What is the lighting Standard of Basketball Court?

Basketball players are divided into amateur, professional, and professional. Similarly, basketball court equipment is also classified. For example, basketball court lighting, the industry standard (International Lighting Association) is divided into 6 categories: Ⅰ (training and Recreational activities), II (amateur competition/professional training), III (professional competition), IV (TV broadcast national/international competition), V (TV broadcast major international competition), VI (HDTV broadcast major international competition), of course, reality Among them, there are many basketball courts operating outside that have lower standards than I (training and recreational activities). Choose the lighting level of the basketball court according to the actual needs of your basketball court, and the cost performance will be high.

Several Concepts Related to Basketball Court Lighting

（1）Basketball court horizontal uniformity
Horizontal illuminance is the value measured when the illuminance meter is placed horizontally above the field. When measuring and calculating the maximum, minimum and average illuminance of the site, a 10mx10m grid is established on the site.

（2）Basketball court variation coefficient
Basketball is a high-speed sport. Maintaining a good uniformity of illumination on the court helps to improve the athlete’s on-site performance and create high-definition video recordings. The uniformity can be measured in the following ways, whether CV or UG can measure uniformity.

（3）Basketball court vertical illuminance
Field camera vertical illumination. Vertical illuminance refers to the vertical illuminance of the athlete. Too much vertical illumination changes will result in poor digital video quality. The designer must consider the balance of illuminance in all directions to reduce the unevenness of the illuminance when the field camera shoots.

（4）Basketball court color temperature

Color temperature is a sensation or phenomenon that describes the warmth (red) or coldness (blue) of illuminance. In the current digital camera technology, the camera can be adjusted according to the actual color temperature and contrast to obtain the ideal color quality.

（5）Basketball court color rendering index
Color rendering index is the ability of artificial lighting sources to restore natural light. The higher the color rendering index, the better the light color.

（6）Basketball court lamp selection
The selection of lamps involves the following aspects:
a. The quantity and cost budget of lamps,
b. The consistency and beauty of lamps,
c. Stable light emission, no flicker, no glare,
d. Strong and durable, long service life,
e. Waterproof rating is at least IP65 or above.

6 levels of basketball court lighting

Ⅰ. (Training and entertainment activities) The lighting standards of basketball courts conform to the basketball courts operated by foreign countries, the basketball courts in primary and secondary schools, and the internal basketball courts of the company. The lighting standard of basketball courts for training and recreational activities requires an average horizontal illumination of 300 lux, and the uniformity requirement is not high.
Ⅱ. (Amateur games/professional training) The basketball court lighting standards are in line with the advanced points of foreign-operated basketball courts, college basketball courts, county-level public basketball courts, and advanced basketball courts within the company. (Amateur competition/professional training) The basketball court lighting standard requires a horizontal average illuminance of 500 lux, and the uniformity requirement is relatively high.
Ⅲ. (Professional games) The basketball court lighting standards comply with the competitions organized by the provincial and municipal sports individual sports associations, with professional or professional athletes participating. (Professional games) The basketball court lighting standards require a horizontal average illumination of 750 lux, and the uniformity requirements are very high.
Ⅳ. (TV broadcast national/international competitions) Basketball court lighting standards comply with international invitation tournaments, general international single competitions, general intercontinental single competitions, international tours, national youth games, ethnic minority games, domestic general single competitions, domestic single series competitions, provincial games Meetings, that is, major countries and international competitions outside the scope of the international competition. (TV broadcast national/international competitions) Basketball court lighting must fully consider the requirements of camera contrast, while broadcast requires many cameras to work at the same time. For the relaying of basketball games, the main cameras need to be set on the stands on both sides of the arena; the auxiliary cameras are placed on both ends of the arena and used as close-ups of the athlete’s basket movement. The illuminance requirements in the direction of the main camera and the vertical illuminance requirements in the direction of the auxiliary camera will be different, which are 1000 lux and 750 lux, respectively. There are also certain requirements for the uniformity of illuminance in the vertical direction.

