The LED technology in the Stadium Now

What happened in lighting engineering for the last 5 to 7 years is a technological revolution. In place of traditional light sources came innovative LED technology. First of all, they occupied the niche of office and commercial lighting, where not so much light was needed. Then they confidently began to enter the industrial and street lighting manufacturers have learned how to make relatively compact and reliable lamps with large luminous flux.

Powerful and affordable football stadium lights for sports lighting to the requirements of HDTV appeared only now. And it is very important to choose exceptionally high-quality equipment so that it does not fail at the most crucial moment.

Now the technology has allowed creating high-quality LED lamps for sports lighting with the desired luminous flux, reliable in operation and adequate in cost. It really made a revolution in the coverage of large open spaces, including sports.

The main advantage of high-quality LED spotlights over traditional ones, in addition to long service life, is instant switching on and off. This allows you to implement any dynamic scenarios in the lighting up to light shows.

Regulatory requirements

The quantitative and qualitative parameters of lighting regulate such documents as the Standards of electric lighting of sports facilities, Codes of Practice on the design of various sports facilities, European standards for the coverage of sports facilities, Recommendations of the International Commission on Illumination.

For example, FIFA, UEFA, and the IAAF have developed special recommendations for creating lighting installations for stadiums for different levels of competition. The standards for lighting regulate the levels of horizontal and vertical for competitions with TV broadcasts of illumination, the uniformity of its distribution, the level of glare and colour characteristics of light sources.

Colour rendering index

To obtain high-quality colour television images in HDTV format, lighting devices with a temperature of 5600 K and more with a colour rendering index are increasingly used. For sports facilities designed for competitions without television broadcasts and training sessions, the colour transmission properties of light sources are not critical and here, as a rule, lamps with a colour rendering index of 65 are used.

Recently, LED lamps, whose small dimensions make it possible to most efficiently distribute the luminous flux, are increasingly being used to illuminate sports facilities with television broadcasts. Very good colour quality and the ability to instantly enable them to be used in top-level lighting installations for international and national TV-shooting competitions.

The main criteria for the selection of equipment for the sports lighting system are the lighting parameters, performance, economic indicators and design features that allow the most efficient solution of the lighting problem. Depending on the normalized level of illumination and the distance to the illuminated surface, lighting devices of different light distribution and the different power of the light source are used.

For the rational use of the lighting installation of a large object, at least four switching modes are usually provided: for international matches with TV broadcasts for conducting continuous television broadcasting in case of emergency power supply disconnection for non-televised competitions and training sessions.
