Suqian is a younger prefecture-level city. Before the city was built, although the city lighting has developed year by year, the lighting facilities are mostly simple functional facilities. The urban area is only a few street installations, and a few buildings have been simply illuminated. The urban lighting rate is very low, and the overall level and technology are not high. After the establishment of the city, with the continuous expansion of the construction scale, the urban lighting of Suqian City began to enter a stage of comprehensive development, especially since 2000, the city has been staging from urban lighting types, light sources, illuminators, power supply facilities, etc. The large-scale renovation of the lighting facilities in the old city was carried out in batches, and at the same time, many "light-free, lamp-free areas" were used to repair the lights. Especially in recent years, Suqian City has organized some large-scale activities, such as the Eco-Agriculture Fair, the Su Wine Festival, the five major environmental remediations, and the major festive festival celebrations as an opportunity to pay close attention to the construction of urban lighting projects, increase capital investment, and focus on The renovation of the Yellow River, the canal, and some of the lighting facilities in the city, have greatly improved the nightscape lighting in Suqian. At present, the existing landscape lighting in the urban area of ​​Suqian has increased to 9 times since the beginning of the city. In recent years, in order to vigorously promote the construction of urban lighting “lifting and upgrading†project, Suqian City strictly follows the work idea of ​​“street lights, squares and single building lighting as the main body, advertising, store lighting as the backdrop, trees and bridge lighting as embellishmentâ€. We will fully promote the construction of urban lighting projects, and further implement landscape lighting projects for more than 300 units on more than 20 main and secondary roads in the urban area. A total of more than 20,000 new lightings will be installed, and urban lighting will achieve “one road, one sceneâ€. Basically, a new pattern of landscape lighting with points, lines and sheets connected, high, medium and low staggered, dynamic and static, is used to brighten Suqian and beautify Suqian, so as to lay a foothold for Suqian's economy and lay a good investment environment. The existence of a solid foundation for the illumination of urban landscape lighting 1. The understanding of urban landscape lighting is not enough. In recent years, although most units and owners have improved their understanding of the importance of urban lighting, there are still some units that do not have enough knowledge of lighting work. Some believe that engaging in landscape lighting is a waste of money; some think it is In the flower racks, do surface articles, engage in formalism; some in order to cope with the installation of some simple lighting facilities; some units have installed landscape lighting facilities according to the standard requirements, but are not willing to turn on the lights as required; some units It only pays attention to the opening of festivals and major events, but ignores the usual lighting. Even some of the installed landscape lighting facilities are only placed and have not been used for many years; some units have been installed with lighting facilities that are in disrepair and facilities are old. Unbearable, severe damage, it is impossible to implement normal activation. Second, the urban landscape lighting management system is not sound enough. First, the separation mechanism for construction and maintenance is imperfect. Since the construction and maintenance are not the same department, some construction units of landscape lighting projects tend to ignore the reliability and convenience of the quality and maintenance of landscape lighting projects under the control of profit maximization, which brings many troubles to the maintenance of landscape lighting projects in the later period. Second, the street lamp maintenance guarantee mechanism is not in place. Due to the difficulty of municipal finance, the annual maintenance personnel funds and street lamp maintenance funds are much lower than the quota standards, which cannot meet the needs of normal maintenance of street lamps and restrict the healthy and coordinated development of urban lighting work in the city. Third, the construction of landscape lighting facilities is not standardized. For many years, the urban lighting construction in Suqian City has been regarded as a follow-up work. It is often considered after the completion of the construction project. Afterwards, it will be remedied, and it will be half the effort. At the same time, in the construction of urban landscape lighting facilities, it is not completely in accordance with the night lighting specifications. There are many landscape lighting. The final finalization of the project is based solely on the personal preference of the owner of the owner, and the design renderings alone, resulting in the construction of landscape lighting facilities are not rigorous, irregular, light pollution, and light disturbances. Fourth, re-establish light maintenance. The new construction of urban night lighting facilities is often a separate policy, blooming everywhere. Once completed, the owners and streetlight management departments will promote each other in maintenance and management, and the responsibilities are unclear. Moreover, the night lighting facilities of the parks and hotels are not uniform and can be opened at will. Turning off the lights, the lighting is destroyed, the phenomenon of not being repaired in time is very common, the lighting facilities are incomplete, and the phenomenon of "blinking lights" is more, which not only affects the image of the city, but also seriously hinders the improvement of the city's lighting level. Countermeasures to improve the level of landscape lighting 1. Further unify the thinking and effectively