1. Core Requirements & Lighting Standards for Tennis Court Lighting
Before designing a lighting solution, it is essential to clarify the core requirements and relevant lighting standards of tennis courts. Different usage scenarios (professional competitions, amateur training, recreational activities) have different lighting requirements, which are mainly reflected in four key indicators: illuminance level, illuminance uniformity, glare control, and color rendering index.
1) Illuminance Level: The Foundation of Clear Vision
Illuminance level refers to the intensity of light received on the court surface, measured in lux (lx). The higher the illuminance, the clearer the players can see the ball’s trajectory. According to the international standard CIE 150:2019 and domestic standard GB 50034-2013, tennis court illuminance is divided into multiple levels based on usage scenarios:
-
Recreational/Community Courts: Suitable for daily leisure and amateur activities, requiring a minimum average horizontal illuminance of 200-300 lx.
-
Amateur Training/Club Courts: For amateur training and small-scale friendly matches, the minimum average horizontal illuminance should be 500-750 lx.
-
Professional Competition Courts (Non-televised): For formal professional competitions without TV broadcasting, the minimum average horizontal illuminance is 1000-1500 lx.
-
Professional Televised Competition Courts: 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, and the vertical illuminance (to ensure clear imaging of players and balls) should also be ≥ 1500 lx.
2) Illuminance Uniformity: Avoid Light-Dark Differences
Illuminance uniformity refers to the consistency of illuminance across the entire court surface. Poor uniformity will lead to obvious light-dark areas, making it difficult for players to judge the ball’s speed and trajectory accurately. The standard requires that the uniformity ratio (minimum illuminance/average illuminance) of the tennis court surface should not be less than 0.7 for recreational courts and not less than 0.8 for professional competition courts. For televised competitions, the uniformity ratio should be further improved to ≥ 0.9 to ensure consistent imaging effects across the entire 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. Tennis court lighting must strictly control glare, and the glare value (UGR) specified by the standard should be ≤ 22 for recreational and training courts, and ≤ 19 for professional competition courts. Especially for outdoor courts, we need to avoid direct light shining into players’ eyes; for indoor courts, we should 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 yellow or green) and the court surface. The standard requires that the color rendering index of tennis court lighting should be ≥ 80; for professional competitions, it is recommended to use lights with Ra ≥ 90 to ensure the most realistic color reproduction.
2. Tennis Court Lighting Fixture Selection: Why LED Lights Are the Best Choice
In the past, tennis courts mainly used traditional light sources such as metal halide lamps and high-pressure sodium lamps. However, with the development of LED technology, LED lights have become the mainstream choice for tennis court lighting due to their obvious advantages. When selecting LED fixtures, we need to focus on the following key parameters and product types:
1) Advantages of LED Lights Over Traditional Light Sources
-
High Energy Efficiency: LED lights have an efficacy of 130-180 lm/W, which is 3-5 times that of metal halide lamps. For a standard tennis court, using LED lights can save 50%-70% of electricity costs annually.
-
Long Lifespan: The service life of LED lights is 50,000-100,000 hours, which is 5-8 times that of traditional light sources. This greatly reduces the frequency of fixture replacement and maintenance costs.
-
Excellent Light Quality: LED lights can easily achieve Ra ≥ 80 (even Ra ≥ 90), with good color rendering performance. At the same time, they can be equipped with professional optical lenses to control light distribution and reduce glare.
-
Instant Start & Dimmable: LED lights start instantly without warm-up time, and support dimming (0-10V, DALI, or smart dimming). They can adjust the illuminance according to the usage scenario (e.g., reducing brightness for training and increasing brightness for competitions), further saving energy.
-
Environmental Friendliness: LED lights do not contain mercury or other harmful substances, and have low noise and no stroboscopic effect, which is more in line with environmental protection and health requirements.
2) Key Parameters of LED Fixtures for Tennis Courts
-
Power: The required power of LED fixtures depends on the court area and illuminance requirements. A standard single tennis court (23.77m × 10.97m) usually requires 8-12 LED fixtures. For recreational courts, 100-150W fixtures are suitable; for professional competition courts, 200-300W high-power fixtures are needed.
-
Beam Angle: The beam angle directly affects the light distribution. For tennis courts, it is recommended to use fixtures with a beam angle of 30°-60°. Narrow beam angles (30°-45°) are suitable for long-distance projection (e.g., installing fixtures on high poles), while wide beam angles (45°-60°) are suitable for short-distance coverage to ensure uniform illumination.
-
UGR Value: Choose LED fixtures with UGR ≤ 22 (recreational) or UGR ≤ 19 (professional) to ensure glare control. Fixtures with anti-glare lenses or honeycomb grids are preferred.
-
IP Rating: For outdoor tennis courts, LED fixtures must have a waterproof and dustproof rating of IP65 or higher to resist wind, rain, dust, and other harsh weather conditions. For indoor courts, IP44 or higher is sufficient.
-
IK Rating: Considering the possibility of collision or falling objects (especially in outdoor and public areas), it is recommended to choose LED fixtures with IK06 or higher impact resistance to ensure structural integrity and durability.
3) Recommended LED Fixture Types for Tennis Courts
-
LED Flood Lights: The most commonly used type for tennis courts, with strong directional light and long projection distance. Suitable for both outdoor and indoor courts, and can be installed on light poles around the court. It is recommended to choose flood lights with adjustable beam angles and anti-glare designs.
