Do you notice the light pollution? How should we control it?

With the improvement of living standards, stadiums have become the main places for our leisure and entertainment, and the demand for stadium lighting has also increased significantly, but the light pollution of stadium lights is harmful to the lighting of sports venues, fitness personnel and residents. Both are pretty huge!

Stadium lighting basically requires reducing overflow light as much as possible, especially for stadiums surrounded by dense residential areas. Spill light, also known as spill light pollution, refers to the phenomenon that adjacent direct light or reflected light exceeds the scope of what should be illuminated, and illuminates other things. This requires the lighting fixtures to have precise light control capabilities. When the stadium spills light into the room through the window, it will affect people’s normal activities or rest. When the light interference is severe to a certain extent, even the use of curtains cannot guarantee the darkness of the indoor sleeping environment. Sleeping in a bright environment for a long time will prevent the brain nerves from getting a real rest and cause neurasthenia.

In addition, the glare on the court will also have a great impact on the personnel present. Hazardous manifestation 1: People who play ball only see a dazzling and dazzling light curtain, but they cannot see or clearly see spheres such as table tennis and badminton flying in the air. There is no way for the eyes to catch the sphere flying in the air, focus imaging and track the flight trajectory of the sphere, and swing the racket in the air.

Hazardous manifestation 2: When the glare energy of stadium lighting is large and the glare damage is serious. The dazzling light of venue lighting can also produce visual pain. The greater the glare energy, the greater the visual stinging. Hazardous performance 3: high color temperature and high energy glare, not only a strong stinging feeling to human eyes. Even if the eye field of vision leaves the light surface, there will still be a short-term visual black phenomenon. Moreover, the time for vision to return to normal visual sense is also related to high color temperature and high-energy glare intensity. The higher the color temperature and the stronger the glare energy, the longer the visual recovery time. Therefore, controlling glare is particularly important.

So what are the factors that affect glare? Unreasonable installation height of lamps and position of floodlights, unreasonable distance between lamp poles, unreasonable selection of light distribution of lamps, and no anti-glare device of lamps will cause serious glare. The stadium under the lights flickers, which brings great visual fatigue to the players.

Because of these considerations, our products are designed with light pollution in mind. There are strict controls on light pollution. Players can move freely on the court, and nearby residents can sleep peacefully.

After knowing the factors that affect light pollution, you can know how to solve these problems. When designing lamps, we must pay attention to the control of overflow light and glare. For the problem of glare, the main solutions are:

(1) Choose a smaller volume of high-strength light poles and control the material of the light poles;

(2) Make full use of the court trees and greenery;

(3) The position of the light pole should be combined with the shape of the stadium as much as possible;

(4) While using beautiful light poles, it is also necessary to use light sources with appropriate power and high-efficiency lamps. Using 1500W and 1800W lamps, the number of light poles and lamps is acceptable, the uniformity is very good, and the glare can be well controlled at the same time.

(5) The lamps and lanterns used in a well-lit stadium should consider installing anti-glare devices.

(6) Lamps with different light distributions should be selected for different areas, and lighting should be provided in a combination of wide and narrow light distributions. The more light distributions of lamps, the more flexible the design.

To sum up, we have learned about all aspects of overflow light and glare, and have a further understanding of the stadium lighting industry.
