Adaptive Street Light Controlling For Smart Cities

摘要

Street lights is one of the basic amenities provided by local municipal body in every town or city. In India, ON-OFF control of street lights is operated manually. Therefore, it is most likely that controlling is not done on time. Also, fixed timings are not suitable in all seasons. Due to this street lights remain glowing for extra time or do not switch on when required. Sometimes, local climate conditions demand switching off street lights. Hence the present practice leads to lot of inconvenience & power wastage. Both issues are addressed here by designing automatic as well as adaptive method of street light control. The system takes into account sunrise & sunset timings, ambient light conditions, dust or mist factor at the location. This new system enables the street lights to adapt the daytime schedule to operate automatically with nanowatt technology based microcontroller and sensors for LED street lights. Hence the new method controls street lights intelligently. This work presented under this paper, along with efficient LED based system, the dimming of light & automated operating principle improves life of street lamps. This serves the purpose of saving energy additionally. The total energy savings can be up to 60% to 65% more in contrast to existing lighting system. This adaptive street light controlling system for smart cities offers simplest solution to save the energy.
