  • White LED (Light Emitting Diodes) substitutes HID lanterns in road illumination system to add on dim element. 8051 family’s micro-controller is bring into play to control the power by growing pulse width transformed pointers that impels a MOSFET to swap the Light Emitting Diodes accordingly to accomplish most wanted function.

    Block Diagram of Automatic Street Lights Intensity Control

    Automatic Street Lights Intensity Control block diagram


    In the current system, maximum lightning over the freeways is completed through HID (High Intensity Discharge lamps), the energy utilization of HID lamps/lanterns are high. The intensity of HID lamps cannot be controlled, in harmony to the necessity, therefore there is a requirement to swap to a substitute way of illumination system i.e., by making use of LEDs. This lighting system is constructed to conquer the disadvantages of High Intensity Discharge lamps.

    This lightning system exhibits the utilization of the Light emitting diodes or LED’s as the source of light and its intensity control is variable which can be altered as per the requirement. LED’s use a lesser amount of power and its life span is good, in comparison to the old HID lanterns/lamps. The more vital and motivating characteristic is that the intensity of LED’s can be controlled as per the requirement throughout non-peak hours which is not possible with HID lanterns/lamps.

    A bunch of LEDs are brought into play to structure a street light. The micro-controller includes planned instructions which are used for controlling the intensity of lanterns based on Pulse width modulation (PWM) produced indicators. The lights intensity are kept soaring all through the peak hours, because the street traffic have a propensity to reduce slowly during late night hours, the intensity of the traffic also declines gradually till sunrise. Finally it’s totally shuts down at dawn, and it’s all over again restarts at 6pm during the dusk. The course of action is repeated.

    This theory in future can be improved by incorporating it with the solar energy panel, which exchanges the solar energy into parallel electrical energy, and this electric power is utilized to light up the freeway lanterns/lights.

      i hv a little bit confusion about the auto intensity control idea which is mentioned in the title; since the intensity of street lights is controlled according to real time clock only…,

    5. There is no reason or advantage in “auto intensity.”

    6. Sir…..
      can we use retroreflector to detect vehicles during night??? if it is possible then plz explain me .

    7. “can we use retroreflector to detect vehicles during night??? if it is possible then plz explain me ”

      Show me the project you have built first

      • Sorry sir, I am planning to design a circuit which will detect vehicles in the night by retroreflector sheet.
        when light focused on them they reflect back so that by using LDR I can detect something is coming.
        that is my idea ….is it work properly.Shall plz give me your valuable suggestions to me..?

    8. sir pls give me pin digram for dis project

      This project can be done with a 555 IC and a few parts.
      This project costs $120 USD from EdgeFix. It is a ripoff.

    11. Sir., can have the detsiled pin diagram.., its components & its values

    12. sir can i have the detailed circuit diagram & and its components values of auto street light intensity control project

    13. Colin Mitchell Colin Mitchell says: on April 27, 2015 at 3:03 pm

      sir can i have the detailed circuit diagram

      It costs $120 USD

    14. sir plz send me the source code of auto intensity control of street light
