With the vigorous development of China's sports industry, more and more cities are hosting various large-scale international and domestic major sports events. The construction of the stadium and the subsequent reuse will test the designers.
In addition to the structure and materials of the stadium, the stadium's ground materials, space height, illuminance, temperature, ventilation, and sound have strict requirements. Among them, lighting configuration is an extremely important part of the stadium design.
As a comprehensive venue for the stadium, the lighting requirements are also versatile. Not only must meet the requirements of competitions and live broadcasts of various sports events, but also meet the visual requirements of sports, staff and on-site audiences. At the same time, in addition to hosting sports events, the stadium will also host a variety of commercial performances, such as music concerts, concerts, large-scale events, etc., indoors should ensure sufficient illumination. In order to increase the value of the stadium, the versatile design can convert the highest added value with the most economical cost. In order to ensure the specific requirements of vertical illuminance, illuminance uniformity, spatial brightness distribution and modeling stereoscopic, color temperature and color rendering, the stadium sports venue lighting needs to be compared in multiple schemes. The lighting design of the stadium includes two aspects, namely whether it can meet the requirements of illumination standards and lighting quality. This is the main indicator for evaluating the lighting of a stadium.

1.1 Factors affecting stadium lighting
In order to ensure adequate illumination in the stadium, designers must consider the following factors:
1) Illuminance: In addition to ensuring the normal performance of the athletes, the reasonable illuminance of the referees ensures that the audience in front of the TV and the TV can watch the game comfortably. Different sports also require different illumination. The illuminance required for sports events, business activities, etc. is also different.
2) Illumination uniformity: The ratio of the minimum illuminance value to the maximum illuminance value is illuminance uniformity. Whether it is an indoor stadium or an open-air stadium, the requirements for lighting are very high. For example, in basketball courts, the middle ground often gathers more lights, but the areas with excessive illumination often produce glare, and the rebound area often The brightness of the light will be weak, ensuring the uniformity of the illumination of the overall venue, which plays a vital role in the level of the athletes.
3) Glare: Glare refers to the visual condition in the field of view due to unsuitable brightness distribution, or extreme brightness contrast in space or time, resulting in visual discomfort and reduced object visibility. There is a bright feeling in the field of vision that the human eye can't adapt, which has a great impact on the athletes, especially the ball sports. The athletes cannot accurately determine the ball landing point.

Connectors can be classified into three basic types: line to line, line to board and board to board. These three types of connections are not entirely different. There are two reasons for this type of overlap. First of all, the design of the same connector only needs to be redefined after slightly changing the connection mode, that is to say, it becomes a new design scheme that can be applied to another type of connection mode; secondly, a cable can be installed with a line to line connector at one end and a line to board connector at the other end during assembly, for example, the appearance of class 5 I / O connector is the most common one See for example. If we avoid the fuzziness of this kind of connection, it will provide an effective basis for connector classification.
