A new picture of green transformation: green transformation with a lamp
In the 75 years since the founding of New China, especially since the 18th National Congress of the Communist Party of China, all parts of the country have worked hard to implement the concepts of ecological priority and green development, and the construction of Beautiful China has made important progress and remarkable results.
This newspaper will launch a series of reports on the "New Picture of Green Transformation" from now on, focusing on small incisions such as a lamp, a car, and a farm, showing the vivid practices of various parts of China in promoting the green transformation of economic and social development, and telling the world The vivid story of beautiful China.

In the early morning, he watched the national flag rise and the lanterns turn off; as night fell, he looked around and watched the lanterns first come on. Chen Chunguang couldn't count how many days and nights there were.
Chang 'an Street in the capital Beijing is of great significance to the hearts of every China and is also a window for the world to understand China. Whenever night comes, Chang 'an Street will be lit up by lanterns.
In Tiananmen Square, in addition to the well-known "National Flag Class", there is also an unknown group-the "Hua Deng Class". No matter spring, summer, autumn and winter, cloudy, rain, snow, etc., they stick to the front line and guard the light of the lanterns. Not long ago, the reporter walked into the Hua Deng Class of the Beijing City Urban Lighting Management Center and came to Chen Chunguang, the fifth squad leader, to listen to him and his colleagues telling the story of "China's No. 1 Light."
From incandescent lamps to electrodeless lamps--
The lanterns are brighter and more energy-efficient
There is a song that sings: "You can see the Milky Way in the sky and the lanterns in Beijing; no matter how vast the night is, you can still see bright Beijing..."
Meng Qingshui, the fourth squad leader of the Huadeng Class, has been with Huadeng on the front line for 38 years. Although he has retired, he still talks about Huadeng as if he is familiar: "In 1959, on the eve of the 10th anniversary of the founding of New China, the Huadeng was personally named by Premier Zhou Enlai and built simultaneously with the top ten buildings in the capital. Now, there are 253 basic lanterns and more than 6000 light sources on Chang 'an Street from Xidan to Dongdan."
Meng Qingshui introduced that the lotus lamp in Tiananmen Square consists of 9 balls, and the cotton peach lamps on the east and west Chang 'an streets consist of 13 balls. The round lamp ball and the square base symbolize a round sky and a peaceful world.
Over the past 65 years, the shape of the lanterns has remained the same, but the light sources have been constantly updated.
When the lanterns were first put into use, the light source used was incandescent lamps. "At that time, summer was most feared. The light bulbs would easily break when it rained and had to be replaced one after another." The old masters in the Hua Deng Class recalled that incandescent lamps are hot light sources with high wattage and become extremely hot for a while."It's so hot that we can roast white potatoes. When we change the light bulbs, we feel hot even wearing protective gloves."
On the eve of the 35th anniversary of the founding of New China, the light source of Hua Deng underwent its first upgrade. Self-ballasted high-pressure mercury lamps replaced incandescent lamps, and new floodlights were also installed under the ball lamps. "From the 1960s to the 1990s, lanterns were only turned on during major festivals and were mainly used as landscape lighting." Wang Qingyu, the first squad leader of the Hua Deng Class, once said in an interview that every major festival, the performance activities held in Tiananmen Square at night have high requirements on lighting."We have to make multiple light adjustments in advance every time. In order to ensure that everything is safe, we have our people watching under the base Hua Deng."
From 2006 to 2008, the then Beijing City Street Light Management Center upgraded the light source of Huashan twice, replacing the 450-watt self-ballasted high-pressure mercury lamp in the Huashan with an 85-watt electromagnetic electrodeless induction lamp, and replacing the 500-watt emergency incandescent lamp with self-reflection in the Bajiao Pavilion. It was replaced with a 100-watt electromagnetic electrodeless induction lamp. "Light sources with high light efficiency and low energy consumption greatly reduce the probability of lamp failure. Most light sources can run for more than tens of thousands of hours." Meng Qingshui said.
From 500-watt and 1000-watt incandescent lamps, to 450-watt self-ballasted high-pressure mercury lamps, to 85-watt electromagnetic electrodeless induction lamps, Hua lamps increase brightness while also saving energy.
"As Beijing's iconic landscape and lighting facilities, the green transformation of Hua Deng over the past 65 years is a microcosm of China's development. Our lives are becoming more and more green and low-carbon." Chen Chunguang said.
From wooden shelves to high technology--
Huadeng cars have more functions and are more environmentally friendly
The lanterns add a lot of charm to Chang 'an Street. In order to ensure that the lanterns are always displayed in front of the world in the most beautiful manner, the lantern squad is not idle every day for cleaning, maintenance, and inspection.
The elevator slowly rose, and Chen Chunguang led his colleagues in the Hua Deng class to start the Hua Deng inspection operation against the sun. "In addition to daily inspections, from June to September every year, from 10 a.m. to 4 p.m., it is our regular time to clean and repair the lanterns." Chen Chunguang said.
The lanterns are more than 10 meters high. Cleaning and maintenance is not an easy task.
In 1960, the lanterns were cleaned for the first time. According to the memories of the old masters in the lantern squad, the tools used to clean the lanterns at that time were unexpected to many people-the branches and leaves of the fir tree trunk were cut off, made into slender poles, and then fixed and tightened with lead wire to form a fir pole frame. Lay a board on the wooden frame, and in this way, the old masters began to work leisurely.
To clean a lantern, you have to move the shelf three or four times. There is also a large bamboo basket beside you. You need to tie a rope to transport the lampshade to the ground. People on the ground will wash and dry it and then pass it up in the bamboo basket. Only one lantern can be cleaned in the morning.
