Basketball court lighting standards

 

The lighting of stadiums is an important content of stadium design and is more complicated. It must not only meet the requirements of athletes for competitions and audience viewing, but also meet the requirements for lighting color temperature, illuminance, and uniformity of illuminance for live TV broadcast. This requirement is much higher than that of athletes and audiences. In addition, the lighting method needs to be closely matched with the overall planning of the stadium and the structure of the stands. In particular, the maintenance of lighting equipment is closely related to architectural design and must be fully considered.
