The smart city revolution did not stop, and the opportunities in the lighting industry have matured. Recently, foreign media LUX has identified the top five smart cities.
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.
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.
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 can be described as one of the world's top smart cities, and is located near Silicon Valley. This should not be surprising.
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.
Barcelona is known around the world for the extraordinary power of its smart city. The boxes mounted on the street lights contain carefully tuned computer systems that can 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.
A few years ago, Barcelona suffered a very severe drought, almost completely without water. Therefore, smart sensors can measure rainfall and analyze ground irrigation levels. This information can be used to adjust the city's sprinkler system to save water.
Barcelona also developed the Sentilo sensor platform as an open source, which means that urban planners around the world can study Barcelona's smart city case .
