Football Stadium LED Lights Buyer’s Guide

Sports are an important part of many cultures, and countless people in them are crazy about football. Football games at night without lights put players at risk of injury. Additionally, fans will not be able to watch games or find their way around the stadium.

In this buyer’s guide to football stadium LED lights, we will show you how to choose LEDs to light up outdoor games that meet FIFA World Cup, Olympic, Premier League and UEFA standards.

I.Brightness of Football Stadium

Lighting is divided into two parts, horizontal brightness and vertical brightness. The horizontal is for the light to cover the entire stadium, and the vertical is for player portraits. The lighting of the stadium should be 2000lux horizontally and 1500lux vertically. For these requirements, hundreds of sets of high power LED lights will be needed for a football stadium.

II.Uniformity of Illumination

UEFA also requires stadium lighting to have a uniformity of 0.5 to 0.7. This parameter is based on a scale of 0 to 1, indicating how evenly distributed the brightness is. This is an important consideration, as uneven lighting can irritate the eyes of both players and spectators. In fact, it is not an easy task to achieve high uniformity, because we can imagine the spot to be circular (or often rectangular), with overlapping and non-overlapping areas. One of the technologies employed by AIKO is the use of LED lights with a smaller beam angle and lower power. Asymmetrical design improves lighting distribution. We provide LED lights for international competitions such as Premier League and Olympic Games.

III.TV Broadcast Compatibility

Now is the new era of 4K TV broadcasting. Uniform and high-quality vertical brightness on the LED light allows for high standards of photo and video production. Therefore, we also strive to reduce the glare of the lights. Anti-glare optics in our LED lights won’t cause flickering and glare to players and spectators. This technology is achieved through special lens and coatings that suppress unwanted flare while maintaining brightness.

IV.Stadium Height

The height of the light is generally within 30-50 meters, we need high-quality LED lighting without too much loss of brightness. In fact, with today’s technology, light loss is sometimes unavoidable. No matter how precise your photometric design is, not all beams are 100% projected onto the football stadium, some (about 30%) are scattered around. How to solve this problem?

1.Use Better Optics

Choose high-quality LED chips and lenses, the beam will be more concentrated, reducing the loss of brightness. Then achieve a good balance with a comprehensive photometric design.

2.Increase the Number of Lights

Installing more LED lights on the stadium ceiling to prevent lumen loss is a relatively passive way. For example, if the theoretical (calculated) value is 10000 watts, we end up needing at least 12000 to 13000 watts for optimal results.

V .Save on Electricity Bills

Let’s calculate the total power required for the LED lights. A traditional football field is 105m*68m, and a lawn of 7140 square meters requires 7140*2000 lux=14,280,000 lumens. What does it mean? Since our LED lights have an efficacy of 140lm/W, the minimum wattage of the LEDs should be 14,280,000/140=102,000watts. This is the theoretical minimum we need because we also need to account for the light loss and fixture height mentioned above. Before doing computer lighting simulations, we would know that the required power is about 150,000 watts. Isn’t it incredible?

One more thing you need to know is that metal halide lamps have a luminous efficacy of about 70lm/W, so the required power is about 300,000 watts. Therefore, replacing metal halide lamps with LED lights can save a lot of energy and thus save on electricity bills.

VI.The problem of light pollution in the stadium

Too bright stadium lights will affect the quality of life of those around the stadium. The overhead lighting of sports stadiums must not cause light pollution. Spill light will seriously affect adjacent residential areas. One of the lighting requirements is that the ground brightness around the stadium should not exceed 25 to 30lux.

VII.Longer Service Life

By retrofitting metal halides to LED lights, the lifetime of the light was greatly increased to 80,000 hours. If left on for 8 hours a day, LED lights will last at least 25 years without significant loss in brightness. LEDs are also considered a durable light due to their solid state properties.

VIII.Good Cooling System

High durability requires football stadium LED lights to have a very good heat dissipation system. If heat continuously builds up around the LED chip, it will reduce brightness and lifespan. AIKO attaches great importance to this problem, we choose cold forged high-purity aluminum, coupled with the unique heat sink design, our products have good heat dissipation performance.

IX.Durability of LED lights

Replacing stadium lighting with metal halides will allow us to provide stronger materials for lights. That’s because our LED lights are made of polycarbonate and high-quality aluminum alloy. The material is corrosion resistant so it is unlikely to break in normal use. In addition, our products have IP66 waterproof certification. It can withstand heavy rain and general water splashes.

X.Warranty

From our experience, LED companies usually offer a 1 to 5 year warranty. Why not choose one with a longer warranty, so you can always get fast support from the company. AIKO Lighting provides a 7-10-year warranty, and the entire technical team will provide you with solutions.

1 by1 retrofit metal halide with LED

Metal halide lamps, often referred to as metal halide bulbs or fixtures, are a type of high-intensity discharge (HID) lamp that produces light by passing an electric arc through a mixture of gases and metal halide salts. These lamps are commonly used for indoor and outdoor lighting applications where high levels of brightness and color rendering are required. AIKO engineers are working now, and we pushed out ASP04 Series LED Sports Floodlights that can truly
