Question 1

What key roles do professional stadium floodlighting systems play in matches?

Accepted Answer

A high-quality stadium floodlighting system can enhance the quality of matches in every respect:

It optimizes the visual environment for players, enabling them to track the ball quickly and perform precise ball control and changes of direction;

It provides uniform and stable lighting across the entire pitch, helping referees to clearly see on-pitch challenges and reducing the likelihood of incorrect decisions;

It fully illuminates the entire pitch, promptly revealing potential hazards such as debris and uneven surfaces, thereby reducing the risk of sports injuries.

Question 2

What are the core testing criteria for the stage of futsal lighting acceptance, and what do they represent?

Accepted Answer

The following key parameters must be tested during the acceptance inspection of professional five-a-side futsal pitch lighting:

Vertical illuminance: Measures illuminance on four vertical planes—0°, 90°, 180° and 270°—relative to the main camera, to ensure clear visibility for broadcast camera shots, players’ faces and the ball during high-speed movement;

Horizontal illuminance (Eh): The average illuminance on the horizontal plane of the pitch surface; this is the core indicator for assessing the pitch’s basic brightness;

Minimum Adjacent Uniformity (MAUR): Controls the difference in illuminance between any two adjacent measurement points to prevent the formation of bright and dark patches on the pitch;

Additional mandatory tests: Flicker coefficient, color rendering index, color temperature and glare value, which collectively ensure visual comfort for players and high-quality broadcast footage.

Question 3

Why must futsal lighting control both uniformity and glare simultaneously?

Accepted Answer

From a physical perspective, uniformity and glare are naturally in a ‘see-saw relationship’, but optimizing one at the expense of the other will not result in a perfect lighting solution. If the number of luminaires or their power is increased indiscriminately to improve uniformity, whilst neglecting the beam angle, this will significantly increase direct glare in the court’s primary field of view; conversely, excessively reducing light intensity or altering the light distribution to minimize glare will lead to a sharp drop in illuminance at the edges of the court, worsening uniformity and affecting players’ ability to accurately judge the speed and landing point of the ball. The core of high-performance futsal lighting lies in the synergistic balance between optical distribution design, optimized lighting pole/bracket layout and precise power settings, rather than relying on experience alone. Only through asymmetric light distribution, appropriate installation heights (such as the Hmin formula) and precise adjustment of aiming points can a competitive lighting environment be achieved that offers both a ‘comprehensive view’ and ‘comfortable vision’.
