How smart street lighting is improving cities

Johannesburg. Paris. Beijing. Oslo. Jakarta. Dublin. The street scenes vary, but cities worldwide share an imperative to improve the efficiency, costs, and operations of their streetlights. Outdoor lighting control solutions are helping these cities, and others, to do more with their strategic but costly lighting assets.

I t’s estimated that as much as 40% of city energy budgets are spent on outdoor lighting, and that a single street light can emit 200 kg of CO 2 each year. Increasingly, cities need to save energy or do more with less energy, reduce carbon emissions, lower operating and maintenance costs, and com ply with tighter government regulations. In addition, many are exploring Smart City applications and the use of lighting to boost safety for both drivers and pedestrians. For all these reasons, better lighting and light ing control top most cities’ priority lists. Recently, hybrid wired/wireless network products have been pioneered that enable cities to mix and match their communications media. For instance, cities can use wired power line communications (PLC) for tunnels or remote stretches of highway and wire less radio frequency (RF) where wired solutions are cost-prohibitive. In this way, cities can, for the first time, achieve 100% lighting coverage with a

single solution.

The results Cities that have implemented web-based lighting control systems report results that include: • Average energy savings ranging from 28% to 62% – with up to one-third of the savings attributed to adaptive lighting control. • Ability to free up energy according to demand. • Lower ongoing maintenance and inventory costs through remote identification of lamp failures, preventive maintenance, and the use of lower-wattage, longer-lasting street lights. • Improved public safety and satisfaction due to reduced lamp downtime, less light pollution, and better overall lighting quality. • Reduced CO 2 emissions. • Rapid detection of electricity theft and leakage. • Preservation of historical and decorative lights, while still attaining the benefits of modern
