Common comprehensive venues need to meet the lighting requirements of badminton, basketball, football and other sports and large-scale activities. The sports lighting need to have anti-glare, high light efficiency, instant start, good stability and single fixture can be connected to the intelligent control system, which can greatly reduce the operation and maintenance costs of sports venues.
The quality of court lighting is mainly considered from the following five aspects:
- Glare: Whether glare is obvious.
- Lighting stability: whether there is flicker.
- Illuminance level: whether luminosity is up to standard.
- Brightness ratio: brightness difference between object and background color.
- Lighting uniformity: Whether the illumination of the sports field is uniform.
Generally speaking, the lighting of the football stadium is more complex, it not only needs to meet the requirements of the athletes and the audience, but also needs to meet the requirements of the color temperature, illuminance, illuminance uniformity of the television broadcast on the lighting, which is far higher than that of the athletes and the audience.In addition, the arrangement of lighting fixtures should be closely coordinated with the overall planning of the stadium and the structural form of the stands.
There are four ways of lighting distribution in football field: corner type, multi-tower type on both sides, light belt type arrangement on both sides and mixed type arrangement. What kind of lighting distribution mode should be chosen according to the specific situation of the stadium.In popular terms, the whole field should be irradiated evenly, and the area should not be too bright or too dark, so as to provide good visual conditions for athletes, spectators and referees. This also puts forward higher requirements for lighting distribution, safety Angle and court lighting design. The more professional the court, the higher the requirements.Due to the luminescent characteristics of its light source, most of the common leds have glare. Therefore, in the design of stadium lighting, it is necessary to focus on the glare. At the same time, the lens and anti-glare cover of the lamp are installed, and the important reasons for anti-glare are also fully considered.
In addition, in order to improve the utilization rate of the court, more and more indoor courts are considered to be built as comprehensive courts rather than traditional single-function courts, which not only improves the use efficiency, but also puts forward higher requirements for the construction of the court, especially the lighting. In addition to the complex lighting requirements for indoor venues, the lighting requirements for outdoor courts are also getting higher and higher. In addition to the ordinary like outdoor basketball is relatively simple, other like large football fields, golf courses, etc., the field lighting parameters, more and more subdivided, more and more professional. Like the light distribution of lamps, there are few requirements in the indoor court, because the space is not too large compared with the indoor court, the light distribution of lamps is basically a large Angle.
While in the outdoor court, the light distribution of the lamps is an important factor. The characteristics of the outdoor court are: large space, high pole installation, and far lighting distance. In order to achieve good uniformity, the small Angle of the lamps is especially important. The power and number of indoor basketball stadium lighting lamps are different from that of outdoor basketball courts. Generally, the power of indoor basketball stadium lighting lamps is 80-150W. Because of the vertical irradiation, the effective irradiation area of indoor court lighting lamps is smaller than that of outdoor court, so the number of lamps is significantly more than that of outdoor court.
