Intelligent street lights in Suzhou-Chuzhou High-tech Zone, Chuzhou, Anhui

With the continuous improvement of the level of smart urban management, it is quietly affecting our lifestyle and urban appearance. In order to comprehensively improve the refinement and intelligence of the management of public lighting facilities in the Zhongxin Suzhou-Chuzhou High-tech Zone in Chuzhou City, Anhui Province, Suzhou-Chu Municipal Utilities actively explored new energy-saving paths and carried out the construction of smart street lights in the park.

Intelligent street lights in Suzhou-Chuzhou High-tech Zone, Chuzhou, Anhui

Since September this year, Suzhou-Chuzhou Municipal Utilities Company has upgraded and renovated the public lighting facilities on the main and secondary roads of the park for energy saving and intelligent management and control, with a total investment of about 11 million yuan. Mainly installed about 7,000 sets of single lamp controllers and 102 sets of centralized managers, replaced about 2,400 dimming drive power supplies, and replaced more than 3,500 old high-pressure sodium lamps in the park with new LED lamps with high light efficiency and low color temperature.

At the same time, a digital management system for smart street lights has been built. Through the system, you can directly view the type, quantity, location, operating status, lighting rate and other information of street lights, and the park street lights can achieve “one picture, visualization” management and control. The system has a remote control function. Managers can check the operation of street lights anytime and anywhere through mobile phones or computers, and adjust the disposal according to the actual situation, which greatly improves work efficiency and management level. The system can not only monitor the working status of each street light in real time, but also automatically adjust the brightness according to the changes in ambient light, ensuring that it meets the nighttime lighting needs while avoiding excessive consumption of electricity.

Lanzhou University researchers develop highly efficient phosphor for high-power laser-driven lighting

Lanzhou University Wang Deyin@Wang Yuhua LPR replaced the Al3+-Al3+ pairs in BaLu2Al4SiO12: Ce3+ with Mg2+-Si4+ pairs to prepare a new blue-light-excitable yellow-emitting phosphor BaLu2(Mg0.6Al2.8Si1.6)O12: Ce3+, with an external quantum efficiency (EQE) of 66.2%. While Ce3+ emission red-shifted, this substitution also broadened Ce3+ emission and reduced its thermal stability. The change in the spectrum is due to the change in the local crystal field of Ce3+ and the change in positional symmetry caused by the Mg2+-Si4+ substitution.

Lanzhou University researchers develop highly efficient phosphor for high-power laser-driven lighting

In order to evaluate the feasibility of the newly developed yellow-emitting phosphor for high-power laser lighting, it was constructed as a phosphor wheel. Under the irradiation of a blue laser with a power density of 90.7 W mm2, the luminous flux of the yellow phosphor was 3894 lm, and there was no obvious emission saturation phenomenon. The yellow phosphor wheel was excited by blue laser diodes (LDs) with a power density of 25.2 W mm?2, generating bright white light with a luminance of 1718.1 lm, a correlated color temperature of 5983 K, a color rendering index of 65.0, and color coordinates of (0.3203, 0.3631).

These results indicate that the newly synthesized yellow-emitting phosphor has significant potential for high-power laser-driven lighting applications.

The night scene lighting along the Yan’an Road Elevated Road in Shanghai has been upgraded again

As a backbone traffic artery that runs east-west across the central urban area of Shanghai, the Yan’an Road Elevated Road is an extremely important part of Shanghai’s urban night scene. Since 2022, after three years of construction, the night scene along the Yan’an Road Elevated Road has a certain scale and influence. The third phase of the Yan’an Road Elevated Road project creates a warm, elegant, prosperous and fashionable night city light environment through new construction, renovation, upgrading and retention, further enhancing the night scene image of the main axis of Jing’an District “Excellent Huaguang, Brilliant Jing’an”.

Large-scale group design, star-studded night scene lighting

After multiple on-site surveys and analyses, the area around the Huashan Road ramp, the Yan’an Road Elevated Road and the ground municipal roads are all areas with relatively serious traffic congestion. At the same time, the Huashan Road overpass has a relatively wide field of vision, and the line of sight basically overlaps with the elevated driving line of sight. Therefore, the buildings around the skybridge are used as carriers, and the large-scale group design is carried out. The highlights are highlighted by combining the characteristic elements of the buildings in some parts, and the overall coordination of the surrounding lighting is rationally planned to create a representative model of Shanghai’s urban night scene.

