The 2016 Holy Fire of the Rio Summer Games has just been extinguished. We seem to have heard the footsteps of the 2018 PyeongChang Winter Olympics, and the 2022 Beijing Winter Olympics is getting closer and closer. What are the characteristics of the Winter Olympics' ice and snow sports program? Today I want to systematically explain the issues that are of general concern to this sports lighting practitioner. Winter Olympics history and overview Since the 1st Winter Olympics in Chamonix, France (initially the “Winter Sports Weekâ€) in 1924, the Winter Olympics has been successfully held for 22 sessions. The hosting of the Winter Olympics requires strong economic strength as a support. The following picture shows the countries that have hosted the Winter Olympics (where the blue is a country that has been held at least twice). After years of development, the current Winter Olympic Games competition has two items, including biathlon, snowmobile, curling, ice hockey, sledding, skating and skiing, with 15 points, while the small items are more than 100. The number of items in previous Winter Olympics is as follows: The international single sports organizations of the Winter Project include the International Skating Federation, the International Ski Federation, the International Ice Hockey Federation, the World Curling Federation, the International Biathlon Union, the International Association of Learning Cars and the International Sled Federation. Winter Olympics skating project design and characteristics There are more small items in the winter project, and the points are finer. Take skating as an example, the competition items are set as shown in the following table: Among them, speed skating is the oldest and most widely carried out project in ice sports. As early as the 18th century, the United Kingdom began to hold speed skating competitions. In 1889, the world championship was held for the first time in the Netherlands. The male and female speed skating were listed as the Winter Olympics in 1924 and 1960 respectively, with a total of 14 items. Speed ​​skating All competitions were conducted on a 400-meter-long runway, and the players glided counterclockwise. The runway is divided into two inner and outer lanes. The inner ring radius of the inner runway is 25 meters to 26 meters, and the inner ring radius of the outer runway is 29 meters to 30 meters. The athletes must exchange 1 runway for each slide (except for collective departure). The short track speed skating site is 60 meters long and 30 meters wide. The site is surrounded by a protective pad with a thickness of not less than 60 cm. The track is 111.12 meters long and is divided into straight roads and curved roads. The straight roads on both sides are 57.71 meters long and 7 meters wide. The curved roads on both sides are 53.41 meters long. The curves are composed of 7 marking blocks. The corners of the curve are to the protection mat. Not less than 4 meters away. Short track speed skating site Figure skating is performed at a standard ice hockey rink of 30 x 60 meters. Ice temperature: best -4 ° C, the maximum does not exceed -3 ° C, the lowest is not lower than -5 ° C. Ice thickness: best 5.5-6cm, minimum 4.5cm. The single organization has lower requirements for skating site lighting, the minimum illumination is 1400lx, the color temperature is uniform, and these lights should be evenly distributed throughout the ice and athletes. Lighting should also meet the requirements of color TV broadcast. The relevant standards have been described in detail in China's "Sports Hall Lighting Design and Testing Standards", and will not be repeated here.
