First, badminton venue standards
The badminton court is a length of 13.40 meters, doubles width 6.10 meters, singles width 5.18 meters, doubles stadium diagonal length = 14.723 meters, singles stadium diagonal length = 14.366 meters. The center of the site is divided by the net (the height of the columns on both sides is 1.55 meters and the height of the intermediate net is 1.524 meters).
The horizontal direction of the badminton court is divided into two left and a half areas by the middle line; the vertical direction is divided into the front field, the middle field and the back field. The frontcourt is a field from the front tee line to the net; the backcourt refers to a field between the end line and the double-playing tee line; the midfield is a field between the front tee line and the double-player tee line.
According to the international competition regulations, the space above the stadium is at least 9 meters. Within this height, there must be no beams or other obstacles. There must be no obstacles within 2 meters of the course. There should be at least 2 meters between any two courses that are juxtaposed.
Therefore, the installation height of badminton court lamps, professional-grade stadium lights should be at least 9 meters above the ground, and should be equipped with anti-glare devices. Entertainment and training level venues can be appropriately lowered in installation height.
Second, badminton court lighting features
There are usually three forms of lighting in a badminton hall: natural lighting, artificial lighting, and hybrid lighting that are used together. Most of the modern badminton courts are mixed lighting, and the artificial lighting of the badminton court is general lighting. In the design of the badminton hall, to make the athlete accurately judge the ball path, height and drop point, the first is to make the best use of natural light, the effect of natural light is the best, of course, to prevent glare, not to allow excessive light or Reflected into the eye. The second is to increase the stability of the illumination and the uniformity and coordination of the distribution. This is not only important for athletes to achieve excellent results, but also for the accurate judgment of the referee and the appreciation of the audience. Therefore, the stadium lights are especially important in these aspects of badminton court lights.
Third, the influencing factors of badminton court lighting quality
1. Illumination level: Whether the illumination level meets the standard.
Generally speaking, the vertical illuminance should be greater than 1/2 of the horizontal illuminance. When the vertical illuminance is equal to the horizontal illuminance, the moving environment is optimal. The badminton court illumination requirements are as follows:
2. Uniformity of illumination: Whether the illumination of the sports ground is uniform.
The uniformity of illumination is used to measure the visual conditions within the venue. Uniformity means that the venue should be able to be evenly illuminated, and there should be no areas that are too bright or too dark to provide good visibility for athletes, spectators, and referees. For example, for TV broadcast, when the camera captures the panorama of the game area, the illuminance cannot be greatly changed, otherwise the camera will be exposed.
3. Glare: Is glare obvious?
Glare is another important factor in evaluating the quality of lighting. The generation of glare is related to the installation method of the luminaire, the installation height, the number of luminaires and the installation density, and the light distribution of the luminaire. When there is too high brightness contrast in the field of view, people will feel glare and affect people's visibility. If you look at the sun in the middle of a sunny day, you will feel that you can't blink. This is the glare caused by the high brightness. The glare of the badminton court is direct glare. Because the ceiling is low, the light source is very glaring when the athletes are exercising. The eyes are uncomfortable for a long time, which seriously affects the athlete's observation of the movement of the ball.
4, brightness ratio: the color and brightness difference between the object and the background.
The eye can distinguish objects on the background. There must be one of two conditions, that is, the background is different from the color of the object, or the background has a certain brightness contrast with the object. If the object is darker and the background is darker, the better the vision; otherwise, if the background is brighter than the object, the vision will drop significantly. When the lighting conditions are very poor, especially when there is a lack of brightness difference, it may cause false visual phenomena, distorting the perceived object, and adversely affecting important information.
The color of the badminton is white and the background wall is white, which will cause the sportsman to see the ball. In order to increase the difference between the color of the badminton and the background wall, the light and shadow effect of the lamp is used to reduce the brightness of the background wall. The opaque lampshade can be used to block the shadow of the lampshade from being projected onto the wall, while another part of the light is irradiated onto the ground, and the reflection is irradiated into the field, thereby reducing the brightness of the background wall, making the badminton and the background contrast greatly, and making the badminton sport more clear.
5, the stability of lighting: whether there is strobe.
The stability of lighting directly affects people's health, and unstable lighting can lead to reduced vision of athletes. Lighting stability is mainly reflected in the stroboscopic effect. The stroboscopic is the periodic change of the current when the AC power is supplied, and the luminous flux also changes periodically, which causes people to observe the moving object and cause illusion. The periodicity of the current changes, causing the source to be unstable. This results in significant stroboscopic lighting. When observing the movement of the badminton, you can see a relatively blurred shadow with low resolution.
Fourth, commonly used lamps
In the badminton court new site and badminton court lighting renovation, we recommend the use of professional spotlights and high-efficiency stadium LED lights, both lamps can bring customers professional, comfortable and lighting environment, but also in the current domestic badminton courts High-end lighting products. At the same time, the lamps are also suitable for indoor sports venues such as indoor tennis court lighting, indoor basketball court lighting, badminton court lighting, indoor integrated stadium lighting.
Stadium professional spotlight performance features: light fixtures, easy to handle handles, with 360o adjustable mounting brackets; also equipped with precise sight accessories, installed at the top or low end of the lamp body; ambient temperature: Adapted to indoor and outdoor routine weather use; through gradual improvement, the luminous efficiency of the lamps and the effective utilization of light are greatly improved; this series of lamps is designed for sports field lighting, allowing the athletes and audiences on the scene as well as the TV viewers to better participate and Feel the excitement and excitement of the game. The unique elliptical optical system cooperates with the new light source to ensure high overall reliability, low glare and optimal lighting level, compact appearance, low drag coefficient and light weight. The luminaire has a unique design of the light distribution curve; the beam is precise, a variety of light distribution, instant start and so on.
Efficient floodlight stadium LED lamp performance characteristics: patented "fin" heat dissipation structure design LED heat dissipation area is larger, thermal conductivity performance is better, not only effectively reduce the temperature rise of LED junction, long-term use of low luminous flux attenuation and longer life, At the same time, the product is lighter in weight and has high safety performance. It is a unique high-tech LED lighting product on the market. The unique asymmetric illuminating lens concentrates the light evenly on the surface of the object, avoids the loss of light, and greatly improves the light utilization efficiency and the surface brightness of the object. It is an ideal indoor and outdoor venue lighting fixture.
