The world’s top five smart cities have been ranked and the city is ranked first.

    5.Los Angeles

Los Angeles has a plan to replace old sodium vapor street lamps with smart LED lamps and plan to replace 200,000 street lamps, and the project is nearing completion. The project has saved the city more than $9 million and reduced the crime rate.

The existing street light poles are being replaced by “smart rods” equipped with 4G LTE wireless technology, which can improve mobile phone signals. Intelligent street lights can also alert the city authorities which luminaires have failed and need repairs, and can monitor and collect information on traffic conditions and parking spaces.

4.Singapore

Singapore’s goal is to become the world’s first “smart nation”. Sensors and cameras are being installed to track almost everything from traffic to waste bin capacity.

In Singapore, lighting plays an important role in the intelligent transportation network that uses road sensors, intelligent traffic lights and smart parking.

Prior to this, Philips Lighting and the Sentosa Development Bureau signed an agreement to develop a networked street light management system for Sentosa Island. In addition, the Singaporean government has partnered with UK-based Li-Fi company pureLifi to introduce Li-Fi.

3.Copenhagen

Copenhagen is one of the most sustainable and intelligent cities in the world. Its goal is to achieve carbon neutrality by 2025. Nearly half of the city’s street lights were replaced by LEDs. Many of these new fixtures have become the backbone of an ever-evolving intelligent lighting network.

When the vehicle passes through, the LED street light will turn on and then dim, ensuring that the lights will not be constantly on when it is not necessary. Sensor-loaded luminaires also capture data and analysis and can coordinate the city’s services. For example, luminaires can remind municipal authorities to empty the trash.

2.San Francisco

San Francisco has more LEED-certified buildings than other American cities, and the Connected Cities initiative allows residents to find parking spaces. Recently, San Francisco announced that 18,500 low-pressure sodium lamps will be replaced by smart LEDs.

The new LED will run through a wireless intelligent controller, allowing the city to remotely monitor the performance of a single lamp and adjust the light intensity as needed. For example, if there is a road accident, the lights may light up.

When the lamp is broken or burned out, the lamp will remind the municipal authorities to create a better life for the residents and save the city’s funds.

San Francisco’s new streetlight will be powered by 100% clean energy and, together with wireless control, will become the most environmentally friendly streetlight in California.

1.Barcelona

Barcelona’s boxes on street lamps contain well-tuned computer systems that measure traffic conditions, road pollution, crowds, and even the number of photos posted on Instagram on specific streets. Sensors installed on street lights and on the ground are also used to monitor the weather in Barcelona.

Barcelona also developed the Sentilo sensor platform as an open source, which means that city planners around the world can study Barcelona’s smart city case and will refer to it.

Smart city lighting has received more and more attention, especially with the increase in industry concentration, LED lighting industry reshuffle has entered a new stage, and China has always attached importance to the development of smart city lighting. Some industry insiders predict that during the “13th Five-Year Plan” period, the output value of smart cities will exceed 700 billion yuan. With the rapid development of the Internet of Things, it is expected that in the “13th Five-Year Plan” period, the output value of smart cities will exceed 4 trillion yuan. If we consider other upstream and downstream industrial chains, such as information technology and data analysis, the entire market scale is expected to expand to the trillion-dollar level.

Intelligent lighting is an indispensable part of a smart city. The huge market potential naturally makes the smart lighting market an unanimously recognized development direction in the industry.

With the support of policies, the hardware infrastructure for the current smart city construction is basically complete. It is understood that in 2017 China Telecom will use 800M low-frequency, wide-area to achieve Internet of Things NB-IoT coverage. It is expected that by the end of June this year, 800M-based NB-IoT network coverage will be achieved, and the coverage of urban infrastructure network will increase significantly. At the same time, operators, network companies, and equipment vendors have jointly formed the application foundation of the Internet of Things platform. In 2017, China Telecom will launch a new connection platform and service platform to provide more intelligent connectivity and empowerment capabilities to meet the needs of smart cities, a variety of application scenarios for connection and application development.
