The smooth development of sports events relies on the support of numerous factors, and the lighting in the sports arena is like a cornerstone, steadily supporting the operation of the entire event. It has an immeasurable impact on the performance of athletes, the viewing experience of spectators, and the fair and just conduct of competitions.
From the perspective of athletes, appropriate stadium lighting is one of the key factors for them to perform at their best level. Taking volleyball as an example, athletes need to accurately determine the flight trajectory, speed, and landing point of the volleyball in an instant, in order to make accurate hitting movements. This requires the lighting system to provide sufficient and uniform light, reducing visual errors. According to professional standards, the average horizontal illumination of volleyball competition venues should reach 1000 lx or above, and the uniformity of illumination should not be less than 0.6. Such lighting conditions can ensure that athletes can clearly see the movement status of the ball no matter where they are on the field, better utilize their technical level, and reduce the occurrence of mistakes.
Meanwhile, good lighting can also enhance the comfort and focus of athletes, allowing them to fully immerse themselves in intense competitions.
In some competitive sports such as basketball games, sufficient lighting can allow athletes to observe the movements of opponents and teammates
more clearly, predict the situation, avoid dangerous movements caused by unclear vision, and ensure the safety of themselves and other athletes. Huaxia
Beidou Star is well aware of the demand of athletes for high-quality lighting. Its lighting products provide clear and comfortable visual environments for
athletes in many sports venues, helping them to sweat on the field to the fullest.
For the audience, the lighting in the sports arena directly affects their viewing experience. A wonderful sports event not only requires outstanding
performances from athletes, but also requires the audience to be able to clearly appreciate every exciting moment of the game. High quality lighting
can make the audience feel as if they are there, experiencing the tension and excitement of the competition. In a football match, bright, uniform, and
glare free lighting can allow the audience to clearly see the players' running, passing, shooting, and other movements, as well as the tacit cooperation
between teams. When the audience can clearly see the athletes' superb skills and passionate performances, their immersion and joy in watching the
game will also be greatly enhanced. In addition, lighting can create different atmospheres by adjusting color temperature and color. In the final stage
of large-scale sports events, warm toned lighting can create a lively and tense atmosphere, stimulate the enthusiasm of the audience, and make them
more engaged in the game, creating a strong emotional resonance with the on-site atmosphere. The lighting system of Huaxia Beidou Star has also
shown excellent performance in creating a viewing atmosphere, bringing better viewing enjoyment to the audience.
From the perspective of fairness and justice in the competition itself, the lighting in the sports arena plays a crucial role. In sports events, referees need
to make fair judgments based on accurate visual information. Taking track and field competitions as an example, in sprint events, referees need to
accurately determine who will hit the line first at the moment when the athlete crosses the line. This requires lighting to clearly illuminate the finish
line area to avoid misjudgment caused by lighting issues. According to the lighting standards for track and field events, the vertical illumination in
the finish line area should be above 1500 lx, and the uniformity of illumination should meet certain requirements. Only under such lighting conditions
can the referee make accurate and fair decisions, ensuring the fairness of the game.
In order to meet the strict requirements of sports events for stadium lighting, careful design and control are needed in multiple aspects. In terms of
illumination requirements, different types of sports events have different standards. For international competitions broadcasted on television, the
horizontal illumination of the venue usually needs to reach 1500 lx or more, and the vertical illumination needs to reach 1000 lx or more, in order
to meet the shooting requirements of high-definition cameras and provide clear and high-quality event images for global audiences.
In terms of illumination uniformity, the ratio of the minimum to maximum horizontal illumination of the sports field should not be less than 0.5, the
ratio of the minimum to maximum vertical illumination in the main camera direction should not be less than 0.4, and the ratio of the average vertical
illumination to the average horizontal illumination should not be less than 0.25. Good uniformity can avoid uneven lighting on the field, reduce visual
fatigue for athletes and spectators, and ensure fairness and viewing of the competition. The color rendering index is equally important. For domestic
and international competitions broadcasted on television, the color rendering index Ra of the light source is ≥ 80, and for competitions broadcasted
on high-definition television, the color rendering index Ra is ≥ 90. High color rendering light sources can realistically present the colors of athletes'
clothing, venue facilities, and audience skin, making the entire competition scene more vivid and realistic, enhancing the visual experience.
In addition, glare control is also a critical step. The glare index GR of indoor sports venues is ≤ 40, and the glare index GR of outdoor sports venues
is ≤ 50. By selecting appropriate lighting fixtures, controlling their shading and pitch angles reasonably, and optimizing their layout, glare can be
effectively reduced, creating a comfortable visual environment for athletes and spectators.
The selection and arrangement of lighting fixtures are crucial in achieving high-quality stadium lighting. Choose appropriate lighting fixtures based on the type, spatial structure, and lighting requirements of the sports arena. For sports venues with large spaces and high heights, high-power floodlights or LED lights can be used to achieve large-area and high brightness lighting through reasonable arrangement of lighting fixtures. In terms of lighting arrangement, methods such as setting up lamp posts around the venue and building a lighting runway above the venue can be used to ensure that the light evenly covers the entire venue. At the same time, attention should be paid to the installation height, angle, and spacing of the lighting fixtures to avoid blind spots and glare problems.
