A Comprehensive Guide to Basketball Court Lighting Design
A Comprehensive Guide to Basketball Court Lighting Design
The lighting of the stadiums is an important part of the stadium design, and it is more complex. It should not only meet the requirements of athletes to compete and audience to watch, but also meet the requirements of color temperature, illumination and illumination uniformity of shooting movies and TV broadcast, which is far higher than that of athletes and audience. In addition, the way of lighting lamps should be closely coordinated with the overall planning of the stadium and the structure form of the stands. In particular, the maintenance of lighting equipment is closely related to the architectural design. Should have comprehensive consideration.
Modern stadium generally adopts high-power LED high mast lights, which has high light efficiency (about 160 lm/W, high color rendering, color temperature between 5000-6000K, can meet the requirements of high definition color TV (HDTV) for outdoor lighting. The general life of light source is more than 100000h, the efficiency of lamps can reach 95%, the dust-proof and waterproof grade of lamps requires IP65, and the commonly used high-power stadium lamp can reach IP66/IP67.
First quarter. International sports federation about basketball, volleyball lighting standard value
International Sports Federation (GAISF) lighting standards for basketball and volleyball
Note: 1. Venue size: basketball 19m * 32m (PPA: 15m * 28m); volleyball 13m * 22m (PPA: 9m * 18m).
2. Best position of camera: the main camera is set on the vertical line of the competition field, with the standard height of 4-5 m; the auxiliary camera is set on the goal, sideline,the back of the bottom line.
3. The calculation grid is 2m * 2m.
4. The measurement grid (best) is 2m * 2m, and the maximum is 4m.
5. As the athletes look up from time to time, avoid the parallax between the ceiling and the lamp.
6. According to the International Amateur Basketball Federation (FIBA), new sports facilities will be held with a total area of 40m * 25m
The normal vertical illumination requirement is not less than 1500 lx. The lighting lights (when the ceiling is polished) should be arranged to avoid causing glare to the athletes and spectators
7. It is estimated that the field size of platoon (FVB) is 19m * 34m (PPA: 9m * 18m) and the minimum vertical illumination in the main camera direction is 1500lx
Section 2. Selection of lighting facilities for the Basketball Stadium
1. Selection of stadium lights:
1. Use high power LED lights.
2. The ceiling is low, the area is small indoor gymnasium, should use low power floodlight.
3. Flick-free, long-life lamps.
4. The power of the light source shall be suitable to the size, installation position and height of the competition field. Outdoor stadiums should use high power and medium power court lights to ensure that the light source works uninterrupted or fast start.
5. The lights should have suitable color temperature, good color rendering, high light efficiency, long life and stable lighting and photoelectric characteristics.
6. The relevant color temperature and application of the light source can be determined according to the table below.
The related color temperature and application of the light source
correlated colour temperature (K)
5. Light pole and setting requirements
When the four-tower type, multi-tower type or tower belt mixed lighting mode is used on the spot, it is necessary to choose the lighting pole as the carrier of the lamps and lanterns. Lighting light pole in the case of meeting the requirements of lighting technical conditions, the relationship with the building mainly has the following ways.
1. The lamp pole is independent of the main building, which exists alone as an independent equipment and is widely used currently.
2. The lamp pole is attached to the main building, but it is not combined with the main building as a whole. The foundation of this form may be different from the foundation form of the building, which needs to be treated separately.
3. When the lamp pole is attached to the main building and combined with the main building as a whole, this form can deal with the aesthetic problem very well. If this scheme is feasible, this scheme can be given priority.
4. The light pole shall be set up for obstacle lighting according to the aviation management.

(2) The layout of lamps in the outdoor basketball court shall comply with the following provisions
1. When there is no TV broadcast, use the lamp on both sides of the venue.
2. The lamps should not be arranged within the center of the ball frame at the bottom of the ball line and the bottom line, the distance between the bottom of the lamp pole and the Angle between the site plane should not be less than 25 degrees.
3. Under any lighting method, the layout of the light pole should not hinder the sight of the audience.
4. Symmetrical lamps shall be arranged on both sides of the site to provide the same lighting.
