Today, numerous nations place a higher priority on the growth of the sports industry. Good sports facilities are essential to the growth of sporting possibilities for everyone, from the youngest beginner to the world-class athlete. Sports lighting is just as crucial to the success of sports as traditional sporting arenas and equipment. To maintain the flow of the sport, sports lighting refers to the use of artificial lighting in stadiums to help stimulate natural lighting during the day. Even in challenging circumstances and in all kinds of weather, competitions and training scenarios in numerous sports require excellent illumination settings.
Lighting Needs For Sports
To create the best sports lights fixtures design, the designer must first comprehend and master the requirements for stadium lighting, which include adequate illumination, uniform illumination, no glare lighting, and suitable shadow effects.
1. Lighting Requirements
The major goal of sports lighting design is to satisfy the requirements of many sports, including hockey, football, and athletics. Football players move not only on the ground but also up to 10 to 30 meters above it. The majority of track and field events take place no higher than three meters from the ground.
The height of some sports, such as the javelin, discus, and hammer, can reach 20 meters. As a result, it is essential to maintain a specific brightness in all directions of a specific space height that satisfies the criteria for a consistent distribution of light on the ground. The brightness ratio between athletes, the location, and the audience must match certain standards for color TV live broadcasting, particularly HDTV broadcasting. Consistency is required in brightness, vertical illumination, and horizontal illumination.
2. Uniformity Of Illumination
The need for homogeneous lighting is required to ensure that TV cameras can record high-quality TV images. Additionally, uneven lighting will hurt spectators’ and athletes’ eyes simultaneously. The requirements for vertical illumination, illumination homogeneity, and illumination gradient are more stringent the faster the athletes move and the smaller the workout equipment.
3. Radiant Light And Glare
The brightness is determined by how bright it appears to the human eye and camera. As a result, the background and contrast of the image are crucial to its quality. For athletes’ and spectators’ optical comfort, brightness and glare are crucial. Given that a portion of the light should be focused on the stands to prevent having a background that is too dark. The bright stand background, not only lessens the glare from the audience on the opposite side of the screen but also improves the TV image.
In general, illumination intensity has a significant impact on glare. As long as the conflict between the spectators and the athlete is managed, the glare issue can be resolved. The designer is responsible for this coordination; therefore, when designing, it is important to take into account the flood light’s light distribution, the installation strategy, the height of the lamp suspension, and other elements.
4. Effect Of The Shadow
The quality of the TV image will be impacted by the extreme contrast between brightness and shadows, which makes it difficult to properly calibrate the TV camera. A dark environment will also make it harder to see. However, shadows play a crucial role in television transmission and viewership, particularly in football games with fast-paced, high-speed passing action. If there are shadow effects, the spectators can’t see the goal from the players.
Advice On Purchasing Sports Lights
The following are just a few of the numerous factors you should take into account when choosing led lighting fixtures for sporting events.
Examine The Beam Angle
The field’s distribution of light is controlled by the beam angle. The light homogeneity is poor when the angle is narrow. However, the light regularity is high if the angle is wide. For the stadium to be balanced, the lights you choose must have the correct beam angles.
Select Water-Resistant Lighting
Stadium lighting’s efficiency and durability are influenced by a variety of variables. Being waterproof is one consideration. You cannot ignore the issue because circumstances like humidity and wetness might have an impact on the lighting. Check the ratings to make sure they can function effectively in inclement weather.
Think About Heat Dissipation
Overheating can easily cause damage to the stadium lights. An effective system must have adequate ventilation. So, when selecting the lights, give aluminum-only models some thought. This is due to aluminum’s maximum conductivity rate being found in more modern alloys.
The glare rate is an important issue when it comes to sports lighting, even though most people do not take it into account when choosing stadium lights. This is so that football players and spectators won’t have eye strain from excessive light.
Select long-lasting lighting that won’t need to be replaced for several months or years. LED lighting, which normally has a rated life of 50,000 hours, is a suitable choice. Good LED lighting can go up to 11 years without needing to be replaced if used only 12 hours per day. This will enable you to cut expenditures while also guaranteeing that your lights are adequately illuminated without having to worry about them going out any time soon.
Color Rendering Index (CRI)
Color rendering index, often known as CRI, is a metric used to assess how accurately an object’s colors are rendered when lit by a light source. The index is scaled from 0 to 100, with 100 denoting perfect lighting of the subject beneath the light source. This indicates that the thing will seem as it would in direct sunlight. In essence, CRI provides a measurement of color accuracy, naturalness, vividness, preference, and hue discrimination. While high-quality incandescent bulbs and LED lights score close to 100 in CRI, low sodium vapor lamps are close to 0 CRI.
Parts Of Waterproof Lighting Is More Durable And Resistant To Rust
Waterproof LED lighting fixtures contain strong, rust-resistant parts in addition to being moisture-resistant. These also apply to any other accessories they could have, such as power supply, adapters, and lenses. These parts not only have a long lifespan but also require little upkeep. To keep them in good operating order, a checkup once or twice a year is sufficient.
Getting Uniform Lighting
When it comes to creating the ideal lighting in the stadium, uniformity is essential. This usually refers to how evenly the light is dispersed around the space. And the scale goes from 0 to 1. As a result, you should constantly make sure that all sports lights have the same lux level, say between 550 and 600, to ensure that the uniformity is close to 1, which is more in line with FIFA’s standard of 0.7.
Bringing The Temperature Down
A color temperature of more than 4000K is necessary for an average stadium. Therefore, working with 5000K to around 6000K is always safe. You can generate a cool white illumination in this manner that resembles natural daylight. Both the players and their supporters win from this.
In conclusion, the growth of the entire sports business depends on selecting the appropriate sports lighting fixtures.
