Construction of the urban landscape lighting, the problems and tendencies

Urban landscape lighting at night (the urban landscape lighting), CIE94 document using the name \Urban Landscape lighting is lighting the important part of the city. Urban landscape lighting is to reshape the urban landscape with night-light image refers to its meaning is addition to the stadium, site and outdoor security lighting outdoor activities outside the space or landscape landscape lighting at night. It is a city of social progress, economic development, an important manifestation of the style characteristics. Some of the world night in some cities in developed countries like the sea of lights, lighting requirements, artistic, cultural taste are high; night construction from scratch in developing countries, developing very rapidly. 1 development of China's urban landscape lighting review since the founding of New China, China's urban construction in the growing landscape lighting, but the more concentrated the construction of large-scale urban landscape lighting project or start from the Bund and Shanghai in 1989 Nanjing Road, began after the construction landscape lighting. More than a decade,[link widoczny dla zalogowanych], Beijing, Tianjin, Chongqing, Guangzhou, Shenzhen, Dalian, Nanjing, Qingdao, Kunming, Chengdu, Xi'an, Yinchuan, Lanzhou, Urumqi and many other cities of varying size are the landscape lighting projects. Construction of urban night attracted domestic and foreign community, especially the urban construction and lighting workers are highly valued. Urban landscape lighting construction with remarkable results. It not only changed the image of the city at night to improve visibility and reputation of the city, but also extend and expand the activities of citizens and tourists at night time and space, to enrich their nightlife, driving at night on the economy, promote business, services and tourism development of the industry are of great significance and far-reaching impact. By some representative survey of urban landscape lighting, landscape lighting,[link widoczny dla zalogowanych], and in recent years, many cities experience of academic conferences and international exchange of trend analysis of urban landscape lighting, landscape lighting in the city felt the construction of the process there have been no planning or as planning later, the blind development, another to light, than the scale, and even some glass wall building has high-power flood light exposure, resulting in waste of energy, resulting in light pollution; other lighting methods a single, identical with each other, lack of features and a very fine night few other issues. To sum up experiences, lessons learned, and solve the problems in the development process to achieve continuous construction of the urban landscape lighting, the development of science forward, the paper landscape lighting in the building of positive results, the focus on the problems and tend to be about points Chuqian the views of leaders and colleagues for references, ask inappropriate criticism of correction. 2 urban landscape lighting should pay attention to the problems and tendencies should pay attention to the problem 2.1 investigation indicated that the process of building China's urban landscape lighting, the following issues deserve special attention. 2.1.1 Programming night surveyed the city from view, except for a few cities, most of the city's landscape lighting behind the lack of unified planning or planning. Even with planning, Congress has not passed through the city to become a legal document performance. Therefore, the current situation of the urban landscape lighting, landscape lighting unit is basically the act of spontaneous, their worth, so there is not the bright light, bright but should not be very bright, the night view of the entire city spread disorder, there is no primary and secondary and features , the overall effect of poor lighting. In terms of urban landscape lighting, landscape lighting of the city planning is to ensure the overall effectiveness of the urban landscape lighting key. Hope that the relevant government departments, the city lighting, landscape lighting and urban functions integrated into one, unified planning for urban lighting,[link widoczny dla zalogowanych], and as the overall urban planning in special planning, a role as a legal document to guide the construction of the urban landscape lighting . 2.1.2 mutual competition, mistaken night, the brighter the better question many cities in China is currently in the design of landscape lighting, illumination lighting requirements of many users or increasing the brightness, there you construction light I brighter than you, your lights and more lights than you I am more obvious trend of mutual competition, but also significant development and the rising trend. Measured from the survey data, average intensity of the surface of individual buildings was more than 500lx, building facade of electricity per square meter, up to 25W/m2 much, there really is Floodlighting, like the flood of red light shines on the facade, and almost are cast light from the front, so I saw a bright facade, building three-dimensional, wall color and texture of many advanced materials, are difficult to decorate identification, lighting effects even more impossible. Instead, the lighting equipment increased tariff charges electricity, lighting, glare, light pollution is a big problem, highlighted the negative effects of lighting. China in 2003, large areas of many cities in the south of the phenomenon of power cuts, shows that China has a shortage of electrical energy, even to the power supply is sufficient, in the process of building the landscape lighting should also pay great attention to energy conservation, remember \Landscape lighting is not the more light the better. \light phenomena. Evaluation of quality of a city landscape lighting, lighting is not the size the bigger the better, that Zhaoming attractions or 建筑 do not have to many, the key is to see whether it can reflect the characteristics of the city's image. For example, people say good night the city of Paris, in fact, is one of the few, but it can reflect the characteristics of the Eiffel Tower in Paris,[link widoczny dla zalogowanych], old and new Arc de Triomphe, the Louvre, the Champs Elysees and the beautiful night view of the Seine. Indeed truly reflect the characteristics of a city building human and natural landscape, structures and attractions are not many. Therefore, in the planning and construction of urban landscape lighting, the emphasis on respect for the personality of the city, highlighting the characteristics of the city, from the actual situation of the city, through the depth investigations and studies, to seize the building reflects the characteristics of the city, structures and sites for lighting, landscape lighting to prevent the better building or attraction, it seems that the phenomenon of a building must be lit. 2.1.4 Urban Landscape lighting methods before the reform and opening up, China's urban landscape lighting, landscape lighting, such as building outline lights are used almost exclusively for lighting, commercial street lighting, landscape lighting, neon is used Other methods, such as lighting, flood lighting, interior lighting, light, light box, lighting and other special lighting methods are rarely used. After the reforms, especially in recent years, urban landscape lighting of buildings and almost all use a single floodlight way, mistakenly believe that flood lighting landscape lighting is only one way. The lighting is rarely used other ways, and many buildings shone clear though, but the lack of lighting levels, three-dimensional difference,[link widoczny dla zalogowanych], the overall effect of poor lighting. And glass curtain wall construction methods of landscape lighting, and many places do not take into account the characteristics of the glass curtain wall, when in landscape lighting design uses high power floodlights lighting, the result is a waste of a lot of power, and should not receive lighting effects, or the dark glass curtain wall; the contrary, the indoor floodlights shone clear, light pollution, which seriously interfere with the work and rest room, in need of special attention. 2.1.5 the application of colored light colored light in the architectural landscape lighting application problems in the International Commission on Illumination (CIE) has repeatedly stressed that the technical paper should be cautious about. One reason is the color of light has a strong emotional; Second, the technical issues involved and influenced by many factors. If used improperly, tend to distort the architectural image, reduce or even destruction of architectural landscape lighting effects. In China the rise and development of landscape lighting is the time stressed that the issue is useful. However, many buildings in China have been used in landscape lighting, colored light, and more confusion, especially in some small city's buildings and landscape lighting, red and green, with the architectural style, function, and environmental characteristics of the wall color is very coordinated lighting are also many instances. This should arouse our attention and attention.
