Components of Fluorescent Tubes

Fluorescent tubes are constructed from three basic components: a phosphor coating, mercury vapor, and electrodes. The interior of the tube is coated with a phosphor substance. The heart of the tube contains a small amount of mercury vapor. And at the ends, there are electrodes that aid in the process of illumination.

The phosphor coating is a layer of a phosphorescent substance applied to the inside of the tube. This coating takes the ultraviolet energy produced during lamp operation and converts it into visible light. Mercury vapor plays a crucial role in producing ultraviolet light. Lastly, the pair of electrodes, one at each end of the tube, are used to initiate the discharge of electricity via the mercury vapour, hence playing a critical role in the process of phosphorescence.

The Role of Each Component

Each component in a fluorescent tube plays a distinct role in the process of light production. The electrodes start the luminescence process by discharging electricity through the mercury vapor, which in turn produces ultraviolet light. This light interacts with the phosphor coating, which transforms this ultraviolet energy into visible light.

How Fluorescent Tubes Work

The lighting process in fluorescent tubes begins with the current running through the electrodes. This energy causes the mercury vapor to emit ultraviolet light, which, when it collides with the phosphor coating, is transformed into visible light. This operation process is an amalgamation of various physics concepts, including thermionic emission, ionized gas conduction, and phosphorescence.

Fluorescent tubes outshine other light sources due to their efficiency and green-footprint. While incandescent bulbs only turn about 10% of the energy they consume into light, the rest being lost as heat, fluorescent lights convert nearly 95% of the energy into light, meaning they run cooler and more efficiently.

Lifespan of Fluorescent Tubes

The average lifespan of fluorescent tubes largely depends upon their type and usage. However, most modern fluorescent tubes boast a life expectancy reaching up to 15,000 to 20,000 hours.
