Outdoor Soccer Field Lighting Applications And Requirements

Outdoor Soccer Field Lighting Applications And Requirements

Soccer is known as the world's number one sport for its strong confrontation, versatile tactics and the large number of participants. There are 3.5 billion soccer fans in the world, including 200 million professional athletes, 260 million active amateur athletes, 2.8 billion inactive amateur athletes and 440 million non-participating spectators. In China, the viewership of soccer games broadcast is about 64 million; the viewership of various sports magazines, newspapers and books is about 37.5 million; the viewership of fan forums and online live streaming on the Internet is about 49.8 million.

The soccer field is the material basis and necessary conditions for the development of soccer, according to the "2022 China Football Market Analysis Report - Market Size and Future Prospects Research" data show that the country has about 105,300 soccer fields in 2020, campus soccer field accounted for 80%. Among them, 24,800 eleven-a-side soccer fields, accounting for 23.55%; 36,000 seven-a-side soccer fields, accounting for 34.18%; 44,400 five-a-side soccer fields, accounting for 42.16%, and 114 beach soccer fields, accounting for 0.11%.

As all we know, the outdoor soccer field standard size of 105m * 68m, and the different uses of the field correspond to the outdoor soccer field lighting standards are not the same.

According to the provisions of the national lighting standard GB153 document:

Please kindly check below outdoor soccer field lighting solutions applications and requirements

1. Outdoor soccer field site is large and has no support points, need to be arranged in the form of a combination of high light pole and centralized lamps and lanterns, with high requirements for lamp projection angle

The outdoor lighting distribution method generally adopts the four-corner pole type, in the form of a combination of centralized lamps and high poles arranged in the four corners of the football field, the height of the pole - generally, 35-60m, the specific height of the lowermost row of spotlights to the center of the soccer field and the ground angle should not be less than 25 ° to determine.

The position of the light pole also takes the triangle formed by the midpoint of the bottom line of the soccer field and the bottom line of the soccer field outward at an angle of 10° (15° for TV broadcast), the midpoint of the soccer field sideline and the sideline outward at an angle of 5° after the extension line of the two intersection points.

The illumination on the field is projected through different beam angle spotlights on the high bar, forming a suitable illumination distribution on the soccer field.

2. The light pole needs to consider the weighing capacity and windward area as well as anti-corrosion fall prevention and other accidents, to avoid unnecessary property damage caused by accidents, and even more to cause hidden danger to personal safety.

Safety is not a trivial matter, prevention is better than cure, Romanso for outdoor use light pole using hot dip galvanized steel pipe, steel chemical and electrochemical corrosion resistance is good, second only to titanium alloy; hot dip galvanized coating has the advantages of heat resistance, high temperature, low temperature, and even ultra-low temperature, long service life, etc., can effectively avoid the corrosion of light poles due to safety hazards. In addition, the lamps and lanterns use a double locking structure of the anti-fall device that can withstand 5KN of tension, high safety factor, and good reliability, and can effectively prevent the lamps and lanterns from falling off.

3. When selecting a light source, the following factors should be considered:

a. High efficiency and energy saving: LED working voltage is low, using DC drive mode, ultra-low power consumption, only a few degrees of electricity consumption for a thousand hours.

b. Timely start and stop: the light can be turned on or off in real time, without the need to warm up like metal halide lamps before opening.

c. Long life: LED lights without filament, glass bubble, not easy to break, service life of up to 50,000 hours.

d. Soft light: the light does not contain ultraviolet and infrared, no radiation

e. The color temperature and color rendering of the light source;

f. Utilization rate, lighting received on the field;

g. Annual usage time;

h. Initial investment and operating costs.

Halogen tungsten lamps, metal halide lamps, and high-pressure sodium lamps can be used for field lighting. Tungsten halide lamps are not suitable if high illumination is required. Unless it's used for a shorter period of time each year. If possible, the level of lighting installation can be improved to meet future colour requirements. For the requirement of the color TV broadcast, high pressure sodium lamp is not suitable for color TV broadcast, only a metal halide lamp can meet the requirement.

Romanso LED Sports Stadium Light, in addition to the above advantages, also have

l Stitching design, 240W~2000W composed of 1-6 lights;

l Light Efficiency: 150lm/W;

l High bright Luminleds/ CREE LEDs;

l Optics of 15º/30º/60º/60º×120º available on request;

l High-transmittance and anti-UV Frosted Polycarbonate lens;

l High reliable Meanwell/ Inventronics Driver;

l Excellent thermal management design;

l Die-casting aluminum with polyester powder coat finish;

l IP66/ IK10 rating for outdoor usage;

l Easy installation and low maintenance;

l Energy savings, no UV and IR radiations, emits low heat;

l Intelligent dimming system: 0-10V, DMX and DALI dimming modes;

l ETL/ cETL/ SAA/ FCC/ CE/ RoHS approval;

5 years warrant.

4. In the residential area around the course, the overflow light should be considered to avoid the spillover effect on the residential area caused by light scattering. The "Urban Environment Decorative Lighting Code" issued in 2004 stipulates that the overflow light shall not be fired into residents' Windows and interfere with residents' rest.

Meanwhile, the lighting quality of football fields mainly depends on the level of illumination, uniformity of illumination, and degree of glare control. Lighting required by athletes. The level is different from that of the audience, and for athletes, the required lighting level is relatively low, while the audience's purpose is to watch the game and illuminate. The requirement increases as the viewing distance increases.

In fact, the number of lighting fixtures is related to the number of spectators in the venue. Relatively speaking, the training ground only needs to install simple lighting fixtures. That's enough. And large stadiums need to be installed. Install more lighting fixtures to achieve high illumination and low glare by controlling the beam of light.

In addition to glare on athletes and spectators, lighting fixtures can also generate glare outside the field. But don't shine the lights on the football field, roads or residential areas around sports venues.

For spectators, the visibility of the athletes is related to vertical and horizontal lighting. Vertical lighting depends on the direction and position of the projection lamp. Recommended illuminance values refer to horizontal illuminance because it is easy to calculate and measure. The number of spectators varies greatly depending on the venue. The viewing distance is related to the capacity of the venue, so the illumination required by the venue increases with the increase of the stadium.
