In November 2018, the Aladdin Lamp Award Organizing Committee organized a special symposium with Changsha Local Society, Street Lamp Institute and Engineering Company. At the symposium, experts from the delegation discussed the concept of planning and design, the input and output of lighting, management and maintenance of Changsha's night scene construction from the past, present and future, and put forward many valuable suggestions. Let's hear what they say.
Director of Wuliang Changsha City Maintenance Quality Supervision Center
I think Changsha lacks innovation in night scene brightening. Innovation is a kind of adjustment, a kind of reform, providing policy services and public goods, so as to make the supply more quality. Because of the insufficient supply of Changsha, the urban night scenery is not commensurate with Changsha's urban positioning and development level, so Changsha's urban night scenery can be brightened more beautifully and the total amount can be increased. On the other hand, Changsha's management and supervision of night scene brightening is seriously absent. Shanghai, Shenzhen, Guangzhou and other cities have lighting administration bureaus or lighting administration offices, but Changsha has never had such institutions. Without such a full-time organization, there would be no fixed mechanism for departments and division of labor and cooperation. In addition, the degree of coordination and public participation in the construction process is not enough to stimulate the enthusiasm of social investment. Therefore, Changsha should attract more diversified investors to guide the development of night lighting through reasonable normative guidance and policy support. At the same time, we should interact with the citizens, listen to the government and win their opinions. Regarding the understanding of lighting and city, I think lighting is very important for building a city, or for shaping the image of a city.
The reason why a city is called a city is to some extent because there are lights at night. Lighting can increase the cultural characteristics of the city, promote economic development, agglomerate economic effects, and improve the safety index. It is unimaginable that a city without lights. This is also the harmonious growth of lighting and city, so that city lights focus more on people and city, more attention to people's feelings, experience and happiness, concern about the image and development of the city, excavate the laws that really conform to the development of the city.
In my opinion, the first-class urban governance is the combination of science, intelligence and humanity. Urban managers should be good at using modern scientific and technological means to create urban lighting, and should also have embroidery-like care, patience and caution to open up the last kilometer of urban services, so that policy humanistic care can be transmitted to every citizen of the city, including our lighting management should also be human. Sexualization, refinement, scientificalization and intellectualization require confidence, patience and perseverance. Through the joint participation and cooperation of market, design and management, the construction of Changsha Lighting will make a great contribution.

Changsha city night scene brightening, the older generation feel deeply, the current management issues have a great impact on the overall layout of Changsha. First, in the absence of planning, in the past, people only paid attention to the part and neglected the whole. What's the most important? Tendering and bidding problems, such as a 20 million mark can be divided into more than a dozen tenders, which will have a negative impact on the overall maintenance, management and maintenance of the future; Second, Changsha has been making city night scene brightening since 1999, with a large annual investment. Up to now, we have seen that the market changes have been changing materials, but the design methods and thinking are not much. Change. Changsha lacks protection for buildings. After lighting, it can be seen at night, but it is not wise to design the buildings with lights all over the walls during the day. For the overall development of Changsha, it belongs to development first and then management, which will certainly leave drawbacks in the future construction. If we can plan well in advance and reduce the number of lights on the premise of ensuring the quality, the later maintenance will be much better, and the economic optimization will be achieved in use and operation. And the street lamp is doing very well in Changsha. In terms of illumination and effect of functional lighting, Changsha has a standard and the pole type of street lamp is unified. However, in the application of new technologies, the application of LED street lamps in Changsha is still relatively small, and the promotion of new technologies should be actively promoted and strengthened.
Ren Weigong Secretary-General of Hunan Illumination Society
As a street lamp management department, Changsha really needs to develop LED, but in road construction, it is not immature technology, but now the products are mixed. There are 20,000 to 40,000 manufacturers of LED street lamp all over the country. There are several reasons why Changsha street lamp dares not use LED street lamp. First, the quality of products is uneven, which makes the purchasing units unable to supply high-quality products. In addition, the current national standards for products and street lamps are lack of specifications. If the products of manufacturer A are used, it is necessary to find him. Now the modular production of LED street lamps manufacturer can not interchange the modules of manufacturer and manufacturer, which brings great inconvenience to maintenance. So we can't say that the technology is immature and the products are not good, but now the products are uneven and there is no standard.

