With the improvement of LED chip and driving power technology, the problems of heat dissipation, light decay and power supply that plagued LED street lamps have been solved. At the same time, the continuous and rapid price drop has greatly improved the cost performance of LED street lamps.

Domestic LED street lights have gradually replaced traditional street lights and become the main force of newly installed street lights. At the same time, the intelligent control characteristics of street lights have further strengthened the advantages of LED street lights. In the context of energy conservation and emission reduction, the penetration rate of LED street lamps has gradually increased.

According to the research data of the LED Research Institute (GGII), benefiting from the collective recovery of the domestic LED market, China's domestic LED street lamp market reached 9.46 billion in 2016, a year-on-year increase of 15.4%. By the end of 2017, the domestic LED street lamp penetration rate was close to 40% .

At present, Chinese government subsidies are weakening, and the renovation of street lamps in developed coastal areas is coming to an end. The renovation of LED street lamps in China will enter a stage of benign and stable growth, and overseas markets will gradually become the driving force for future growth.

Overseas markets will be the main driving force for the future growth of LED street lamps

Recently, Sushil Kumar Modi, Chief Deputy Minister of Patna, India, said that as part of the National Street Lighting Program (SLNP), in order to save electricity, LED street lights will soon be installed in all municipal companies and urban local agencies in the state. In addition, the government has put more emphasis on replacing traditional light bulbs with LED lights for use in street lights, because this can save 9 billion kWh of electricity across the country.

Sushil Kumar Modi also added, “Energy Efficiency Services Limited (EESL), a joint venture of public sector power companies, will soon begin installation of new LED street lights in the state. A project conducted by EESL at a site under the jurisdiction of Biharsharif Municipal Corporation According to the survey, the installation of LED street lights will save municipal institutions 131 million rupees (about 13.4 million yuan) annually."

In addition, in July this year, Chicago plans to replace 250,000 smart LED street lights in the largest smart street light program in the United States. Renewable energy company Ameresco will partner with Internet of Things (IoT) solutions provider Silver Spring Networks in a four-year infrastructure modernization program to convert approximately 85 percent of Chicago's existing streetlights to smart LED streetlights.

According to Smart Cities World, the multi-phase infrastructure modernization program will begin in the summer of 2017. It is estimated that the new LED street lights can save 50-75% of electricity compared with the existing street lights.

Silver Spring's IPv6 platform can remotely control and switch on and off street lights according to actual needs, and can also monitor and perform proactive maintenance from a remote location, which can also speed up maintenance when street lights fail.

Silver Spring executive Mike Bell said the city's streetlight renewal program will be one of the largest modernization programs in the United States to date. Mayor Rahm Emanuel's commitment to improving citizens' living standards with the latest IoT technology is extremely inspiring, and he hopes to see this initiative lay the foundation for future smart city applications.

In recent years, driven by the deepening of the globalization process and the vigorous promotion of relevant policies of LED products in various countries, domestic LED enterprises have become more and more "going out". Large-scale replacement of LED street lights in India and Chicago is undoubtedly not a good opportunity for Chinese LED lighting companies.

Smart lighting becomes the future development direction of LED street lights

At present, the smart city is gradually entering the substantive construction stage. With the acceleration of smart city construction and the wide application of new-generation information technologies such as the Internet of Things and cloud computing, the construction of smart street lights will usher in rapid development opportunities. GGII predicts that by 2020, the market penetration rate of LED smart street lamps in my country will increase to about 40%.

In the opinion of Yang Yanhui, Marketing Director of Zhongke Xinyuan, "LED lighting has now become a standard replacement for traditional street lighting in most cities in the world, and intelligent control is starting to become more and more widespread and gradually deployed together with LED lighting. All over the world Many cities are likely to replace the existing street lights with new and more efficient LED lighting equipment in the longer-term process. LED street lights connected to intelligent control can increase the energy saving efficiency by 15% on the basis of the existing 60% energy saving. Intelligent control It can realize on-demand lighting, integrate and manage existing street light resources to build an IoT platform, and manage well covers, trash cans, monitoring, billboards, etc.

It is understood that Philips Lighting has launched the CityTouch intelligent interconnected road lighting system since 2014. It has been successfully used in major cities around the world such as Los Angeles, Jakarta, Indonesia. The system is one of the important measures to promote the construction of global smart cities.

In 2017, Philips Lighting launched the CityTouch flex intelligent interconnected road lighting system again in the Chinese market. The system uses street lights as the access port of the Internet of Things, which can be connected to various smart city applications including urban emergency systems, traffic signal management systems, security monitoring systems, people flow, traffic flow, weather detection systems, etc., and fully supports smart cities. run.

Xiang Diming, general manager of professional channels of Philips Lighting Greater China, said with confidence, "With the successive landing of Philips CityTouch flex in China, we will further promote the construction of smart cities in China. In addition to street lighting, Philips Lighting will also use its own The advantages in the field of intelligent lighting in buildings, offices, industries, hotels, commerce, etc., allow more people to enjoy a more comfortable, intelligent, convenient and safe urban life."

In general, with the popularization of intelligent interconnected lighting, street lamps no longer have lighting functions, but will also create a smart city application ecosystem to help urban operation and maintenance; not only can it have significant results in energy saving and emission reduction, but also reduce crime. rate, ensure traffic safety and even enhance economic development.
