Regarding sports lighting, LED lights have several advantages over traditional sports fixtures. They improve TV broadcasting and energy efficiency. Also, they last 25 times longer than standard metal halide fixtures.
Improves TV broadcasting
LEDs can be a great source of illumination for sports venues and stadiums. They can enhance the viewing experience for fans but reduce stadium operating costs. In recent years, stadiums have opted for high-efficiency LED sports lighting to improve the quality of TV broadcasting. For example, the new technology eliminates the typical flickering during slow-motion replays. In addition, LED systems can produce up to 20,000 frames per second compared to traditional lighting.
LEDs also offer flicker-free lighting. This allows television broadcasters to pan further across a field without being distracted by glare. It also improves picture quality and lighting uniformity.
LED stadium lighting can save stadium operators money and reduce maintenance costs. They also provide flexibility in operating controls. However, while LED technology is promising, some issues must be addressed before switching to LED.
Reduces glare
Using LED lights outdoors can create an uncomfortable glare problem. Using high-power LEDs combined with TIR lenses and reflectors create minimal light point sources. This glare is especially problematic if the light is directional.
To avoid this problem, stadiums should consider anti-glare LED lights. The proper placement and angle of LED lights will minimize glare. Moreover, anti-glare LED lights are energy-efficient and will create an ideal lighting environment for spectators and players.
LED lights are also very effective in helping players see well. The use of acrylic optical lenses helps reduce the impact of glare from LED lights on athletes. The beam angle is also critical when installing LED lights on a sports field. Some LED stadium lights require fifteen to sixty degrees of beam angles.
Increases energy efficiency
LEDs to light up sports venues are an ideal way to improve energy efficiency and reduce energy costs. Many countries offer funding to help clubs make these upgrades. In addition, new rules regarding light pollution have forced grounds to install LED lights to comply with environmental guidelines. LEDs also provide instantaneous strike times, meaning the lights are at full power when the game begins. In the event of a power failure, the lights will automatically come back on at full power.
Another advantage of LED lighting is the cost per lumen. LEDs are less expensive than incandescent bulbs, reducing the energy bill by as much as 90 percent. LED fixtures also last much longer than incandescent bulbs, making them a good investment. The Department of Energy estimates that by 2027, switching to LEDs will save 348 terawatt-hours of electricity, which is equivalent to the output of 44 large power plants. Additionally, switching to LED lighting can result in up to $30 billion in energy savings for businesses.
LED products are gaining in popularity, and the cost of LEDs is becoming more affordable. For example, the average price of an LED lamp is around USD 3 per watt. In the United States, LEDs have doubled in efficacy over the last decade, with one-fourth of lights achieving 120 lm/W or higher. This limit is expected to rise significantly over the next decade due to continuing product innovation.
It lasts 25x longer than metal halide.
LED sports lighting has many advantages over metal halide sports lights. It burns brighter and uses less energy to produce the same amount of light. In addition, LEDs last more than two times longer than metal halides.
One of their main benefits is that LEDs have a higher CRI than metal halides. This means that they can provide the same level of light without glare. LEDs also produce a steady, uniform light that responds instantly to changes in color.
While metal halide sports lighting can last up to 20,000 hours, it is less energy efficient than LED. For example, a 400-watt metal halide lamp produces up to 32,000 lumens initially, but it only produces half that amount after five thousand hours. Another disadvantage of metal halides is that they need to be operated longer than LEDs and don’t switch on and off on demand.
LEDs have a much narrower light spectrum, meaning they don’t waste energy producing non-light-related radiation. They also don’t produce heat, so most of their energy is converted to visible light. By contrast, metal halide lights give off appropriate amounts of IR and UV radiation, which is wasteful when used for regular illumination.
