How smart street lights accelerate the transformation of smart cities?
Written By Calio Huang
Smart street lights are an important part of a smart city. It uses urban sensors, power line
carrier/Zigbee communication technology and wireless GPRS/CDMA communication technology
to connect street lights in the city to form an Internet of Things, enabling remote centralized
control and management of street lights, based on traffic flow, time and weather. Condition
setting scheme such as situation.
The city has a large number of street lights and is the densest urban infrastructure for
information collection and distribution. The future of smart streetlights is an important source of
information collection for the Internet of Things. Urban smart streetlights are an important part
and important entrance for smart cities, which can promote the development of smart
municipalities and smart cities in urban lighting business, and enhance urban and municipal
service capabilities.
Smart street lights are the best gateway and service port for smart cities
Smart street lights are an important part of a smart city. It uses urban sensors, power line
carrier/Zigbee communication technology and wireless gprs/cdma communication technology to
connect street lights in the city to form an Internet of Things, enabling remote centralized control
and management of street lights, based on traffic flow, time and weather. The condition setting
scheme such as the situation automatically adjusts the brightness, remote lighting control, fault
active alarm, lamp cable anti-theft, remote meter reading and other functions.
Smart street lights can effectively control energy consumption, save power resources, improve
public lighting management, reduce maintenance and management costs, and use information
processing technologies such as computing to process and analyze massive sensing information,

including people's livelihood, environment, and public safety. The various needs within the
company make intelligent response and intelligent decision support, making urban road lighting
reach a "smart" state.
What are the functions of smart street lights?
From the perspective of lighting, what functions should smart street lamps cover?
1. Remote measurement of electric parameters such as current and voltage of street lamps,
remote control switch street lights, and on-site operation of important sections of remote
viewing.
2. Monitor the temperature of the led street lamp chip pad or the temperature of the lamp
housing and fault diagnosis.
3, daylighting or human-induced induction of dimming, as well as time-control in energy-saving
control and even achieve rtc dimming.
4. According to the monitoring data of the lamps, timely grasp the location of the abnormal
street lamps and the abnormal reasons, and have the purpose to repair, without going to the city
to inspect, speed up the maintenance and reduce the maintenance cost.
5. The lighting standard level on the same road changes with time and traffic flow becomes a
variable value. For example, some new development roads may have lower brightness at the
beginning of the passage. After a period of time or through monitoring traffic flow, a certain
threshold is turned on.
6, in some people in the sparse area in the middle of the night, can be controlled half-bright, but
when the car passes, it reaches a certain distance in front of the full light, and the rear returns to
the original brightness after a few seconds.
Frequent policies and vigorous promotion of smart lighting
As an infrastructure, street lamps are characterized by orderly distribution, extensive coverage,
and the presence of electricity in cities. If it is only used for lighting, it is obviously not fully
utilized. Therefore, when the demand for multi-pole and 5g micro base stations is gradually clear,
the smart light pole has been strongly advocated and motivated by the policy.
The Ministry of Industry and Information Technology and the State-owned Assets Supervision
and Administration Commission issued the "Implementation Opinions on Promoting the
Co-construction and Sharing of Telecommunication Facilities in 2018", pointing out that it is
necessary to actively promote the two-way sharing of communication towers with streetlights,
monitoring, traffic instructions and other tower resources. The Shenzhen government also plans
to fully realize the full coverage of the main smart roads in Shenzhen by 2020, and build a
multi-functional smart rod management platform. It can be said that the signal released by the
government is clear and the goal is clear: to create a successful replicable smart light pole project
model and then expand to regional and urban areas.
Smart street light poles become "all-rounder", 5g micro base station function is eye-catching.
At present, as an indispensable infrastructure for urban development, the smart light pole has
the characteristics of power supply, networking, and wide distribution. It can be used not only as
of the data collection end, but also as a data terminal, integrating surveillance cameras, 5g micro
base stations, security alarms, and other hardware. Through information perception and big data
interaction technology, it can realize intelligent lighting, intelligent transportation, wireless city,

