What considerations are needed for sports field lighting?

As people’s awareness of national fitness continues to increase, many places have begun to build sports venues. Lighting, as an essential part of sports venues, has become increasingly important, and the application of LED sports professional lighting fixtures has also received more attention. This article will guide you through what to consider when designing lighting for sports venues.

The principles of sports field lighting are relatively simple: to ensure safe use, technological advancement, economic reasonableness, and energy-saving, while meeting the needs of various users such as athletes, referees, and spectators. Additionally, if TV broadcasting is involved, the lighting must also meet the requirements for television broadcasting.

How can sports field lighting be safely used?

Safety should be a top priority when designing and installing sports field lighting to prevent accidents from occurring. Sports field lighting fixtures should come equipped with or be accompanied by angle adjustment indicators. This allows construction personnel to adjust the lighting angle of the fixtures accurately based on the sports field lighting design, facilitating quick installation and adjustment of the fixtures, thereby reducing the time spent working at heights.

Sports field lighting fixtures installed at high elevations should be lightweight, compact, and have a low wind load coefficient. The locking device of the sports field lighting fixture should be able to withstand the maximum wind load under operating conditions. The structural strength, stiffness, and service life of the lighting pole should comply with relevant national design standards. If the windward area of the sports field lighting fixture is too large and the structural strength of the lighting pole is insufficient, there is a risk of the lighting pole being blown down or bent in high winds. Therefore, it is important to select sports field lighting fixtures and poles that meet safety standards and can withstand harsh weather conditions.

The safe use of stadium lighting also requires green and healthy lighting. Nowadays, it is an era that pursues healthy lighting, which demands that the stadium lighting should be free of glare, blue light hazards, and stroboscopic effects.

How can sports field lighting be technologically advanced?

LED sports lighting can achieve stepless dimming and quick automatic adjustment of brightness through real-time control, and has multiple self-protection functions. It can seamlessly integrate with intelligent lighting systems, is easy to debug and operate, is compatible with existing lighting systems and open, safe, and stable network communication, and is easy to connect to mainstream IoT platforms, which saves users installation time and costs as well as post-maintenance and operation costs.

How can sports field lighting be economically reasonable and energy-saving?

Firstly, the stadium lighting fixtures should achieve high light efficiency, such as the Huaxia Beidou Star stadium lighting fixtures with a light efficiency of up to 130lm/w, to maximize the conversion rate of electrical energy. The protection level of the outdoor stadium lighting fixture casing should not be lower than IP55, and for places that are difficult to maintain or have serious pollution, the protection level should not be lower than IP65, to reduce the difficulty of stadium lighting maintenance and decrease maintenance costs.

During the design phase of sports architecture, the requirements for the stadium lighting design should be considered at the same time to avoid a passive lighting design plan after the completion of the main structure of the sports venue. No matter where the stadium lighting fixtures are installed, ideal lighting conditions cannot be achieved. For spaces with low ceilings and no TV broadcasting requirements, symmetrical lighting fixtures should be used for the top layout of the stadium lighting design. For sports venues with high vertical illuminance requirements and TV broadcasting requirements, non-symmetrical lighting fixtures should be used for the layout on the horseway. The position of the lighting fixtures should not affect the main sightline of the athletes, and the aiming angle of all lighting fixtures should be between 25° and 65°. The angle between the projection line of the connecting line between the endpoint of the horseway and the midpoint of the field baseline and the baseline should be greater than 30°. For large comprehensive sports venues, lighting fixtures with multiple lighting forms should be used for a mixed layout of the stadium lighting design.

Other considerations for sports venue lighting should be included!

In addition to lighting the playing area, sports venue lighting should also consider lighting for spectator seating and emergency situations. The purpose of lighting for spectator seating is not only to satisfy the general need for seeing seats clearly but also to meet the camera requirements for television broadcasting, including close-ups and slow-motion replays of important officials and celebrities. Sports venues are often large in size, accommodating thousands or even tens of thousands of people. As such, ensuring the safe entry and exit of large crowds is extremely important, especially in emergency situations where emergency lighting is essential. The average vertical illuminance of the first 12 rows of seating facing the playing area with television broadcasting requirements should not be less than 10% of the average vertical illuminance in the direction of the main camera. The average horizontal illuminance value of the platform should not be less than 200lx, and the minimum horizontal illuminance value of the spectator seating should not be less than 50lx.
