Lamps - Flourescent, Incandescent, LED, HID or Oil?
Could you imagine not having lamps at home? - no fluorescent
lamps, study lamps, ceiling lamps? I guess not. Lamps or bulbs
are so much a part of our society that we seldom give them much
notice. However, we cannot imagine living without them.
Lamp comes from the Greek word "lampas", meaning torch, lamp, or
beacon. Any equipment that gives off light for some duration to
be used for lighting is called a lamp.
In the modern world, lamps are defined as the replaceable part
of a luminaire. This contraption transforms electrical energy to
both visible and non-visible electromagnetic energy.
The first thing man had to develop was fire. After developing
fire, he must have thought, "Hey, I have to put this in my den
so it will provide light and warmth to it." And so he took a
piece of flaming firewood from the bonfire and took it inside
his home. Thus the first "lamp" in the form of a torch was
created.
Man's next problem was how to get those things to last longer.
Over the span of time, he developed numerous ways of prolonging
this light. Some of the ancients used beeswax, some used olive
oil.
Soon complex means of lighting homes and streets were used. In
the late 19th century, oil lamps lined the streets of England to
provide lighting throughout the thoroughfares.
Then came the famed perseverance of Thomas Edison. After tiring
days of back breaking work, Edison invented the incandescent
lamp. And the world was changed forever.
Today the world is a big glowing lamp. Cities are bathed in
streams of light from buildings, street lamps, car lights and
home lighting. Because of technology, lamps today can last
longer, can light brighter, and can be used more conveniently
than before.
So Many Lamps, So Little Time - Kinds of Lamps
1. Oil based lamps
These are the old fashioned lamps that burn on oil, wax or other
base. They are now commonly used to provide atmosphere to the
home or to light areas where there is no electricity.
2. Incandescent Lamp
The incandescent lamps have come a long way. These lamps are
used to provide lighting in many countries. These lamps are hot
and give off light that is, in brightness, somewhere between
candlelight and sunlight. Halogen lamps are a version of
incandescent lamps that give a brighter light more akin to
sunlight.
3. Flourescent Lamps
Fluorescent lamps give off light that is cooler than its
incandescent cousin. They are very energy efficient and are easy
to install and do not generate too much heat. They are very
popular nowadays. Another good thing about these lamps is that
they last longer than incandescent lamps.
4. HID Lamps
High-intensity discharge lighting are specialized lamps that are
very powerful. They were first used for streetlights and are
very energy efficient. They typically convert energy to light at
an astounding 8:10 ratio.
5. LED Lamps
LED lamp technology is very promising because they give off a
very bright light for very little electricity and do not heat as
much as the other lamp technologies. However, they are still
expensive to manufacture for lighting. They are, however,
already being used for electronic displays, and accent lighting.
Another upside is that they are extremely durable, LED lamps
could last 100,000 hours or more! This makes the future of lamps
very exciting.
