The construction of smart cities covers a large amount of basic data, such as basic geographic information, planning results, transportation, integrated pipelines, policies and regulations, population, etc. How to store and use these data becomes an urgent problem for policy makers. The development of new generation information technologies such as cloud computing and Internet of Things has promoted the rapid development of big data, provided decision support for the government, and provided assistance to enterprise organizations and business processes, and has a tremendous impact on cities, transportation, medical care, and education.For color, the world around us is always changing. The time, weather, and season determine how we feel a certain moment in time. Sometimes, the use of colored outdoor lighting to evoke the feeling of a certain daytime environment is to achieve the "layout scene" through the night flooding outdoor lighting project. Temperature also has a lot to do with color: warm light means heat, and blue light gives a cold feeling.

Big data and smart outdoor lighting fixturesBig data, or massive data, refers to a collection of data that cannot be crawled, managed, and processed by conventional software tools over a period of time. Smart city is a high-level form of urban informationization based on knowledge society innovation that fully utilizes information technology in all walks of life in cities.For the construction of smart cities, it can be divided into government-led construction and enterprise-led construction. Government-led construction focuses on the collection, management, analysis, monitoring and sharing of basic data, and the construction goals are smart government and public platform; The leading construction focuses on industry applications, and the main construction targets are smart industries such as smart transportation and smart medical care. Although the focus and construction objectives are different, the two are a coordinated and organic whole. The government-led construction focuses on the construction of the basic platform, while the enterprise-led construction focuses on practical applications.As an important part of smart city construction, outdoor lighting fixtures serve traffic safety and people's production and life. The urban outdoor lighting system is distributed in every corner of the city to upgrade the existing outdoor lighting fixtures, which can quickly and easily realize the construction of a wide-ranging information-aware network, realize intelligent lighting of street lamps, diversification of information collection and information processing. Faster.
