摘要： This paper implies and demonstrates a unique Smart Autonomous power and switch controlled Led Street Lighting System for Bangladesh. As we live in the age of globalization where streetlights are very much important for a city infrastructure in the crowded regions, the autonomous power and switching of these streetlights can have a huge impact in our electricity usage and minimize the wastage of electricity. Usually street light is needed at the time of sunset until the sunrise, but during peak hours (time 17:00 pm to 20:00 pm), the electricity demand is higher than electricity supply from the National Grid for many under developing countries including Bangladesh as this is the high time of excessive usage of Home Loads like Television, Air-Cooler etc. Proposed herein is a design and practically implementation of a smart autonomous power and switch controlled street light system by using stored solar energy during peak hours and light dependent resistor based energy efficient automatic Streetlight switching rather than the conventional switching operations. Besides temperature sensor and Real time clock (RTC) are being attached to display the updated time and temperature to the nearby passengers of the vehicles and walkers of the street sides. Thus, proper implementation of the proposed system will be able to be a medium for an energy efficient circuit, national grid’s power scarcity minimizer and free cost of energy and high reliability.
