Street lights can not only achieve simple lighting, but also control the lighting time and brightness according to the weather and people flow; the lamp post is no longer just supporting street lights, it can also help people make choices to avoid congestion, and even become connected to WiFi and transmit data. Entrance... This is the help and convenience that smart lighting brings to people in the field of streetlights. In fact, with the construction of smart cities, from indoors to outdoors, smart lighting is gradually illuminating every corner of urban life, transforming the city from management to service, from governance to operation, from fragmentation to synergy. .
Smart lighting highlights frequently
In recent years, the state has attached great importance to energy conservation and environmental protection. With the rapid development of LED semiconductors and new generation digital communication technologies, the smart lighting market has gradually developed in the construction of smart cities, and the highlights are frequent everywhere.
According to experts, many cities across the country have introduced smart lighting projects. Among them, intelligent street light poles have become the data acquisition nodes and application realization carriers of smart cities. Zhejiang Province has built the first smart lighting project based on standardized NB-IoT (narrowband Internet of Things technology). Hangzhou Smart Lighting Project is to install NB-IoT narrow-band IoT communication module on the city's streetlight pole, and use China Telecom's NB-IoT network to integrate every street lamp in the city into the unified urban street lamp management center platform. The intelligent street lamp technology can individually control each street lamp and adjust the brightness of each street lamp at any time, thereby achieving the goal of intelligent control of urban street lamps and energy saving and emission reduction. At present, there are only 170,000 light poles in the main city of Hangzhou, which are located in every corner of the city, like the capillary of the city. It is an excellent node for collecting and transmitting urban information data.
Beijing Rare Earth Lighting Technology Co., Ltd. combines local anti-terrorism and stability needs in Xinjiang, and uses the wisdom light pole as a means to realize many functions of road monitoring, weather forecasting and security control on the basis of traditional lighting pole lighting, and fully realize the Beidou satellite multi-system. The real-time data collection, transmission, analysis and other systems have established a successful application model in Hami. At the same time, through the multi-functional advantages of smart light poles, it promotes the interaction of urban public security, public transportation, environment, roads and other multi-sectors, forming a large database of smart sharing.
In recent years, Chongqing has also been a highlight in smart lighting. Some of Chongqing's road sections are equipped with the latest Internet multi-color temperature anti-fog LED full intelligent street lights and management system. The system can automatically collect weather visibility, temperature, fog and other data around the clock. According to the changes of different seasons and temperature, the color temperature and brightness of the light are automatically adjusted to greatly improve the power saving rate and safety. According to Dr. Huang Xiaowei, director of the R&D Center of Chongqing Optoelectronic Information Research Institute, at present, the Institute of Optoelectronics is using the "intelligent lighting" and "lighting bar as the carrier of the Internet of Things" as a breakthrough to create a smart city in northern Fujian. It can save 20% of electricity consumption every year.
At the same time, Philips announced the operation of the intelligent interconnected lighting system in China's first near-zero energy demonstration building. In the first building of the Philips PoE (Ethernet Power Supply Technology) smart connected office lighting system in the country, employees can pass the intelligence. An application on your phone that personalizes the level of light and darkness. The energy consumption of lighting accounts for only 16% of the energy consumption of the demonstration building, and the lighting energy consumption per unit area is only one quarter of that of similar buildings. Philips hopes to push the smart connected lighting system to the smart home, and it can connect with all the devices such as doorbells, TVs and music players in the home, which will provide more convenience and help for daily life.
Smart lighting prospects can be expected
Experts pointed out that although wisdom lighting has developed in recent years, the overall situation is still in its infancy, and many unfavorable factors still restrict the rapid development of the industry, which needs to be solved.
Fan Huiwen, deputy dean of the China Electronics and Information Industry Development Research Institute, pointed out that the main problems of the intelligent lighting system are low cost performance, high price, large investment, and insufficient wisdom. The energy saving effect is limited and the functions are relatively simple. He suggested that the future development should be popularized from high-end communities, high-end hotels and tourist attractions, industrial parks and new urban areas, gradually increasing the scope of application and industry scale, forming a virtuous circle of mutual promotion of technology, application and industry.
Zhang Liming, secretary-general of the Smart City Development Committee of the China Association for Regional Economics, believes that most smart lighting companies are currently unable to identify the pain points of urban demand, and the solutions are expensive, cost-effective and practical, and there are many pseudo-intelligent concepts that make the project difficult. Landing, it is difficult to form a revolutionary industry in the short term.
According to industry insiders, in the implementation of smart lighting, it is difficult to carry out unified management in the aspects of municipal fees and facilities investment, and it is difficult to carry out the unified management of municipal fees and facilities. Marketization. To this end, the person suggested that through the capital operation methods such as PPP (public-private partnership model) and EMC (contract energy management), the administrative monopoly management can be broken, and financial monitoring methods can be introduced to achieve a high degree of integration between the government and enterprises for the benefit of urban development.
In view of the development trend of smart lighting in the future, Fan Huiwen believes that there are two basic trends in the future development of smart lighting systems. One is more intelligent, and the lighting should strengthen the functions of intelligent sensing, remote meter reading, dimming and ultra-low power consumption. It can control lamps and lanterns in a wide range of ways, allowing simple lighting to evolve into a city landscape. Second, it is multi-functional. In addition to lighting functions, it can also provide wireless access, environmental monitoring, data collection, commercial advertising, traffic instructions, festival celebrations, etc. Many functions can add more business models, and let a single lighting develop into an information network operation platform.
As an important part of smart city, smart lighting uses the city sensor network and power carrier technology to connect the street lights in the city to form the “Internet of Thingsâ€, and uses information processing technology to process and analyze massive sensing information. Intelligent needs and intelligent decision-making support for various needs such as people's livelihood, environment, and public safety have made urban living lighting reach a "smart" state. Therefore, in the implementation of smart lighting, although there are still shortcomings, its market prospects are extremely broad and deserve the industry's expectation.
