Question

Who invented the tube light?

Answer 1

Tube-light:

1. Tube light is a fluorescent lamp that consists of a cylindrical tube. Dissolution of low-pressure mercury vapor converts ultraviolet rays into visible rays using coated phosphor inside the tube light. The fluorescent coating on the tube enhances the conversion of an external source of light to visible light.
2. The tube light, also known as the fluorescent lamp was invented by German inventor Edmund Germer in 1927. It is a low-pressure mercury vapor gas discharge lamp that creates visible light by using the fluorescence principle.
3. When an electric current is allowed to flow through the gas, it energizes the mercury vapor, which then uses a discharge mechanism to produce UV radiation. The ultraviolet radiation causes the phosphor coating present on the inner wall of the lamp to radiate visible light.

An illustrative diagram of a tube light is given below.
