What are the lighting standards for outdoor stadiums?

There are different lighting standards for indoor and outdoor stadiums. Today AIKO would like to share with you some lighting standards for outdoor stadiums.

1.Spill Light

When designing some indoor stadium lighting, the designer will take into account the light reflection ability of the roof and make full use of the reflected light. Even in some indoor stadium design solutions, in order to make the light more uniform, the designer will let the light reach the ceiling, and then reflect the light to illuminate the stadium.

Outdoors, there are no ceilings and walls to reflect the light from the lamps, and it is easy to illuminate the surroundings of the stadium. This phenomenon of illuminating areas of a design that shouldn’t be lit is known as spill light. The generation of spill light means that the outdoor stadium lighting is not cost-effective enough, and part of the light is wasted. In addition to wasting resources, spill light can easily cause spill light interference. If the light shines into the sky, it will destroy the quiet night sky. If it shines on the surrounding residential areas, it will interfere with the normal rest of residents. When the light interference of the stadium is severe enough, even the use of curtains cannot guarantee the darkness of the indoor sleeping environment. Sleeping in a bright environment for a long time will make the brain nerves not really rest, causing neurasthenia and disrupting the production of melatonin (sleep hormone), and these effects are cumulative over time.

2.Arrangement of Light Poles

The installation methods of lamps for outdoor stadium lighting are mainly installed on horse tracks and light poles. The installation on the horse track mainly occurs in stadiums with auditoriums, and the lamps are installed on the horse track on the auditorium. Those without auditoriums are basically installed on light poles. The height of the light pole of the basketball court is basically between 8 and 15 meters; the height of the light pole of the volleyball court is basically between 8 and 15 meters; the height of the light pole of the five-a-side football field is basically between 8 and 15 meters; the height of the light poles of the seven-a-side football field is basically between 12 and 20 meters; the height of the light poles of the eleven-a-side football field is basically between 15 and 25 meters; the height of the light poles of the track and field is basically between 25 and 35 meters.

It can be seen that the outdoor stadium lighting pole is relatively high, so the outdoor stadium lighting should not be too heavy, the windward surface should not be too large, and the number of lamps hanging on one lamp pole should not be too much.

3.Demand for Lamps

The stadium lamps are installed outdoors, and it is inevitable that the wind, the sun and the rain will be a big test for the lamps. In the lighting industry, there is a clear testing standard for waterproof and dustproof, that is, the protection level IP. IP is the abbreviation of Ingress Protection Rating (or International Protection code), which defines the protection ability of an interface to liquid and solid particles. IP is followed by 2 digits, the first one represents the solid state protection level, ranging from 0 to 6, representing protection from large particles to dust, respectively; the second one represents the liquid protection level, ranging from 0 to 8, representing protection against from vertical water droplets to protection against bottom pressure. The higher the number, the better the ability.
