PROJECT DESCRIPTION

In the present system, mostly the lightning-up of highways is done through High Intensity Discharge lamps (HID), whose energy consumption is high and there is no specialized mechanism to turn on the Highway light in the evening and switch off in the morning.

Its intensity cannot be controlled according to the requirement, so there is a need to switch to an alternative method of lightning system, i.e., by using LEDs. This system is built to overcome the present day drawback of HID lamps.

This system demonstrates the usage of  LEDs (light emitting diodes) as  light source and its variable intensity control, according to the requirement. LEDs consume less power and its life  is more, as compared to  conventional HID lamps.

The most important and interesting feature is its intensity that can be controlled according to  requirement during non-peak hours, which is not feasible in HID lamps. A light sensing device LDR (Light Dependent Resistance) is used to sense the light. Its resistance reduces drastically according to the day light which forms as an input signal to the controller .

A cluster of LEDs are used to form a street light. The microcontroller contains programmable instructions that controls the intensity of lights based on the PWM (Pulse width modulation) signals generated.

The intensity of lights is kept high during the peak hours, and as the traffic on the roads tend to decrease in  late nights; the intensity also decreases progressively till morning. Finally the lights get completely shut down at morning 6 am, to resume again  at 6pm in the evening. The process thus repeats.

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