In the field of outdoor sports, the lighting effect of outdoor stadium lights plays a decisive role in the performance of athletes, the viewing experience of spectators, and the smooth hosting of events. And all of this is closely related to a series of professional parameters of outdoor stadium lights.
1、 Luminous flux: illuminating the cornerstone of the stadium
Luminous flux: For outdoor sports fields, sufficient luminous flux is the foundation for achieving good lighting. Taking a standard football
field as an example, in order to meet the needs of competition and training, the total luminous flux of its lighting fixtures often needs to
reach hundreds of thousands of lumens. If the light flux is insufficient, the court will appear dim, making it difficult for athletes to see the
trajectory of the ball and the positions of teammates and opponents. This not only affects the quality of the game, but may also increase the risk of injury.
2、 Illumination: Meet the needs of different competitions
Illumination: Different types of sports events have significantly different requirements for illumination. The illumination standard for ordinary
training venues is usually between 200-500 lx, while FIFA requires the illumination of World Cup football venues to reach 3000-5000 lx. Reasonable
illumination distribution can avoid uneven brightness on the field, allowing athletes to have a good visual environment and make accurate
judgments and reactions.
3、 Color temperature: Creating a comfortable visual environment
Color temperature: In outdoor stadium lighting, a color temperature of 5000K-6000K is more suitable. This range is close to natural light
and can effectively reduce glare, making it less likely for athletes and spectators to get tired when watching games for a long time. At the
same time, a suitable color temperature helps to improve color reproduction, allowing athletes' clothing, court colors, and other colors to
present the most realistic state.
4、 Color rendering index: restore true colors
Color rendering index: The color rendering index (Ra) is used to measure the degree to which a light source presents the color of an object.
The higher the value, the closer the color of the object under that light source is to the color under natural light. For outdoor stadium lighting,
a color rendering index greater than 80 is a basic requirement. High color rendering index lamps allow athletes to clearly distinguish the color,
trajectory, and positions of teammates and opponents of the ball, enhancing the safety and viewing experience of the game.
5、 Energy Efficiency Ratio: A New Trend in Energy Conservation and Environmental Protection
In the current trend of advocating energy conservation and environmental protection, the energy efficiency ratio of outdoor stadium lights
is receiving increasing attention. The higher the energy efficiency ratio, the more luminous flux can be generated when consuming the same
amount of electricity. At present, the energy efficiency ratio of advanced outdoor stadium lights on the market can reach over 100 lm/W. The
use of high-efficiency lamps not only reduces operating costs, but also conforms to the concept of sustainable development.
Among numerous outdoor stadium lighting brands, Huaxia Beidouxing stands out with its strong technological strength. The maximum luminous
flux of a single outdoor stadium light can reach 180000 lm, providing sufficient illumination for large areas of the stadium; In terms of illumination
control, it can accurately match the needs of different events, whether it is daily training or professional events, and can evenly distribute the
illumination within a reasonable range. The color temperature is strictly controlled at around 5500K to reduce glare interference and prevent visual
fatigue during prolonged viewing; The color rendering index has reached Ra ≥ 90, far exceeding the industry's basic requirements, accurately
reproducing the colors of sports scenes.
In addition, the energy efficiency ratio of some lighting fixtures on Huaxia Beidou Star has exceeded 120 lm/W, significantly reducing energy
consumption while ensuring lighting effects, practicing the concept of green lighting, and becoming a reliable choice for many outdoor stadium lighting.
