Introduction
The lighting system of a stadium is one of the most critical components, influencing not only the quality of the event but also the safety of participants and spectators. The placement of the horse track plays a crucial role in this context, as it directly affects both the quantity and quality of light, as well as energy consumption. The location of the track involves multiple disciplines such as architecture, engineering, and electrical systems, making it a complex decision-making process. However, many projects overlook the importance of proper lighting design, leading to inefficiencies and suboptimal outcomes.
In practice, improper positioning of the horse track often results in inadequate vertical illumination at the edges of the field, excessive glare, or insufficient lighting at the ends of the venue. These issues not only affect the performance of athletes but also impact the experience of the audience. Moreover, energy efficiency is another concern, with significant variations in power density values across similar venues. This research aims to address these challenges by proposing a systematic approach to determining the optimal placement of the horse track, ultimately improving the overall lighting design and sustainability of sports facilities.
1 Basic Requirements for Sports Lighting
Sports lighting must meet strict standards to ensure fair competition, high-quality broadcasts, and the safety of all participants. As sports events become more popular, the demand for better lighting increases. Athletes, referees, and spectators all require clear visibility under optimal conditions. Additionally, lighting design should support high-quality TV broadcasts, allowing viewers to enjoy the game without visual distractions.
Lighting regulations, such as JGJ153, outline specific requirements for the number and quality of lights in stadiums. Key considerations include avoiding direct glare, maintaining uniform illumination, and ensuring sufficient vertical lighting for cameras. These factors are essential for creating an environment where everyone can perform and enjoy the event effectively.
2 Factors to Consider in Horse Track Placement
2.1 Common Misconceptions in Design
One common mistake is placing the horse track inside the steel frame, which may seem aesthetically pleasing but can block light and reduce efficiency. Another misconception is overemphasizing the appearance of the track, which may lead to compromises in functionality. Proper placement requires balancing aesthetics with practical needs, ensuring that the track supports the lighting system without obstructing it.
2.2 Obstruction from Other Facilities
In some cases, ventilation ducts, cables, and other infrastructure can interfere with the lighting system if not properly planned. These elements must be considered during the early stages of design to avoid unnecessary complications and maintain optimal lighting performance.
2.3 Structural and Load Requirements
The horse track must be strong enough to support heavy equipment, people, and maintenance activities. It should have a minimum width of 1 meter and a clearance height of at least 1.5 meters. The rigidity of the structure is also important, as any deformation could affect the accuracy of the lighting angles, especially in high-level stadiums where precision is crucial.
3 Determining the Optimal Position of the Horse Track
Several factors influence the placement of the horse track, with the most important being its effect on the lighting quality. The relationship between horizontal and vertical illumination, as well as the projection angle of the lamps, plays a key role in achieving balanced lighting across the venue.
3.1 Horizontal and Vertical Illumination Relationships
For relay-level sports, the main and auxiliary cameras are positioned differently depending on the movement characteristics of the sport. The luminaire should be placed to provide adequate vertical illumination for both directions. The angles of projection are critical, with specific ratios required to ensure even lighting and minimize glare.
3.2 Projection Angle and Position Relationship
The projection angle of the luminaire significantly impacts key lighting metrics such as illuminance, uniformity, and glare index. Careful planning is needed to ensure that the horse track is positioned to optimize these factors while meeting the requirements of the event.
4 Determining the Position Parameters of the Horse Track
The position parameters of the horse track include the distance from the near side of the field, the height above ground, and the distance from the center point. These parameters are determined based on international standards and practical experience to ensure optimal lighting performance.
5 Shape and Number of Horse Tracks
The shape and number of horse tracks depend on the size and layout of the venue. Single-row or double-row configurations may be used based on the specific requirements of the event. The goal is to achieve the best possible lighting coverage while minimizing costs and maximizing efficiency.
6 Conclusion
Proper placement of the horse track is essential for effective stadium lighting. This research highlights the importance of considering various factors, including lighting performance, energy efficiency, and structural integrity. By following a systematic approach, designers can create better lighting solutions that enhance the overall experience for athletes and spectators alike.
