Full Form Of CFL

CFL stands for Compact Fluorescent Lamp. It is an energy-saving bulb that consumes lesser energy as compared to conventional incandescent lamps. It has two electrodes and a glass tube that contains a mixture of argon gas and mercury vapour. The inner surface of the tube has a filling of phosphorus.

A brief history of CFL

• CFL, produced in 1890 by Peter Cooper Hewitt is a part of the generation of Electric Lamp.
• It got redesigned in 1939 in order to make it cheaper.
• It received another update in 1976 making it cheaper than before.

Working principle of CFL

CFL has multiple illumination generating pathways. The electric current travels via a wire filament in bright light and heats the thread to create light. The current transfers with the help of the tube that contains argon gas & mercury vapour and activates the mercury vapour further generating UV light.

Types of CFL

There are two types of CFL:

1. Integrated: This type consists of electronic ballast, bayonet fitting, and tube.

2. Non-Integrated: This type consists of a permanently fixed electronic ballast in the luminaire which is not one with the bulb. Thus, when expired only the bulb needs to be changed.

Advantages of CFL

• Uses less energy.
• Long-lasting.
• Cheap.
• Reduces CO2 emissions.
• Versatile and highly efficient as it comes in various sizes, shapes, and capacities.
• Convenient to use and we can use it in various light fixtures like ceiling lamps, table lamps, dimmer lamps, etc.
• Generates less heat.
