Moderator: Just now you also mentioned the National Games. Now everyone is more concerned about South Africa's World Cup. I don't know if you can't watch football. You also said that when you were involved in lighting design for the Olympic Games, you were involved in sports lighting. What are the difficulties in designing this piece?
Zhan Qingxuan: Sports lighting refers not to the lighting of the stadium building facade, but to the lighting of the arena inside the stadium. This is very professional. Our country has also experienced a development stage. When our country opened the Asian Games in Beijing in the late 1980s The lighting of the Asian Games was based on the ground. The ground was bright, but the lighting on the vertical plane was not enough. In fact, watching sports matches was the same as watching performances. For the athletes, not only did they have no obstacles underground, they also needed to see Companion, there must be vertical lighting, the referee is also, the audience watching the game is not exciting, depends on people, so this vertical surface lighting requirements are high. In the past, overhead lighting was installed. Now, lighting is installed diagonally above the stadium, especially in the stadium. There are standing towers and belts. Especially in big stadiums, like the bird's nest, more than 300 spotlights. According to the uniform, this is not easy, this computer can not be counted, the unknown is too much, this depends on experience, computer-aided design, set the wattage to test, adjust, is such a process. This is not like an office building, generally not doing well, so like the international competition is mainly Philips lighting, they have a good relationship with the International Olympic Committee or FIFA, many sports lighting standards are set by them, Including the requirements for photography, video, color film, television have higher requirements, their professional requirements, do so.
As most of our domestic companies do Philips, there are also some domestic lighting companies to do, in general there are professional requirements, this requirement is very strict. In the past few years, the International Football Association brought an illumination meter to measure on the spot. If it fails to meet the standard, it will not allow the game.
Lighting is very critical in sports competitions. Before the Olympics started, the table tennis competitions at Peking University were completed. The lights were off for half an hour. The top leaders personally interrogated. You see little pressure on this matter. Beijing organized four professional electrical inspection teams to check the line with the Power Supply Bureau, check the design, check it for three months, and finally solved it. The Olympic Games can never be turned off. The lights are now high-powered metal lamps. , it will take a while to extinguish and restart, so it cannot be extinguished. The solution to the final solution is that site lighting is half of the electricity supply and half of the electricity is supplied by the generator. This is a very special case.
Landscape lighting is relatively easy. The lights like the opening ceremony of Zhang Yimou do not belong to the category of architectural lighting. The lighting of the opening ceremony of the Olympic Games is also very exciting. It is the contribution of design creativity and lighting equipment.
Moderator: In front of you also said that you went to the Shanghai World Expo. Can you talk about your feelings?
Zhan Qingxuan: This World Expo is the largest World Expo in history. It has a large scale and a lot of people. They have special evenings. They come in at twelve o'clock to see twelve. I just visited during the day and saw a little light after dark. The overall impression is very good, because there are LEDs now, LED is good as a landscape lighting, because it can be equipped with a variety of colors, it is very convenient to control and change light, so most of them are LED lights This kind of feeling is still very casual, color, light, is a very strong atmosphere of the holiday season.
There are some square lights in the park that also use LEDs, so I concluded that there is a lot of festive atmosphere. The Chinese pavilion is red, and the lights are particularly bright for a dozen. Some curved surfaces on the Expo Axis are white. Dyeing up is very beautiful, always feel very good, there are some elevated roads, viaducts, the following lighting is not very good handling, may be the relationship between rush, uneven surface, there are some defects in the location of the lights, but the overall environment Speaking is still quite good, I did not specifically watch night games.
Indoor lighting is not the main one. The main indoor ones are projection presentations. They are dynamic, and they are also very exciting. They are also the latest technologies. I only looked at the Spanish Pavilion, one building of Taipei City Construction and several urban transformation exhibition halls. Can not be partial to all.
Moderator: Because of the time, today's interview is here. Thank you, Professor Zhan.
Zhan Qingxuan: Thank you!
