Since the invention of electricity by Michael faraday, 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.
An electronic mobile lamp is a portable source of light that is generated from a D.C sources of supply. This D.C sources is a battery that can also be charged when its current and voltage is used.
It also serves as immanency sources of light mostly when there is failure from out public power supply (P.H.C.N). The project is to see how one can construct a source of high without really generating is from an A.C source.
This project is 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.
An electronic mobile lamp operates on rechargeable batteries which can be charged, with the adaptors included, whether at home or while on the move by car. The 27 LED's provide excellent levels of lighting to 40 lumens and up to 20 hours operating time on full charger making it an ideal camping companion.

1.1 INTRODUCTION
An electronic mobile lamp is a portable lighting device or mounted light fixture used to illuminate broad areas. Lanterns may also be used for signaling, as torches, or as general light sources outdoors. Low light level varieties are used for decoration. The term "lantern" is also used more generically to mean a light source, or the enclosure for a light source according to Oxford English Dictionary, 3rd ed, 2005.
Rechargeable lights are very useful electrical gadgets and are quite popular, too. During a power failure these portable lights are able to instantly illuminate through battery back up and never allow us to stumble in the darkness. Although you will find a variety of them in different shapes and sizes in the market, but building your own emergency light at home can be a totally different experience. It will not only help you to create a quality design but also will acquaint you to the technical aspects of the unit. Besides, you also get an opportunity to customize the circuit as per your own needs according to (Velayudhan, S.K., 2003).
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is to design a portable lighting gadget that can be powered directly from ac mains or lamp holder for the purposing of charging the battery which later used whenever there is power outage during the night. The rechargeable battery used is rated 6v.
1.3 PROBLEM STATEMENT
In the last decade candle stick and kerosene or gas lantern were used as a source of light for mankind but the problem of using candle are numerous such as it cost effective, weighty, convenient and unsafe to environment and human health. Because of these disadvantages led to the invention of rechargeable lantern. Rechargeable lantern has the following advantages over candle stick, kerosene or gas lantern (Sustainable Village, 2007):
- Compared to a gas lantern, a rechargeable lantern is light as a feather. Gas lanterns are typically made of glass and have metal canisters that add weight that rechargeable lanterns are able to eliminate. The lighter the weight of the lantern the more versatile it can be, whether it be to light up the card table or take it for your bathroom break.
- With the variety of lanterns like liquid fuel, gas, or even candle, a rechargeable lantern is an alternative that offers ease of use. All you have to do it switch it on and light is available. This saves you from having to remember to bring other items on the trip like gas to fuel the lantern or matches to light the candle. If you happen to have kids joining you on a camping trip, spoiler alert: they will more than likely drop a gas lantern and break the glass. Skip to the good part and allow them to carry a rechargeable lantern without worry.
- Lanterns with flames always come with a small risk of causing a fire, but rechargeable lanterns don’t require a babysitter. By avoiding a kerosene powered lantern, you can eliminate potential fumes.
- Rechargeable lantern can be charged via AC plug, DC plug, dynamo crank function, or with solar panels.
1.4 SIGNIFICANCE OF THE PROJECT
This system charges when there is power supply, the energy is stored in a rechargeable battery which is to be used when there is power outage. The lasting of the stored energy depends on the capacity of the rechargeable battery (Roy, J., 2000).1.4 LIMITATION OF THE PROJECT
The device is powered directly to ac mains, and can easily get burnt when high voltage is experienced in the mains if it is not properly regulated.
1.5 APPLICATION OF THE PROJECT
Rechargeable lantern is used in many places such as (Roy, J., 2000):
- In school library, hall and labs
- Churches
- Workshop
- Homes, etc
All for the purpose of illuminating of such environment. They highly choose because of its simplicity and safety, that is, it can be charged, hanged, and continues with your adventures into the night.
1.6 ADVANTAGES OF RECHARGEABLE LANTERN
- Lightweight. Compared to a gas lantern, a rechargeable lantern is light as a feather. Gas lanterns are typically made of glass and have metal canisters that add weight that rechargeable lanterns are able to eliminate. The lighter the weight of the lantern the more versatile it can be, whether it be to light up the card table or take it for your bathroom break.
- User-friendly. With the variety of lanterns like liquid fuel, gas, or even candle, a rechargeable lantern is an alternative that offers ease of use. All you have to do it switch it on and light is available. This saves you from having to remember to bring other items on the trip like gas to fuel the lantern or matches to light the candle. If you happen to have kids joining you on a camping trip, spoiler alert: they will more than likely drop a gas lantern and break the glass. Skip to the good part and allow them to carry a rechargeable lantern without worry (Sustainable Village, 2007).
- Safe. Lanterns with flames always come with a small risk of causing a fire, but rechargeable lanterns don’t require a babysitter. By avoiding a kerosene powered lantern, you can eliminate potential fumes.
- Convenient. The right rechargeable camping lantern offers a number of ways to keep it up and running. These can be charged via AC plug
