The illuminance of the basketball court lighting is 15lux
You can make an assumption. If the illuminance of a basketball court is 15lux, how to upgrade to 300lux? If more lamps are added, then light poles will be added. However, if there are too many light poles around a basketball court, the probability of golfers installing light poles is high, which is not safe. What about without a light pole? Then the number of lights on each pole will increase, and the overall windward surface of the pole will also increase, which is not safe enough. How about replacing more powerful lamps? It seems reasonable. But basketball court lighting is still a bit technically difficult.
Usually, the entire basketball court is 28 meters long and 15 meters wide. Some stadiums have 4 light poles, and some have 6 light poles. With certain restrictions on the number, position, and height of the light poles, it is difficult to control the uniformity of the basketball court lighting. The area far away from the surrounding four lights is definitely darker. This issue was taken into account when designing stadium lighting fixtures. Stadium lighting fixtures have high luminous efficiency, long range, and a variety of light distribution curves. There are lenses with narrow, medium, and wide angles to choose from. The light distribution is flexible, which is convenient to improve the uniformity of stadium lighting and effectively prevent overflow.
