Chengdu completed the transformation of more than 100,000 LED light poles

It is understood that in order to match the various lighting management and maintenance needs in the main urban area of Chengdu, the Chengdu Lighting Internet of Things Big Data Center came into being. The platform can actively and accurately identify street lamp failure types, equipment identification, GIS geographic location, and other information. After receiving the fault information, the platform will classify the algorithm according to the road section, safety hazard, and fault category, dispatch it to the front-line maintenance personnel in the form of a work order, and collect and archive maintenance results to form efficient closed-loop management.

Chengdu completed the transformation of more than 100,000 LED light poles

“Giving ID cards to street lamps is not just as simple as pasting signs,” said the relevant person in charge of the platform. Location and other information give each main light pole a unique identity, and through digital twins, the light poles can truly ‘live’ with us in the streets and alleys of Chengdu.”

Up to now, more than 100,000 light poles have been transformed, more than 100,000 single light controllers have been installed, and more than 800 smart monitoring boxes have been replaced, so that all light poles with certificates can be connected to the “network”.

It is an “ID card” and a “medical insurance card”, and the street lamp can also be “registered” automatically.

After taking out the mobile phone to scan the QR code on the “ID card” of the street lamp, you can enter the “diagnosis” page of the lamp post – Chengdu Street Lamp Repair WeChat applet, which records basic information such as the number of the lamp post and the road where it is located.

“Citizens encounter street lamp failures in their lives, and can locate the faulty light pole by scanning the code. If the QR code cannot be scanned due to contamination or missing, they can also locate and report the fault through the small maintenance program. Compared with the traditional telephone fault reporting and repair applets can help us locate the fault point more accurately and quickly.” said the staff of Chengdu Lighting Internet of Things Big Data Center.

The staff member said that the front-line lighting operation and maintenance personnel are like “doctors” who specialize in the field of urban lighting. Every day they will carry out systematic inspections according to the plan, and the lighting problems they find and solve will also form a part of the city. Lighting “medical records”, according to the characteristics of these diseases, the lighting Internet of Things big data center will continue to optimize the daily inspection plan, forming a closed loop of inspection “diagnosis and treatment”.

The light pole transformation work completed before is also particularly important at this time. A variety of intelligent diagnosis and treatment equipment, including single-light controllers, intelligent monitoring boxes, and water-logging monitoring sensors, have been transformed and constructed to replace manual inspections. The networked big data center alarms, and generates a “registration list” according to the pre-configured alarm algorithm or through manual assignment, and automatically dispatches the front-line personnel to go for maintenance. When the equipment maintenance is completed, the system alarm recovers, forming a closed loop of intelligent perception and fault reporting.

Municipal lighting in Huishan District, Wuxi, Jiangsu

Street lights are dots of “starlight” that light up the night sky of the city, illuminating the road for citizens to travel safely at night.

Municipal lighting in Huishan District, Wuxi, Jiangsu

In recent years, with the development of urban and rural construction in Huishan District and the continuous improvement of the traffic road network, the mileage of urban roads in Huishan District, Wuxi City, Jiangsu Province has increased by leaps and bounds, and the energy consumption of street lamps has increased year by year. According to statistics, Huishan District currently has more than 45,000 municipal lighting street lamps, but more than 35,000 of them are still using high-pressure sodium lamps. There are problems such as unreasonable energy consumption, imprecise management, and low urban lighting level.

Since 2022, in order to systematically improve the status quo of municipal lighting, Huishan District has been based on the long-term, focused on the future, promoted high-quality development with firm reforms, and initiated the implementation of contract energy management for municipal lighting facilities in the district.

What are the aspects of contract energy management for lighting facilities?

1. LED Energy Saving Transformation

It is planned to use 2-3 years to invest 87 million yuan to carry out LED transformation and single-lamp controller installation for 35,000 municipal lighting street lights. “The application proportion and power saving rate are higher than the city’s level.