Iconic and exquisite design, outstanding and dazzling night scene lighting

Jiadi Center and Wenxin News Building are two buildings with upright shapes and distinct architectural features, occupying important positions in their respective areas. Lighting focuses on fine depiction according to its own functional attributes and architectural element characteristics to create an iconic night scene in a small area. Jiadi Center is located at No. 968, Beijing West Road, a prime location in Jing’an District. It is a unique high-rise fashion landmark. Its architectural design style is modern and full of elegant temperament, standing out among the high-rise buildings. Whether driving on the Yan’an Road Elevated Road or the North-South Elevated Road, or along the Suzhou River, you can see it. The night scene lighting focuses on the shape of the “crown” on the top of the building, making it more dazzling.

The Wenxin News Building is 170 meters high and is close to the Yan’an Road Elevated Road. When driving on the Yan’an elevated road, whether traveling from east to west or from west to east, the Wenxin Newspaper Building occupies the center of vision for a long time. The lighting uses linear lighting techniques to highlight the main body of the building, emphasizing its uprightness and creating a small-scale iconic night view building.

The second phase of the green energy-saving and intelligent innovation and transformation project in Baotou, Inner Mongolia has been officially completed

Good news! The second phase of the 2024 Baotou City Street Light Green Energy-saving and Intelligent Innovation and Transformation Project, which was implemented by the Municipal Affairs Development Center of the Baotou City Administration Bureau of the Inner Mongolia Autonomous Region, was fully completed a few days ago. The street lights under the jurisdiction of the Municipal Affairs Development Center have officially entered the “sodium-free era”.

The second phase of the green energy-saving and intelligent innovation and transformation project in Baotou, Inner Mongolia has been officially completed

The main implementation content of the second phase of the project is to transform a total of 5,280 sets of original sodium lamps on 29 roads throughout the city, including Qingshan Road, Tuanjie Street, Bayantala Street, Jian’an Street, and Century North Road, into LED modules. The project arranged a total of 30 professional and technical personnel and mobilized 5 aerial vehicles to work simultaneously. Under the premise of ensuring construction safety and quality, the construction personnel reversed the construction schedule, accelerated the transformation speed, and ensured the project was completed ahead of schedule.

After the completion of this project, all 11,125 high-pressure sodium lamps under the jurisdiction of the Municipal Development Center have been renovated, and the outstanding problems of the original sodium lamps (high power consumption, high operation and maintenance costs, high failure rate, low road illumination, low color rendering index, and low light uniformity) have been effectively improved. Compared with 2021, after the completion of this renovation of all street lamps, it is estimated that 2.43 million yuan in electricity bills will be saved each year, and carbon emissions will be reduced by about 5,026 tons each year, helping Baotou City achieve its “dual carbon” goals.

Sports facilities in Chengbei Park in Nanchong, Sichuan Province are fully lit

At about 7 p.m. on September 10, the reporter saw that citizens came to Chengbei Park in Nanchong City, Sichuan Province to play basketball, run or exercise with fitness equipment.

At 7:30 p.m., the four high-pole lights in the park were lit on time. When the lights are on, the basketball court, football field, track and field, and badminton courts have a very ideal lighting effect in the night. Citizens no longer need to “find in the dark” when they go out at night, and security guards no longer need to use flashlights when patrolling.

When the reporter interviewed earlier, only a few people in the basketball court were practicing shooting under the lighting of mobile phones. This time, two teams are playing freely on the court.

“Chengbei Park started to light up the lights on the evening of September 9.” A citizen who played basketball told reporters that in order to avoid the high temperature, everyone could only come to play basketball in the evening and leave after dark. After learning that the park was lit up, they made an appointment to play basketball in the park at night.

The reporter noticed that, except for the basketball court, football field, track and field, and badminton court, other areas of the park, including the children’s playground, are not lit yet, making it inconvenient for night tours.

At around 9 p.m., the security guards reminded the citizens to leave the park in time through the loudspeaker. At 9 p.m., all four high pole lights were turned off.

Zeng Huilin, deputy director of the Shunqing District Park Affairs Center, introduced that some areas of Chengbei Park have been opened. For areas that have not yet been opened, the center is urging the construction party to install the relevant supporting facilities as soon as possible so that the park can be fully opened as soon as possible. By then, the park’s night lighting facilities will be turned on for a long time to fully guarantee citizens’ nighttime park tours.

“At present, the basketball court, football field, and badminton court are all open to the public free of charge.” Zeng Huilin reminded citizens that before the park’s night lighting facilities are fully turned on, please do not go to the insufficiently lit areas to avoid safety accidents. During the visit, please cooperate with the management of the Park Affairs Center and leave the park in time before the lights are turned off.

More than 4,000 street lamps in Jianyang District, Nanping, Fujian Province are equipped with the “strongest brain”

In the early morning, the floodlights on the 275 new Chinese lanterns on Jianping Avenue in Jianyang District, Nanping City, Fujian Province suddenly turned off, the bright moon was shining in the sky, and the surrounding environment fell into a quiet.

