What does trespass refer to in lighting terminology?

In lighting terminology, trespass refers to light intended for a specific area entering another area. This concept is particularly important in the context of sport facilities, where intentional lighting design aims to illuminate specific zones, such as a playing field or court. When light trespasses, it can create unwanted illumination in adjacent spaces, potentially causing glare and distracting players, spectators, or even impacting nearby residential areas.

This understanding emphasizes the importance of proper lighting design and placement in facilities to minimize light pollution and maintain the intended visibility within designated areas. Controlling light trespass is essential for achieving desired lighting effects while also being considerate of the surrounding environment and mitigating any negative impacts on neighboring spaces.
