Stadium Lights

Stadium Lights

Stadium lights are mainly used to install multiple lamps on various poles around outdoor basketball courts, tennis courts, badminton courts, and football fields; general basketball court lights, badminton court lights, tennis courts, and 5-person / 7-person football stadium light poles The height is about 8-12 meters. There are 2 to 6 spotlights on each light pole. Standard professional football stadiums and stadiums use 18–40 meters high pole lights as the poles of the lamps. Configure the number of lamps and the style and power of the flood light according to the design requirements; the light pole is rolled with Q235 high quality steel plate, hot-dip galvanized inside and outside, and the surface is sprayed with plastic or paint; rust and corrosion resistance; durable for more than 30 years; Dongguan The stadium lights produced by Qidu Lighting are widely used in school \ factory \ high-end community \ community and other places such as activity squares, playgrounds, basketball courts, football fields, badminton courts, tennis court lighting, and professional and stadium, golf course lights, etc. Outdoor stadium lighting.

Lighting requirements for modern stadiums:

1) Illumination

In addition to the reasonable illumination, the athletes can play normally and the referees can make accurate judgments. They can also ensure that the audience on the scene and in front of the TV can watch the game comfortably. Different sports also require different illumination levels. The illumination required for sports events, business activities, etc. also varies.

2) Lighting uniformity

The ratio of the minimum illumination value to the maximum illumination value is the illumination uniformity. Whether it is an indoor stadium or an open-air stadium, the lighting requirements are very high. Take basketball stadiums as an example, the middle venue tends to gather more light, but the areas with excessive light often produce glare, and the rebound area The brightness of the light will be weak, ensuring the uniformity of the lighting of the overall venue, which is of vital importance to the level of the athletes.

3) Glare

In order to ensure uniform illumination at all angles and prevent glare indoors, the elevation angle of the lowest point of the stadium’s light projection to the lamp must be greater than 45 °. The audience caused direct light, and now stadiums will use computers to calculate the light projection point to ensure the uniformity and reasonable distribution of light. Indoor glare can also be caused by different floor materials or water reflections from swimming venues, so grilles or baffles can also be added to the lamps to reduce glare.

Stadium light color-Cold white

The cold white light source is close to natural light and has a bright feeling, which makes people focus. The warm color light is similar to the incandescent light color, with more red light components, giving people a warm, healthy and comfortable feeling. concentrated.

The color of the stadium fixtures is generally white. The average court uses metal halide light sources, as well as magnesium filament lamps. The pitch is generally 1000w. Of course, it depends on the brand, wattage, whether it is installed, etc. Most current sports and architectural lighting design standards do not make clear regulations and requirements for golf lighting design standards, especially in China. Therefore, different lighting companies often refer to the lighting design experience of other industries to design night lighting stadiums, and the night lighting effects of different stadiums will be significantly different.

What are the advantages of stadium lighting for professional sports lighting?

Standard five-person basketball courts generally use 400W metal halide lamps or sodium lamps, but metal halide lamps are expensive, not durable, and consume a lot of power. They also have a long life and require frequent maintenance. With the continuous improvement of LED lamps, many basketball courts have replaced LED lamps today. A 120W Huaxia Beidouxing LED court special lamp can completely replace the 400W metal halide lamp, and the energy saving is close to 2/3.

LED is a revolutionary third-generation lighting source. It is recognized as a high-tech, environmentally friendly, efficient, energy-saving, and green product. The country vigorously promotes energy-saving and emission reduction, and implements and supports the application of LED lighting products.

LED stadium lights have no filament, no glass bubbles, are not afraid of vibration, and are not easily broken. The service life can reach more than 50,000 hours, and the overall cost is very low. LED stadium lights have no electrodes and have a very long service life, making them ideal for basketball court lighting! Traditional stadiums generally use 400W metal halide lamps or sodium lamps. Although they are cheap, they are not durable, and they consume electricity, have a short life span, and require frequent maintenance. With the development trend of LED lamps, many stadiums now use LED lamps. A 160W LED lamp can completely replace a 400W metal halide lamp, saving more than half of energy. LED lamps not only save energy, but also have a lifetime of up to 50,000 hours. There is no flicker when the lamp is in operation, and it lights up immediately, which greatly improves the enjoyment of playing.

Selection of outdoor basketball court lights

First, the basketball court is a rectangular solid surface without obstacles. For the main official FIBA ​​matches, the measurement of the pitch must be measured from the inner edge of the boundary. For all other games, the appropriate department of the FIBA ​​has the right to approve existing courses within the following size ranges: 4 meters in length and 2 meters in width, as long as the changes are proportional to each other. The ceiling or lowest obstacle property must be at least 7 meters high. The court should be evenly lit and have sufficient light. The placement of lighting equipment shall not impede the vision of the team members. The dimensions of all new stadiums should be consistent with the requirements set by the main official FIBA ​​matches: 28 meters long and 15 meters wide.

What kind of lighting is suitable for outdoor basketball court lighting, halogen light or LED flood light?

