ABSTRACT

Man has been so used to electricity that he cannot do without it. The absence of electricity causes a lot of sadness in our daily lives. Due to this reason I decided to work on a by rechargeable lamp as my project.
The project is to see how one can construct a source of high without really generating is from an A.C source. I decided to write on this project in order to saw how I can implement it during and after school for home and marketing purpose.
This project is a lamp that was a 6v rechargeable battery to generate light which is very useful to man both at home and otherwise. It is a stem that is very portable and very effective mostly t might after which it has been charged.

CHAPTER ONE

1.0 INTRODUCTION

Electricity and electronic has done a lot of good to our society. Sometimes I imagine how the entire world would have look like without light or electricity. Electricity has a lot of advantages both in our homes and industrial uses. Some of then include cooking washing of cloths (laundry) milling and as sources of light e.g rechargeable lamps. Rechargeable lamp is one important devoice that comprises the use of electricity and electronics. Due to it great importance to the society at large decided to use it as my project topic.

When I say electricity and electronic someone may be imaging if there is any difference among the two. But the answer is yes. This is because electricity does not involves component like diodes capacitors transistor etc but electronic is the embody of this discrete component to from a working circuit. Note that electricity is just the stepping down of voltage by using a transformer to pass current and voltage to the circuit only.

Nevertheless my concentration is on rechargeable which serves as a sources of light in our homes in the absence of electricity from our public power supply.

Electricity is of great importance to our lines and has done a lot of good to our present day society it is something we cannot do without, if we are to advance technological and otherwise. 
It has really helped us in the powering of our system both in our domestic homes and industries. 
But in our own country (Nigeria), there has been always these problems of lack of power and fluctuation in power supplied, which made me to see how I can design a circuit that can generate a source of light, eve in the absence of electricity or power from the general source of power supply (PHCN)
I decided to design and write on a rechargeable lantern, which I always use a my source of light in the absence of the major source of light. Ti is a portable lamp designed to be recharged using an alternating current (A.C) and to generate a source of light using a direct current (D.C) source. 
When the system is charging using an A.C. source, the lamp will never come on which is the source of light. This is because I used light emitting diode (LED) as my source of light and it is a D.C component
.


1.1 OBJECTIVES OF RECHARGEABLE LAMP

To enjoy light even in the absence of electricity from the general power supply.

To generate sources of light using a d.c circuit

1.      Rechargeable lamp helps one to understand and how a D.C source can generate a source of light. 

2.       It helps one to understand how to design a portable lamp

3.      To see how a source of light will be generated in the absence of electricity or power supply

4. It helps me mostly in the night to read effectively 
5.  It helps me also to use light even to read absence of power in the house as an emergency. 

6. The benefits that are derivable from it is more than the maintenance factor, I attribute it such as (no fuel required as compared with A.C generators).


1.2 SIGNIFICANCE OF RECHARGEABLE LAMP 

It helps us to enjoy light even in the absence of electricity it is very economical


1.3 MOTIVATION

   A lamp rechargeable  as the name suggests is for turning ON and OFF the lamp automatically without the need of human interventions. It senses the light intensity from surroundings and find whether its day or night. And it automatically turns ON when the surrounding is dark and it turns OFF when it receives light from surroundings. A sensor called LDR is used to detect the light intensity. This project finds wide outdoor applications in streets, gardens and public places where it finds difficulty to appoint a person to operate the lights.

LEDs (light-emitting diodes, or solid-state lighting), are ultra-efficient, have an extended working life, significantly reduce CO2 emissions even compare to compact fluorescent bulbs, slash power bills and minimize replacement (i.e. maintenance) costs. Many of the modern designs simply slot into the same fixtures and fittings as incandescent bulbs, but their flexibility also means that designers are producing ever more intriguing and versatile lighting possibilities.


1.4 AIM AND OBJECTIVES

Aim

          To construct automated  lamp rechargeable

Objectives

·         To construct  lamp rechargeable

·         To construct  lamp rechargeable with 12 LEDs arranged in a square pattern.

·         To construct  lamp rechargeable that use LDR to switch on automatic.

 

1.5 Scope OF THE construction lamp rechargeble

The scope of this construction is to construct a Lamp using ' which consist two circuit, In constructing the project, the circuit was sub divided into two sub circuits viz;

v   Power supply Unit

v   LED circuit/display


1.6 STATEMENT OF THE PROBLEM

The popularity of lamp rechargeable lights is driving an increase in light pollution worldwide, with dire consequences for human and animal health, the issue isn't just the  lights themselves, which are more efficient because they need fearless electricity to provide the same amount of light.
