TUNGSTEN LAMP Meaning and
Definition
-
A tungsten lamp, also known as an incandescent lamp, is a type of electric light bulb that uses tungsten filaments to produce light. It is one of the most common and widely used sources of lighting in both residential and commercial settings.
The lamp consists of a glass bulb that is filled with a small amount of inert gas, typically argon or nitrogen, to prevent the filament from oxidizing and burning out. Inside the bulb, there is a tungsten filament that is heated to extremely high temperatures when an electric current is applied. The high temperature causes the filament to glow and emit visible light.
Tungsten is the metal of choice for the filament due to its high melting point and excellent electrical conductivity. The filament is typically coiled or twisted to increase its surface area, thereby maximizing the amount of light produced.
Tungsten lamps are valued for their warm and comfortable light output, as well as their ability to accurately render colors. However, they have relatively low energy efficiency compared to other lighting technologies, as a considerable amount of energy is wasted in the form of heat. As a result, tungsten lamps have been gradually phased out in many countries in favor of more energy-efficient options like compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs).

Etymology of TUNGSTEN LAMP
The word "tungsten lamp" is derived from the metal tungsten and the type of lighting technology it is used in.
The term "tungsten" comes from the Swedish words "tung" meaning heavy and "sten" meaning stone. The metal tungsten was first discovered in the late 18th century, and it was given this name due to its high density compared to other elements.
A "lamp" refers to a device that produces light, typically with the help of a filament or other source of illumination.
Therefore, a "tungsten lamp" specifically refers to a type of electric lamp that uses tungsten as a filament to produce light when an electric current passes through it. These lamps are commonly known as incandescent lamps, as they operate by heating the tungsten filament until it becomes white-hot and emits visible light.
