The article discusses how to properly light sports facilities for both indoor and outdoor activities. It suggests that current lighting standards may need improvement and introduces new ideas like spatial illuminance to enhance lighting design. By examining the relationship between brightness and the amount of light (illuminance) on 3D objects, researchers proposed a ratio method to determine the right brightness levels. They found that a certain range of this ratio ensures sufficient brightness, providing a useful guideline for lighting design. In conclusion, by considering concepts like spherical, hemispherical, cylindrical, and semi-cylindrical illuminance, the study offers insights to help create optimal lighting conditions for sports.
