Design And Construction Rechargeable AC Lamp Using Energy Bulb

ABSTRACT

Nowadays, because of low energy or power consumption, low heat emission, low cost, the portability, wider application, energy saving bulb are highly used than florescent lamp. For instance, energy bulbs use about half the wattage of fluorescent lighting, about 6 watts of power versus 14 watts of power for a CFL light bulb. For an LED bulb’s lifespan, about 340 kilowatt hours of electricity is used. Fluorescent bulbs used over 60,000 hours (6 bulbs) will use around 840 kilowatt hours of electricity, also The light focuses on where the bulb is pointed rather than bathing the wider area in light. Because of all these advantages makes energy bulb highly applicable in rechargeable lantern design.

This work is on Researchable AC lamp which is a rechargeable source of light that is generated from an AC sources and stored in a rechargeable battery which is to be used during power outage using an energy saving bulb as the lighting device. It also serves as immanency sources of light mostly used when there is failure from out public power supply (P.H.C.N).

1.1                                          INTRODUCTION

A lantern 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.

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.

1.2                             OBJECTIVE OF THE PROJECT

The objective of this work is to design a 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

1.3                          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.

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:

• 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.

 ADVANTAGES OF RECHARGEABLE LANTERN

1. 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.
2. 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.
3. 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.
4. The right rechargeable camping lantern offers a number of ways to keep it up and running. These can be charged via AC plug

BENEFITS OF ENEGY LIGHTBULBS IN RECHARGEBLE LANTERN
Long-lasting – energy bulbs last up to 10 times as long as compact fluorescents, and far longer than typical incandescents.

Durable – since energy bulb do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken. Because they are solid, energy bulbs hold up well to jarring and bumping.

Cool – these bulbs do not cause heat build-up; energy lamp produce 3.4 btu’s/hour, compared to 85 for incandescent bulbs. Common incandescent bulbs get hot and contribute to heat build-up in a room. Energy lamp prevent this heat build-up, thereby helping to reduce air conditioning costs in the home.

Mercury-free – no mercury is used in the manufacturing of  energy lamp.

More efficient – Energy light bulbs use only 2-17 watts of electricity (1/3rd to 1/30th of Incandescent or CFL). Energy bulbs used in fixtures inside the home save electricity, remain cool and save money on replacement costs since energy bulbs last so long. Small energy flashlight bulbs will extend battery life 10 to 15 times longer than with incandescent bulbs.

Cost-effective – although energy bulbs are initially expensive, the cost is recouped over time and in battery savings. Energy bulb use was first adopted commercially, where maintenance and replacement costs are expensive. But the cost of new energy bulbs has gone down considerably in the last few years. and are continuing to go down. Today, there are many new energy light bulbs for use in the home, and the cost is becoming less of an issue.

Light for remote areas and portable generators – because of the low power requirement for energy, using solar panels becomes more practical and less expensive than running an electric line or using a generator for lighting in remote or off-grid areas. Energy light bulbs are also ideal for use with small portable generators which homeowners use for backup power in emergencies.

CHOOSING AN ENERGY LIGHTBULB

Many different models and styles of energy bulbs are emerging in today’s marketplace. When choosing a bulb, keep in mind the following:

• Estimate desired brightness – read the package to choose desired brightness level. You can use wattage to compare bulb illumination, for example, a 9W energy is equivalent in output to a 45 W incandescent. However, the new method for comparing bulbs is lumens. Lumens is the measuse of perceived brightness, and the higher the lumens, the brighter the bulb. The FTC has mandated that all light bulb packages display lumens as the primary measure for comparing bulbs.
• Choose between warm and cool light – new energy bulbs are available in ‘cool’ white light, which is ideal for task lighting, and ‘warm’ light commonly used for accent or small area lighting.
