The illuminance (lux) required for a football field depends on the level of competition, TV broadcast requirements and international standards. The following are the illumination standards for different scenarios:
1. International standards (based on FIFA/CIE/EN 12193)
Competition level Illumination requirements (lux) Applicable scenarios
Training/amateur competition 100-300 lux Amateur training, informal competition
Amateur league 300-500 lux Local competition, low-level professional league
Professional competition 500-750 lux Professional league, national competition
TV broadcast (HD) 1000-1500 lux Domestic TV broadcast, international friendly matches
HD/4K broadcast 1500-2000 lux World Cup, Champions League and other top events (FIFA recommended)
Nighttime large-scale events 2000-2500 lux Olympics, World Cup finals (super high requirements)
2. Specific standards of different organizations
FIFA (International Football Federation)
General competition: ≥ 500 lux
TV broadcast: ≥ 1000-1400 lux
HD broadcast: ≥ 1500-2000 lux
UEFA (UEFA)
UEFA Champions League: ≥ 1400 lux (main camera area)
Uniformity (U1) ≥ 0.7, avoid shadows and glare
Chinese Football Association (CFA)
Chinese Super League: ≥ 1200 lux
Asian Champions League: ≥ 1500 lux
3. Uniformity and glare control
Uniformity (U1=minimum/maximum): ≥ 0.7 (FIFA requirement)
Glare index (GR): ≤ 50 (avoid affecting athletes and spectators)
Color temperature: recommended 4000K-6000K (natural white light, suitable for TV broadcast)
4. Practical application suggestions
Amateur stadium: 100-500 lux (low-cost LED or metal halide lamp)
Professional stadium: 1000-2000 lux (high-power LED floodlights, such as 1500W/2000W)
World Cup-level stadiums: 2000-2500 lux (multi-level lighting + intelligent dimming system)
5. How to calculate the number of lamps?
Refer to the previous calculation (1500 lux requires 140-220 LED lamps, depending on the power), but need to be combined with:
Light distribution of LED stadium lamps (narrow beams are more suitable for long-distance projection)
Installation height (25-50 meters high pole lighting)
Professional software simulation (such as Dialux)
Ordinary games: 500-1000 lux
TV broadcasts: 1000-1500 lux
Top events: 1500-2500 lux
If a specific lighting plan is required, it is recommended to provide details such as stadium size, budget, and competition level for further optimization, you can consult lux from lux lighting designer http://www.benweilight.com
