Energy Conservation By Street Light Control

Abstract

In day-to -day life, electricity use has been an area of concern worldwide. Most of the power stations are based on the fuels that are conventional with not having many non-renewable sources available. Solar and wind are the new and renewable power sources that we should proceed on to. As we should not run into the power shortage of electricity, effective use of the available conventional and non- renewable sources should be done. The essential part of day-to-day life is Street lights that consume large amounts of electricity. The large amount of power consumption takes place by the manual operated street lighting system as they work on the given condition of from evening to early morning and heavy installation cost play the role of great disadvantage as we are in one of the developing countries. By using on/off mechanism and targeted dimming we can reduce the power consumption by 35%. The overall consumption of the energy can be reduced by 42% by doing the proper maintenance of the system. The proposed approach is the utilization of energy in an effective way that controls the automatically operating street lights when there are vehicles on the road at the evening and night time. This system is flexible and consists of different types of sensors and a controller which makes it the intelligent street lighting system and thus overcomes disadvantage [1] Key Words: Energy Conservation, Street Lighting System, ON/OFF Mechanism, Sensors and a Controller Light Dependent Resistor (LDR), Infrared Sensor (IR). 1.INTRODUCTION Energy efficiency is the key factor while designing the street lighting system. To utilize the limited power resources efficiently, an energy efficient light system is needed which can manage the usage of energy efficiently. The old lighting standards and inefficient devices the traditional lighting system is not much more reliable as it results in energy losses, automation and fault problems. In the traditional street lighting system, all the street lights are switched on at the exact time in the evening and switched off early in the morning manually which is causing Human errors and excessive energy consumption. Introduction of Automation in the street lighting system can reduce energy consumption and eliminate human errors to a great extent. To overcome these challenges, the energy consumption efficiently is done by introducing a type of automation in this system. Type of sensors such as Light Dependent Resistor (LDR), Infrared sensors (IR), Relays, Arduino uno r3, LEDs are used in this Street lighting system.
