Energy Efficient Smart Street Lighting System in Nagpur Smart City using IoT-A Case Study

Street Lighting is an important factor for ensuring safety in the city and instilling a sense of security in the mind of the citizens. But the cost associated with it is quite high which is borne by the local municipalities. Recent development in the lighting devices has seen a paradigm shift in the types of devices used which has led to little savings in energy consumption, but a lot remains wasted. Smart street lighting is a cost-effective solution in an urban environment which compromises of advance wireless communication techniques, low cost LED lights and additional sensors which controls the intensity of light. This new system has significant cost and energy savings over the conventional switching ON-OFF method. This paper presents a case study of smart lighting system in Nagpur smart city where one of the goals was to reduce the carbon footprint by reducing the energy consumption. This was achieved by replacing the outdated 320 street luminaries and integrating additional 63 LED lights with motion detection smart lighting system. The deployed intelligent street lighting system of Nagpur smart city has drastically reduced the energy consumption by approximately 55 % per month, while maintaining the lighting norms for the pedestrians and vehicles.
