Services, business activities, people's livelihood, environmental protection, public safety and other urban needs to make intelligent optimization and timely response, forming a smart city form with sustainable development, convenient, efficient, green and safe.

1.2 Domestic Smart City Process

On January 29, 2013, the Ministry of Housing and Urban-Rural Development announced the first batch of national smart city pilot lists.

On April 10, 2013, the Smart City Creation Task Book Weaving Training Conference organized by the Building Energy Conservation and Technology Department of the Ministry of Housing and Urban-Rural Development was held in Beijing.

On August 29, 2014, with the approval of the State Council, the Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Public Security, the Ministry of Finance, the Ministry of Land and Resources, the Ministry of Housing and Urban-Rural Development, and the Ministry of Communications issued the "Guiding Opinions on Promoting the Healthy Development of Smart Cities."

2015 is the first year of implementation of the scale of smart city construction. The author believes that it is also the starting point for China's urban construction to begin to overtake the developed countries.

1.3 Smart City Architecture

The overall architecture of Huawei Smart City Solution is shown in Figure 1.

Huawei believes that smart city is a complex "giant system" involving investment and financing, top-level design, integration, operations, business applications, and ICT infrastructure. Therefore, only the enterprises in each link can do their own good things in their respective fields, in order to promote the benign development of the smart city ecosystem, and provide a smart city overall solution that meets the needs of customers and evolves. In the smart city field, Huawei provides technical support and after-sales service focusing on ICT infrastructure and solutions.

Figure 1 Huawei Smart City Solution Overall Architecture

The author understands that there are countless information collection terminals and sensing systems in the four levels of perception, network, data and application in the smart city system architecture; urban communication network and urban Internet of Things are emphasized in the network layer; data layer is included in the sensing layer. Including cloud data processing center and public information service platform, big data support platform; including the brain of smart city in the application layer - smart city management operation center, central nervous system - smart government, smart city management, safe city, digital environmental protection, Digital gardens, intelligent transportation, smart medical care, smart education, intelligent lighting and other subsystems. Due to the implementation of the “12th Five-Year Plan for Urban Green Lighting Planning”, urban lighting facilities are the most complete, complete and digitally-managed urban infrastructure in the entire smart city system architecture, and can carry other Perceive and apply subsystem equipment to achieve the core functions of smart cities (see Figure 3). Therefore, smart lighting naturally exists in both the sensing and application layers of the smart city system architecture (see Figure 2).

Figure 2 Smart lighting in the smart city system architecture

2.1 Smart lighting is based on intelligent lighting

Intelligent lighting refers to the use of artificial intelligence, wireless communication data transmission, intelligent information processing, Internet of Things, Sensors, control systems and other technologies, so that the lighting facilities have color temperature, brightness, color, soft-start of the light source, timing control, Scene setting and other functions, and meet the requirements of the predetermined lighting standards to meet the needs of different personalities, while at the same time according to the program feedback problem lighting system engineering. Smart lighting is a more advanced stage of intelligent lighting.

2.2 Smart lighting is lighting non-lighting

IEC-SC34E--AC4 is defined as: smart lighting, smart lighting is a fixture equipped with sensing, communication and processing components; intelligent lighting system, intelligent lighting system is one or more smart lighting with one or more controls Combination of devices.

The definition of Feile sound is: Wisdom lighting is a core concept of the Internet of Things with “lights, nets and clouds”. The core product is “a lamp”, which uses LED lights as an integrated sensing terminal and integrated working terminal. The focus is on arranging "one network" for perception and transmission, and finally integrating it into the management background "a cloud" to create data clouds, service clouds and smart clouds. Construct a set of lighting based on intelligent lighting, use the training and ecosystem, buy the "1+X" comprehensive application, build a new model of urban currency infrastructure construction, realize the multi-party profit, and guide the smart city construction into the sustainable development stage (see Figure 4).

Huawei believes that the network of hundreds of millions of lighting facilities will be the beginning of the construction of the municipal Internet of Things. Starting from municipal lighting, intelligent equipment such as traffic management, environmental monitoring, municipal management, and municipal lighting will be connected to create a fully connected municipal Internet of Things. The future of “smart cities” can be constructed.

The author believes that: intelligent lighting is the perfect combination of software and hardware, material and consciousness, technology and art, appearing in the form of urban hair and skin, and directly through the systematic engineering of the central nervous system of smart cities. Smart lighting is based on human planning and design, covering all lighting, carrying smart city perception layer and application layer multiple subsystems, capable of human-computer interaction, expressing emotions, and conforming to the development trend of nature. Wisdom lighting has its own programming language and lighting language. The lighting language expresses joy and sorrow in the process of depicting history, culture, art, humanity, and the emergence and emphasis of the universe, the world, the ancient and modern city, and the human landscape. It can be discovered, perceived, and experienced by people of different national boundaries, different skin colors, different races, different languages, and different backgrounds, thus resonating. Wisdom illumination not only satisfies the different needs of light in the universe, but also subverts the universe and the world of color and shape that can be seen by human eyes. The so-called "seeing the five elements are empty, the color is empty and color" (see Figure 5).
