How Smart Lighting Shapes Efficient, Safe and Sustainable Cities 

Smart lighting – adaptive, automated lighting technology – has emerged as a critical tool for creating more efficient, resilient and liveable urban environments.

The history of smart lighting traces back to the early 2000s. Advancements in LED (Light Emitting Diode) technology presented significant advantages over traditional lighting sources. This includes lower energy consumption, longer lifespan and enhanced controllability.

With the emergence of the Internet of Things (IoT) in the 2010s, the benefits of smart lighting have truly escalated, utilising advanced sensors, network connectivity and automation to further increase energy efficiency as well as improve safety and functionality.

Furthermore, the network of connected lighting offers the potential to deliver a range of other services beneficial to the efficient management of cities, such environmental monitoring. 

Energy efficiency 

At the core of intelligent lighting systems is the ability to adjust lighting based on real-time conditions.

While traditional street lighting systems operate on a fixed schedule, often resulting in unnecessary illumination during periods of low activity, smart lighting dynamically adjusts to actual needs of the current status.

Sensors detect movement, ambient light levels and even traffic conditions. In turn, this enables the energy-saving LED lights to dim, brighten, or turn off completely in response to the immediate environment.

This adaptability not only reduces energy consumption (for example the city of Jakarta reported energy savings of up to 70%), but also extends the lifespan of the lighting fixtures. Moreover, the ability to remotely monitor and manage lighting infrastructure enables proactive maintenance, minimising downtime and further enhancing energy efficiency. 


Public safety 

Smart lighting enhances public safety by improving visibility in urban areas.

Well-lit streets and public spaces have been shown to deter crime and increase pedestrian traffic after dark, contributing to a safer and more vibrant city. Smart lighting systems can be programmed to respond to specific events. This extends to increasing brightness in response to an emergency call or lighting up pedestrian paths when sensors detect movement.

Furthermore, smart lighting systems can integrate with surveillance cameras and other security devices, providing valuable data for law enforcement and emergency response teams.


Intelligent city management 

Smart lighting can foster environmental sustainability and management by reducing energy consumption and greenhouse gas emissions. It can also be used for data collection for urban planning purposes, providing insights into air and noise quality, pedestrian and vehicular traffic patterns, as well as other metrics that inform decision-making process.

There are examples of cities that use the networked infrastructure for broader applications. For example, electric vehicle charging, parking availability notification, and public information display.

The deployment of smart lighting additionally often coincides with the implementation of other smart city initiatives, such as intelligent transportation systems and waste management solutions 

The challenges 

However, the deployment of intelligent lighting systems is not without challenges. These include privacy concerns, cybersecurity, interoperability and initial implementation costs. These must be addressed to unlock the full potential of smart lighting in shaping the cities of the future.
