How to Light Up a Baseball Stadium?

Baseball is a very popular sport all over the world, especially in the United States, Japan, and Mexico. They'll have all kinds of baseball leagues. For the main official FIBA competitions, the dimensions of the court are: 28 meters long and 15 meters wide, measured from the inner edge of the boundary line. So how to arrange lights for the baseball field?

1. Calculation of illuminance and uniformity inside and outside the field

The lighting requirements of the LED baseball stadium lighting are different from the lighting requirements of other stadiums. The area of the baseball field is about 1.6 times that of the football field, and the shape is fan-shaped. The average illuminance of the outfield is about 50%, so the uniformity of the illuminance in the outfield is a difficult point, that is, the illuminance value at the junction of the infield and the outfield must be taken into account. It is expected that the illuminance values of the infield and the outfield will be designed to have a significant difference, and it is more hoped that the boundary between the infield and the outfield will become a watershed of illuminance values, thereby reducing the illuminance value of the outfield area adjacent to the infield and shrinking the area The difference between the illuminance value of the arc-shaped edge area of the outer field is used to improve the uniformity of the illuminance of the outer field. When designing, the projection point and beam angle of each lamp must be selected and calculated one by one. If necessary, the height of the lamp pole must be adjusted to ensure that the various lighting indicators of the baseball field comply with the International Commission on Illumination (CIE) standards And the relevant standards of domestic venues.

The lighting design of the baseball field must not only meet the average vertical illuminance and average horizontal illuminance, but also must achieve the uniformity of vertical illuminance and the proportional coefficient of horizontal illuminance. In addition, it is necessary to limit the value of the glare index and select a light source with a higher color rendering index and corresponding color temperature, so as to meet the basic functional requirements of the illuminated baseball field. To ensure the normal skills of baseball players during night training and competition, and at the same time to ensure that when the color TV is broadcast, it can clearly reflect the players' instantaneous movements, movements and sports postures, and can capture the trajectory of baseball in high-speed motion.

2. Projection point determination and glare limitation

For the limitation of glare, it can be achieved from many factors such as the determination of the projection point, the adjustment of the height of the lamp pole, and the selection of the beam angle of the lamp. The four pole lights on the curved line of the baseball field all face the home base of the infield, so determining the illuminance value in the vertical direction is also easy to cause glare to the catcher. Therefore, it is a key point in lighting design to limit the glare index of the baseball field. It must be calculated one by one, calculated again and again, and modified one by one until the calculated value is satisfactory.