"Until 1972, Beijing City established an early street lamp team, which was the predecessor of the Beijing City Urban Lighting Management Center, which was responsible for repairing and cleaning lanterns. Four years later, the first generation of Hua Deng cars came out." Chen Chunguang said.
Over the past 40 years, Huadeng cars have been continuously upgraded and iterated, with more and more functions and becoming greener. The fourth-generation Huadeng truck is equipped with a sewage treatment and circulation system. Used wastewater will be recycled into the waste water tank. After precipitation and filtration, it can be reused.
In 2019, the fifth-generation Huadeng was officially put into use. It is also the Huadeng currently in use. It integrates multiple functions such as vehicle positioning, route planning, and condition monitoring.
The fifth-generation Hua Deng has a smarter "brain"-on the intelligent operating platform, the visualization system can provide a panoramic view of the lifting process and equipment parameters, sense the working process and equipment status in real time, and transmit data back through the network in real time. Back to the background, the personnel on duty can interact with the scene in real time.
Energy conservation and environmental protection are the outstanding features of the fifth-generation Huadeng vehicles. In the corner of the car's operating platform, there is a transparent "glass cabinet" on all sides. "This is a newly added automatic Hua Deng cleaning machine. It is different from the previous manual way of washing light balls. When the fifth-generation Hua Deng truck is operating, we only need to put the removed Hua Deng ball into the card slot to realize automatic cleaning. The speed is twice as fast as manual work, saving cleaning time." The staff of the Hua Deng Class said.
Not only that, the dust blowing system of the fifth-generation Huadeng has also been greatly improved. "The original fixed dust blowing system has been changed into a handheld suction and blowing integrated structure, so that we can move operations on site. In addition, the dust blowing system has added a hose shampoo and cleaning appliance with stronger decontamination ability. While avoiding pollution to the environment caused by dust blowing, it also avoids dust damage to operators." Chen Chunguang said.
Speaking of the fifth-generation Hua Deng car, Chen Chunguang and his colleagues have a lot to say. The Huadeng Class was directly involved in the research and development and design of this car. The concepts of green, low-carbon, energy conservation and environmental protection were integrated into this car from the beginning.
"The annual cleaning and maintenance of lanterns is the hottest time of the year, so we wonder how to utilize the heat. With the collective efforts of everyone, the fifth-generation Huadeng vehicle uses thin film photovoltaic solar collection panels, which can not only provide power for common power tools, but also provide test power for Huadeng maintenance, saving resources and reducing carbon emissions." Chen Chunguang said.
According to reports, the chassis, working platform devices, as well as all parts and components of the fifth-generation Huadeng vehicle have all been localized. "Huadeng cars are gradually transforming into 'intelligent manufacturing' and upgrading to 'high-end'." Chen Chunguang said.
From naked eyes to "clairvoyance"--
Hua Deng monitoring is more accurate and smarter
A lighting rate of 98% is the requirement of the higher-level department for the Hua Deng Class. In the hearts of all members of the Hua Deng Class, 100% is their goal.
How to ensure that the lights stay on forever? With the help of continuously developing new technologies, the Huadeng Class has increased the "treatment of diseases before they are" frequent inspections "and used advanced technical means to prevent problems before they occur.
In 2012, the Beijing City Urban Lighting Monitoring Command Center was completed to implement integrated management and monitoring of more than 300,000 street lights in the city. On the big screen, the lanterns on Chang 'an Street can be seen at a glance.
A year later, a single lamp monitoring device was installed on the 253-base lamp. "This monitoring device can be said to have provided us with a 'clairvoy', which can understand the lighting conditions of every light source on every basic Chinese lantern. Problems that we used to have to go to the scene to find with the naked eye can now be grasped more accurately." Chen Chunguang told reporters that for the Hua Deng squad, no matter which light bulb fails, a prompt can be issued to facilitate immediate response and maintenance.
With the continuous improvement of the network, in 2023, the Hua Deng single lamp monitoring system has been upgraded. After replacing it with a 4G communication module, the volume and speed of data transmission have been improved. A safety battery has also been installed, which can be realized. Go online 20 minutes before the Hua Deng is started.
"During the cleaning and maintenance of lanterns this year, new lanterns signboards were put on duty." Chen Chunguang introduced that the new signboard also adds a QR code to the original signboard displaying ownership and repair telephone information to realize interactive functions. Citizens or tourists can scan the code to learn more about the lanterns, or they can scan the code to repair faults with one click.
At the same time, the new signboard has built-in monitoring elements to realize lamp pole leakage monitoring and verticality monitoring functions. Once the light pole leaks or tilts, the new signboard can send back information to the background of the system in a timely manner, providing support for the safe operation of the lantern.
Today's lanterns have realized intelligent turning on and off, and their status can also be monitored accurately in real time. At night on Chang 'an Street, lanterns illuminate everyone's way forward.
Over the past 65 years, behind the green transformation of Huadeng is inseparable from the continuous inheritance of generations of Huadeng people.
Song Xiaolong, secretary of the Party branch of the Huadeng Class, recalled that when he first boarded the Huadeng Car in 2003, he did not have the fear and dizziness often encountered by novices. Instead, he was excited: "I have always wanted to understand why the older generation of Huadeng people will work here all my life."
From that moment on, Song Xiaolong also became a member of the "capital lanterns". His doubts had long been answered, and the excitement at the beginning had long been transformed into heavy responsibilities and missions.
Not just lanterns, behind every green transformation on the land of China, there are vivid footnotes left by the struggling China people.