Changsha is a city of mountains and rivers. After so many years of batch development, Changsha has achieved certain results, highlighting its own cultural characteristics, but the shortcoming is that it has not formed a large-scale linkage mechanism, media show, and effective unified management. In case of major festivals, each district in Changsha has its own political Council to do some projects, but they are not uniform. For example, the cross-strait project of Changsha in 2017, Changsha Airport, including some main roads, we are all important participants in the construction of Xiangjiang New Area. It can be said that Changsha has invested more than 1 billion urban landscape lighting volume in recent years, but all of them are implemented in sub-areas and years, not as a whole to control, which from the overall coordination point of view, caused the effect of each region is not balanced. So Changsha is bright, but Changsha's night scenery is scattered, from a professional point of view, there are still many shortcomings. Changsha still needs a detonating point to use the light to drive its development. For example, Guangzhou Tower is a landmark building, which extends along the central axis to form an important commercial landscape belt. Changsha lacks a core landmark night scene gathering place. From the point of view of cultural tourism, Changsha should choose the most representative comprehensive area and make it more dazzling, so that it may be a point with a face. The new Wuyi Square creates a large underground space, gathering all the most fashionable, cutting-edge and trendy businesses in Changsha. If we can do some high-tech, breakthrough traditional cultural and tourism lighting or macro-effect, it can become a new trigger point and a distribution center attracting people in the future. It has such tourism value.

Changsha's urban night scene brightening projects from 2015 to 2018 are many. Bridge brightening projects on both sides of the river, airport highway and ancient urban areas have been done in recent years. However, the effect of the project on both sides of the river is not obvious, which must be acknowledged. The main project of both sides of the river is done by Tsinghua. Our planning institute cooperates with the later implementation part, so the signal control is far away, the effect is not in place, and the situation of disconnection appears, which makes people feel that there is no integrity and very scattered. Including Changsha City in 2017, there were many projects, such as Hunan-Jiangxi Road and Airport Avenue. At that time, the tender was more than 90 million, but in fact, more than 40 million projects were implemented, and several tender segments were also implemented. In addition, the 160 million projects of Shaoshan Road have been completed in the middle of the project, but they can not be finished in the back, and shrinkage has occurred. These winning projects have not been implemented. The main reason is that EPC is banned in the context of the Department of Construction. We have been greatly affected. The design has reduced the volume of business by at least half. I heard that two projects in Changsha County have been suspended indefinitely. All brightening projects are temporarily not implemented. These situations are mainly affected by the policy. Some time ago, I heard that the Department of Construction has issued a document prohibiting excessive beautification and brightening. Of course, excess is a common phenomenon nowadays.

Changsha is one of the first 24 famous historical and cultural cities in China, with a history of more than 2,000 years and a great number of talented people. But up to now, the foundation of the city has not changed, and the brand of Changsha's famous historical and cultural city may be reduced.
Not long ago, Yueyang, as a group of 24 famous cultural cities in Changsha, may be delisted. So is Changsha. The criterion is very simple. Do you have any historical details? Are there any real historical relics? Changsha is a cultural capital, but culture may be more concentrated on entertainment, catering and media, which are the carriers of modern culture, while for history and culture. Development may be relatively shallow in the dissemination and inheritance of Huxiang culture.
Why do you say that? First of all, in terms of cultural orientation, many leaders and decision makers, including citizens, do not know enough and think that culture does not make money, so it needs to play a game with the economy. In addition, in terms of cultural cognition, what kind of value does culture have? Or in the final analysis, what kind of culture should be maintained and what kind of culture should be abandoned are relatively shallow levels.
Specifically speaking, the lighting link, in fact, all designs should have cultural genes. This is the real high-end design, but there is no pure commercial design. The more culture and Commerce are, the higher the commercial value, the less culture, the worse the things are. This is a common sense. It is absolutely not a question that we can play games with each other. In addition, the lighting management, multi-head management is the most typical feature of Changsha, a complete project has been dismantled. As far as lighting is concerned, lighting covers all aspects, from technology to design, to management, it is necessary to gather expert teams to make lighting decision-making opinions for Changsha or any city in Hunan, rather than a departmental opinion. If our expert team is well established, with a comprehensive system of government, universities and enterprises, fully expressing their opinions, and finally making decisions, it should be scientific, complete and reasonable. Lighting will never be completed by all the planning and construction groups. Lighting planning will only begin. Lighting planning and architecture will not be separated, nor will everyone and every designer have their own unique ideas. Then let the leaders and independent decision-makers combine all the opinions of all people and make a mixed and compromise. Finally, we can draw a nondescript, neither falling to the ground nor falling to the ground. There is no forward-looking conclusion.
So one is to attach importance to culture and the other is to make management decisions fairly and scientifically. If we grasp these two points, the government should take the lead, provide the support of managerial talents, universities and scientific research institutions to provide theoretical and ideological help, and enterprises to provide technical support and help, then our decision-making system should be a scientific system.

