Sports Venues

The function of a modern large-scale comprehensive gymnasium must not only meet various large-scale competitions, but also undertake different large-scale theatrical performances, rallies and other tasks.
The hall is divided into the main arena and the general arena, usually including badminton hall, table tennis hall, volleyball hall, tennis hall, basketball hall, track and field venue and its supporting functional areas.


Holding different events in the same venue can indeed save resources to a certain extent, and a multi-purpose game can also avoid wasting the venue, but there are also certain problems in this way. Sports games and cultural performances require different lights. , basketball games and table tennis games also have different requirements for illumination, and even regular games and daily training are two environments, which requires the lighting of the playing field to be able to switch between different modes! A single light can no longer satisfy more and more diverse venues!
Lighting is one of the important links in which the functions of the gymnasium can be fully reflected. Among them, the focus of stadium lighting is sports field lighting, that is, competition lighting; followed by general lighting, auditorium lighting, emergency lighting, venue lighting, building interior lighting, indoor lighting and road lighting. Wait.
These are important components of stadium lighting; how to meet the scene lighting of various competition venues, so that the color temperature, illuminance, glare, color rendering index, etc. can all meet the specified standards. It's not just the choice of lamps, but also the choice and distribution of the lighting system.
Stadium lighting is a powerful, high-tech, and difficult-to-stop design. In order to meet the requirements of various sports competitions, it is conducive to the technical level of sports products, the correct evaluation of referees and the viewing effects of all aspects of the audience. The stadium should pay special attention to the live broadcast of the color TV.


In order to ensure that broadcast images are vivid, clear, and realistic, there are specific requirements for indicators such as vertical lighting, lighting uniformity and one-dimensionality, light source color temperature and color display.
1. The choice of light source:
1. For stadiums with high lamp installation height, the light source should use high-hanging explosion-proof lamps and high-efficiency LED floodlight lamps.
2. For indoor gymnasiums with low ceiling and small area, low-power LED lamps should be used.
3. The light source in special places can use special lamps, such as explosion-proof lamps.
4. The power of the light source should be compatible with the size of the competition field, installation location and height. Outdoor stadiums should adopt high-power and medium-power LED explosion-proof lamps, and ensure that the light source works uninterrupted or starts quickly.
5. The light source should have suitable color temperature, good color rendering, high light efficiency, long life and stable ignition and photoelectric characteristics.
6. Glare is directly related to the lighting mode, installation height, angle, and power of the lamp. For places with high glare requirements, it is recommended to use high-hanging explosion-proof lamps or adjust the height angle to reduce the glare of the lamp.

4. Lamps should have a variety of light distribution forms. Stadium lighting lamps can be classified according to the following table: Classification of flood lamps
Beam Classification Beam Angle Range (degrees) Narrow Beam 10~45 Medium Beam 46~100 Wide Beam 100~160


Note: Classified according to the opening angle of 1/10 of the maximum light intensity of the beam distribution range.  
(1) The light distribution of the lamps should be compatible with the installation height, position and lighting requirements of the lamps. Narrow beam and medium beam lamps should be used for outdoor stadiums, and medium beam and wide beam lamps should be used for indoor stadiums.  
(2) Lamps should have anti-glare measures.  
(3) The lamps and accessories should meet the requirements of the use environment. The lamps should be high in strength and corrosion-resistant, and the electrical accessories of the lamps must meet the requirements of the heat resistance level.  
(4) The protection level of the lamp shell should not be less than IP55, and the protection level of places that are not easy to maintain or seriously polluted should not be less than IP65.  
(5) The lighting method of the lamp should ensure that its aiming angle is not changed during maintenance.  
(6) Lamps installed in high altitude should choose products with light weight, small volume and small wind load coefficient.  
(7) The luminaire shall have its own or be attached with an indicating device for adjusting the angle. The locking device of the luminaire should be able to withstand the maximum wind load under the conditions of use.  
(8) The lamps and their accessories shall have anti-drop measures.


3. Commonly used lamps
