With the development of technology and the emergence of the concept of ubiquitous computing, the early vision of the so-called “smart city” not only connected the environmental elements related to the city, but also integrated most elements within the city into automation. Smart street lamps are also a part of smart cities. Many cities around the world choose smart street lamps as the starting point for the development of smart cities. Because smart street lamps are transformed from traditional street lamps into street lamps with high energy efficiency and remote monitoring and control, they have considerable market growth potential in smart cities. Since the intelligent street lamp has been converted to LED, about 50% – 60% of the energy cost can be saved, so the cost can be recovered in a short time.

Application cases of intelligent lighting and analysis of current challenges

1、 Main service areas of intelligent lighting:

By detecting the failure return of the basic device, we can know the location that needs to be repaired, and the road maintenance vehicle will be sent for maintenance at that time. Therefore, the cost of prior inspection by the road maintenance vehicle can be saved. Due to the advantages of reducing energy consumption, short-term cost recovery and reducing labor maintenance costs, intelligent lighting has become the first choice for cities to enter the wisdom stage. Its development overview is briefly described as follows:

(1) Transportation: it adopts intelligent transportation solutions and an architecture supporting the future global mobility-as-a-service (MAAS) transportation.

(2) Public safety: it emphasizes the ability to quickly detect potential criminal activities.

(3) Public health: installing sensors on fixed devices can send warning notices faster and report the real-time air quality status in the metropolitan area, so as to facilitate the subsequent prevention of movement.

(4) Connectivity and other services: through the partnership between mobile network operators and other manufacturers, it will accelerate the development of urban broadband and promote the plans of other smart cities.

2、 Challenges faced by intelligent street lamps

(1) Energy saving: in the business case of this kind of urban plan, the main axis is to replace street lamps with LED lamps and control brightness, so as to reduce energy use. However, after considering the cost of replacing lamps, it is not so easy for government units to directly achieve the cost saving effect of intelligent street lamps. However, the introduction of intelligent street lamps can identify the location of street lamp faults in real time. At that time, manpower can be effectively sent for repair, which can reduce the time of inspecting lamps and lanterns, and greatly save costs through more efficient maintenance.

(2) Interoperability: Although the world is committed to standardizing intelligent street lamps, their interoperability is still obviously insufficient. In fact, the incentives for manufacturers to move towards a fully standardized ecosystem are quite insufficient. In addition to nodal pricing, there is little opportunity to implement differentiation in today’s situation. In the procurement process, the government must consider the property service life of intelligent street lamps and the long-term viability of participants in the ecosystem. Software update services and security vulnerabilities may have a serious impact on urban infrastructure.

(3) Adjacent services: from 2016 to 2019, the application cases of providing smart city services by using the poles and lamps of intelligent street lamps showed significant growth. The industries benefiting from the rise of intelligent street lamps include: mobile network operator (MnO) and communications service provider (CSP).

3、 Application cases of intelligent lighting:

(1) Jakarta, Indonesia

Jakarta’s first step towards a smart city is to upgrade nearly 90000 street light sources from xinnuofei signify (formerly known as Philips Lighting) to energy-saving LED lighting equipment, and conduct network control through “interact urban lighting management software”. It takes only seven months to replace all of them, with an average of 430 network light points replaced every day, This is currently the world’s fastest intelligent street lamp transformation project.

Each light point uses lighting management software to send the effectiveness data to the government’s lighting office through the existing power line communication (PLC) cable network. Through data collection, the government can continuously monitor the overall lighting infrastructure of the city and carry out remote management according to different needs. Due to the successful results of the setting of intelligent street lamps in the first stage, the project has moved towards the planning of the second stage, and it is estimated that the number of intelligent street lamps will be expanded to 150000.

(2) Hong Kong

Singapore Technology Engineering Co., Ltd. (st Engineering) will promote the intelligent street lamp solution to Hong Kong and carry out the conceptual verification test of multi-functional street lamps in Hong Kong. It is expected to install customized multi-functional street lamps in Kowloon East, the pilot of Hong Kong’s smart city. These street lamps will be combined with the telecommunications network to form the architecture of the Internet of things. The sensors on the street lamps can collect various information of the city in real time, including weather, air quality, air temperature, parking space, flow of people and vehicles, etc.
