The fluorescent lamp was invented by American engineer and inventor, George Inman, who developed the first commercially viable fluorescent lamp in 1934.
The fluorescent lamp was invented by Edmund Germer, Friedrich Meyer, and Hans Spanner in 1927. They were engineers working for the German company Osram.
The real fluorescent lamp was invented by the German-American engineer and inventor, Peter Cooper Hewitt, in 1901. His lamp used an electric arc in mercury vapor to produce a blue-green light, which was an early precursor to modern fluorescent lighting.
A capacitor in a fluorescent lamp helps to provide a stable voltage to the lamp's ballast, ensuring proper operation of the lamp. It also helps to improve the power factor of the lamp, making it more energy efficient.
Fluorescent lighting was invented by Peter Cooper Hewitt in 1901. He developed a mercury-vapor lamp that produced blue-green light when electric current passed through mercury vapor.
Fluorescent lamps contain low-pressure mercury vapor that produces ultraviolet light when an electric current passes through it. The ultraviolet light then interacts with a phosphor coating on the inside of the lamp, causing it to emit visible light. This process is more energy-efficient than traditional incandescent lighting.
