What Are The Design Requirements Of Baseball Stadium Lighting?

Baseball Stadium Lighting Design Requirements

1. Calculation of illumination and uniformity of internal and external fields

The lighting of a baseball stadium is different from the lighting requirements of other courts. The area of a baseball stadium is approximately 1.6 times that of a football field. The shape of the stadium is fan-shaped. The difference in illumination values between the inside and outside fields is very different. Generally speaking, the average illumination of the infield is higher. The average illuminance in the field is about 50%, so the uniformity of the illuminance in the external field is difficult, that is, the illuminance at the junction of the infield and the outfield is taken into account. It is expected that the illuminance values of the infield and the outfield will be designed to have significant differences, and it is more desirable to divide the boundary between the infield and the outfield into the watershed of the illuminance value, thereby reducing the illuminance of the outfield area adjacent to the infield, and reducing the area The difference between the illuminance of the arc-shaped edge of the field is used to improve the illumination uniformity of the external field. At the time of design, the projection point and beam angle of each lamp must be selected and calculated one by one. If necessary, the height of the lamp post must be adjusted to ensure that the various lighting indicators of the ballpark conform to the International Commission on Illumination (CIE) standards. And related standards for domestic venues.

Baseball field lighting design not only meets the average vertical illuminance and the average horizontal illuminance, but also must reach the proportionality coefficient of the vertical illuminance uniformity and the horizontal illuminance. In addition, it is necessary to limit the value of the glare index, select a higher color rendering index and the corresponding color temperature of the light source, so as to achieve the basic functional requirements of the light baseball stadium. It ensures the normal skills of baseball players during night training and competition, and at the same time ensures that when the color television is broadcast, it clearly reflects the athlete's instantaneous movements and movements and movement postures, and can capture the trajectory of the baseball in high-speed sports.