-
LED High Bay Lights: Suitable for indoor tennis halls with high ceilings (≥ 8m). They have uniform light distribution and can cover a large area, avoiding the formation of dark spots. Choose high bay lights with high efficacy and good heat dissipation performance.
-
Smart LED Lights: Equipped with sensors (motion sensors, light sensors) and smart control modules, they can automatically adjust the brightness according to the presence of people and ambient light. Suitable for community courts that are not used all the time, further improving energy-saving effects.
3. Tennis Court Lighting Layout Design: Key Principles & Practical Schemes
Reasonable lighting layout is the key to ensuring uniform illuminance and avoiding glare. The layout design should be based on the court size, usage scenario, and installation environment (outdoor/indoor). 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 court to ensure that the illuminance on the left and right, front and back of the court is consistent, avoiding uneven light distribution.
-
Avoid Direct Glare: Install fixtures at a height of ≥ 6m (outdoor) or ≥ 5m (indoor), and adjust the installation angle to ensure that the light does not directly shine into the players’ eyes (the angle between the light and the horizontal line should be ≥ 45°).
-
Sufficient Projection Distance: The distance between the light pole and the court boundary should be 1.5-3m to ensure that the light can fully cover the court surface without overlapping or missing areas.
-
Control Light Pollution: For outdoor courts, choose fixtures with light-shielding covers to avoid light spilling into surrounding residential areas or roads, causing light pollution.
2. Practical Layout Schemes for Different Courts
1) Outdoor Single Tennis Court Layout
Scheme: Install 8-10 LED flood lights on 4 light poles (2 poles on each side of the court). The light poles are set at the four corners of the court extension line, with a height of 6-8m. Each pole is equipped with 2-3 fixtures with different beam angles: use narrow beam angle (30°-45°) fixtures for long-distance projection to the center of the court, and wide beam angle (45°-60°) fixtures for short-distance coverage of the court edges. This layout can ensure uniform illuminance across the entire court, with a uniformity ratio of ≥ 0.7.
2) Outdoor Double Tennis Court Layout
Scheme: A double tennis court is wider (23.77m × 18.29m), requiring 12-16 LED flood lights installed on 6-8 light poles (3-4 poles on each side). The pole height is 8-10m to increase the projection range. Adopt a "staggered layout" to avoid overlapping light areas and ensure that the illuminance uniformity ratio is ≥ 0.8. For professional competitions, it is necessary to add fixtures at the ends of the court to enhance vertical illuminance.
3) Indoor Tennis Hall Layout
Scheme: For indoor courts with a ceiling height of 8-12m, use 16-20 LED high bay lights or flood lights. Adopt a grid layout (4×4 or 5×4) to evenly distribute the fixtures above the court. The distance between fixtures should be 3-4m, and the installation angle should be adjusted to avoid light reflection from the floor. At the same time, install light-absorbing materials on the ceiling and walls to reduce glare and improve light utilization efficiency.
4. Installation & Maintenance Precautions for Tennis Court Lighting
Scientific installation and regular maintenance can ensure the stable operation and long service life of the tennis court lighting system. The following are key precautions:

Regular Inspection: Check the fixtures, light poles, and cables every 6-12 months. Check for loose connections, damaged waterproof seals, and corroded parts. Replace damaged components in time.
-
Illuminance Recalibration: Recalibrate the illuminance of the court every 1-2 years. If the illuminance decreases by more than 20%, adjust the fixture angle or replace the fixtures to ensure that the lighting effect meets the requirements.
-
Smart System Maintenance: For courts with smart lighting systems, regularly check the operation of sensors and control modules, update the system software, and ensure that the smart functions (dimming, automatic on/off) work normally.
5. Energy-Saving & Smart Control Strategies for Tennis Court Lighting
While ensuring the lighting effect, optimizing energy consumption and realizing smart management are important goals of modern tennis court lighting. The following are practical energy-saving and smart control strategies:
1. Dimming Control Based on Usage Scenarios
Install dimmable LED fixtures and matching dimming systems (0-10V, DALI). Set different brightness levels for different usage scenarios: 30%-50% brightness for daily cleaning and warm-up, 70%-80% brightness for amateur training, and 100% brightness for competitions. This can save 20%-40% of electricity costs compared to constant brightness operation.
2. Motion Sensor & Light Sensor Control
Install motion sensors and light sensors on outdoor or community courts. The system can automatically turn on the lights when people are detected and turn off the lights after people leave (with a delay of 5-10 minutes). The light sensor can adjust the brightness according to the ambient light (e.g., reducing brightness on cloudy days and increasing brightness at night), avoiding unnecessary energy waste.
3. Centralized Smart Control Platform
For large-scale tennis clubs or sports centers with multiple courts, install a centralized smart control platform. Managers can remotely monitor the operating status of each court’s lighting system (voltage, current, power consumption) through a computer or mobile APP, and realize remote on/off, dimming, and fault alarm functions. This not only improves management efficiency but also facilitates energy consumption statistics and analysis.
4. Solar-LED Hybrid Lighting System (Outdoor Courts)
For outdoor courts in areas with sufficient sunlight, consider using a solar-LED hybrid lighting system. The system uses solar panels to charge the battery during the day, and the battery supplies power to the LED lights at night. This can completely or partially get rid of the dependence on the power grid, further reducing energy costs. It is recommended to choose high-efficiency solar panels and long-life lithium-ion batteries to ensure stable operation.
