How Does a Fluorescent Lamp Work?
A fluorescent lamp is a long glass tube that is filled with a special kind of gas. This gas is called mercury vapor. The inside of the tube is frosted with a powdery chemical called “phosphors.”
When the lamp is turned on, electricity passes through the mercury vapor. This makes it glow with a dim blue light. The blue light shines on the phosphor powder, causing the powder to glow with a cool, bright light. This glowing light is known as fluorescence.
The standard fluorescent lamp was developed for commercial use during the 1930’s. Fluorescent lamps are widely used to produce bright, low-cost lighting in factories, offices and schools.
The idea of the fluorescent lamp had been around since the 1880’s however it took steady work over the decades to finally create a working commercially viable model. This work was done by many, not one single inventor.