2. Lighting intelligent supervision

Utilizing mature technologies such as GIS and Sanyao, an intelligent supervision platform for municipal lighting facilities in the whole district is simultaneously established to realize “one-network unified management” of lighting facilities in districts, towns (streets), and villages (communities), and to realize the dynamic grasp of information by district authorities and Intervention management and assessment.

3. Adjust the management system

The lighting facilities after the energy-saving transformation will be fully taken over by the District State Control Group, which will unify the management and maintenance entities at all levels, making the scientific and technological means, personnel technology, mechanical equipment and other aspects highly specialized, and strive to build a professional municipal lighting maintenance team based in Huishan.

Benefits of energy management contracts

It is reported that contract energy management can not only solve a series of software and hardware problems in the municipal lighting industry in our district, but also produce obvious economic benefits. According to preliminary estimates, after the energy-saving transformation is completed, 160 million kilowatts of electricity can be saved in ten years During the ten-year contract period, it is estimated that the government will save 112 million yuan in electricity bills, and the electricity energy-saving benefits generated will be distributed by the district-level finance and the State Control Group in a certain proportion. Public lighting resources such as street light poles will also be deeply tapped by the State Control Group. The potential value is used to feed back the development of the municipal lighting industry in the whole region, and then realize the healthy development of the municipal lighting industry.

At 8:00 p.m. on April 18, 120 sets of brand-new street lights on Wenquan Avenue and Huancheng North Road, Fang County, Shiyan City, Hubei Province began to shine in the night. state.

Hubei Wenquan Avenue, Huancheng North Road lighting project trial lights

The construction of road and street lighting facilities such as Wenquan Avenue and Huancheng North Road is a key project of the Fangxian government in 2023. It is also an important livelihood project to build a “4A” scenic county town, comprehensively improve the external image of Fangxian, and promote the development of the night economy in the central city.

As the traffic artery connecting several towns in the east, Wenquan Avenue plans to install 206 sets of double-pole and double-arm street lights and lay 6,000 meters of street light cables. Huancheng North Road has a total length of 6 kilometers. It is planned to install 255 sets of street lights and lay 12,000 meters of cables.

During the construction process, the Urban Management and Law Enforcement Bureau, in accordance with the requirements of the Fangxian County Party Committee and the County Government, urged the construction unit to seize the progress of the project, pay close attention to the quality of the project, and carry out the lighting renovation construction in strict accordance with the requirements of the design plan. Currently, the installation progress of the street lights on the two roads It has reached 80% of the total amount of the project. Next, the Fangxian Urban Management and Law Enforcement Bureau will go all out to organize the equipment and personnel, accelerate the project construction, and ensure that the lighting project is completed on schedule and with high quality.

Dalian Bay Submarine Tunnel Lighting System Lights Up

Recently, after 120 consecutive days of high-intensity fighting, the lighting system of the first cross-sea immersed tube tunnel in the high-latitude cold region of my country has been completely installed and debugged, and the interior of this submarine “giant dragon” has been fully lit.

Dalian Bay Submarine Tunnel Lighting System Lights Up

As a high-tech submarine lighting system, the artificial intelligence lighting of the Dalian Bay Submarine Tunnel in Dalian City, Liaoning Province can achieve harmony and unity with natural light, and can “feel” cloudy, sunny, cold, and warm, night and day – can adapt to the light perception of the four seasons change, timely adjust the color temperature and color difference between the seabed and the land area; adjust the brightness of the seabed light in time according to different weather such as sunny, cloudy, rainy, snowy, foggy, etc., as well as different light intensities such as morning, evening, daytime, and nighttime “High EQ” two-in-one.

