What types of lighting fixtures are appropriate for sports stadiums? This requires us to return to the essence of sports lighting: functional requirements. To maximize viewership, sporting events are typically held at night, making many stadiums high-energy consumers. As a result, energy conservation becomes the primary goal for stadium lighting. When it comes to energy-saving products, LED lighting fixtures are the best option, saving 50% to 70% more energy than traditional lighting sources. Traditional lighting fixtures, such as high-power metal halide lamps, have an initial lumen output of 100 lm/W and a maintenance factor of 0.7–0.8. However, in most venues, after 2 to 3 years of use, the light decay exceeds 30%, including not only the attenuation of the light source itself but also factors such as oxidation of the fixture, poor sealing, pollution, and respiratory system issues, resulting in an actual lumen output of only 70 lm/W.
LED lighting fixtures, with their unique characteristics of low power consumption, adjustable color quality, flexible control, and instantaneous ignition, are well-suited for stadium lighting. For example, Tianxiang stadium lighting fixtures boast an efficiency of 110-130 lm/W and a constant illuminance output for 5000 hours, ensuring a constant and uniform illuminance level on the field. This avoids increasing the demand and cost of lighting equipment due to illuminance decay while simultaneously reducing power consumption.
1. Lighting fixtures professionally designed for LED characteristics, equipped with medium, narrow, and extra-narrow beam distributions;
2. Scientifically designed lenses and reflectors for effective light control;
3. Fully utilizing secondary reflections to reduce direct glare;
4. Scientifically determining the operating power of the LED light source to control its center luminous intensity;
5. Designing a suitable external glare controller to reduce glare and utilizing secondary reflections to improve luminous efficiency;
6. Controlling the projection angle and direction of individual LED beads.
Important sporting events are generally broadcast live. To obtain high-quality images, cameras naturally have much higher requirements for stadium lighting. For example, the stadium lighting for provincial games, national youth games, and domestic single-sport series requires a vertical illuminance of over 1000 lux in the direction of the main camera, while the illuminance of some commercially operated football clubs is often around 150 lux, which is several times higher.
Sports broadcasting also has strict standards for flicker in stadium lighting. For example, when HDTV broadcasts of international and major international competitions require ultra-high-speed camera work, the flicker ratio of the stadium lighting should not exceed 6%. Flicker is closely related to the constant current source. Metal halide lamps, due to their low starting voltage, operate at a high frequency, resulting in severe flicker. Tianxiang LED stadium lights, on the other hand, have “absolutely no flicker effect,” preventing eye fatigue and protecting eye health.
Sports lighting can demonstrate the image of a country, region, or city and is an important carrier of a country’s and region’s economic strength, technological level, and socio-cultural development. Tianxiang believes that the selection of stadium lighting fixtures should be done with caution. Stadium lighting must meet the functional needs of athletes, the needs of spectators to enjoy the competition, provide high-quality television images for television broadcasts, and provide a lighting environment for referees to make fair decisions while remaining safe, applicable, energy-efficient, environmentally friendly, economical, and technologically advanced.
