The calculation of illuminance (lux) of outdoor tennis courts involves a number of factors, and the following are the calculation and consideration points summarized based on the information in the reference article:
Illuminance standard:
Amateur competition (training) : 150lx-300lx
General race: 300lx-500lx
Official competition: 500lx-750lx (up to 1500lx)
Audience illumination:
The illumination standard for the auditorium is usually between 30lx-100lx (80 lux-300 lux for the room).
Lighting arrangement:
Outdoor tennis court lamps should be set on both sides of the fence fence above the ground height of 6 meters, lights from both sides of the court scene evenly illuminated.
The standard tennis court lighting arrangement may include 8 lamps, the height of the pole is 7 meters, the power of the light source is 400w, and the average illuminance can reach more than 400lx.
Light pole height and arrangement:
The height of the light pole of a single outdoor tennis court shall ensure that the minimum distance between the installation of the bottom lamp is 12m (15m for two venues; Three venues are 18m).
For a single tennis court for general entertainment, the height of the light pole is at least 8m (two are 11m; Three for 14m), the light pole is arranged outside the side line, each side can be cloth 2 light poles, can also be set up 3 light poles (using floodlights).
Illuminance uniformity:
The ratio of minimum and maximum vertical illuminance should not be less than 0.4.
The ratio of the average vertical illuminance to the average horizontal illuminance of the site should not be less than 0.25.
The ratio of minimum and maximum horizontal illuminance of the site should not be less than 0.5.
The vertical illumination of the front row of the audience should not be less than 0.25 of the vertical illumination of the venue.
Glare suppression:
The suppression of glare plays an important role in the performance of athletes, the evaluation of referees and the appreciation of spectators. Therefore, glare control should be taken into account when selecting lamps and arrangements.
Environmental factors:
The height of the enclosure net around the outdoor tennis court is generally between 4-6 meters, and the surrounding environment (the height of trees or buildings) can be increased or decreased appropriately.
In order to accurately calculate the lux value of an outdoor tennis court, professional lighting design software or field measurements are usually required. In practical applications, it is recommended to consult a professional lighting designer or engineer to ensure that tennis court lighting meets the needs of competition and use.
