directly shine into the eyes of players, referees, and spectators (the angle between the light and the horizontal line should be ≥ 45°).
-
Sufficient Projection Distance & Coverage: The distance between the light pole and the pitch boundary should be 3-5m to ensure that the light can fully cover the pitch surface without overlapping or missing areas. For large stadiums, it may be necessary to install light poles at both ends of the pitch to enhance vertical illuminance.
-
Control Light Pollution: For outdoor pitches, choose fixtures with light-shielding covers and precise light distribution to avoid light spilling into surrounding residential areas or roads, causing light pollution. At the same time, adjust the installation angle to reduce upward light leakage.
-
Meet TV Broadcasting Requirements: For televised competition pitches, the layout should ensure that the vertical illuminance is uniform, and the light direction should be consistent with the TV camera angle to avoid shadows affecting imaging. It is recommended to adopt a multi-directional lighting layout to reduce the contrast between light and shadow.
2. Practical Layout Schemes for Different Football Pitches

Scheme: An 11-a-side football pitch (100m × 64m) requires 24-32 LED high-power flood lights installed on 8-12 light poles (4-6 poles on each side). The light pole height is 12-15m, and the distance between the light pole and the pitch boundary is 4-5m. Adopt a combination of narrow beam angles (30°-45°) and wide beam angles (45°-60°): use narrow beam angle fixtures for long-distance projection to the center of the pitch, and wide beam angle fixtures for short-distance coverage of the pitch edges. This layout can achieve an average horizontal illuminance of 1000-1500 lx, with a uniformity ratio of ≥ 0.7.
3) Outdoor 11-A-Side Professional Televised Competition Stadium Layout
Scheme: A large professional stadium requires 36-48 LED ultra-high-power flood lights or modular stadium lights installed on 12-16 light poles (6-8 poles on each side) and 4-6 light poles at both ends. The light pole height is 15-20m to increase the projection range and reduce glare. Adopt a multi-directional symmetrical layout, with fixtures arranged at different angles to ensure uniform vertical illuminance. The beam angle is controlled at 25°-40° to achieve precise light distribution. This layout can achieve an average horizontal illuminance of ≥ 2000 lx, an average vertical illuminance of ≥ 1500 lx, and a uniformity ratio of ≥ 0.8, meeting the requirements of high-definition TV broadcasting.
4) Indoor Football Stadium Layout
Scheme: For indoor stadiums with a ceiling height of ≥ 12m, use 32-48 LED high-power flood lights or stadium lights. Adopt a grid layout (8×4 or 10×4) to evenly distribute the fixtures above the pitch. The distance between fixtures should be 4-5m, and the installation angle should be adjusted to avoid light reflection from the floor and ceiling. At the same time, install light-absorbing materials on the ceiling and walls to reduce glare and improve light utilization efficiency. This layout can ensure uniform illuminance across the entire pitch, with a UGR value of ≤ 22.