More than 4,000 street lamps in Jianyang District, Nanping, Fujian Province are equipped with the "strongest brain"

Wu Xun, a staff member of the Municipal Service Center: “We use the ‘smart street lamp’ system to adjust the lighting time of the floodlights on the Chinese lanterns on Jianping Avenue to 18:20 to 00:00, that is, to turn them off with one click in the second half of the night when there is less traffic, which not only ensures night lighting but also saves energy.”

The Jianyang District Urban Management and Comprehensive Law Enforcement Bureau firmly establishes the concept of high-quality urban development centered on the people, scientifically and rationally plans and layouts, improves functions to highlight care, accelerates the energy-saving transformation of urban “smart street lamps”, and strives to create a harmonious and beautiful urban night scene, creating a new engine and injecting new momentum to drive the growth of the “night economy”, and constantly meeting the people’s growing needs for a better life.

Small street lights in Xinxiang, Henan Province illuminate the people’s livelihood

As night falls, Hongzhou Township, Huixian County, Xinxiang City, Henan Province is brightly lit. Under the street lights, there are bursts of laughter and children’s play. People gather in groups of three or five in the square, singing and dancing, creating a new scene of joy and peace in the countryside. This change is due to the effect of centralized rectification.

Since the launch of the special action of centralized rectification, Hongzhou Township has vigorously carried out activities to collect urgent and difficult problems of the masses, divided the whole township into 35 grids, and the cadres of the organs visited the grids to establish a full-staff responsibility system. Through the visit, it was learned that “since the opening of Hongzhou Township Community Street, namely the Hongzhou section of S311, due to many factors, street lights have not been installed on this section, resulting in difficulties for local villagers and students of the central school to travel at night, and safety cannot be effectively guaranteed.” After that, the Party Committee organized a research and judgment meeting and included the problem in the list of urgent and difficult problems of the masses. Immediately After a lot of communication and coordination, more than 100,000 yuan of funds for the purchase of street lights were raised. The working group members went from village to village, solicited opinions from residents, schools, shops and enterprises along the road, surveyed the locations of the entire road section, determined the quantity, and estimated the cost, formulated an installation plan, studied the feasibility of street light installation, and increased the number of street lights near the central school. During the installation, the staff worked day and night, closely monitored the manufacturer’s delivery progress, stood guard in the middle of the night waiting for delivery, inspected the quality of the street lights, and manually moved and placed them one by one. 56 solar street lights were successfully completed and put into use in just three days, covering more than 1,600 meters of roads, which not only solved the safety hazards of people’s night travel, facilitated vehicles to drive at night, but also improved the overall image of Hongzhou Township.

Combined with the “four deep and four clear” work, through further comprehensive investigation, it was found that Xitulou Village and Sili Miao Village had problems such as aging and damage of street lights, which affected the production and life of the people. To this end, the Party Committee and Government of Hongzhou Township urged the two villages to implement the street light renewal project. Xitulou invested more than 90,000 yuan to install 58 new solar street lights; Sili Miao invested more than 30,000 yuan to replace 110 solar street lights. With the active cooperation of the two villages, the street lighting project was rapidly promoted. It took only one month from fundraising to installation. We coordinated with relevant departments and communities to discuss solutions, set up a working group, and assigned special personnel to follow up the whole process to fully promote the “road lighting” action.

Photovoltaic street lights in Taihu County, Anqing, Anhui Province illuminate the road to happiness

In the beautiful Jieling Village, Mituo Town, Taihu County, Anqing City, Anhui Province, as night falls, newly installed photovoltaic solar street lights quietly shine, lighting the way home for the villagers, and lighting up the road of rural revitalization in Jieling Village.

Insufficient lighting at night has always been a major problem that has plagued the lives of villagers. In order to completely solve this problem, Jieling Village, after in-depth market research and comparison, finally decided to introduce energy-saving and environmentally friendly photovoltaic solar street lights as a solution. This type of street light does not require an external power supply and relies entirely on solar power generation, which not only reduces energy consumption, but also reduces environmental pollution, in line with the concept of green development.

By seeking support from superiors and mobilizing villagers to participate in the construction, with the joint efforts of everyone, from the purchase, installation to debugging of street lights, every link embodies the sweat and wisdom of the villagers. Digging pits, erecting poles, wiring… Every process witnesses the villagers’ yearning and pursuit for a better life. After a period of intensive construction, all the photovoltaic solar street lights were finally installed, achieving a 100% lighting rate for the village roads, adding a touch of warmth and brightness to the nights of Jieling Village.

380 LED street lights installed in Guangyuan City, Sichuan

On the evening of August 14, walking in Yangliu Village, Hexi Street, Lizhou District, Guangyuan City, Sichuan Province, the mountains and rivers are beautiful, the trees are shady, and the solar street lights are automatically lit up and winding. The villagers are walking and walking in groups of three or five, enjoying themselves.

