Table Tennis Court Lighting Design

Standard size of table tennis court

Table tennis is a popular ball sport in the world and is also the national ball of the People’s Republic of China. Table tennis is a skill-based project that is mainly technical and supplemented by physical fitness. It originated in the United Kingdom. The name “ping pong” originated in 1900, and was named for the sound of “ping pang” when hitting it. In China, Hong Kong, and Macao, the official name is “ping pong”.

The table tennis court is rectangular, its length must not be less than 14 meters, its width must be not less than 7 meters, and the ceiling height must not be less than 4 meters. The competition area should be surrounded by a dark bezel with a height of 75 cm to separate it from the adjacent competition venue and spectators. The ground and the playing field should be solid non-slip hardwood. The floor should not be light-colored or significantly reflective. The baffle should be light and secure, so as not to be injured when the athlete hits the baffle. The baffle is 1.4 meters wide.

Table tennis court lighting design standards

There should be good illumination and uniformity of illumination at a high altitude above the playing field, but glare should be avoided to the athletes. There should be no shadows on the ping-pong table. At the same time, the shadow of the surrounding shields should be avoided. The ratio of the vertical illuminance on the four sides of the playing field shall not be greater than 1.5. Lighting and Broadcasting Requirements (1) The vertical illuminance and uniformity of the camera direction of the table tennis court must meet the requirements of video and broadcast. (2) The color temperature of the table tennis court will affect the adjustment of the camera ’s white balance. For table tennis courts at the broadcast level, T cp> 4000K (-general broadcast) or 5500K (high definition broadcast) is required; (3) Color rendering index will affect the degree of color reproduction of broadcast and video. For broadcast table tennis courts, Ra> 80 (general broadcast) or Ra> 90 (high definition broadcast); (4) The installation position and projection angle of the ping pong court lamps sometimes cause glare to the camera. Illumination uniformity, glare, color temperature, color rendering, etc. are all judging standards for table tennis court lighting standards

Lighting control and installation specifications for table tennis courts

The lighting of the competition halls of stadiums, stadiums and swimming pools above Grade A shall be provided with a centralized control system and located in a dedicated control room.
