Do You Know The Lighting Arrangements In The Stadium's Four Corners?
May 05, 2018

A modern stadium is indispensable for a good lighting environment. It guarantees visual effects and satisfies lighting requirements for players such as players and spectators, contestants, and TV broadcasts. Then, do you know the lighting arrangements in the stadium's four corners?

Today, many stadiums are also equipped with four corner lighting facilities. Four poles are installed in the four corners of the venue. The tower height is generally 35-60m, and LED stadium flood light  are commonly used. This type of arrangement is suitable for football pitches with no shelter or lower pitches. Such methods have low lighting utilization, difficult maintenance and repair, and high cost.

However, today's television broadcasts require higher and more uniform vertical illuminance, and the required angle of light incident on the far part of the venue is far less than the prescribed limit. The effect of the higher brightness obtained by the use of a large-scale gas discharge lamp, together with the high height of a conventional lighthouse (a type of lamp post), inevitably causes excessive glare.

The disadvantages of this type of four-corner lighting are: the visual changes in different viewing directions are relatively large and the shadows are dark. From the perspective of color television broadcasting, it is difficult to control the glare in all directions. . To meet the Ev/Eh ratio requirement and reduce glare, it is necessary to take some improvement measures for the four-corner lighting.

(1) Move the four corners to both sides and outside the edge so that a certain vertical illuminance can be obtained across the field and the four corners.

(2) Increase the number of projectors on the pole of one side of the television main camera to increase the beam projection.

(3) To add LED stadium arena light to the top of the stands on the side of the main camera of the television, attention should be paid to controlling the glare, and audiences at both ends of the venue should not be detected.
