The role of street lights in the smart city of London

Way back in Roman times, this City of London has been the historic hub of the capital of UK but it is now leading its way for energy effectiveness by its smart street lights project. It is one of the top iconic buildings that you can see in London but in the evening, when the Cathedral of St. Paul is lit up of all types of distinctive shades, the radiant white dome that rested like a crown will really glow amid the skyscraper that loom on it.

There cannot be many great sights in the capital of UK than when coming from the seventeenth century church from Millennium Bridge. The Peter’s Hill, the walkway linking the River Thames trip and the 365 feet high of St Paul’s, aids to make the dramatic scenery with the series of lanterns that points down on the lane to make the warm feel during winter evenings.

It is all about making the attractive “sense of places” within the London City – the single, historic square-mile local administration place that accommodates the biggest financial centers in the globe. As the finale of a day rush hour starts in the City during the late November darkness, the lighting engineer of a local authority dimmed the lights of Peter’s Hill– which include lamp posts, bulbs fitted, and the illuminated handrails into steps – from around 60% brightness until 10%.

The smart lighting in the City of London is an iconic location with thousands of people strolling by every day and played around with those lights to have the best feeling. There used to have the strong white lights because it is a large space and it has been thought that it needed to be very bright. However, it can be dim down to 10%, still no one notices.

What is this London City smart street lighting plan?

It is not just on setting the perfect ambience for a place that is growing in significance as a visitor appeal to rival the other London districts such as Trafalgar Square, Buckingham Palace and Westminster, with the rising number of museums, restaurants, and bars. Crucially, by swapping to the (CMS) or the central management system and the LED lightbulbs that uses algorithms for automating when they switch off and on and also the brightness, it will save money and energy.

This City of London states its smart street light project – that involved the installation of 12,000 lights in between 2018-2020, already giving 60% energy savings – has been “ground-breaking” and the central pillar in making the “smart city”. The oft-used buzzword, a concept is defined through networking hardware big Cisco as the city that will adopt “scalable solutions which take advantages of the information and the communications technology to reduce costs, enhance the quality of life, and increase efficiencies.

The local authority appears to make the cost savings, like with most council in the UK and the department has been tasked also with finding the new ways of decreasing energy consumption. Lots of street lighting stock had been over 30 years of age and it is attaining the final of its useful living, so an overhaul about the whole lighting system which will embrace the new IoT or internet of things technologies.

Historically, there is a system named as Cyclo, which sent the message to switch the lights off and on. The system was modern when it first arrived in; however, 20 years on this became unsupported by the UK Power Networks. And if that was not bad enough, there had been internal pressure that will create savings, like energy.

How the smart city street lights work?

The LED bulbs are more efficient when compared with the conventional incandescent light bulbs. It is particularly effective for dimming or for spotlights – across its bridges and tunnels, streets, road signs, fountains, irrigation systems, festive lights and floodlighting. Eventually, there’ll be 15,000 lanterns – and lots of which had the heritage design – being managed by the CMS which sets color and brightness temperature to different levels depending on the time, location, and some other information that shows aspects like as when it is busiest. Even though much from it is automated, the group of electrical engineers may also intervene in making the adjustments.

IoT comes into play also as the LED light is securely linked with one another to make sure they’re in sync, and also linked up to the other sensors on the smart city network. Through communicating with the traffic signals, parking detection, noise and the pollution sensors, sewage level monitoring plus the waste sensors, this smart lighting control method is the part of the ecosystem wherein the City of London heads will measure just about all things that is going on in the public realms to recognize sticking points and to make the solutions.

The current CMS takes together 15 areas formerly controlled by this old Cyclo method on to the solo platform to provide the complete coverage. It is running at around 10%-15% capacity only, which mean it has the “massive range for the future” and should the leader wishes to pursue the new smart city scheme as technology unlocks to greater promises.

Wi-SUN Alliance task in the smart city street lights

The fairly unique challenges for the City had been the blend of the medieval streetscape and the modern skyscrapers. The history that stretches back in 50AD had been visible even among the huge towers with the comical names like The Cheesegrater, The Gherkin, and Walkie Talkie. The remains of the aged Roman wall may be spotted around Square Mile, while it is not unusual to see buildings that had been in any case 500 years old of thick walls – with the headquarters in the city, the 1411-unlocked Guildhall, and it’s the oldest church All Hallows by the Tower way back in 675AD.

There are also narrow streets but the polar opposite some meters away with the skyscrapers. Such physical barriers sits all types of headaches when this will comes to linking smart devices, however the City has discovered the means to overcome it by implementing the system designed by Itron, the energy management company and the smart city software contributor Urban Control. Itron has been the key member of Wi-SUN Alliance – the worldwide non-profit alliance of over 250 companies which aims to make the global standard for the interoperable wireless communication being used in the smart grids, smart cities, and some other bigger-scale IoT applications.

Wi-SUN is able of linking IoT-enabled street light some miles apart, is being billed as the big-scale equal to Wi-Fi – which does not work in the domain because the signal only has the short reach. It has been said that in the telco network, there is generally a recognition that any device may only last for 3-5 years but these street lights are anticipated to last up to 20 years, so the cities are searching for the different level of dedication for how longer the network connectivity can be there.

Benefits of the smart city street lights – and the future

If the City consulted the residents and the businesses, one of the query was about which element of lighting had been the most important. Security, culture and safety all scored highly, however, the most important thing was, to the astonishment of many in authority, sustainability has came out as the top after being stressed out by 27% respondents.

There is about an estimated 60% deduction in energy consumption that is already attained by the smart lighting project of the City. But expectations are bigger that to such extent when asked if IoT technology can enable the authority that will feed surplus electricity going back to grid in the same manner as the electric vehicles. It is said that there probably would not be sufficient leftover energy that will make it worthwhile.

For the cities, the street lighting is normally the largest item of energy bill. However, it can be chopped by around half with LEDs then the controls will take on another 30% off. Eventually, the lighting strategy aimed to give the smart, creative, and holistic approach in which darkness and light are better balanced that will meet both the aesthetic and the functional need.

The initial step had been made, however there are wishes to get the businesses involved too. They are asking the chain shops to dim their shopfront and also give the London City Police an access to the smart lighting controls that will improve safety in the evening. It has been said that the most “brilliant and successful work of lighting designer is normally the least noticeable”. It is something that appears to have been attainted in the walkway that leads to St Paul. It is also thought that to think differently regarding how the streets are being lighted and no lights does not have to mean total darkness.

Lights can be used to decrease crime and disorder, road danger, and also to add tourism and events through making a nice place that someone can stay in. The City really changed – and it is not just about businesses now. Aesthetics has been build and it will come all together to make that sense of place and this has given the digital platform to move forward and the next journey will come.
