Smart Street Lighting System: An Energy Efficient Approach

Today electricity is a major concern worldwide and most of the power generation stations are based on conventional fuels like coal but we have limited sources of these non renewable fuels. So as to minimize the dependence on these sources, we have to move on to new and renewable sources like solar and wind, etc. However proper usage of electricity could also be one of the effective tools for saving the conventional fuels. Street lights are one of the most crucial parts for public lighting systems which consume a major part of the generated electricity. The conventional or manual controlled street lighting system has demerits like high power consumption, high cost and absence of effective monitoring system. This paper describes an energy efficient approach of smart street lighting system, which can automatically control the switching and intensity of street lights based on surrounding light intensity. Basically a smart street lighting system is a flexible street lighting system consists of various sensors and a controller which make it an intelligent street lighting system. This system can effectively overcome the demerits of any conventional street lighting system.
