The paper aim is to modeling “Energy Efficient Smart Street Lighting System”. This system reduces the issues arises in the contemporary avenue lighting system, and finds a way to keep energy greater than 15% of energy consumption in India and 19-38% global. In doing so the first step is LED lights instead of conventional lamps, secondly light by demand, not by the clock, thirdly solar street light. Maximum road safety with minimum operational costs, this is the guiding idea behind “Intelligent street lighting”. Intelligent street lighting systems can think for themselves and reduce energy costs. LDR, IR and Microcontroller are the essential components of the system. The light dependent resistor (LDR) varies its resistance according to the light falls on it. When an obstacle is coming nearer to the highway lighting system, it will be detected by IR sensor and certain light will be in ON condition. The AT89S52 microcontroller enables more dynamic and faster control. A solar panel made of crystals is used to charge a 6V rechargeable battery. Additional battery charger circuit is provided for emergency applications. The paper is designed for LED based Street Lights with an auto-vehicle detection that uses solar power. This prototype can be installed on toll roads at toll collection stations and on roads with sharp curves.
