The number of LED stadium lights required for a soccer field depends on several factors, including the field size, level of play (e.g., training, amateur, professional, or broadcast), required illuminance (measured in lux), and the specific lighting design and fixtures used. Here's a synthesis of the information from the search results:
Key Factors Affecting the Number of Lights:
Field Size:
Standard 11-a-side soccer field: Typically 100–110 meters long and 64–75 meters wide .
Smaller fields (e.g., 5-a-side or 7-a-side) require fewer lights.
Level of Play and Illuminance Standards:
Illuminance requirements vary based on the level of play :
Training and recreational activities: 200 lux
Amateur matches: 500 lux
Professional matches: 750 lux
General TV broadcast: 1,000 lux
High-definition TV broadcast for large international matches: 1,400 lux or higher
TV emergency broadcast: 750 lux
Lighting Design and Fixture Specifications:
Wattage and efficiency: LED fixtures typically range from 240W to 1,200W, with higher-wattage fixtures covering larger areas.
Light distribution: The design (e.g., pole height, placement, and number of fixtures per pole) affects coverage and uniformity.
Pole height and arrangement:
For 11-a-side fields, pole heights usually range from 15m to 25m .
Common arrangements include:
Four-corner placement: 4 poles with multiple fixtures per pole.
Six-pole placement: 6 poles along the sides of the field (e.g., 3 per side).
Eight-pole placement: 8 poles around the field for higher uniformity 67.
Estimated Quantities for an 11-A-Side Soccer Field:
Based on the search results, here are some practical examples:
Training/Recreational Use (200 lux):
Example: 84 units of 300W LED fixtures (e.g.,BENWEI LED stadium light ) installed on 6 poles (14 fixtures per pole), totaling 25,200W, achieving ~200 lux 1.
Amateur Matches (500 lux):
Example: ~112 units of 1,000W LED fixtures for a field with tracks (170m x 90m) 2.
High-Definition TV Broadcast (1,400–1,700 lux):
Example: ~208 units of 1,000W LED fixtures for a 110m x 68m field .
Other Configurations:
for a standard football field (105m x 74m) specified 84 units of ≥240W LED lights (total ≥20,160W) to achieve >125 lux average illuminance .
General Guidelines:
Smaller Fields:
5-a-side field (~38–42m x 18–22m): Typically 6–8m poles with fewer fixtures .
7-a-side field (~65–68m x 45–48m): 12–15m poles with moderate fixtures .
Efficiency Considerations:
LED fixtures with higher efficacy (e.g., ≥160 lm/W) may reduce the number of fixtures needed .
Design software (e.g., DIALux) is often used to simulate and optimize lighting plans .
Summary Table for 11-A-Side Field:
| Use Case | Target Lux | Estimated LED Fixture Count | Fixture Power | Total Power | Pole Arrangement | Source |
|---|---|---|---|---|---|---|
| Training/Recreational | 200 | 84 | 300W | 25,200W | 6 poles (14/pole) | 1 |
| Amateur Matches | 500 | ~112 | 1,000W | ~112,000W | Not specified | 2 |
| HD TV Broadcast | 1,700 | ~208 | 1,000W | ~208,000W | Not specified | 2 |
| General Broadcast | 1,000 | Varies | 600–1,200W | Varies | 4–8 poles | 6 |
Consult Professionals: Lighting design should adhere to standards (e.g., FIFA, IES, or local regulations) and use simulation tools 26.
Consider Fixture Quality: High-quality LEDs with proper optics (e.g., precise beam control, glare reduction) can improve efficiency and reduce quantities 26.
Maintenance and Flexibility: Choose fixtures with long lifespans (e.g., 50,000 hours) and options for dimming or zoning for different events 16.
For a precise estimate, provide specific field dimensions and intended use, and consult a lighting designer or use software simulations.