Ⅴ. (TV broadcasts major national/international competitions) The lighting standards of basketball courts are in accordance with the competitions organized by the International Olympic Committee, and various types of competitions held by the International Olympic Committee’s A-type international individual sports organizations (such as the Olympic Games, World Championships, World Cup, Intercontinental Cup) And corresponding qualifiers, etc.) as well as competitions held by the State General Administration of Sport (China Olympic Committee), and various types of competitions organized by national individual sports organizations recognized by the State General Administration of Sport (China Olympic Committee) (such as the National Games and National Championships) , National single league, etc.). The illuminance requirements in the direction of the main camera and the vertical illuminance in the direction of the auxiliary camera are 1400 lux and 1000 lux, respectively, which also have high requirements for the uniformity of the illuminance in the vertical direction.

Ⅵ. (HDTV broadcasts major national/international competitions) Basketball court lighting standards meet the Olympic Games, World Championships, World Cup, Intercontinental Cup (football, basketball, volleyball, table tennis, swimming, diving, and badminton, etc.), National Games, etc., or by TV broadcasters And other events as determined by the event requirements. The illuminance requirements in the direction of the main camera and the vertical illuminance in the direction of the auxiliary camera are 1400 lux and 1000 lux, respectively, and there are extremely high requirements for the uniformity of the illuminance in the vertical direction.

ROI—Return on investment in basketball court lighting

For a basketball court to achieve an average level of 300 lux, 16 300W Fengrui stadium lighting fixtures are required. These 16 basketball court lighting fixtures are installed on a 10-meter high pole. If all the lights are on at this time, the total power is 4800W. If the price of the electricity bill is 1.2 yuan per degree, then if you turn on the light for an hour, the electricity bill is 5 to 6 yuan, which is about 80 to 150 per hour relative to the venue. The cost is not expensive. However, the initial investment cost is large and the payback time is very long, so many venues do not pursue the minimum requirements of the International Lighting Association, especially non-profit basketball courts, such as rural public basketball courts, but in order to be able to play happily It will not make the illuminance too low, so it is now popular to let the illumination of the basketball court lighting be around 150 lux and 200 lux.

Arrangement of lamps

1、Layout lamps on the top–arranged above the site, the beam is perpendicular to the plane of the site.

The top layout should use symmetrical light distribution lamps, which is suitable for gymnasiums that mainly use low space, have high uniformity of horizontal illuminance on the ground, and have no TV broadcast requirements.
2、Arrange lamps on both sides–Arrange on both sides of the site, and the beam is not perpendicular to the plane of the site. Asymmetrical light distribution lamps should be used for the lamps on both sides. They are arranged on the road. They are suitable for higher vertical illumination requirements and TVs. The gymnasium required for rebroadcast. When placing lights on both sides, the aiming angle of the luminaire should not be greater than 65 degrees.

3、Mixed layout-a combination of top layout and two-sided layout, the mixed layout should use a variety of light distribution lamps, suitable for large-scale comprehensive stadiums. For the arrangement of lamps, see top arrangement and two sides arrangement.Traditional LED lighting installation VS Mobile light tower

4、According to the arrangement of light fixtures-it is suitable to use medium and wide beam light distribution lamps, suitable for building spaces with low floor height, large span and good reflection conditions of the top grid, and at the same time suitable for strict restrictions on glare and no TV broadcast The required gymnasium is not suitable for pendant light fixtures and building structures with horse tracks.

Basketball light fixtures should meet the following standards

  1. The rectangles should be arranged on both sides of the court and should be at least 1 meter beyond the end of the court.
  2. Lamp installation should not be less than 12 meters.
  3. Lamps should not be placed above the area within 4 meters in diameter centered on the basket.
  4. The illumination angle of the lamp should be as low as 65 degrees.
