Compared with the picturesque scenery of the day, the night of Cangzhou has a touching sentiment. Street lamps are an essential element of this kind of sentiment. She is not only a lighting tool, but also a special carrier of urban culture. She is a witness and witness of the development of the city. Over the years, what kind of transformation has the street lamp in Chenzhou experienced? What is the current state of development? What kind of dilemma is it facing? Recently, the reporter conducted an investigation.
Design: blending with the overall style of the city, the first lamp of the city, the simple, yet modern and prosperous. As night falls, the transparent lantern-type 250-watt high-pressure sodium lamp will embellish the blue-brick wall of the brick wall, and the Wenqing Road that hangs the lattice window in the cloister is more elegant.
The street lamp was replaced with a quaint shape, and the Song Dynasty style of Wenqing Road Commercial Street was reflected from the details, which was consistent with the overall style. Zhong Hai, a citizen who has a deep understanding of the changes in Wenqing Road, said.
In Zhangzhou, the combination of street lamps and urban landscapes is more than this: the new street lamps in the streets and alleys, the charming landscape lights on the three banks of the Three Rivers, the magnificent aerial roses in the Golden Square, and the antique court lanterns in Songcheng Park. The night is even more graceful.
In order to realize the transition from street lighting to night lighting, the city's design of road lighting system, in addition to meeting the function of night lighting, creating a comfortable lighting environment, but also taking into account the effect of the day, let the street lamp play the role of beautifying the city. In recent years, all new roads and main roads in the downtown area have been created in accordance with the one-way, one-light, one-way and one-landscape standards.
The types of street lamps in Zhangzhou have also evolved from the single incandescent lamps and mercury lamps to the current garden lights, high-pressure sodium lamps, LED lamps and other light source types, with colorful rainbow lights and floodlights. During the day, the street lamps of different shapes show unique charms along the endless stream, adding a beautiful scenery to Luzhou. At night, the brilliance of the street lights will decorate the city with colorful, patchwork buildings that are more illuminated by various lamps. Beautiful, reflecting the vitality and infinite charm of Cangzhou's development.
Energy-saving: Green lighting has become a new development direction in Jianzhoumen pontoon dock in Zhangzhou. The reporter saw that two wind-energy complementary street lamps have been put into use. This new type of street light combined with wind power and solar power is the first application in the city's functional lighting. It is not only energy-saving and environmentally friendly, but also effective against theft.
The reporter learned from the street lamp management office of the Municipal Engineering Management Office of Cangzhou City that the street lamp department had installed several 1000-watt high-pressure sodium lamps at the Jianchunmen pontoon dock. The cable lines laid by the installation of street lamps were often accidentally stolen, resulting in street lights often blind. In order to ensure that the citizens pass through the pontoon safely during the night, the street lamp department decided to install the wind and solar energy-saving street lamps here.
At present, two 150-watt LED-type wind-solar complementary energy-saving street lamps of up to 10 meters stand on the shore of the pontoon, which can basically meet the lighting requirements of the Jianchunmen pontoon.
These street lamps also have solar panels and wind turbines. They can use solar power or wind power to generate electricity. Excess electric energy is stored in the battery. It does not need to be powered by power lines. It can save a lot of wires and electricity and avoid human beings. The phenomenon occurs, and it can ensure that the lights are illuminated for a long time at night, which is enough to overcome the problem of insufficient light in the southern rainy days. Xie Keqi, director of the Street Light Management Office of the Municipal Engineering Management Office, introduced.
In recent years, the street lamp energy-saving work has adhered to the principle of establishing emission reduction, paying attention to the development of the industry, rationally and steadily advancing, and vigorously tapping energy-saving resources. In the current LED street lights, there are still technical defects such as light decay, glare and high cost, and the principle of not blindly following the trend, paying attention to the development of the industry, and steadily testing and promoting, gradually advance.
At the same time, in order to reduce the energy consumption of street lamps in the downtown area as much as possible, under the premise of ensuring efficient lighting of street lamps, the city actively explores the scientific development road of energy conservation and emission reduction. On the basis of the complete elimination of incandescent lamps, LED lamps are gradually used to replace some of the high-energy aging and dilapidated high-pressure sodium lamps, and a combination lighting method is adopted, that is, energy saving is performed by means of a light interval or a bright side. At the same time, the city also installed energy-saving control terminals on the streetlights of the main sections of the downtown area to save energy.
In addition, the city plans to use more than 3.1 million yuan to invest in more than 3.1 million yuan to upgrade or renovate LED or solar streetlights in 103 small streets and lanes in downtown areas, and invest more than 5.6 million yuan to block other road trees to block road lighting, aging or high energy consumption. The street lamp was rebuilt, and it is planned to invest more than 610 million yuan to install the street lamp controller for the main and secondary trunk roads, and to renovate and perfect the street lamp control terminal.
According to statistics, through active energy-saving measures, the city's actual annual electricity saving has exceeded 4 million yuan. Green lighting with the goal of energy conservation and environmental protection has become a new direction for the development of Luzhou street lamps.
Management: New topics require new ideas for streetlights to provide convenience for urban life, as well as new topics for streetlight management, including repairs for streetlights, management and maintenance of streetlights, new and rebuilt streetlights, and streetlights. Protection and so on.
From more than 3,000 years ago to more than 20,000 baht, from overhead lines to buried lines, from aluminum cores to copper cores, from bulky cement rods to rugged, elegant stainless steel wires Rods, from ladder work to mechanized operations, from manual opening and closing to intelligent monitoring, from traditional high-energy street lamps to energy-saving lamps, from street lights with a lighting rate of less than 70 to staying above 99 in the first downtown area of ​​the province A historic transformation.
There is no doubt that the more development of street lamps, the more arduous and urgent the tasks and responsibilities of management and protection. The key to the development of the street lamp business is to ensure the coverage of street lamps, the integrity of facilities and the rate of lighting, and to strictly control the materials of the project. While meeting the lighting needs, we will continue to tap the potential of energy conservation and consumption reduction. Xie Keqi said.
In terms of the control of street lamps, the way of opening and closing street lamps that had the most headaches for street lamp managers has been well solved in recent years. In the Luzhou City Street Light Management Center, the reporter saw that the scientific opening and closing of the street lights in the entire downtown area was completed in this control room: as long as the equipment is turned on in the street lighting monitoring center, the controller will automatically follow the instructions. It can automatically open and close at the same time according to sunrise and sunset time, and can temporarily adjust the opening and closing according to the light, and monitor the street lamp fault at any time, find the line fault in time, automatically alarm, and change the passive management to active management. It has completely changed the traditional lighting system and the way of turning lights off and off.
The city center has the highest rate in the province. The actual maintenance cost of the single-street street lamp is counted down. With the continuous increase of the maintenance of street lamp facilities, the existing mechanical equipment is far from meeting the normal maintenance needs and has been seriously affected. The development of streetlight business in our city. In addition, the problem of cable theft is very serious. Since last year, many cables such as the west entrance and exit of Dongzhou and Dongjiangyuan Avenue have been stolen, causing direct economic losses of more than 200,000 yuan each year. Xie Keqi introduced: In response to the main problems restricting the development of street lamps, we are investigating and communicating with relevant departments on relevant issues. It is planned to form a special research report early next year, and strive to solve them one by one.
