Schools where general conditions permit are equipped with indoor basketball courts and outdoor basketball courts. Compared with outdoor basketball courts, indoor basketball courts have two greater conveniences. On the one hand, they are not affected by the weather and can still be carried out in rainy and snowy days. It will not be postponed or cancelled due to various weather reasons like outdoor basketball courts; on the other hand, indoor basketball courts can be arranged with more spectator seats, while outdoor basketball courts are generally directly surrounded by fences, so they are generally large or the games that need to be recorded are on the indoor basketball court.

Lighting is a very important facility for indoor basketball courts. How many basketball stadium lights are generally installed? What kind of lights are generally used for basketball stadium lights? The installation and construction requirements for basketball stadium lights are all related to the corresponding regulations and standards. Now Bbier hope this article may help you guys learn the comprehensive knowledge of basketball stadium lights design.

What are the requirements for basketball stadium lights?

With the increasing development and popularity of sports and competitions, more and more participants and people watching the game, the requirements for basketball stadium lights are getting higher and higher. The basketball stadium lights must ensure that athletes and coaches can see clearly All the activities and scenes that take place on the playing field, so that they can achieve the ideal performance, the audience must also follow the athletes and the game in a pleasant environment and comfortable conditions.

What kind of lamps are suitable for basketball stadium lights? This requires us to return to the essence of sports lighting-functional requirements. For the audience rating, sports events are generally held at night, which destined many stadiums to be a big consumer of electricity, so energy saving has become the primary pursuit of basketball stadium lights. When it comes to energy-saving products, LED lamps are the best. Compared with traditional light sources, LEDs can save energy by 50% to 70%. Traditional lamps, such as high-power metal halide lamps, have an initial lumen output of 100lm/W and a maintenance factor of 0.7 to 0.8, but most venues have a light decay of more than 30% after 2 to 3 years of use, not only the output of the light source itself The attenuation of the lamp, and includes factors such as oxidation of the lamp itself, poor sealing performance, pollution, respiratory system problems, etc., the actual lumen output is only 70lm/W.

With its unique characteristics such as low power consumption, adjustable color quality, flexible control, and instant ignition, LED lamps are more suitable for stadium lighting. For example, Bbier’s sports stadium lamps have an efficiency of 130-150 lm/W and a constant illuminance output of 5000 hours, ensuring a constant level and uniformity of illuminance in the venue, and avoiding the increase in the demand and cost of lighting equipment due to the attenuation of illuminance , While reducing the power consumption of lighting equipment.

“People-oriented” is the purpose of lighting. Basketball stadium lights are no exception. A healthy light environment is a must. In the lighting design of stadiums, glare and interference light are the primary unfavorable factors that affect athletes’ competitive level, and they are also important factors that affect the quality of TV broadcasts. Glare is an important indicator that affects light health and light environment. Glare refers to the visual conditions that cause visual discomfort and reduce the visibility of objects due to inappropriate brightness distribution or extreme brightness contrast in space or time in the visual field. There is a sense of light in the visual field that the human eye cannot adapt to, which may cause disgust, discomfort or even loss of clarity. It also refers to the presence of excessively high brightness in a certain part of the field of view or excessive brightness changes before and after. Glare is one of the important causes of visual fatigue.

In indoor venue lighting, the sports lighting level is I, and when the use function is fitness or amateur training, the glare value (GR) should not be greater than 35, and the glare value of other sports lighting levels should not be greater than 30; in outdoor venue lighting, the sports lighting level It is I, when the use function is fitness or amateur training, the glare value (GR) should not be greater than 55, and the glare value of other sports lighting levels should not be greater than 50. LED stadium lighting can reduce glare and spilled light through the following measures:

1. Professionally designed lamps for LED characteristics, equipped with medium light distribution, narrow light distribution and extra narrow light distribution;

2. Scientific lens and reflector design to achieve effective control of light;

3. Make full use of the secondary reflection of the reflector to reduce direct glare;

4. Scientifically determine the working power of the LED light source to control its central light intensity;

5. Design a suitable external glare controller to reduce glare, and use re-reflection to improve light efficiency;

6. Control the projection angle and direction of a single different LED lamp bead.

Important events are generally broadcast live. In order to obtain high-quality images, the camera’s requirements for basketball stadium lights are naturally much higher. For example, for the stadium lighting of China’s Provincial Games, National Youth Games, and domestic individual events, the vertical illuminance of the main camera should be more than 1000lux. The illuminance of some football clubs operating abroad is often around 150lux, which is obviously several times higher.
The display index and color temperature have a greater impact on the camera screen. After the initial composition of the metal halide is determined, the photoelectric parameters of the light source, such as color temperature, color rendering, etc., have been fixed. The conventional ones can be selected from 65 (4000K), 80 (4000K), 90 (5600K), etc., but the ignition point varies with the light source With the increase of time, the metal halide in the quartz bulb.

How many basketball stadium lights are generally installed?

There are two main design options:

(1) The arrangement of gypsophila
Lighting fixtures on the top are arranged above the venue. The arrangement of the beam perpendicular to the plane of the field
The top layout should be the lighting fixtures with shaped light distribution, which is suitable for gymnasiums that mainly use low space, have high requirements for the uniformity of the ground horizontal illumination, and are required for TV broadcasting.

(2) Lamps arranged on both sides are arranged on both sides of the site, and the beam is not perpendicular to the plane of the site.
The step lights on both sides should use non-paired light distribution lamps, arranged on the horse track, and used in gymnasiums with high vertical illumination requirements. When arranging lights on both sides, the aiming angle of the lamps should not be greater than 66 degrees.

(3) Mixed arrangement, the top arrangement and the two sides arrangement are combined
The mixed layout should choose lamps with multiple light distribution forms for use in large-scale comprehensive gymnasiums. The arrangement of the lamps is the same as the top arrangement and the two sides arrangement above.

(4) According to the lighting layout of the lamps, it is advisable to use lamps with medium and wide beam light distribution-low floor height, large span and good fence reflection conditions in the building space, and it is suitable for strict restrictions on glare and no TV broadcast The required gymnasium is not applicable to suspended lighting fixtures and building structures where horse tracks are installed. In a symmetrical site, only some representative points need to be selected to measure the glare value.
