PROJECT DESCRIPTION

White Light Emitting Diodes (LED) replaces HID lamps in street lighting system to include dimming feature. A microcontroller of 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 lightning system i.e., by using LEDs.

This system is build to overcome the present day drawbacks of HID lamps. This system demonstrates the usage of the LED’s (light emitting diodes) as the light source and its variable intensity control, according to the requirement.

LED’s consume less power and its life time is more, as compared to the conventional HID lamps. The more important and interesting feature is its intensity can be controlled according to the requirement during non peak hours 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 street lights based on the PWM (Pulse width modulation) signals generated.

The intensity of lights are kept high during the peak hours, as the traffic on the roads tend to decrease slowly in the late nights, the intensity also  decreases progressively till morning. Final it completely shuts down at morning 6, and again resumes at 6pm in the evening. The process is repeated.

This dynamically changing intensity ON/OFFconcept in future can be enhanced by integrating it with the solar panel, which converts the solar intensity into corresponding voltage, and this energy is used to feed up the highway lights.

Q & A
Q:  What is auto intensity control?
A:  Automatically controlling the intensity of street light according to the peak traffic hours in the night time and completely getting switched off at the day time based on time control is known as auto intensity control.
Q:  Which kind of street light is used in this project?
A:  A string of white LEDs are used as street lights and also white LEDs are better than the conventional HID lamps used as street lights.
Q:  What is the family of microcontroller used?
A:  Here a 40 pin microcontroller from 8051 family is used.
Q:  What is the concept used in this project?
A:  PWM technique is used in this project.

I came to know about Edgefx through Google while I and my friends were searching for the projects and we used projects as a keyword in Google to find Edgefx.I decided to buy a kit because of the Delivery facility. I like the complete kit.Yes the kit delivered on time with the right components.I purchased the project through online.No Improvements required.

Manish kumar, Mumbai on 2nd June, 2015, 11:33 AM

Yes the kit delivered on time with the right components.All my technical queries were cleared.It’s was a good while building the project on my own.Yes I will recommend in future.