Why should we combine night scene lighting planning with urban design? Because the city night scene has a carrier, the most important carrier is architecture, building space lighting, there is a general spatial form. So when we do the overall planning of night scenery, if we remove the functional level of things, then the whole space should be built from the urban design, the urban landscape space system, as far as Changsha is the Shanshuizhou City, when doing night scenery, Shanshuizhou City must be its most basic geographical characteristics. What is the relationship between the night economy and the development of urban night scenery? Is it due to the light or the gradual growth of the light led by the development of the economy itself? Now we may develop a large-scale lighting economy, such as large-scale media animation, but in fact, in many cities, small space, it may be more not the economy of light production, more because of. Economic development needs lighting. Then talk about foreign countries, Europe and the United States probably in the 1960s and 1970s, their lighting is the most brilliant, but now we go to see their lighting facilities, not as brilliant as before, they will think more about the ecological protection of lighting. For example, high-rise lights can cause birds to crash, affect the insect's guidance system, make it feel disordered and cause death. Finally, the control of glare, now designers tend to handle in place, but may eventually be out of shape in the implementation, so from planning to implementation, every basic link can not be less, especially the details of the inspection.

From the perspective of provincial capitals, Changsha's night scenery is relatively scattered. Xiangjiang River is made by us and Junze Lighting. It is relatively centralized. Others are divided into six or seven sections without unified planning. Some of the large-scale centralized projects are under the responsibility of the city administration, others are under the responsibility of the construction unit, the bridge is under the responsibility of the district, and the city is assigned to a certain district. If we can do some large-scale projects, or centralize these scattered projects together to control, it may have a much better effect on the whole night scene brightening in Changsha. Now Changsha is bright, but the light here and there does not reflect the collective light. Moreover, Changsha's multi-head management has a great impact on the lighting effect of the whole city, leading consciousness easily affects the design; the design is inconsistent with the actual effect, this situation is also a headache; and Changsha's lights are better than two or three months, always not lit here, there have to be repaired, so we need more suggestions.

As the capital city of Changsha, we should make good preparations for future large-scale conferences. Wuhan, Zhengzhou and Jiangxi Province have come to our front. Then we are known as the strong province in the central region. Our total economic output is also the first few among the six provinces in the central region. What is our city orientation now? We should strive for a new life in the central city. But our real city does not match the central city of our country. How do we match? Every lighting person here should think about it. So no matter from the policy industry, economic strength, lighting manufacturers, administrative levels, we have to be prepared. If one day the opportunity comes, Hunan has large-scale project opportunities. When we have no plan, no opportunity to participate in urban construction in Hunan, this is the embarrassment of Hunan lighting. Since we agree that the deeper and more cultured things are to be embodied on a specific level, then culture must need things to carry, and without things to carry, it is air. If Hunan people don't understand their own culture, we need to invite a tall team from outside to help us understand. The result is that the interpretation is wrong. When we become the laughing stock of the world, the problem will be difficult to solve.