First, halogen lamps (metal halide lamps HID) as a lighting source for outdoor basketball courts were popular in a certain period of time. With the advantages of high brightness, good luminous efficiency, and convenient maintenance, halogen lamps were first widely used in outdoor large billboards, stations, docks, and industrial and mining enterprises, and then introduced to outdoor basketball court lighting. A standard outdoor basketball court (32×19 meters) ) With 4-6 halogen lamps of about 400W, it can fully meet the needs of basketball court lighting. The halogen lamp also has the advantages of long range, strong penetrating power and uniform light emission, so even if a small number of lamps are installed at a place far from the sideline of the court, the lighting requirements of the basketball court can be realized. The disadvantages of halogen lamps are that they have relatively high power and low energy consumption ratio, and that the light intensity is too high and long-term exposure to such light will affect the visual judgment of athletes.

Second, LED flood light is now the mainstream choice for outdoor lighting. Due to its advantages of low energy consumption, small size, light weight and high luminous efficiency, it is becoming a priority choice in various fields of outdoor lighting. LED flood lights have widely entered the field of outdoor basketball court lighting and have only risen in recent years. Based on the light-emitting principle of LED lights, the advantages are of course countless. Obtaining efficient lighting effects with low energy consumption also meets the basic requirements of building a resource-saving and environment-friendly society in China, and it is also a low carbon The meaning of environmental protection; soft light is more in line with the visual perception of the human body, helps the visual judgment of the human body, and is a high-quality option for outdoor basketball court lighting. Of course, compared to halogen LED flood lights, due to the weak light intensity and insufficient penetrating power, scientific verification is still needed in specific fields such as high altitude. Specific issues and specific analysis must not be used blindly.

1.In summary, we should follow the following basic principles in the selection of lighting fixtures for outdoor stadiums:

2.Respond to the mainstream of low-carbon and environmental protection society, choose LED flood lights with high cost performance and high energy consumption ratio as outdoor basketball court lighting fixtures;

3.Specific problems and specific analysis, follow the pragmatism, different court sizes, different heights of light poles, and different surrounding environments of the court allows the use of halogen lamps as outdoor lighting fixtures;

4.The types of lamps used as outdoor basketball court lighting will also change with the continuous progress of lighting technology. We should also look at the development of the outdoor stadium lighting industry with a development perspective.

Badminton court lights

Badminton court lighting LED, light illumination 300LX, our LED lamps are tailored according to the different characteristics of the court, anti-glare, high uniformity, non-glare, comfortable, without any light pollution. The lamp body is made of high-quality aviation aluminum profile, which has higher heat dissipation efficiency; and adopts phase change heat dissipation technology and the structure adopts air convection design to ensure the heat dissipation effect; The light source uses imported high-quality high-power lamp beads, with high brightness, light color integrated with the court, long life, softer light.

Stadium lighting design focuses on stadium lighting, that is, competition lighting. The venue lighting is a highly functional, highly technical and difficult design. To meet the requirements of various sports events, it is conducive to the development of athletes’ technical level, the correct judgement of referees, and the viewing effect of various parties in the auditorium. The design of the stadium should pay special attention to the live broadcast of color TV. In order to ensure the vividness and vividness of the broadcast image, the vertical illumination, uniformity and three-dimensional sense of illumination, color temperature and color rendering of light sources have specific requirements. Therefore, Wanye Lighting thinks whether the stadium lighting design can meet the requirements of illuminance standards and lighting quality, which is the main symbol for evaluating a stadium.

Modern sports are constantly developing with the development of human society. Sports are inseparable from the construction of stadiums. The lighting design of the stadium is characterized by the large space of light irradiation, long distance, and high illumination technology requirements. Therefore, the venue lighting generally uses high-efficiency, long-life professional light distribution lamps.

The choice of light source

1. For stadiums with high installation height, the light source should be high-hanging fluorescent lamp, high-efficiency LED flood light, and metal halide lamp.
2. Indoor stadiums with low ceilings and small areas should use high-hanging fluorescent lamps and low-power LED lamps.
3. Special light sources can be used in special places, such as explosion-proof lamps.
4. The power of the light source should be compatible with the size, installation position 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 uninterrupted e. The light source should have a suitable color temperature, good color rendering, high light efficiency, long life and stable ignition and photoelectric characteristics .
5. Glare has a direct relationship with the lighting mode, installation height, angle, and lamp power. For places with high glare requirements, it is recommended to use high-hanging fluorescent lamps or adjust the height and angle to reduce the glare of the lamps.
6. Luminous mode: point light source (LED, metal halide lamp), characteristics, high single point light efficiency, large glare, difficult to control; surface light source (high hanging fluorescent lamp, high hanging LED lamp), uniform illumination, low glare.
7. Low glare; uniform light distribution, built-in anti-glare and anti-overflow devices.

The relevant color temperature and application of the light source can be determined according to the following table. Correlated color temperature and application of light source
