Which system utilizes sunlight to illuminate a playing surface?

The system that utilizes sunlight to illuminate a playing surface refers to ambient lighting. Ambient lighting encompasses natural light derived from the sun, which is a fundamental source for illuminating outdoor environments, including sports facilities. This type of lighting is crucial for activities that take place during the day, as it provides adequate and even illumination across the playing surface without the need for artificial lights.

In the context of sport facility management, understanding the importance of leveraging natural light can lead to more sustainable practices, such as reducing energy consumption and creating a more pleasant outdoor atmosphere for athletes and spectators. Hence, ambient lighting is essential in maximizing the functionality of outdoor sports facilities during daylight hours.

Other lighting types like fluorescent, incandescent, and LED are artificial methods that rely on electricity. While they contribute significantly to indoor lighting and can be used in facilities, they do not utilize sunlight, which distinguishes ambient lighting as the correct choice in this context.
