The first street light was installed in Newcastle, England, in 1879. In 1905, the first electric street light was turned on in Bengaluru, India. The Maharaja of Mysore decided to illuminate the city streets by harnessing the power of the Cauvery Falls. Since then, street light technology has advanced significantly, with a global installed base of smart street lights approaching 20 million units.
Previously, street lights were manually operated. An operator was required to manually turn on the street lights when it became dark and turn them off when the sun rose. As a result, time, energy, and money were all squandered. To solve this problem, a clever solution was required.
Many smart solutions have emerged as a result of technological advancements such as Artificial Intelligence (AI) and the Internet of Things (IoT). Smart street lights can be installed with cameras and sensors. These cameras and sensors can detect nearby movement and light intensity and send a signal to nearby street lights to turn on or off, resulting in a safe environment for pedestrians.
The smart street light solution is part of the Integrated Building Management System (IBMS) solution from Radius Synergies International Pvt Ltd. Street lights can be controlled and managed wirelessly using this system. The client can control the street lights remotely using a smartphone or tablet. This helps them save time, energy, and money.
Smart street lights automatically adjust to the intensity of the ambient light. The smart street lights detect the intensity of the lights around them using LUX sensors. It dims and brightens automatically based on the intensity of natural light at any time of day. When the natural light is sufficient at sunrise, it automatically dims the light, and when the natural light is insufficient at sunset, it automatically brightens, saving both energy and money.
Smart Street lights in a city improve traffic safety, the pedestrian environment, and the architectural, touristic, and commercial output of the city. Smart street lights can reduce energy consumption by nearly 50% and operational costs by 33%.
Previously, street lights required regular patrolling to detect any defective street lights. The patrolling officer then manually reported it to the organisation in charge of the street lights. It would take several days for the lights to be repaired or replaced and was costly too. However, the maintenance team no longer needs to patrol the streets because they now receive detailed notifications with any malfunction, including possible defect analysis and required materials.
In the future, street lights may be outfitted with a variety of gadgets and devices, such as an Electric Vehicle (EV) charging station for users to charge their EVs, smart screens to display important information to pedestrians and drivers, and an emergency SOS button and telephone to contact authorities in the event of a danger or when in need of assistance.
Smart street lights have enormous potential. Cities are growing and becoming smarter, the world is becoming more city-centric, and people are becoming more aware of the growing need to become environmentally efficient, and smart street lighting plays a significant role in this shift.
