Tungsten Wire Is Used in Incandescent Lamps

Tungsten wire is a key component in incandescent lamps. Here’s how tungsten wire is used in incandescent light bulbs:

Filament Manufacturing: The filament in incandescent bulbs is usually made of pure tungsten or a tungsten alloy. These filaments are long, thin thread-like structures that are usually arranged in a spiral or spiral pattern inside the glass bulb of a light bulb.

Luminous principle: The luminous principle of incandescent bulbs is based on resistive heating. When an electric current passes through a tungsten wire, it heats to a very high temperature due to resistance. This high temperature causes the tungsten wire to emit visible light, creating a lighting effect.

Spectral properties: Due to the high temperature of tungsten wire, it emits incandescent light, which means that it produces a continuous stream of light at different wavelength ranges in the visible spectrum. This brings the spectral characteristics of incandescent bulbs closer to those of natural light and therefore still valuable in certain applications, such as indoor lighting.

Temperature control: The material properties of tungsten wire allow it to remain stable at high temperatures, which is key to the proper operation of incandescent light bulbs. Tungsten wire does not melt or oxidize easily at high temperatures, allowing it to produce light over a long period of time.
