In the rapidly rising sports industry, the construction and upgrading of sports venues, as the core venues for sports activities, have attracted much
attention. As an important component of sports venue facilities, large space lighting technology is constantly innovating and developing to meet the
growing demands of sports events, training, and audience viewing.
The limitations of traditional large space lighting technology
In the past, sports venues mostly used traditional metal halide lamps as the main lighting source. Although these types of lighting fixtures can provide
a certain level of brightness, they have many drawbacks.
Firstly, the energy consumption is extremely high. During the emission process of metal halide lamps, a large amount of electrical energy is converted
into heat energy and wasted, which not only increases the operating costs of the venue but also goes against the current concept of energy conservation
and environmental protection.
Secondly, the service life is relatively short, and frequent replacement of lighting fixtures not only consumes manpower and material resources, but also
affects the normal use of the venue.
Thirdly, the lighting quality is difficult to meet the strict requirements of modern sports events. The color rendering index of traditional lighting fixtures
is relatively low, making it difficult to accurately reproduce the colors of objects, and prone to color distortion in television broadcasts.
Moreover, its glare control ability is poor, which can easily irritate the eyes of athletes and spectators, affecting the visual experience.
Innovative breakthroughs in modern large space lighting technology
The widespread application of LED lighting technology: With the advancement of technology, LED lighting technology has gradually become the
mainstream choice for large space lighting in sports venues. LED lighting fixtures have significant characteristics of high efficiency and energy saving.
Compared with traditional metal halide lamps, energy consumption can be reduced by 50% -70%, greatly reducing the electricity burden of venues.
At the same time, its service life has increased, reducing the frequency of lamp replacement and lowering maintenance costs.
In terms of lighting quality, LED lamps can achieve high color rendering index, generally reaching Ra ≥ 85, and even reaching Ra ≥ 95 in some high-end
products. They can accurately reproduce various colors in the venue, providing extremely realistic visual effects for athletes, viewers, and television
broadcasts. In addition, LED lighting fixtures have excellent dimming performance and can flexibly adjust the brightness and color temperature of
the lights according to different scene requirements, creating a suitable lighting atmosphere.
The development of intelligent lighting control systems: The emergence of intelligent lighting control systems has brought revolutionary changes to
the lighting of large spaces in sports venues. Through IoT technology, venue managers can remotely control and manage the entire lighting system
n a centralized manner. For example, in a basketball game, multiple lighting scene modes can be preset according to different stages of the game, such
as opening ceremony, game in progress, pause, overtime, etc. With just one click operation, it can be quickly switched to meet the lighting needs of
different scenes.
Moreover, the intelligent lighting system can automatically adjust the brightness of the lights based on factors such as personnel activity and ambient
light intensity in the venue. When there are few personnel in the venue, the brightness of the lights will be automatically reduced to achieve energy
conservation; When the ambient light is dim, automatically increase the brightness of the lights to ensure the lighting effect. Huaxia Beidou actively
invests in the research and development of intelligent lighting control systems, and its products can achieve linkage with other intelligent equipment
in the venue, such as sound systems, scoring systems, etc., further enhancing the intelligent management level of the venue.
The application of new optical designs and materials: In order to better control the propagation and distribution of light, improve illumination uniformity,
and reduce glare, new optical designs and materials are constantly emerging in the field of large space lighting. For example, some lighting fixtures adopt
a secondary optical lens design, which can more accurately control the illumination light, ensuring that the light evenly covers all corners of the sports
field and avoiding dark areas. At the same time, in terms of the material of the lamp housing, a new type of material with high transparency, UV resistance,
corrosion resistance and other characteristics has been selected, which not only improves the optical performance of the lamp, but also extends its service
life, making it suitable for the complex use environment of sports venues.
