Various Bulb Types And Their Working • 03.07.10
Incandescent bulbs, Compact Fluorescent (CFL) bulbs, Fluorescent bulbs and Halogen bulbs are some of the bulb types that are available in market. In below mentioned paragraphs, you will get brief description about all these.
First of all, we will talk about incandescent bulbs or say standard light bulbs. These bulbs are commonly used by people from long back and are very cheap to purchase. In market, you can easily find them in different colors, sizes and shapes. One biggest drawback of using them is that they consume a lot of electricity in heating the filament present inside these bulbs. When this filament gets properly heated, it causes the bulb to glow.
Compact fluorescent bulbs are the most energy-efficient bulbs available, using about two-thirds less energy than standard incandescent bulbs to provide the same amount of light and lasting up to 10 times as long. CFLs now come in a variety of shapes, styles and light output. Just like regular bulbs, they can be used in standard sockets.
These bulbs have a mercury gas-filled tube and ballast, which is the electrical component. An electric current from the ballast flows through the gas, which produces invisible ultraviolet (UV) light. The UV light hits a white coating (phosphor) inside the bulb and changes it into light that you see. Fluorescent bulbs don’t use heat to create light, which is why they are more energy-efficient and cooler to the touch than regular bulbs.
Standard fluorescent bulbs are very similar to compact fluorescent bulbs. Fluorescent bulbs also help in saving electricity and are very durable but these bulbs can not be fixed in standard sockets. One more disadvantage of using fluorescent bulbs is that you can not get many choices in it. These bulbs are available in linear, circular and U-shape.
The method through which light is produced by a fluorescent bulb is similar to the method used by compact fluorescent bulbs. One point where they differ is that in fluorescent bulbs you require separate ballast.
Halogen bulbs could be found in market in different shapes and sizes such as A-line and reflector style. The light generated by them is also clear and bright. These lights have high initial cost but are long lasting.
Technique of light production in a halogen bulb in quite same as incandescent bulbs but the halogen gas in halogen bulbs let the tungsten to get back on filament after evaporation. This little difference gives a long life to halogen bulbs unlike incandescent bulbs.
