Under the background of the rising concern of global energy shortage, saving energy is a very important issue that we will face in the future. In stadium lighting field, the application of LED stadium lights is attracting people’s eyes. LED outside lights, as new and green light source, must be a tendency in the future development. In the 21st century, sports lighting field will enter into a new-style lighting source era represented by LED stadium lighting fixtures, or LED athletic lighting fixtures. They all belong to LED field lighting. That’s why nowadays so many stadium lighting companies or led stadium lighting manufacturers are arising.
Modern sports activities are enhanced with the development of human society. Sports activities can are delimited by the boundaries of stadium construction. The designing features of stadium lighting are: big space, long distance and high illuminance technology of light shooting ability. So LED athletic field lighting usually adopts professional LED lighting fixtures and led projection lights or led projectors with high efficiency and long life span.
The key point of LED football lighting design is the inside field lighting, that is to illuminate a match. The field lighting inside the stadium is a design of strong functionality, high technology and great difficulty. It has to meet the requirements of all kinds of sports events, make for athletes to exert their technical merits and referees to make right judgments, as spectators also have good watching experience from all positions and locations. Professional stadium lighting design should pay close attention to color television’s live broadcast. To guarantee lively, clear and colorful retransmitted images, vertical illuminance, illuminance uniformity and stereoscopic sensation, color temperature and CRI of light source are specifically required. Whether or not the stadium lighting design can meet the requirements of illuminance standards and lighting quality, is one of the main symbols of evaluating a stadium.
What Lighting Fixtures are Used in Stadium Lighting?
LED flood light is a kind of light fixture whose illuminance on the assigned lighting surface is higher than the environment, also called LED outdoor spotlights. Generally, LED outdoor flood light bulbs can shoot every direction and have the structure of being immune from climate conditions. They are mainly applied to large-area working places, outlines of architecture, sports fields, flyovers, monuments.
and parks. Therefore, almost all outdoor large-scale used lighting fixtures can be viewed as flood lights. Light shooting angles of LED flood lights outdoor used can be wide and narrow. The range is from 15° to 120°. The narrow ones are called LED projectors.
LED flood lights can be installed not only individually, but also intensively with many pieces on top of poles that are more than 20 to 40 meters high, thus forming high-pole lighting equipment. The biggest advantage of this kind of equipment is the strong lighting function. Besides, it has beautiful model effect and spread. It can be intensively maintained. The poles and area size can be reduced. When lights shoot from high places, the spatial brightness of environment is widely covered, and the light scope is large. These make people feel as if they were watching a match almost during daytime. Consequently, LED flood lights have high lighting quality and visual effects.
To meet the standard safety requirements when working outside, LED flood lights should have housing protection level IP65 or IP66. To improve luminaries’ durable performance and decrease its maintenance work, installers attach more and more importance to developing closed flood lights with high one-time investment costs. The housing protection level is IP65 or IP66.
To decrease light fixtures’ weight and metal materials’ wastage, outdoor LED flood light fixtures are being developed towards plastic housing with high temperature resistance, high mechanical intensity and ageing resistance.
The choice on light source is vitally important for stadium lighting projects. Stadiums with high installation of lights should adopt high efficiency LED flood lights, with powerful throw ability and advanced optics. Stadiums with low installation, can adopt lower optical efficiency LED flood lights, if the lumen is higher. Special luminaires can be used in special places, like explosion-proof ones. Light source efficiency should be adapted to sports field size, installation position and height. Outdoor stadiums are supposed to use high and medium power LED flood lights and guarantee light source to work without a break, so that they can be quickly started.
Light source should have suitable color temperature, good color rendering index, high light efficiency, long life span and stable photoelectrical characteristics. Glare has direct relation to illumination styles, installation height, angles and light power. Places with high requirements of glare are recommended to be equipped with highly suspended LED flood lights or highly adjust angles to decrease glare.
There are three big reasons why the most developed sports fields choose LED lighting system. The first one is that LED lighting and control can improve TV broadcast. The second one is that LED lighting system can make spectators have better watching experience in matches. And the final one comes from that advanced lighting system helps to decrease operation costs and increase energy efficiency.