To light up such a huge “dragon” on the seabed, there are many types of lighting that need to be set up – basic lighting in the middle section of the main line of the tunnel/ramp, emergency lighting, enhanced lighting at entrances and exits, lighting for awnings, passage lighting, and lighting in equipment rooms etc.; there are more than 10,000 sets of lighting fixtures alone, and the total length of the laid circuit is nearly 420,000 meters, involving nearly 180,000 meters of power pipelines, and nearly 10,000 sets of hangers…

At the same time, a strong power supply system is also required to support one lighting power distribution room and emergency lighting power supply room are respectively set up in the north bank equipment area of the tunnel, the south bank equipment area (1), and the south bank equipment area (2). Install 2 lighting equipment platforms. The lighting distribution room is equipped with a lighting distribution cabinet, an intelligent lighting control cabinet, and a lighting distribution box in the equipment area. The emergency lighting power supply room is equipped with a centralized emergency power supply device and a type A emergency lighting centralized power supply. A 10kV/ 0.4kV buried transformer for lighting, lighting distribution cabinet, intelligent lighting control cabinet, centralized emergency power supply device, and A-type emergency lighting centralized power supply.

Such a complicated submarine lighting system installation project is faced with difficulties such as time constraints, heavy tasks, and cross-operations. Especially for the lighting installation of the arc section of the submarine tunnel, it is necessary to convert the distance of the center line of the road into the distance of the inner arc and the outer arc before construction. , In addition, the installation of lamps and lanterns is a high-altitude operation, which is more dangerous. The Dalian Bay Submarine Tunnel Electromechanical Team of the China Communications First Harbor Engineering Co., Ltd.’s installation company faced difficulties head-on and took measures such as advanced layout, process coordination, and precise debugging to ensure quality and quality with the construction rhythm of “all-weather operations” such as non-stop holidays and shifts during the day and night. Quantitatively promote the construction progress. In the end, the important project node of lighting installation and commissioning for the entire tunnel was successfully realized.

This submarine “dragon” was successfully lit up, marking another crucial step towards the goal of opening the Dalian Bay Submarine Tunnel on time.

More than 220,000 street lights in Tainan City were replaced with LED lights

Tainan City is divided into 3 districts to install LED street lights. At present, about 10,200 street lights in Xibei, the third district, are actively replacing. It is expected to complete more than 220,000 streetlights in the city as early as the end of June. Save 60% of electricity consumption and reduce carbon emissions by 50,000 tons. According to the Public Works Bureau, LED lamps are energy-efficient, brighter, and have a lower failure rate than traditional street lamps. They can save the city about 95 million yuan in electricity bills each year, and they have a 9-year warranty.

More than 220,000 street lights in Tainan City were replaced with LED lights

According to the Public Works Bureau, Nanshi’s street lamps have replaced old energy-consuming sodium lamps with LED lamps. After the “Project Plan for Expanding the Installation of LED Street Lights” in 2013 and the “Sunset Project for Mercury Street Lights” in 2016, it will continue from December 2021 to Execute the “Tainan City Replacement LED Street Lighting Construction Project” to replace the remaining about 100,000 old energy-consuming sodium gas lamps and fluorescent lamps with LED lamps. The total cost is about 885 million yuan, and it is divided into three areas. At present, about 70,000 LED street lights in Districts 1 and 2 have been replaced with LED street lights, and there are still more than 10,200 street lights in Xibei District 3 that are actively being refitted.

Mayor Huang Weizhe said that the construction and management of street lamps is an important basis for providing citizens with a safer living environment. With the replacement of LED street lamps, not only electricity bills can be saved, but also energy saving and carbon reduction can be achieved. In addition, through intelligent Monitor the status of street lights in real-time, and save administrative procedures and maintenance costs at the same time. In the past, street lamps used more power-consuming sodium gas lamps. Because the operating temperature was as high as 400 degrees, a lot of energy was wasted due to high heat. After years of hard work by the Nanshi government, Datainan street lamps will soon be able to fully use LED lamps.

According to the Public Works Bureau, in addition to replacing the old energy-consuming sodium gas lamps, the construction project of LED street lamps in Tainan City also built the “Tainan Smart Street Lighting Management System” with new technological functions, among which 10,000 smart street lights will be automatically detected, and if there is an abnormal situation, they can automatically report for repairs, which can shorten the repair time for lamp failures and ensure the safety of passers-by.

