Semiconductor optoelectronic devices "high-tech tip" technology, with online programming, unlimited upgrades, flexible and changeable characteristics
What are the differences in lighting installations in different stadiums?
1. Lighting method of swimming pool
The classification of swimming pools can be divided into natural swimming pools and artificial swimming pools. The length of the official competition is 50m, the width is 25m, there are 8 to 9 swimming lanes, each of which is 2.5m wide, separated by water lines, and the water depth is more than 1.8m. If the depth of the swimming pool for swimming, diving, water polo competition and other comprehensive sports is about 1.3 to 1.5m; the depth of the pool with a 10m diving platform is 5m, and the pool wall must be 0.3m above the water surface.
2. Tennis court lighting method
Lighting committee tennis court lighting standards. The tennis court is divided into indoor and outdoor, and the lighting is also natural light and artificial light. The size of the tennis court is 23.744m in length, 10.974m in width and 0.9～1.06m in height. Tennis balls usually move at high speed in a short distance, and it is necessary to judge the running direction of the ball in a short time. Therefore, tennis requires high visual demand. The lighting of indoor tennis courts should not be arranged above the PPA (Basic Competition Area). If there are lights above the PPA, the bright light source will cause serious glare to the athletes. Therefore, the lamps should be placed in the space outside the PPA. In addition, at the ball net, the installation height of the luminaire is 9.144m; at the bottom line, the installation height of the luminaire should not be less than 9.096m.
3. Lighting method of track and field field
Track and field competitions are generally set up in high jump, long jump, pole vault, throwing and football and other sports. The surrounding area is a runway. The standard running distance is 400m, and there are usually stands on both sides or one side of the field. There are generally three ways to install lamps in track and field: pole installation, tower installation and the use of the stadium itself to install the lamps. For pole-mounted and tower-mounted installations, light poles or lighthouses should be at least 1m away from the outer edge of the runway to prevent athletes from being hit and injured. The height of the light pole or lighthouse is about 45m. The proper installation height is essential to control the glare in the arena and reduce the overflow light outside the arena. The best result is to ensure that the glare index GR is less than 50.
4. The way of lighting the football field
FIFA stipulates that the length of the football field is from 105m to 110m and the width is from 68m to 75m. There should be no obstacles within at least 5m outside the bottom line and sideline of the court to ensure the safety of athletes. There are two basic layouts for venue lighting: four-corner layout (lamps are installed on the tall tower on the diagonal extension of the stadium), the installation position of the four-corner lighthouse with light The height is calculated as follows: h=dtgφ, h=the height of the lighthouse; d=the distance from the tee point of the court to the lighthouse; the angle between the tee point of the court and the bottom and top of the lighthouse must be greater than 25 degrees; lateral direction The arrangement of lighting fixtures is relatively low, and the lighting fixtures are located on both sides of the court. The lateral arrangement can be subdivided into two ways: multi-tower (pole) installation, with 2, 3 or 4 towers (poles) on the side of the stadium; light belt installation, the lamps are installed on the ceiling or the horse track, and the lights are formed in line with the stadium during lighting. Light strips with parallel sides.
What issues should be paid attention to when selecting lamps for stadiums?
(1) The light distribution of the luminaire should be compatible with the installation height, location and lighting requirements of the luminaire. Outdoor stadiums should use narrow beam and medium beam lamps, and indoor stadiums should use medium beam and wide beam lamps.
(2) Lamps and accessories should be able to meet the requirements of the use environment. The lamps should have high strength and corrosion resistance. All the lamps and electrical accessories must meet the requirements of heat resistance.
(3) Open-type lamps should not be used for metal halide lamps. The protection level of the lamp housing should not be less than IP55, and the protection level of places that are inconvenient for maintenance or severely polluted should not be less than IP65.
(4) The account opening method of the lamp should ensure that its aiming angle is not changed during maintenance.
(5) The lamp should be equipped with or attached to the indicating device to adjust the angle. The lamp locking device should be able to withstand the maximum wind load under the conditions of use.
(6) Light weight, small size and small wind load coefficient should be selected for the lamps installed in the high air.
(7) The lamps should have anti-glare measures.
(8) The lamps and their accessories should have anti-falling measures.
What should be paid attention to when installing stadium lighting?
One, lighting specifications
Lighting designers should consider various national index values when developing overall planning. Stadium lighting is different from general engineering architectural lighting, and the overall planning of the lighting specifications must be carried out in accordance with the requirements of the relevant specifications.
Two. Light source selection
The light source should have suitable color temperature, excellent color rendering index, high special effects, long life and stable lighting and optical characteristics. The output power of the light source should be consistent with the size, installation location and height of the playing field. Outdoor stadiums should use high-power and medium-power LED lamps and metal halide lamps, and ensure that the light source works continuously or quickly.
Three, lighting fixtures
The safety factor of lamps and accessories should meet the requirements of actual relevant codes. The lighting characteristics of gymnasiums are the large direct lighting space, long distance, and high light intensity technical standards. Therefore, the lighting of the venue generally uses high-efficiency and long-life technical professional light distribution lamps.
Four, lighting installation
The installation position, height, and projection angle of the luminaire should be considered to reduce glare and affect the standard requirements of the light. Different sports, different levels of competition, there are different norms on the limit value of glare, outdoor stadiums: GR≦50GR≦40 (fixed camera orientation).