information release, and other functions.
Among them, the eye-catching is the 5g micro base station function. According to a report
released by the American Association of Wireless Communications and International Networks
(ctia), urban street lights will be an important infrastructure in the 5G era. According to the
report, the densely distributed 5g small base stations are the key foundation for smart cities.
Municipal and regulatory agencies should streamline the approval process, adjust the fee
structure, and encourage telecom operators to make full use of urban infrastructures such as
street lights and poles to build 5G networks.
Hao Yingtao, president of Huawei's wireless site, said that the 5g network will be deployed by a
wave. The first wave is mainly based on macro stations, and the second wave is mainly based on
the deployment of 5g pole base stations. It is expected that the scale will be formed after 2020.
By then, it will usher in a new round of growth: According to ctia, the market size of various
hardware and services based on smart light poles in China in 2021 maybe 3.7 trillion yuan,
accounting for 20% of the total size of the smart city market.
Multi-pole integration is costly and requires a mature business model
Although the government has specific targets for the promotion of 5g and pilot programs in many
cities, it is still difficult to apply in large quantities in the short term, which is due to funding and
budget. It is estimated that about 240,000 streetlight poles in Shenzhen will be “multi-bar
combined”, and the initial cost will be as high as RMB 50 billion.
Smart cities can't just be castles in the air or limited to small-scale test scenarios. The benefits of
smart networking and urban transformation can be expected and expected. However, the
transformation of smart light poles must first solve the problem of the era of infrastructure
construction. It also needs to be combined with 5g technology and mature commercial operation
environment to get rich returns.
Smart lighting should have 3i features. First, it senses the state of all objects and environments
with sensors. A more thorough perception of surveillance cameras, sensors, rfids, data centers,
data mining, and analysis tools, mobile and handheld devices, computers and multimedia
terminals in a lighting environment provides a rich variety of external data.
Smart street lights are the product of the division of the industry. Led module, wifi/micro base
station, monitoring, single lamp controller and other modules, all have mature manufacturers. It
is almost impossible for a company to complete the R&D and manufacturing of all modules. The
professional division of labor and modular design are the only way for mature industrial products.
Multi-function (smart) street lights are actually the carrier for information collection, processing,
and distribution. Multi-functional street lamps can bring about the need to save land occupation,
integrate resource utilization, and enhance the image of the city. At the same time, module
standardization, style diversification, and configuration specialization are the future development
directions of multi-function street lamps.
The construction of smart cities is progressing steadily, and the demand for smart street lamps
can be expected.
In recent years, building smart cities and promoting urban development have been included in
important work areas by the state. Deloitte's "Super Smart City Report" shows that there are
more than 1,000 smart cities that have been launched or under construction in the world, and

China is building 500, far exceeding the second-ranked Europe (90). Judging from the distribution
of smart cities under construction, China has initially formed four clusters of smart cities in the
Bohai Sea, the Yangtze River Delta, the Pearl River Delta and the central and western regions.
According to the "Super Smart City Report", there are currently 500 smart cities under
construction in China. According to the plan, from 2016 to 2020, China will cultivate 100 new
smart cities. Smart cities have a clear driving role in the development of medical, transportation,
logistics, finance, communications, education, energy, environmental protection, and other fields,
and will provide sustained support for the sustainable development of cities and the economy.
In the process of the formation of the four smart city groups, the IoT industry cluster including
chip manufacturing, sensor equipment, and system integration has also gradually grown and
developed based on the above-mentioned core cities.
As an important part of a smart city, smart street lights have also been highly valued and
promoted by relevant departments. At present, with the acceleration of urbanization, the
purchase volume and construction scale of urban public lighting facilities are increasing, forming
a huge purchasing pool. However, the consequent urban lighting management contradictions are
becoming more and more obvious. The three most prominent contradictions are the great
consumption of energy, the excessive maintenance cost of lighting fixtures, and the
incompatibility with other public equipment. The emergence of smart lighting will undoubtedly
greatly change this situation, and effectively promote the acceleration of the smart city process.
Streetlights are an indispensable public carrier for urban lighting and one of the “facades” of a
public image of a city or region. With the development of cities around the world, the number of
street lamps is expected to reach 350 million in 2025. According to the "Global Smart City 2017"
report released by IDC, by 2019, China's LED street lamp replacement will exceed 30 million, and
the expenditure will reach 100 billion yuan. The street lamp will become the key platform for
smart city interconnection IoT equipment. When the street lamp shoulders the heavy
responsibility of the entrance of the smart street lamp, the street lamp network is required to
have basic conditions such as electricity, poles, and nets. Experts predict that the market demand
for smart lighting will exceed 100 billion yuan in the next five years, bringing huge business
opportunities to the lighting technology industry.
Although the concept of smart lighting is very popular and has been applied worldwide, China's
Guangzhou, Hangzhou, Dongguan, and other places have also launched intelligent lighting
renovation projects for led street lights, but in many cities it is not widely used, the public and
The application department's perception of this technology and application is relatively lagging
behind. For example, whether the technical level of smart lighting systems is fully mature; how
smart lighting systems are integrated and compatible with other urban management systems;
how the social effects of smart lighting and actual value complement each other, these issues
also seriously affect the wisdom of wisdom in wisdom Widespread promotion and application in
cities.
With the widespread use of next-generation information technologies such as the Internet of
Things, next-generation Internet, and cloud computing, smart cities have become an inevitable
trend. In recent years, there have been frequent new policies in smart cities, and many cities in
China have set off a climax of smart city construction. The government has introduced a series of

policy measures to promote the construction of smart cities. As an important part of smart city
construction, smart street lights are expected to receive policy support in the future. The future
of smart streetlights is an important source of information collection for the Internet of Things.
Urban smart streetlights are an important part and important entrance for smart cities, which
can promote the development of smart municipalities and smart cities in the urban lighting
business, and enhance urban and municipal service capabilities.