Recently, the “Golden Land Xinhua Road” commercial office space project located on the west side of Shangsheng Xinsuo, Xinhua Road Street, was completed and opened. Since the start of construction, the District Greening and City Appearance Bureau’s Lighting Division has maintained linkage with businesses, actively doing a good job in the review and acceptance of lighting projects, and further exerting the role of “cohesion” in cohesion, service, and empowerment.

Xinhua Road is a long building with a total length of nearly 200 meters. The design style reveals minimalist aesthetics, and the thick stone on the facade creates a sense of time imprint.

When the lights come on, the lights of Xinhua Road are quiet, elegant, stable and grand. The overall building is presented in 3000K warm colors, blending in with the surrounding environment. The RGBW dimming and color changing system is turned on on weekends and holidays to increase the leisure atmosphere, which complements Shangsheng Xinsuo. The west facade of the building faces the residential buildings. In order to reduce the impact on the surrounding residents, lighting methods such as internal light transmission, slit lighting, window frame and overhanging lighting are mainly used to enhance the sense of three-dimensionality and lines.

Zhoupu Xieyang Culture and Leisure Corridor

Zhoupu Xieyang Cultural and Leisure Corridor is located at Lane 185, Quankou Road, Xinjing Town. It is a beautiful neighborhood with a miniature of old Shanghai and historical and cultural heritage. The night view of Zhoupu Xieyang enriches the urban slow traffic system, is an organic unity of living space, cultural space, and ecological space, and is a continuation of the beautiful scenery of Xinjing Town. Last year, the District Landscape Institute carefully organized maintenance units to comprehensively update the landscape lighting of Zhoupu Xieyang through the mode of maintenance and construction through landscape lighting.

Through the construction of landscape lighting, the cultural landscape wall and corridors are clearly layered, and people can feel the “past and present” of Xinjing Town on the landscape wall while strolling in the natural and comfortable night scene.

The image building of Zhoupu Xieyang has “Jiangnan rhyme”. Landscape lights with different color temperatures are randomly interspersed, which not only satisfies functional lighting, but also awakens the vitality of the building at night.

Along the walls of Jiangnan-style residences, the figure sculptures are designed vividly, adding to the fun of the space. Through the projection of lights, the humanistic life atmosphere in the regional environment can be better highlighted, and it has become a scenic spot for people to stop and watch.

The antique door shape, through the blessing of lights, uses the most natural method to highlight its three-dimensional effect, and the beautiful outline of the ancient building is clearly presented at night.

The landscape corridor at night not only satisfies practical and functional lighting, but also satisfies the creation of a comfortable and comfortable night environment atmosphere, providing surrounding residents with a public space for interaction and communication at night.

The orderly array of transparent and concise small light boxes on the cultural wall displays artworks and peasant paintings of various shapes, which not only play a role in promoting classic culture, but also make the entire wall come alive. The reporter learned that at present, the first phase of Zhoujiabang waterfront public space is being renovated and upgraded, and will be reopened to the public after the renovation is completed.

The lighting improvement project on both sides of the Jinjiang and Luoyang Rivers in Quanzhou is fully lit

As night falls and the lights come on, along the coastline of “Two Rivers and One Bay”, several landmark buildings simultaneously turn on the “Light Show”, and the prosperity and tranquility collide to create a bright night scene. On the eve of the May Day holiday, the lighting improvement projects on both sides of the Jinjiang and Luoyang Rivers in Quanzhou, Fujian were fully lit, continuously improving the city’s appearance and quality, and becoming the city’s new business card.


Dress up the “two rivers and two banks” with picturesque lights on the 36-kilometer shoreline

Since last year, the three-year action to improve the lighting of the central urban area has surged in Quanzhou, focusing on promoting the lighting improvement of “portal corridors, mountain line water systems, ancient city streets and alleys, and the New District around the Bay”, expanding the cultural context of Quanzhou Maritime Silk Road and the cultural heritage of the world. Influence and attractiveness. As a key project of this action plan, the lighting improvement project for the east area of Donghai City and the banks of Jinjiang and Luoyang Rivers came into being.

