Simulation Analysis of Energy Saving in Stadium Lighting

In modern sports venues, the design of single and double horse tracks plays a crucial role in achieving optimal lighting conditions. By analyzing outdoor stadiums and integrated gymnasiums, illumination calculation software is used to simulate lighting scenarios based on recommended single and double lane configurations. The goal is to determine which track settings meet all lighting standards while minimizing energy consumption. The structure of Madao (horse track) as a lighting fixture is vital in stadium lighting. Its continuous layout, ease of installation, and convenient adjustment of lamp angles make it a popular choice among designers. However, due to the influence of building structures, there is often insufficient communication between architects and lighting designers during the setup of these tracks. This can lead to suboptimal positions and heights for the horse lanes, negatively affecting the overall lighting design. It is essential to consider the lighting needs during the initial planning phase of the horse road. A well-placed horse track ensures that all lighting indicators meet the required standards. Poorly chosen positions can result in significant issues later on, making it critical to plan carefully. This paper presents a simulation-based approach to evaluate lighting indices and power density for different track configurations. It focuses on parameters such as track shape and height, using examples from outdoor stadiums and integrated gyms. The aim is to calculate the necessary lighting power density while meeting all lighting requirements. **Horse Track Shape Selection** In this simulation, two types of horse tracks were considered: single and double. A single track involves placing one long path along the sidelines, while a double track uses two parallel paths. The placement of these tracks depends on the venue's geometry and structural constraints. For example, square or elliptical venues may require specific track shapes to ensure even lighting distribution. **Horse Track Parameter Selection** Based on established guidelines for setting up stadium lighting, specific parameters were selected for the simulation. These include the width (w), distance from the sideline (d), height above ground (h), and spacing (s). The data provided in the tables illustrates various configurations under different conditions, allowing for a detailed analysis of how each parameter affects lighting performance. **Installation Height and Calculation Parameters** Tables 1 through 4 present the relationships between installation height and various parameters for both single and double horse tracks. These include dimensions like width, distance from the sideline, and spacing between fixtures. The values vary depending on the type of venue—whether it’s a track and field area or a gymnastics hall. It’s important to note that the height of the horse track is measured from the ground to its highest point. In multi-purpose stadiums, the track may not be flat but instead follow the curvature of the building. This variation in height was taken into account during the simulation, with adjustments made to the fixture placements to reflect real-world conditions accurately. By thoroughly analyzing these factors, the study provides valuable insights into optimizing lighting efficiency while ensuring compliance with industry standards.
