Development Of Street Lighting Dimmer

Abstract

A Street light is a light installed at the edge of a roadway to illuminate the side of the road. The history of lighting streets and roadways is ancient, with evidence that many communities in the Ancient World encouraged citizens to keep outside lights burning through the course of the evening for navigation and safety. The earliest formal street lights operated as a municipal service were gas lights, which were hand lit by a crew of people every evening. Eventually, gaslighting was replaced with electric lighting, and street lights today are usually fully automated. The purpose of a street light is not to illuminate the roadway; at night time, drivers should be using headlights, which will illuminate the road for them. Street lights light up the side of the road, alerting drivers to potential hazards and situations which they need to be aware of. They can also be used to signal the presence of an intersection, so that a driver can be prepared for cross traffic or get ready to turn onto a side street. For this final year project we will make a Development of LED Street Lighting Dimmer. It is basically used to save electrical consumption on street light automatically by the help of LDR (Light Dependent Resistor) Module, Infrared Module and LED. It is designed to performing & increase the efficiency of street lighting even more during in nights. It consists of an ARDUINO UNO R3 microcontroller which construct with LDR and Infrared module, so it will make the street light dimmer if there is no vehicle. This is the best way of managing a street light system to be electrical save. By applying the proposed system, streets can be illuminated with lower power consumption lamps, low operating cost, and environmentally friendly it is best used without any disadvantage as compared to the current street lighting system. Two main objectives of the proposed project for this semester are:

• To switch the light automatically using LDR module. • To save electical consumption by using infrared sensor which is increase the brightness when there is a vehicle passing by and dimmer the brightness when there is no vehicle on road/street.

For this project, the model of street light is made with Arduino microcontroller. The model uses LED to save the electrical consumption and consists of a module that will detect the presence of vehicle on the road.
