Energy conservation helps in using energy in effectivemanner. Application of advanced technology and improved operation and maintenance practices contributes towards energy conservation. Smart streetlight framework is an essential piece of the smart city, which represents 10- 40% aggregate power utilization in the city. In this paper the energy audit report is presented for streetlights in the industry and also presented various energy conservation measures with the help of sensors and automation. It was observed that Passive Infra-red (PIR) sensor helps a lot in saving energy where movement of people is low. Keywords:- Energy conservation, Light Dependent Resistor (LDR), Passive Infra-red (PIR) sensor, Photocell Sensor, Streetlight. 1. INTRODUCTION Street lighting is provided for people during the evening and night hours for movement of vehicles and persons. Street lighting is switched ON for 10-14 hour in India. In municipal area it is the responsibility of local governing body to provide the proper illumination for commuters. In industry it is the responsibility of industry owner to provide the sufficient light at various working places and on streets for workers and other staff to reduce the rate of accidents in the industry. For industry, providing sufficient illumination is a costly affair due to high electricity tariff for industry. Researchers has published various research papers to suggest reduction in energy bill for lighting by energy conservations or by use of better and efficient fixtures for illumination. Garcia-Llera et. al in their paper proposed new designs for sending the light in proper direction with desired intensity. Staggered arrangement for street lighting with advantage of Power LED’s efficiency, is suggested. Considering real geometry for City of Oviedo in Spain, two experimental lamps design for street lighting were proposed to validate the established methodology [1].Gul Shahzad et. al proposes the new concept of street lighting based on traffic-flow using LED for energy optimization. The low power ZigBee mesh network is used to provide maximum energy efficiency based on adaptive traffic on the road. Smart LED lights with wireless network offers improved reliability, reduced cost, and more user satisfaction [2]. Serge Kalinowsky and John Martello in their paper done analysis for various combinations of F40-Tl2, F96-T12, and compact energy-savings fluorescent lamps by applying voltage less than rated voltage [3]. C. Subramani et. al presented the project based on automated streetlamps with less consumption and provides sustainable output. Sodium vapour lamps replaces with LEDs which detect the vehicle traffic and control the lighting of the lamps [4]Basil Paul and Vedavyasa Kamath in their papers presents the lighting audit results with Journal of University of Shanghai for Science and Technology ISSN: 1007-6735 Volume 22, Issue 12, December - 2020 Page-1319 D.O.I - 10.51201/12502 https://doi.org/10.51201/12502
