Design points of led stadium lighting

　　In addition  the stadium structure and materials, the stadium lighting has strict requirements on the floor materials, space height, luminosity, temperature, ventilation, and sound of the stadium. Among them, the lighting configuration is an extremely important part of the stadium design.

　　1. Facrs affecting stadium lighting

　　In order  ensure sufficient illumination in the gymnasium, the designer must consider the following facrs:

　　1) Illumination: In addition  ensuring the normal performance of the athletes and the accurate judgment of the referees, reasonable illuminance can also ensure that the audience can watch the game comfortably on site and in front of the TV. Different sports also require different illuminance. The illuminance required for sports events and commercial activities is also different.

　　2) Illumination uniformity: the ratio of the minimum illuminance value  the maximum illuminance value is the illuminance uniformity. Whether it is an indoor stadium or an open-air stadium, the lighting requirements are very high. Taking basketball games as an example, more lights tend  gather in the middle ground, but areas with o much light tend  produce glare, and the backboard area often The brightness of the light will be weak, ensuring the uniformity of the lighting of the overall venue, which plays a vital role in the performance of the athletes.

　　3) Glare: Glare refers  the visual conditions that cause visual discomfort and reduce the visibility of objects due  inappropriate brightness distribution or extreme brightness contrast in space or time in the field of view. There is a sense of light in the field of vision that the human eye cannot adapt , which will have a great impact on athletes, especially in ball games, where athletes cannot accurately determine the ball's drop point. In order  ensure uniform illuminance from all angles and prevent indoor glare, the elevation angle from the lowest point of the stadium’s light projection point  the lamps must be greater than 45°. Spectars cause direct sunlight, and current stadiums will use computers  calculate light projection points  ensure the uniformity and distribution of light. Indoor glare can also be caused by different floor materials or reflections on the water surface of swimming pools, so you can also install grilles or baffles for the lamps  reduce glare.

　　4) Lighting distribution: The stadium lighting is scattered, mainly divided in the watching area and the competition area. However, because the athlete's range of motion is not only a flat ground, vertical lighting also has a greater impact on athletes. Because while reasonably controlling the light illuminance, it is also necessary  reasonably plan the light distribution position  ensure the lighting requirements of the audirium on the premise of ensuring the athletes' competition.

　　5) Light source characteristics: The degree of light source rendering the color of the object is called color rendering, that is, the degree of fidelity of the color. The light source with high color rendering can reproduce the color better, and the color we see is closer  the natural primary color. , The light source with low color rendering has poor color reproduction, and the color deviation we see is also large. The light source in the stadium should ensure better color rendering, allowing athletes  have more accurate judgments.

　　2. Illumination requirements

　　Athletes, spectars, and venue phography have different illumination requirements. The vertical illuminance on the sideline of the athlete's playing field is used as the basic reference illuminance. The most basic illuminance can meet the athletes' competition requirements, the watching requirements of the on-site audience and the live broadcast requirements of the game. When the horizontal illuminance and vertical illuminance of the sports field are equal, the visual effect is the most comfortable. Even if they are not equal, the horizontal illuminance cannot exceed 2 times the vertical illuminance. Because the gymnasium is a three-dimensional space, the lighting of the indoor gymnasium must have high brightness and strong color contrast. The lighting control points calculated by the computer must have sufficient illuminance  ensure uniform illuminance, and the color temperature and color rendering must meet At the same time, the need for TV broadcasting is  control glare.

　　Three, lighting layout plan

　　1) In the lighting layout plan, the site plan is analyzed in detail, and the computer is used  analyze and calculate. Through reasonable lighting arrangement and different lighting modes, it can meet the illumination requirements of different levels of competitions and commercial activities.

　　2) The layout of the horse track. The design considers arranging 2 main horse lanes above the longitudinal competition field and 2 horse lanes above the longitudinal audirium. These 4 horse lanes are connected  each other, and lamps are installed on both sides of the horse lane.

　　3) Emergency lighting lighting arrangement. Due  a sudden power failure due  special reasons, the emergency light must be illuminated by the standby power supply  help the athletes and spectars in the stadium  evacuate.
