In recent years, with the improvement of living standards and strong government support for the sports industry, numerous modern sports facilities have been constructed or renovated. These venues are not only equipped with advanced sports equipment but also require optimal lighting conditions that ensure good visibility for athletes, referees, and spectators. Proper illumination is essential to meet the demands of different sports events, including television broadcasting requirements. This has led to specific design criteria for stadium lighting systems.
Stadium lighting involves several key technical parameters, such as illumination levels, color temperature, and light rendering. For example, the illumination uniformity ratio (minimum to maximum) should be at least 0.5. Fire emergency lighting must also be considered, typically set at 10% of the standard illumination level. The choice of light sources also plays a critical role, with color temperature and color rendering index (CRI) varying depending on the type of venue. Indoor spaces often use intermediate color temperatures (3300–5300 K), while outdoor areas may require cooler tones (above 5300 K).
Illumination calculations are crucial for accurate lighting design. Two main methods are used: the utilization coefficient method, which is suitable for early design stages, and the point-by-point calculation method, commonly applied during detailed construction planning. While the former provides an estimate, the latter offers more precision by accounting for the exact position and angle of each luminaire.
Lighting modes in indoor stadiums include direct, indirect, and mixed lighting. Each has its own advantages, such as low glare, high vertical illumination, or cost-effectiveness. Glare control is vital for both athlete performance and spectator comfort, often achieved through proper luminaire placement and anti-glare baffles.
Lamp selection is another important aspect. Metal halide lamps are frequently used due to their high efficiency, good color rendering, and long lifespan. However, fire emergency lighting requires instant activation, making halogen lamps a common choice. Special considerations are also needed for environments like swimming pools, where corrosion resistance and waterproofing are essential.
Modern lighting control systems now rely on computer-based automation, allowing for flexible and efficient management of lighting schemes. These systems can simulate lighting conditions, adjust settings remotely, and monitor performance in real time. Power supply arrangements are designed to ensure reliability, especially for large stadiums where backup power is critical.
A case study of Fujian Province’s swimming and diving hall illustrates these principles. It features high illumination levels, precise color temperature control, and an intelligent lighting system that supports multiple event types. Such projects highlight the importance of combining technical expertise with practical needs.
Additional considerations include grid lighting inside the stadium, which enhances architectural aesthetics and reduces glare, and the use of electrical accessory boxes to simplify maintenance and improve power factor. Fire accident lighting should be integrated with regular lighting systems for cost efficiency and easier fault detection.
As technology advances, the future of stadium lighting will continue to evolve, focusing on energy efficiency, safety, and adaptability. By embracing new innovations and learning from past experiences, lighting designers can create systems that meet both functional and aesthetic requirements.
