Thesis Abstract

<p> 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.<br>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.<br>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. <br></p>

Thesis Overview

<p> </p><p><strong>1.1 INTRODUCTION</strong></p><p>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.<br>It has really helped us in the powering of our system both in our domestic homes and industries.<br>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)<br>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.<br>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.</p><p><strong>1.2 OBJECTIVE OF THE PROJECT</strong></p><p>1. Rechargeable lamp helps one to understand and how a D.C source can generate a source of light.<br>2. It helps one to understand how to design a portable lamp<br>3. To see how a source of light will be generated in the absence of electricity or power supply</p><p><strong>1.3 SIGNIFICANCE OF THE PROJECT</strong></p><p>1. It helps me mostly in the night to read effectively<br>2. It helps me also to use light even to read absence of power in the house as an emergency.<br>3. 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).</p><p><strong>1.4 THE REPORT LAYOUT</strong></p><p>I went a long way, in term of reading browsing and other kind of researches, in order to see how this project will be accomplished (Designing of a rechargeable lantern).<br>The following are the various step I passed through in order to accomplish this project.<br>1. Theories and models relevant to rechargeable lantern<br>2. The component involved<br>3. The design<br>4. The circuit diagram<br>5. The implementation and testing<br>6. The result<br>7. The cost analysis<br>8. Recommendation<br>9. Conclusion</p> <br><p></p>
