FIFA LED stadium light smart system supplier in Bolivia
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.

1. Light pole cloth light: the lamps are installed on the light pole, generally 1~2 lights are installed on each light pole, this kind of method is used for 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 lamps is greater than 7m, and floodlights are used to achieve better uniformity.
2. Starry sky lights: lamps are arranged above the site, the beam is perpendicular to the site plane Advantages: high horizontal illumination, uniform illumination, 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, factories, 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 to 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 television broadcasting 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.
