PROJECT DESCRIPTION

White Light Emitting Diodes (LED) replace HID lamps in street lighting system to include dimming feature. An Arduinoboard is used to control intensity automatically by developing pulse width modulated signals that drives MOSFET to switch a set of  LEDs accordingly to achievea desired operation.

This system is built to overcome present-day drawbacksof HID lamps. This system demonstrates the usage of LEDs (light emitting diodes) as light source and its variable intensity control, as per requirement.

LEDs consume less power and their lifetime is more,as compared to conventional HID lamps Moreover LED intensity can be controlled as per therequirement during non-peak hours, which is not feasible in HID lamps.

The Arduino boardcontains programmable instructions that control the intensity of lights based on PWM (Pulse width modulation)signals generated. The intensity of lights is kept high during peak hours.Asthe traffic on the roads tend to decrease slowly in late nights, the intensity also decreases progressively until morning. Finally the intensity completely shuts down in the morning at 6 A.M, and again resumesat 6 P.M. in the evening andthis process is repeated.

This concept in future can be enhanced by integrating it with a solar panel that converts solar intensity into corresponding power, and this energy is used to feed the highway lights.
