What is the full form of CFL?

The full form of CFL is Compact Fluorescent Lamps. CFLs are energy-saving bulbs that use far less electricity than traditional incandescent bulbs. It consists of a glass tube and two electrodes. The inside surface of the glass tube is filled with phosphorous and includes a mixture of argon gas and mercury vapour.

A Brief History of CFL

• The CFL represents an important revolution in the history of lighting; it is a generation of electric lamps. And history was created by Peter Cooper Hewitt in the 1890s.
• However, because the CFL was expected to be expensive at the time, it was revised in 1939 and later became inexpensive.
• The CFL was upgraded again in 1976 century, and the cost was reduced.

Working Principle of CFL

CFLs have different illumination-generating paths than incandescent lamps. A wire filament conducts an electric current in bright light. It heats the thread to produce light, and the filament glows—the current in a CFL is transferred via the tube, which includes a mixture of argon gas and mercury vapour. The current causes the mercury vapour to emit UV light.

Advantages of CFL

• It consumes 60-80% less energy than incandescent lamps.
• It lasts longer than standard lamps and uses less energy. Thus, it is far less expensive in the long term.
• It helps to minimise CO2 emissions because CFL emits less CO2 than an incandescent lamp.
• CFLs are both adaptable and efficient. They are available in a range of sizes, styles, and capacities to accommodate diverse home decor and goals.
• They can also be utilised in a variety of light fixtures, such as ceiling lights, table lamps, dimmer lamps, and so on.
• It produces less heat because much of the energy is converted into visible light, resulting in significantly less heat transmission.
