Analysis of intelligent lighting solutions for large stadiums

Lighting is one of the important links to fully reflect the function of the stadium, the focus of the stadium lighting is the stadium lighting, that is, the competition lighting; Secondly, general lighting, audience lighting, emergency lighting, site lighting, building facade lighting and road lighting systems are all important components of stadium lighting; How to meet the scene lighting of various competition venues, unified treatment of each part of the lighting system, so that the color temperature, illuminance, glare, color rendering index meet the prescribed standards; This is not only the choice of lamps and light sources, but also depends on the choice of control system and how to arrange the cooperation of various parts of the lighting, accurately express the requirements of various competitions for lighting, the choice of intelligent lighting management system is a necessary choice for modern comprehensive functional sports venues.

Second, demand analysis

1, modern stadium lighting characteristics

Modern multi-functional sports venues can be divided into two areas according to functional areas, namely, the main arena and the auxiliary area. All auxiliary areas can be subdivided into auditorium, restaurant, bar, cafe, meeting room and so on. Modern sports venues have the following basic requirements for lighting:

① Athletes and referees: can clearly see any activities in the competition venue, to give the best performance.

Spectators: Watch the game in comfort, while being able to clearly see the surrounding environment, especially safety issues during entry, viewing and exit.

③ Television, film and news workers: close-up shots of the game, athletes, spectators, scoreboards… And so on, can ingest excellent results.

For the lighting of the main stadium, the lighting brightness is not only required to be stable and reliable, to meet the visual requirements of the athletes during the competition, but also to meet the lighting requirements of color television broadcasting and photography. Generally, the color rendering index of the main stadium lighting Ra should be greater than 70, the color temperature should be 3000-7000K, the brightness should be 300-1500lux, and the illumination can be reduced to 750Lux in general competition and training.

The lighting of the main stadium can generally be based on gold halide lamps, mixed tungsten iodide lamps, PAR lamps as a combination to meet the requirements of illumination. Due to the large power of the gold halide lamp (250W-2000W), its starting current is 1.5 times larger than the normal working current, the starting time of the lamp is as long as 4-10 minutes, and the restart time is longer, about 10-15 minutes, which requires the necessary control of the starting of the gold halide lamp.

In the same venue, different sports competitions have different requirements on the lighting mode of the venue. Even if the same competition is in different time periods, such as the preparation of the competition, the start of the official competition, the rest of the field, and the audience, the lighting control of the competition venue needs to adapt to different lighting modes. It is difficult to realize various control requirements with general control devices.

For the various functional places of the auxiliary area, the lighting effect plays a very key role in the entire environment, because this lighting design is particularly important. Usually use a variety of light sources, style and rich layers, through dimming and scene pre-setting functions to create a variety of lighting effects, transform different light space, giving people a comfortable and perfect visual enjoyment.