Starting from Jinji Barrage New Gate in the west, expanding eastward along the river, and reaching Luoyang Qiaotou Gate in the north, the 36-kilometer coastline on both sides of the two rivers is planned and designed in a unified manner. The organic combination of “core detonation”, 7 bridges such as Tian’an Bridge and Zaitong Bridge, 7 parks such as Beibinjiang and Jiangnan, facades along Donghai Street and 13 pedestrian overpasses, and nearly a thousand buildings are connected by points and lines. The promotion of noodles is connected in series to form a centralized display of “Two Rivers and One Bay”.

Aiming at the current situation of the region, the project is still making great efforts to enrich the urban texture level. The distant view emphasizes the spatial pattern of “mountain, city, and sea”. Viewing is from the perspective of citizens’ nighttime strolls, leisure and entertainment, enriching the interest and interaction of parks and squares along the line at night.

Interpretation of the three major elements of “Quanzhou Story” through ancient and modern times

On the Sunjiang Bridge, a long arched scroll unfolds slowly, and a picture scroll of China’s maritime trade in the Song and Yuan Dynasties leaps onto the “bridge”. Quanzhou cultural attractions such as Jiuri Mountain, Cliff Stone Carvings, and Laojun Rock in Qingyuan Mountain are presented one by one, creating a dazzling visual feast. The surrounding residents stopped to take pictures.

The Quanzhou element of Sunjiang Bridge is just a microcosm of the lighting improvement project on both sides of the river. In order to enrich the connotation of night scene lighting, the project incorporates three major Quanzhou elements such as “World Heritage Culture”, “Intangible Heritage Art” and “Quanzhou Spirit”. The theme gives a panoramic view of Quanzhou, a city full of pyrotechnics, poetry, and vitality, and tells the story of Quanzhou with light and shadow.

In line with the principle of “lighting up the whole and focusing on building”, in addition to Sunjiang Bridge, key areas such as Quanzhou Bridge, Shunji New Bridge, Zaitong Bridge, Tian’an Bridge, Taihe Plaza, and Donghai Central Business District have also passed “sound and light “, interpreting the development of Quanzhou from ancient times to the present, through the linkage with the lighting of surrounding buildings, forming a very diverse and charming night scene business card, adding a beautiful landscape to Quanzhou, the capital of cultural tourism.

4219 smart street lamps light up Yunyang County, Chongqing

In recent years, the country has vigorously promoted the construction of smart cities, and Yunyang County in Chongqing City is no exception. It has coordinated and built the “Urban One Light Project”. Now the main roads in Yunyang City have achieved full coverage of smart street lights.

4219 smart street lamps light up Yunyang County, Chongqing

As of December 2022, Yunyang County has newly installed 4,219 multifunctional smart street lights, covering a total length of 68 kilometers of smart lighting roads. You can see how “black technology” smart street lights can light up Yunyang.

1. Intensive renovation to help the city look good

In the past, there were many street light poles, video surveillance poles, traffic signal poles, road sign poles, etc. on the streets of Yunyang City. Traveling brings a lot of inconvenience, and it cannot meet the new infrastructure needs of 5G micro base stations and other equipment. In this regard, the Yunyang County Urban Management Bureau proposed the construction idea of “one pole with multiple functions”. It adopts a multi-functional smart light pole, installs it equidistantly, and lays an optical fiber pipe network to integrate 5G micro base stations, cameras, LED displays, etc. The sensing device is mounted on a light pole.

Smart street lights in Yunyang County use a combination of high and low arms to illuminate the roadway and sidewalk separately. The exterior design concept of the street lamp is based on the theme of “cloudy seasons, sunny mountains and rivers”, which is a fusion of “clouds” in the mountains and “water” in the Yangtze River. The shape is simple and elegant, and the atmosphere is elegant. The neatly arranged smart light poles have not only become the “heroes” for beautifying the city, but also have been given a higher value mission to improve the level of urban intensification and efficient management. “, is an important carrier of Yunyang smart city construction.

