3. LED Stadium Lights Recommendation
With the continuous development of society, the lighting standards and requirements of sports fields are also getting higher and higher. As the lighting method of future sports fields and arenas, LED technology has received extensive attention. LED Sports Lighting provides the uniform and wide coverage lighting needed in the air and on the ground on the sports field.
As sports become more and more popular among young people, portable stadium lights and LED floodlights for football pitches are also becoming more and more popular, and the demand has also increased greatly in recent years. This article will help you better understand and master the football field lighting guidelines.
Football LED lights have their own sports field lighting standardsand requirements. Different sports field lighting lux levels will have different lumen requirements.
Training entertainment 200lux
For a standard football field, it takes about 360,0000lm to illuminate a football field.
Amateur competition 300lx
A standard football field needs about 420,0000lm to illuminate a football field.
Professional competition 500lx
A standard football field needs about 600,0000lm to illuminate a football field.
1000lx for ordinary TV broadcasting, 1000lx for TV emergency
A standard football field needs about 126,000,00lm to illuminate a football field.
HDTV large international events 1400lx
An international standard football field needs about 309,000,00lm to light up a football field.

Motion lights create an illuminated surface by lighting the fixture, which we call a "beam angle". The angle is small and the illumination uniformity is low, which cannot meet the needs. But the larger the angle, the higher the regularity of the light, which will result in a waste of light. So the beam spread of the LED light should project the maximum amount of light onto the football field so that no hot spots are created.
The minimum installation height for all utility poles is 50 feet. The installation height can compensate for the extra lumen efficiency by increasing the height of the light pole. To reduce glare and make efficient use of the beam angle, the mounting height should be increased over time.
Football field lights can be installed at different heights, depending on the venue. The beam angle will vary with the height of the light pole. Some mounts go as low as 25 feet, but many of them are between 40 and 60 feet.
Uniformity is the ratio of the minimum light level to the average light level in a given area. It is the quality parameter of the overall illuminance distribution.
To ensure proper light uniformity is provided, it is important to compute the light uniformity in the space. How to accurately measure light uniformity, the following formula will help you.
U1 = E(lowest)/E(average)
U2 = E(min) / E(max)
U stands for uniformity and E for illuminance.
As can be seen from the above formula, the uniformity of light is basically the ratio of illuminance or lux levels. This uniformity ratio is useful because it allows you to determine how evenly the light will distribute light across the ground. If the difference between average and minimum lux is not high, the ratio will be high. It shows better light uniformity.
Color temperature is one of the important factors in sports lighting. Generally speaking, the standard of the sports field needs 4000-5500K. 5600K CCT is an NFL requirement as it is close to the sun temperature of 5778K.
During the day, the color of the sun's light changes over time. 40 minutes after the sun rises, the light color will gradually turn yellow, and the color temperature is around 3000K; at noon the sunlight color is white, and the CCT rises to 4800-5800K; if it is cloudy, it will be around 6500K at noon; when the sun is about to set, the color turns reddish , the color temperature drops to 2200K, which is consistent with the color temperature of candlelight. For outdoor sports facilities, 4000K or higher is generally required, and for indoor sports facilities, 4500K or lower is generally required.
The Color Rendering Index, also known as the CRI, which is a measurement of how color look under a light source when compare with the sunlight. The index is measured on a scale of 0-100, with a perfect 100 indicating that the color under the light source is the same as that under natural sunlight.
CRI represents the quality of light and the ability to reproduce the color of an object. The higher the CRI value, the better and more realistic the color of the object can be reproduced by the light source.
FIFA requirements stipulate that the lighting design standards must have good color, the CRI value of FIFA standard A and B must be greater than Ra80, and the CRI value of FIFA standard C and D must be greater than Ra70.
Sports field use LED lights of up to 600 to 1000 watt led stadium lights. Poor light leakage control affects the quality of life of nearby residents. Intense glare can obstruct the vision of road users and endanger the lives of pedestrians.
Glare is the loss of visual performance or discomfort that occurs when the intensity of light in the field of view is greater than what the eye is accustomed to. The perception of light in a visual field that the human eye cannot adapt to can cause disgust, discomfort, and even loss of vision. At the same time, glare is also one of the important causes of visual fatigue.
Uncomfortable glare on football pitches is caused by lamps that are too bright. To solve this problem, our football stadium lights are equipped with anti-glare and precise optics system that direct light to designated areas to reduce light loss. In addition to this, we can use stadium flood light with a smaller beam angle, thus making the light more concentrated.
What is light flicker? Light flickering is a rapid or rapid and repetitive change in the brightness of light over time - the light can appear wobbly and erratic. It is caused by changes in the voltage supplied to the light source or by fluctuations in the voltage of the power line itself.
This problem is particularly acute in football fields that host international, televised matches. In the sports lighting design, it is necessary to ensure that the football pitch led flood lights will not flicker in slow motion; otherwise, it will seriously affect the audience experience. The strobe light affects the judgment under playback, making your court look unprofessional.