“It was dark when I went out at night before, and there were many large trucks on this road. I was still a little scared to go out at night, so we asked the village if we could install some lights.” When mentioning the street lights in Xin’an, villager Yang Heping couldn’t help but praise. “Now I feel more at ease. Everyone often makes an appointment to walk to the square after dinner to digest food.”

It is understood that due to the limitations of development conditions, Yangliu Village, Hexi Street, has a steep terrain and is located in a valley area. The village roads are relatively narrow and unlit, making it inconvenient for villagers to travel at night. Because the village is connected to Yangmu Town, Chaotian District in the west, there are many large trucks passing through, and there are safety hazards in traveling at night, and the masses have great opinions.

In the face of the masses’ demands, “solution” is more important than “explanation”. In order to accurately and effectively grasp the situation reflected by the masses, Hexi Street relies on the “Come to Consult if You Have Anything to Do” platform, closely focuses on the difficulties in the lives of villagers, and orderly conducts small-scale consultations to help solve the urgent problems of the masses. After verification, Yangliu Village and Baishan Village under the jurisdiction of Hexi Street have not had street lighting, which has greatly affected the villagers’ night travel activities. Installing street lights has always been a strong desire of local villagers.

In order to effectively solve the problem, the street actively sought 376,000 yuan of provincial financial connection subsidies from relevant departments this year to support the construction of village road street lights. Since June, the “village street light project” has been officially included in the annual “doing practical things for the people” list. After many visits and consultations, cadres and the masses have opened up channels for discussion and brainstormed, and formulated a final solution for the installation points, maintenance and management of street lights.

After more than two months of construction, 380 solar street lights in the two villages have been basically put into use, benefiting 541 households and 1,666 villagers who travel at night, greatly improving the safety index of people’s night travel. Nowadays, whenever night falls, rows of street lights are lit up, like stars illuminating the night of the countryside.

“The interests of the masses are no small matter. The improvement and upgrading of infrastructure have enhanced the villagers’ sense of gain, happiness and security.” Chen Fengjie, secretary of the Party Working Committee of Hexi Street, said that the street will continue to promote the key tasks of rural revitalization throughout the year, continuously promote the upgrading of rural infrastructure and the high-quality and balanced supply of public services, rely on the new era civilization practice station, deepen the improvement of rural living environment, and steadily promote the transformation of customs, and strive to paint a beautiful picture of a livable, business-friendly and beautiful countryside.

New street lights installed on fitness paths

“I didn’t expect the problem I reported would be solved so quickly. Now we can come here for a walk very conveniently at night.” Aunt Fan, a neighbor living in Zhongshe Community, said happily. Longdong Cultural Square has always been a place for residents in the area to relax and have fun. Many neighbors play ball, dance, run and walk here every day.

New street lights installed on fitness paths

Recently, some neighbors reported that the fitness path near the Erheng Road of Longdong East Road in Longdong Cultural Square, Tianhe District, Guangzhou City, had no street lights, so residents had to take a detour every night. They hoped that the relevant departments would coordinate to solve the problem of installing street lights to facilitate everyone’s travel and activities.

After receiving the opinions of the residents, the staff of Zhongshe Community, Longdong Street, immediately went to the scene to understand the situation. After verifying the situation, the General Party Branch of Zhongshe Community immediately used the relevant funds to implement the lighting project of the fitness path of Longdong Cultural Square. More than ten days later, the lighting project of the fitness path of Longdong Cultural Square was successfully completed, and more and more neighbors came here to run, walk and sit at night.

It is reported that since the beginning of this year, Longdong Street has invested more than 4 million yuan on the basis of solid research and selection of topics, and launched 58 key livelihood projects. It has coordinated with multiple parties to solve a number of people’s worries and concerns, such as the lack of electric bicycle charging piles, no street lights on the fitness path of the cultural square, few stone benches and stone tables in pocket parks, no rest and charging places for takeaway riders, damaged roads within the community, and difficulty in installing elevators in old buildings.

According to the relevant person in charge of Longdong Street, Longdong Street insists on serving the people first and carrying out the “Your Wish, My Volunteer” – the “Double Micro” action of party organizations and party members doing practical things for the masses. Up to now, local party organizations, street party members, community reporting party members, etc. have taken the lead in claiming 125 “micro wishes” of the masses, and have taken the lead in hosting and completing 67 “micro projects” such as “Love the River, Protect the River, and Clear the River”, “Patrol the Mountains and Rivers”, “Garbage Classification Station Buckets”, and “Build a Beautiful Balcony to Help Green and Beautiful Ecological Construction”, so that the masses have a stronger sense of gain, a more sustainable sense of happiness, and a more secure sense of security.
