With the passage of time, the lighting standards and requirements of sports fields have become higher and higher. Used as the lighting way of sports fields and arenas in the future, LED technology has attracted widespread attention. Led sports light offer the uniform lighting required for air and ground on the sports field. The following trend is that the construction of sports fields is becoming more and more popular, and the demand has also increased greatly in recent years. The guide is very important to how to illuminate and plan optimal lighting.
Sport light can be used for various sports fields, such as the football field, baseball field, etc. Here introduce the standard of football sport field. Because football is the most important sport and one of the popular competitions.
Compared with decorative lighting, its most direct goal of led football field light is to provide basic lighting for athletes, audiences, coaches, spectators, and cameras and video cameras. The light seeks to be as close to natural light as possible and is an auxiliary existence for sports. But the purpose of decorative lighting is to highlight the illuminated object or the light itself and make it more noticeable. For example, in a light show, the light is the protagonist.
The lighting standard of a football field can be as below:

The lighting standard of the football field has always been formulated by developed countries in football, and the levels and systems of football games in these countries are very complete. Hishine has the complete Research & Development team (R&D team) and mature R&D capabilities, therefore, led sports light can be customized according to your need.
LED provides a super lighting experience with athletes and audiences. The installing way to led sport light in different places are different. According to the usage of function, the standards of led football field light should be divided into seven levels:
Level 1: Training and entertainment competition--200lux
Level 2: League competition--500lux
Level 3: Professional competition--750lux
Level 4: General TV competition--1000lux
Level 5: Large International TV competition--1400lux
Level 6: TV emergency--750luxCorrelated Color Temperature (CCT)
Color temperature is one of the important points in sports lighting. In general, 4000-5500K is required for the standard of the sports field. 5600K CCT is the requirement of the NFL, because it is closed to the sun’s temperature of 5778K.
During the day, the light color of the sun will change with time. The light color will be yellower when the sun is rising 40 minutes, the color temperature is around 3000K; the light color is white when the sun at noon, CCT rising to 4800-5800K, and it is around 6500K at noon if it is cloudy days; the light color is reddish when the sun is going to set, the color temperature reduces to 2200K, and it will be the same as the color temperature of candlelight. For outdoor sports facilities, 4000K or higher is generally required, especially at dusk to match the daylight. For indoor sports facilities, it usually requires 4500K or lower.
Only for outdoor sports fields, it can be divided into kinds of fields, such as the football field, basketball field, outdoor stadium field, baseball field, tennis court, etc. And sometimes the fields will not have detailed usage, thus it needs a general standard to ensure the illumination of the sports field.
The general standard can be as below:

The lighting standards of current sports field include:
-NFL: 250 foot candles
-Collegiate-level footbal: 150 foot candles
-High school football fields: 50 foot candles
The pole quantities of led football field light are recommended that: four and six. The four pole rule is that: two poles are located on each side, and not closed to the sideline. A six pole rule is that: three poles are located on each sides and closed to the sidelines.
The sports light will form a illuminated surface through lighting up the lamp, and we called it “beam angle”. If the angle is small, the light uniformity is low and can’t satisfy the need. However, if the angle is larger, the light regularity is higher and cause the waste of lighting. The beam diffusion of led light should project the maximum amount of light onto the football field without generating hot spots. Beam angle must be wide enough to distribute aiming point with an adjacent overlapping.
The minimum installing height of all poles is 50 feet. The installing height can make up extra lumen efficacy by increasing the pole’s height. In order to reduce glare and efficiently use the beam angle of light, the installing height should be increasing at anytime.
The book “Sports and Recreational Area Lighting” had been published by the illuminating Engineering Society. It is to emphasize the best level of sports lighting. On this book, the best standards for athletes and spectators have been analyzed in all aspects, and the solutions related to LED, metal halide, fluorescent and plasma light are both discussed.
The led’s energy efficiency is highlighted especially by IES, even thought its upfront charge is very expensive. The control of advanced beam angle and less light spillage and pollution than other suppliers are the advantages of LED.
LED stadium lighting replaces traditional stadium lights with the characteristics of safety, low power consumption and bright light. It can also be widely used in sports fields, basketball courts, football fields, tennis courts, golf courses, badminton courts, rugby fields, etc.
LED Stadium Light
It has a brightness of up to 170lm/W, which brings high lumens and saves at least 50% of energy consumption. The product has passed UL, DLC, CB, SAA, IK10, and IP67 certification, which can be very dustproof and waterproof. It is perfect for outdoor work.
Led High Mast Light
Leading the lighting of all high pole lights in the industry, with a lumen of up to 160lm/w, emits uniform and soft light, good color rendering, and excellent lighting effects. In addition, there are high quality, energy saving, long service life, etc. advantage.
LED Flood Light
The adjustable mounting bracket allows you to accurately focus the light output, reduce light loss and glare, and bring the best lighting experience. After professional quality inspection, while being durable, we are also committed to a warranty of 3-5 years. You provide guaranteed after-sales service.
