Under the guidance of the scientific concept of development, urban lighting has become more and more concerned by people, and it has achieved unprecedented development and improvement, which not only expands the urban space category, but also shows a city with its individualized historical culture and natural features. To enhance the taste of urban residents. Reshaping and beautifying the city's nighttime image through urban streetlights, improving the investment environment and living environment, and promoting the prosperity and development of urban commerce and tourism, bringing huge economic and social benefits to the city. Zhuhai streetlights witnessed the development of the SAR. In recent years, it has undergone several qualitative leap: from the early days of the 1980s, several fishermen’s lights, to today’s bustling, brightly lit and straight tarmac; from less than 40,000 street lamps in 1999 Up to now, more than 80,000 street lamps have grown by 100%. However, no matter how it develops, in addition to meeting the lighting requirements, we must require that it be energy efficient and environmentally friendly. Especially today, China's energy is still quite scarce. It is even more necessary to design a lighting scheme that meets the requirements of road lighting and saves electricity and is environmentally friendly. In recent years, the design, construction, construction and management of urban lighting projects in Zhuhai have contrasted with the development of surrounding cities. Relatively stagnant.
1. Problems in urban road lighting design
Zhuhai is a city full of romance and green ecological civilization. However, in the design process, street lamps are difficult to reflect the corresponding solutions. The main reasons are as follows:
1.1 Lighting design is not forward-looking
Under the premise of economy, practicality and beauty, but to reflect the combination of ornamental value and the overall environment, we must first achieve the purpose of “lighting upâ€. The sidewalks on both sides of Zhuhai Road are filled with various small trees, two years later. The tree has become a big tree and a tree, and the problem can be solved: the tree is taller than the lamp, the shade obscures the light, and the ground illumination is not enough. Later, it is transferred to the management and maintenance unit and it needs to be transformed. Resources have increased government fiscal expenditures. This phenomenon indicates that it is essential to develop a scientific and rational urban lighting special plan.
1.2 Product quality has no brand effect
The street lamp that newly installs or renovates a road should reflect the taste of a city. The key lies in the brand effect. People often talk about "the street lamp is not very simple. A pole, a lamp and a wire are energized to light up." That's right, but it's not easy to do it well and be beautiful. The following is an example of the decline of the luminous flux of a high-pressure sodium lamp source: Why is the street lamp in Zhuhai just after installation, the light is very bright, beautiful, and the illumination is also up to standard. After one year, the illumination will not meet the design requirements. The main reason is the lampshade. The sealing performance is not up to IP65, the ash on the transparent cover, the short life of the light source, and the serious attenuation of the luminous flux, etc., the quality of the product determines the effect of road lighting.
1.3 Lighting design is weak in energy conservation
In the road lighting design of Zhuhai, only how to achieve the lighting effect is considered, and the energy-saving awareness is weak. For example: the South Bay interchange last year was designed and installed with 1378 street lights, and one horizontal street lamp set with 18 lights. Each base double-lighted lamp double light source (400W+250W+2*LED) has 6 lights, each base double The power of the lamp is 1300W, and there are up to 8 kinds of lamp types and specifications (inconvenient maintenance). In the latter half of the night, there is no design for the midnight light, and the street lamp electricity cost is 100,000 yuan per month, and the road illumination is 37.1lx, giving the impression. It causes a kind of light pollution and energy waste, which is contrary to the purpose of building a conservation-oriented society in China.
2. Problems in urban road lighting construction and construction
As a government investment project, whether it is the owner or the owner, it is representative of the government's behavior. How to make the construction work scientific and reasonable, economic efficiency, standard and standard, fair and reasonable, professional management is essential.
2.1 A large number of illegal operations in the construction market have been repeatedly banned. The fierce vicious competition has caused tremendous pressure on the construction units, so that they have to sacrifice their own economic interests in order to survive, and operate in violation of regulations: bidding, calling, etc.; the behavior of the owners is not standardized, not professional, management Disorderly, the project is forcibly launched, and the construction unit should be responsible for contracting and arrears of construction funds, etc., and a huge black hole with economic risks. How to fill this black hole, the construction unit can only smash in the construction cost, which must result in the bean curd residue project. Leave a hidden danger to the maintenance unit that took over.
2.2 The development of intermediary organizations is not perfect, the social service capacity is insufficient, the supervision departments do not act, etc., but how do the projects go through each other? This explains from some aspects that there are some regulatory and institutional loopholes in project management. How to regulate the market is subject to the soundness of relevant laws and regulations in the industry.
2.3 The city needs to develop, the people's livelihood project must be launched, and the construction needs to rely on construction. The construction of street lamps requires a highly professional team, instead of bidding and bidding with Zhuhai in the past few years, that is, construction general contracting, building a house. The streetlights will be installed in the paving and decoration teams, etc. How can I build a streetlight project?
