The top five most intelligent cities in the world were announced, and the city was the first to be ranked first...

The smart city revolution has not stopped its footsteps, and the opportunities for the lighting industry have matured. A few days ago, foreign media LUX rated the top five smart cities.

5 Losangeles

Losangeles has developed a plan to replace the old sodium vapor road lamps with intelligent LED lamps and plan to replace the 200 thousand street lamps. The project is close to the end. The project has saved the city by $about 9000000 and reduced the crime rate.

The existing street lamps are being replaced by "smart poles" equipped with 4G LTE wireless technology, which can improve cell phone signals. Intelligent street lamps can also alert city authorities, which lamps and lanterns have failed and need maintenance, can monitor and collect traffic information and parking space.

4 Singapore

The goal of Singapore is to be the first "wise country" in the world. Sensors and cameras are being installed to track almost all data, from traffic to carton capacity.

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

PHILPS has previously signed an agreement with the sac to develop a network of street light management systems for Sentosa Island; in addition, the government of Singapore, in collaboration with the British Li-Fi company pureLifi, aims to introduce Li-Fi.

3 Copenhagen

Copenhagen is one of the most sustainable and intelligent cities in the world, with the goal of achieving carbon neutralization by the year 2025. Nearly half of the city street lights are replaced by LED. Many of these new lamps have become the mainstay of an evolving intelligent lighting network.

When the vehicle passes, the LED street light turns bright and then darkens to ensure that the light doesn't continue to shine when there is no need.

The luminaire loaded with sensors can also capture data and analysis to coordinate the service of the city. For example, the lamps and lanterns can remind the municipal authorities to need to empty the trash.

2 San Francisco

San Francisco can be said to be the world's top leader in a smart city and near Silicon Valley, which should not be surprising.

San Francisco has more LEED - Certified buildings than other American cities, and the Internet City Initiative allows residents to find parking spaces.

Recently, San Francisco announced that 18500 low voltage sodium lamp street lamps would be replaced by intelligent LED.

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

When the lamp is broken or burned, the lamp will also remind the municipal authorities to create a better life for the residents and save the capital of the city.

San Francisco's new street lights will be powered by 100% clean energy and will be the greenest street light in California with wireless control.

1 Barcelona

Barcelona is famous for its extraordinary strength in the city of wisdom. The box on the street lamp is equipped with a carefully tuned computer system that can measure the number of traffic conditions, road pollution, people, and even the number of photos posted on a specific Street on the Instagram.

Sensors mounted on street lamps and ground are also used to monitor the weather in Barcelona.

A few years ago, Barcelona suffered a very severe drought, almost completely without water. Therefore, intelligent sensors can measure rainfall and analyze the level of irrigation on the ground. This information can be used to adjust the city's sprinkler system to save water.

Barcelona has also developed the Sentilo sensor platform as an open resource, which means that urban planners around the world can study the case of intelligent cities in Barcelona and will be referenced. (compiled: LEDinside James)
