What is the full form of CFL
CFL: Compact fluorescent lamp
CFL stands for compact fluorescent lamp. It is an energy saving lamp that consumes less power than the old incandescent lamps. It consists of a glass tube and two electrodes. The glass tube contains mixture of argon gas and mercury vapor and its inner surface has phosphor coating.
A history of CFL
For CFL there is a significant revolution in light history, the CFL is a generation of Electric Lamp. And history was produced in the 1890 Century by Peter Cooper Hewitt.
However, at the time the CFL price was supposed to be high, so the CFL was also redesigned in 1939 and later it was cheap.
The CFL is updated again in the 1976 century and cost became cheap.
How a CFL works
CFL has different mechanism to produce light than the incandescent lamps. In an incandescent lamp, electric current passes through a wire filament. It heats the filament and the filament glows to produce light. In CFL, the current passes through the tube containing the mixture of argon gas and mercury vapor. The current activates the mercury vapor which produces ultraviolet light. The ultraviolet light then excites the phosphor coating on the inside of the tube which produces visible
Types of CFL
CFL can be of two types:
1.Integrated
2.Non-integrated
Integrated: In an integrated CFL, the tube, the electronic ballast and the bayonet fitting are combined in one single unit.
Non-integrated: In a non-integrated CFL, the electronic ballast is permanently installed in the luminaire. It is not combined with the bulb so only the bulb is needed to be changed at its end of life.
Advantages of CFL
It uses less energy than incandescent lamps between 60-80 per cent.
It lasts longer than normal lamps and uses less energy, so in the long run, it’s much less costly.
It helps reduce CO2 emissions as CFL produces fewer CO2 emissions than an incandescent lamp.
CFLs are versatile and highly efficient. They arrive in a variety of sizes, shapes & capacities to suit various home decors and objectives.
They can also be conveniently used in various light fixtures including ceiling lamps, table lamps, dimmer lamps and so on.
It generates less heat because much of the energy is transferred into visible light, meaning that much less heat is transferred.