raise awareness of the importance of urban landscape lighting. In the process of accelerating urban modernization, we must examine the urban nightscape construction with new eyes and new standards, and recognize the importance of urban nighttime landscape to enhance the image of the city from a higher level, and strengthen the urgent need to grasp the urban lighting work. Feeling and consciousness. In view of the wide-ranging, policy-oriented and difficult work of urban lighting projects, all levels of the city must unify their thinking, unify the pace of action, and work together to create a "everyone cares about urban lighting and everyone supports the city." The good atmosphere of lighting and everyone involved in urban lighting. Second, according to urban characteristics and regional functions, the overall planning of urban lighting is prepared. The urban lighting master plan is the basic basis for the construction and management of urban lighting infrastructure, and is an important prerequisite and means for comprehensively exerting the social, environmental and economic benefits of urban lighting. Therefore, the construction of urban lighting should adhere to the principle of “comprehensive planning, scientific construction, and unified managementâ€. According to the nature of the city, rationally plan the urban lighting layout and properly locate the urban lighting style. Urban lighting should be based on single building lighting, road lighting as a line, key scenic spots and street night lighting as a breakthrough, forming a three-dimensional, multi-color, high-grade lighting system. Roads and sections of different functional areas of the city, specific environments and buildings should have different brightness requirements, and strive to create a warm, quiet and comfortable leisure environment. At the micro level, the illumination of each individual building should be achieved to the best effect; on the macro level, the effect of “shaped and scattered†is achieved to create a harmonious, beautiful and harmonious lighting atmosphere. Third, deepen the reform of the landscape lighting management system, and fundamentally solve the shortcomings of the current system. Construction is the basis and premise of management. Management is the continuation and development of construction and an important guarantee for maintaining the achievements of construction. For the management of landscape lighting facilities with a large area, it is necessary to establish the concept of social management, and the urban management department implements all-round dynamic management of socialization and marketization. It is necessary to further expand the terms of reference of the street lighting management organization, and give the street lighting management organization the responsibility for the construction of urban landscape lighting construction, landscape lighting facilities operation management, project construction quality monitoring, landscape lighting design project demonstration, landscape lighting construction bidding, etc., thereby effectively curbing The contradiction arises after the separation of construction and management. Fourth, the landscape lighting project and the construction project are designed synchronously, synchronized, and delivered simultaneously. In the future, large-scale buildings that are newly built, rebuilt or expanded should be considered together with the construction of landscape lighting, so that the project construction and night lighting can be planned, synchronized, synchronized, and delivered simultaneously. The lighting design of the building should be based on the theme of the district, according to the characteristics of the building, to form their own characteristics, to be willing to invest in planning and design, to hire high-level planning and design units to bid design, fully listen to the opinions of experts, scholars and the community, fully Argument. At the same time, it is necessary to further improve the quality and technological content of urban lighting projects, actively promote the application of new technologies, new products, and new art. It is necessary to strictly control all aspects of planning, design, approval, and construction, and effectively improve the construction and management level of lighting projects. . Fifth, establish a diversified investment mechanism to comprehensively promote the construction of urban landscape lighting projects. Urban landscape lighting projects are an integral part of urban infrastructure construction, and the necessary inputs are needed. Landscape lighting projects must adhere to the path of market-oriented operation, establish a multi-investment mechanism, and adopt multiple channels to raise funds. It is necessary to use the concept of operating a city, revitalize idle assets, auction advertising use rights, and encourage the use of lights to raise lights. For example, light box advertisements, through auctions and collecting rental fees, effectively compensate for the lack of construction funds, and strive to form a "light trick." The virtuous circle of customers, customers, and commercial lamps, strive to do more with less, do more things, and do good things. 6. Improve the scientific and technological content, promote the application of "three remote" automatic control technology. Urban landscape lighting engineering involves various lines All industries must implement unified management of existing and new landscape lighting projects, and must also use modern control technology for scientific management. It is necessary to establish a citywide city lighting control center as soon as possible to implement radio remote control management for all landscape lighting in the city. Using the "three remote" automatic control technology of telemetry, remote control and remote communication, the monitoring automation is implemented, and the functions of time switch, operation monitoring, measurement and measurement, fault display, etc. are mastered in an effort to improve the level of urban lighting.