2. Light sensing, promoting the construction of smart cities

Traditional street lamps only have a single lighting function, which turns on and off at a fixed time. Sometimes it gets dark early and dawns late, and ordinary street lamps can’t sense it. This often causes unnecessary energy waste and the lighting effect on the road is also poor Not good, and may even increase security risks.

The smart multi-functional street lamp in Yunyang County not only integrates multiple functions, the biggest highlight is that it can realize remote monitoring and control, automatic intelligent monitoring of faults, according to the slope of the turning road, weather conditions, visibility level, seasonal sunshine changes, the brightness of the lighting It will change accordingly to give the road the most suitable brightness illumination and effectively save energy. For example, after 22 o’clock every day, when the traffic flow on the roadway decreases, the system will automatically reduce the power of LED lights, which not only meets the needs of road lighting, but also avoids energy waste. Smart light poles have good penetration in urban densely populated areas, and the layout is uniform and the density is appropriate. It can provide site resources and terminal carriers with wide distribution, excellent location, and low cost. It is the first choice for large-scale and in-depth deployment of 5G base stations in cities. .

The difference between smart street lights and traditional street lights is that it integrates urban management functions such as 5G micro base stations, environmental monitoring, video surveillance, LED display, one-key alarm, and emergency broadcasting. Smart street lights also have extended functions. In order to facilitate urban management, they can monitor the body temperature of traveling citizens, and even environmental impact assessment, environmental monitoring, and air quality data monitoring can be realized.

3. Implement “Double Carbon” and promote green ecological development

With the official implementation of the first national standard of China’s smart light pole industry last year, smart light poles ushered in a broader space for development. The new generation of information infrastructure represented by smart light poles has become an important carrier for improving the city’s energy level and core competitiveness, as well as a key enabler for promoting the development of the digital economy.

Under the background of “dual carbon”, green and low carbon have spawned new industrial opportunities, and continue to lead the development of the lighting industry in new directions. Deeply tap the potential of energy saving and consumption reduction. In May last year, combined with the promotion of LED light sources, the County Urban Management Bureau carried out intelligent upgrading and transformation of the light poles on the 2.2-kilometer section from Gangmao Hotel to Liangjiang Holiday Hotel on Migrant Avenue. A total of 127 light poles were upgraded and transformed. pole. After the transformation, the average monthly electricity consumption of this section has been saved by more than 800 kWh. In addition, more than 4,000 smart street lights in Yunyang City reduce carbon emissions by about 800 tons per year.

Using special LED lights, it only takes half the time to grow wheat

According to Dr. Brande Wulff, the leader of the research team, under normal circumstances, it takes four to five months for a crop to go from seed to harvest. By comparison, the team took just eight weeks to grow crops using specially adapted LED lights. At the John Innes Center for Plant Research in Norwich, UK, the research team irradiated the plants 22 hours a day and provided them with a rich nutrient solution. But even then, they wanted to experiment with growing techniques that were more energy-efficient than standard labs.

Using special LED lights, it only takes half the time to grow wheat

Dr Wulff said: “We urgently need to develop crops that can better adapt to future climates. It is a race against time to develop better crops. These new crops will be affordable, more nutritious, and higher yielding varieties, in order to help feed the world’s growing population.”

The crops are also known to be larger and healthier than those grown under normal growing conditions. The researchers mainly used LED lights that can emit blue and red light needed for photosynthesis in plants. Most laboratories and greenhouses use sodium vapor lamps similar to street lamps.

Dr. Wulff pointed out that most of the yellow light and green light emitted by sodium vapor lamps are not needed for plant growth, while LED lights can just provide the light needed for plant photosynthesis.

However, because it is impractical to irradiate large farms at night, the team’s “rapid breeding” technique cannot be applied to farms. But Dr Wulff said the findings could speed up the progress of crop research, leading to better-adapted crops that are more nutrient-dense and require fewer chemicals.

In addition, the research team is also trying to grow six generations of barley, peas and chickpeas in one year.
