With the development of the "Internet +" era, smart cities have begun to integrate the new information technologies such as Internet of things, cloud computing and big data integration, integrate the key information of the urban operation system, and make intelligent responses to the needs of urban services, public safety, energy saving and environmental protection, so as to realize the automation and intellectualization of urban management and services. In this good trend, street lamp intelligent lighting began to develop well in a new situation.

As the leader of building a smart city, street lights are dense and extensive urban infrastructure. Intelligent street lamp energy conservation and environmental protection, management and control science is an important part of urban public lighting system and smart city. In order to achieve the goal of energy conservation and emission reduction, highlight the regional cultural characteristics, speed up the pace of investment, lighting enterprises and municipal government jointly promote the LED green energy conservation lighting transformation project in this area.

In order to facilitate the travel of the general public, the municipal landscape management bureau also realizes the automatic switching time of the lights through the light control system of the intelligent management platform for street lights according to the seasonal and weather changes. At the same time, at 10 o'clock every night, the system will automatically reduce the energy consumption of intelligent LED street lamps in urban areas by 20%, and reduce the energy consumption of LED street lamps by 30% again in the early morning, so as to achieve full-time energy saving.

Road lights should use light energy reasonably to prevent glare. The light emitted by the device shall be irradiated along the required angle and fall on the road surface to present the specified figure. The light distribution shall be uniform, the road surface shall be bright and the glare shall be small. In order to reduce glare, light distribution can be controlled above the maximum light intensity. According to the road section form, width, vehicles and pedestrians, the road lamps can be arranged symmetrically on both sides of the road, staggered on both sides, arranged on one side and suspended in the middle of the road.

After the intelligent control of LED street lights, it can not only save energy and reduce emissions, reduce energy consumption, but also reduce the amount of maintenance. It is estimated that more than 7 million yuan can be saved every year. Among them, more than 6.5 million yuan was saved for electricity, nearly 500000 yuan for maintenance and consumables, 13000 tons of carbon dioxide and 430 tons of sulfur dioxide were reduced, benefiting hundreds of thousands of people.

The above is the trend of street lighting intelligent lighting under the "Internet +" era. We do not know if we have any further understanding of the development of intelligent street lamps.
