Fluorescent
Lighting
Need of invention
Seeing or listening
the word ‘Lighting’ we
think about lamps, bulbs invented by Thomas Edison which
are known as incandescent lights. These lights have a very
thin tungsten filament, which is inside the glass sphere,
and they work on electricity. The filament inside the light
bulbs are so thin that they offer a bit resistance to the
electricity where the resistance coverts electrical energy
to heat. So the disadvantages of these bulbs are that heat
waste lots of electricity. Keeping this point in view and
many others there was a necessity of inventing fluorescent
lightings. So Alexendre E. Becquerel invented the phenomena
of fluorescence for lighting that saves energy and also saves
atmospheric pollution.
How fluorescent lightings are more efficient?
Fluorescent lightings produce light in a different manner.
At both the ends of the fluorescent tubes there are electrodes
and a gas containing argon and mercury vapor inside the
tube. Now a stream of electrons flows from one electrode
to the other through the gas and bump into the mercury
vapor atoms floating inside the fluorescent bulbs. The
mercury atoms becomes excited and when they return back
to the before state i.e. the unexcited state they release
ultraviolet photons which collide with the phosphor coating
inside the bulb and this phosphor creates the visible light.
So here the phosphors are used to produce light.
Hence fluorescent bulbs are more efficient
than incandescent bulbs since it produces less heat and saves
more energy. These bulbs can produce between 50 and 100 lumes
per watt. Use of fluorescent lighting reduces the cost of
electricity comparatively to incandescent bulbs.
Uses of fluorescent lightings
Fluorescent lightings are used in schools, companies, homes,
stores, dressing rooms, etc. Now-a-days fluorescent bulbs
are more efficient to use since it saves a lot of energy
and electricity and comparatively cheaper than the normal
bulbs that are used. Its biggest advantage is that switching
on and off continuously will not affect the fluorescent
bulbs as it affects the normal bulbs. Best manufacturers
are Circular fluorescent bulb manufacturer. Other main
manufacturers are the Compact fluorescent light bulbs,
which have many different types of bulbs with different
shapes and the required watt to be used.
