[Technology] Talking about the requirements of basketball court lighting standards and the way of lighting

　　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  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  architectural design and must be fully considered.

　　【Lighting method】

　　1. Light pole cloth lamp: the lamp is installed on the light pole, generally 1~2 lights are installed on each light pole. This method is used in outdoor courts.

　　Generally, a four-pole arrangement or a six-pole arrangement is used. The lamp poles are placed as shown in the figure. The installation height of the lamp is greater than 7m, and floodlights are used  achieve better uniformity.

　　2. Starry sky lights: the lamps are arranged above the site, and the beam is perpendicular  the plane of the site

　　Advantages: high horizontal illuminance, uniform illuminance, and small glare

　　Disadvantages: low vertical illumination, inconvenient installation and maintenance

　　Application: This method is mostly used in basketball training halls, or indoor venues in schools, facries, and places that do not require high vertical illumination.

　　3. Horse road lighting: lamps are arranged on both sides of the field, and the beam is not perpendicular  the plane of the field

　　The aiming angle of the lamp is not more than 65 degrees, preferably less than 60 degrees, for the purpose of preventing glare.

　　Advantages: high vertical illuminance, uniform illuminance, convenient installation and maintenance

　　Disadvantages: greater glare

　　Application: This method is mainly used for indoor basketball gymnasiums with TV broadcast requirements, and it is also suitable for basketball training gymnasiums. Because of its simple installation and convenient maintenance, it is more and more widely used.
