At a time when smart city construction is booming, smart lamp pole screens, as innovative urban infrastructure integrating multiple functions, are gradually demonstrating their unique value. With its outstanding capabilities in information display and interaction, smart lamp pole screens have become an indispensable key element in the process of urban digital transformation. At the same time, the continuous emergence of relevant patent technologies has laid a solid technical foundation for its development, and the complex and changing market environment has not only brought rare development opportunities, but also spawned many challenges.

Smart lamp pole screens integrate multiple functions such as lighting, information release, environmental monitoring, and traffic monitoring. In public areas such as urban streets, squares, and parks, it can release information such as urban management information, emergency notices, weather forecasts, and traffic conditions, greatly improving the efficiency and transparency of urban management. At busy intersections and highway entrances and exits, lamp pole screens can display traffic flow, road conditions details, and navigation guidance in real time, helping drivers plan the best travel routes and effectively alleviating traffic congestion. In commercial areas, as an important carrier of outdoor advertising, it plays commercial advertisements and promotional information, effectively attracting consumers' attention and greatly increasing the exposure and sales of merchants. In cultural squares, tourist attractions and other places, local cultural characteristics, historical allusions and tourism information can be displayed to enrich tourists' cultural experience.

Patents occupy an extremely critical position in the development of smart lamp pole screens. From sophisticated structural design to efficient functional optimization, a series of patented technologies provide strong guarantees for the improvement of the performance of smart lamp pole screens and the expansion of their application areas. For example, some patents focus on the heat dissipation design of smart lamp pole screens. Through unique heat dissipation structures and fan configurations, they successfully overcome the heat dissipation problem of the screen in outdoor high-temperature environments, significantly extending the service life of the screen and enhancing display stability. Some other patents innovate the convenience of installation and maintenance of lamp pole screens, designing structures that are easy to adjust and disassemble, greatly reducing the cost and difficulty of later maintenance. In terms of display technology, relevant patents have promoted the research and development of high-definition, high-brightness, and low-energy display screens, enabling smart lamp pole screens to still clearly present information in outdoor strong light environments.

Globally, governments have introduced policies to vigorously promote the construction of smart cities. As an important component of smart city construction, smart lamp pole screens have benefited a lot from it. In China, since the concept of "new infrastructure" was proposed, local governments have continued to increase their investment in the construction of new infrastructure. Relevant policies clearly propose to promote the construction of new urban infrastructure based on digitalization, networking, and intelligence, and encourage the construction of smart lamp poles to accelerate the construction and deployment of 5G networks, which has injected strong momentum into the development of the smart lamp pole screen market. Under the guidance of policies, various places have carried out pilot and promotion work on smart lamp pole screen projects, and market demand has grown rapidly.

Thanks to policy support, technological progress and the continuous release of market demand, the market size of smart lamp pole screens has shown a rapid growth trend. From a global perspective, the global smart street lamp industry market size in 2020 is about US$7.51 billion, of which the smart lamp pole market size is about US$6.84 billion. It is expected that by 2024, the global smart lamp pole industry market size will exceed US$14 billion. In China, between 2018 and 2020, the scale of China's smart lamp pole market grew from 972 million yuan to 2.306 billion yuan, and reached 4.624 billion yuan in 2021, a growth rate of nearly 100% over 2020. It is expected that the market scale will exceed 16 billion yuan in 2025. With the in-depth advancement of smart city construction, the market scale of smart lamp pole screens is expected to expand further in the future.

Driven by patented technology, smart lamp pole screens have ushered in opportunities for rapid development in the current favorable market environment with their diversified functions. But at the same time, we must also face up to challenges in terms of cost, standards, and data security. Only by continuously innovating to reduce costs, improve the industry standard system, and strengthen data security protection can smart lamp pole screens play a greater role in smart city construction and achieve a broader market development space.
