PROJECT DESCRIPTION

White Light Emitting Diodes (LED) replace HID lamps in street lighting system to include dimming feature. A microcontroller of the 8051 family is used to control the intensity by developing pulse width modulated signals that drives a MOSFET to switch the LEDs according to achieve desired operation.

In the present system, mostly the lightning up of highways is done through High Intensity Discharge lamps (HID), whose energy consumption is high. Its intensity cannot be controlled according to the requirement so there is a need to switch on to an alternative method of lighting 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 the light source and its variable intensity control, according to the requirement. LEDs consume less power and its life time is more, as compared to the conventional HID lamps.

Most  important and interesting feature is its intensity which can be controlled according to the requirement  using PWM by the push button provided which is not feasible in HID lamps.

A cluster of LEDs are used to form a street light. The microcontroller contains programmable instructions which controls the intensity of lights based on the PWM (Pulse width modulation) signals generated. The intensity of lights can be adjusted accordingly by the push-button provided to change the PWM.

.This concept in future can be enhanced by integrating it with the solar panel, which can convert the solar intensity into corresponding power to feed  the highway lights.
