Lighting football game stadiums fields ought to be administrated in accordance with established rules. There square measure variety of standards in sports coverage – they regulate the necessities for the coverage of the football game fields.
In Europe, on the idea of the commonplace linear unit 12193: 1999 for the various categories of games square measure regulated by the varied levels of illumination football game fields. once lighted football game stadiums used mast, linear or mixed systems.
Mast systems are widely spread, mainly in embodiment 4 using supports mounted on the corners of the pitch. Practice shows that in this case the basic lighting requirements can be implemented, however, the system has inherent disadvantages: because limit glare of spotlights require high masts. Depending on the location of their height, they can reach 80 meters or more, which significantly increases the cost of construction. The disadvantage of the system is the presence of 4 shadows to illuminate objects (athletes, sports equipment). Therefore, a 4-mast lighting system for use in conjunction with groups of floodlights mounted on the visor, supports other building elements and serve to improve the quality indicators of the rugby field lighting.
Size of Rugby Field
In this case study, we assume the size of full field is 120 * 70 meters, though the actual dimension may vary a little bit. we offer the high mast lights for rugby field, such as 4 poles and 6 poles.
Brightness and uniformity
When it comes to power selection on the rugby stadium lights, we can make a reference to the guideline imposed by RFU, which states that for the recreational and general commercial use, the lux requirement is about 250 to 300 lux. What does it mean? We may have the following estimation.
The total lumen needed = 250 * 120 * 70 = 2,100,000 lumens. For our LED rugby league field lighting, it is equivalent to 15000 Watt. Then, the lighting uniformity is about 0.6, which is a normal value for sports field. How to achieve such the value? Our engineers will make use of lighting design software called DIALux to simulate the illuminance on the ground. By choosing different individual power and beam angle of LED lights, we can get the best rugby field lights having the high performance. Nonetheless, the lux can raise to 500 or more for the professional matches.
Why using LED flood lights for rugby fields?
LED has exceptionally long-life span of 80,000 hours. In 2018, we improve the LED chips arrangement and heat dissipation system, therefore, the heat accumulation inside the lights is reduced by 30% more than the past design. Heat is a paramount factor for the working time of luminary because poor thermal condition declines its performance.
LED high-mast lights are much durable than metal halide, HID or HPS lamps. For the rugby stadium lights, they may encounter many adverse weathers. Since our sports field lights obtain IP66 waterproof cert, they function normally under the stormy rains. Besides, the solid-state LED is able to light the fields under the extreme low temperature of -40°C. And thus, our luminaires are so versatile that can fit for almost all venues.
illuminance levels of Rugby pitch lighting
Some of our solutions for each of these key levels can be downloaded from our Standard schemes section at the left, however different options are available to suit your needs, we can even create systems which will allow you to upgrade to the next level at a future date.
European standards, EN 12193:2007, set illuminance levels at 500lux for class I, 200lux for class II and 75lux for class III. The RFU however publish their own standards for class I and II as detailed below:
