Sports lighting is incredibly significant in addition to supplying traditional sports arenas and sports equipment. Sports lighting is the use of artificial lighting in stadiums to assist simulate natural illumination throughout the day and assure the continuity of sports. Competitions and training scenarios in numerous sports require excellent illumination conditions, even in adverse weather circumstances.
Sports Lighting Specifications
To create a successful stadium lighting design, the designer must first understand and grasp the stadium lighting criteria, which include adequate illuminance and uniformity, no glare lighting, and acceptable shadow effects.
- Requirements For Illumination
Football movement occurs not just on the ground, but also 10-30 meters away from the ground. The majority of track and field contests are held at a height of roughly 3 meters above the earth. Javelin, discus, and hammer throwers may achieve heights exceeding 20 meters. As a result, maintaining a specified brightness in all directions of a certain space height and meeting the requirements for uniform light distribution on the ground is required. To satisfy the criteria of color TV live broadcasting, particularly HDTV broadcasting, the brightness ratio between athletes, the venue, and the audience must have a certain value. The horizontal, vertical, and brightness illuminances must all be uniform.
- Illumination Uniformity
The requirement for consistent illumination is required to guarantee that TV cameras can capture high-quality TV images.
Simultaneously, uneven lighting will cause athletes and spectators to experience visual discomfort.
The quicker the athletes move and the smaller the workout equipment, the more stringent the requirements for vertical lighting, homogeneity, and gradient.
- Glare And Brightness
The intensity of the perceived illumination is used as the brightness by both the camera and the human eye. As a result, the picture contrast and backdrop are the most significant for image quality. Brightness and glare are crucial factors in athletes’ and spectators’ visual comfort. To avoid a very gloomy background, a portion of the light should be directed to the stands. This not only eliminates glare from the audience on the opposite stand but also improves the TV image due to the bright stand background. In general, the brightness of lighting facilities is a major factor in the glare. The glaring issue may be resolved as long as the audience and athlete’s contradictions are harmonized. The designer is responsible for this coordination; for example, the light distribution of the floodlight, the installation plan, the height of the lamp suspension, and other elements should all be addressed while planning.
- The Use Of Shadows
The high contrast of brightness and shadows impedes proper TV camera adjustment, lowering the quality of the TV picture. Too much darkness reduces visual comfort. On the other hand, shadows are extremely important for television transmission and viewers, particularly in football games that involve fast-moving and high-speed passing elements. If there are shadow effects, the viewers will be unable to monitor the goal.
Suggestions For Purchasing Sports Lights
Examine The Beam Angle
The beam angle determines how light is scattered in the field. Light homogeneity is low when the angle is narrow. However, when the angle is large, the light regularity is great. As a result, the lights you choose must have suitable beam angles to establish equilibrium in the stadium.
Select Waterproof Lighting
Stadium lights’ efficacy and longevity are determined by a variety of factors. Being waterproof is one consideration. You cannot ignore the element since the lighting might be altered by variables such as humidity and dampness. Check the ratings to guarantee they will operate properly in adverse weather conditions.
Think About Heat Dissipation
Overheating may easily harm the stadium lights. A good ventilation system is essential. So, while shopping for lights, go for ones constructed of pure aluminum. This is because more sophisticated aluminum has the highest conductivity rate.
Glare Levels
Although most people do not consider the glare rate when selecting stadium lights, it is an important aspect of sports illumination. This is because excessive glare can cause optical discomfort to both football players and supporters.
Life Expectancy
Choose long-lasting lighting that will endure for months or years without needing to be replaced. LED lighting is a wonderful alternative because it has a rated life of 50,000 hours. Used only 12 hours a day, excellent LED lights will last up to 11 years without needing to be updated. This can help you save money while also guaranteeing that your lights are fully illuminated without concern of it going out anytime soon.
CRI
Color rendering index (CRI) is a measurement of the accuracy of an object’s colors when illuminated by a light source. The index is scaled from 0 to 100, with 100 representing the complete lighting of the item beneath the light source. This implies that the thing will seem exactly as it would in natural sunlight. CRI for low sodium vapor lamps is near to o, whereas CRI for high-quality incandescent bulbs and LED lights is close to 100.
Waterproof Lighting Has Stronger And Rust-Resistant Parts
Waterproof lighting fixtures feature components that are not only resistant to corrosion but also to the effects of moisture. In addition, they are resistant to moisture. These apply to their power supply, adapters, optics, and any other accessories they may have. These components are not only long-lasting but also low-maintenance. A once or twice-yearly checkup is all that is required to keep them in good operating order.
Achieving Lighting Consistency
When it comes to establishing great stadium lighting, uniformity is essential. This usually refers to the uniform dispersion of light across space. It also has a scale of 0 to 1. As a result, you should constantly keep the lux level on all best sports lights consistent, for example, between 550 and 600, so that the uniformity is close to 1, which is closer to the FIFA standard of 0.7 J. Obtaining a Cool Temperature
A color temperature of more than 4000K is required for an average stadium. As a result, working with 5000K to roughly 6000K is always safe. This will result in cool white lighting comparable to that of sunshine. This benefits both the athletes and their supporters.
Overall, selecting the correct sports lighting fixtures is critical to the growth of the overall sports business.
