SMART STREET LIGHT MANAGEMENT SYSTEM FIELD

The present invention relates generally to the field of lights and electronics. More specifically, the present invention relates to smart street lights management system for intelligently controlling the functioning of the lights.

BACKGROUND

[001] Background description includes information that maybe useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[002] Streetlights form a major load for an electrical distribution system; especially in urban areas. Such vast length of roads within cities, towns and villages. Also connected to them are the national highways (total length of national highways being about 1.3 million km). Most of the streets are illuminated from evening to morning averaging about 12 hours per day within the habitations. It is well understood that some of the streets may not have vehicles or even pedestrians passing through them throughout the night.

[003] In such scenarios there is wastage of electrical energy for illumination of streets. Smart street light management would mean that sensors can sense a movement in an area and switch on the lights before the vehicle or pedestrian passes by and switch it off during no movement thus saving electrical energy.

[004] Therefore, there is a need in the art for system for intelligently turning ON or OFF of the street lights based on legitimate requirement that facilitates is saving power consumption, and seeks to overcome short-comings in the existing solutions and utilize techniques, which are robust, portable, efficient, cost-effective system.
