According to this article, using different types of lighting can enhance room aesthetics and functionality.
The Basics of Fluorescent Lamps and Their Mechanism
Fluorescent lamps work differently from incandescent bulbs. They don’t have a glowing filament; instead, they use a process called gas discharge. Inside the glass tube is a small amount of mercury vapor and an inert gas like argon. When electricity passes through these gases, it creates ultraviolet light. This UV light then hits the phosphor coating inside the tube, transforming into visible light.
The process starts with the lamp’s electrodes, which are located at both ends of the tube. These electrodes emit electrons when charged with electricity. These high-energy electrons collide with the mercury vapor particles. The collisions excite the mercury atoms, making them produce ultraviolet photons. These UV photons are invisible to the human eye but are crucial in the light-emitting process.
One of the key components is the phosphor coating on the inner walls of the tube. This coating is why you see light rather than UV rays. When UV photons hit the phosphor, it gets excited and emits visible light. The specific type of phosphor used determines the color of the light, ranging from cool white to warm white.
