The needs of stadium lighting and the key steps of lighting design can be summarized as follows:

Lighting demand
Light intensity: Sports venues need to provide sufficient light intensity to ensure that spectators and athletes can clearly see the playing field. For example, the light intensity required for football and basketball courts is between 500 and 1000 LUX, while the light intensity required for track and field is between 300 and 700 lux.
Lighting uniformity: Stadium lighting also needs to ensure the uniformity of lighting to avoid uneven lighting. In general, the lighting uniformity of the stadium is required to be above 0.7 to ensure that the lighting effect is consistent throughout the site.
Color reducibility: Stadium lighting requires to provide good color reducibility, so that spectators and athletes can truly feel the color of the game. Usually, the color reducibility of sports venues requires more than 80.
Key steps in lighting design
Analysis of venue functions and layout: Before lighting design, it is first necessary to analyze the function of the stadium, the layout and size of the venue, in order to develop a suitable lighting scheme according to actual needs.
Determine the installation position of the lamp: the installation position of the lamp is the basis of illumination calculation. Most of the stadium lighting fixtures will be installed on the bridleway, so it is necessary to design the lighting position according to the location of the bridleway.
Lamp selection: According to the space size of the stadium, the installation height of the lamp and the projection Angle and other factors, choose the appropriate lamp type, power and light distribution. For example, different positions such as audience seats, rostrums, scoreboards, and billboards may require lamps with different light distribution.
Camera position determination: According to different site locations, determine the position of the main camera and the secondary camera in accordance with the national standard specifications to ensure the quality of the game broadcast.
Lighting mode analysis: Different lighting modes are analyzed according to the functional level of the stadium (such as whether or not it is televised) to meet the needs of different competitions and events.
Lighting design key points
Illuminance level: Determine the appropriate illuminance level for different sports and competition levels. International competitions usually require a higher level of illumination.
Uniformity: Ensure a uniform distribution of horizontal and vertical illuminance to avoid areas that are too bright or too dark.
Glare control: Prevent discomfort for athletes and spectators by controlling glare with appropriate luminaire covers, positioning and Angle adjustments.
Lighting arrangement: According to the size and shape of the stadium, choose the appropriate lighting equipment (such as floodlights, downlights and lamp belts, etc.), and achieve uniform lighting effects through reasonable arrangement.
Control system: Consider the control system of the stadium lighting, so as to flexibly adjust the brightness and color of the light to meet the needs of different competitions and activities.
By following the above steps and key points, you can ensure that the lighting design of the stadium meets the needs of the competition and event, while providing a comfortable and safe visual environment.
