Neon lights are derived from the English word "neon light." The word "neon" is actually a transliteration of "neon," and it has become the standard term.
The development of neon lights can be traced back to the research of British physicist and chemist Michael Faraday on gas discharge. When an electric current passes through a gas containing a small number of positive and negative ions, it is influenced by ultraviolet rays, cosmic rays, and trace amounts of radioactive substances. Under a sufficiently high applied voltage, the current moves and collides with neutral gas molecules, causing the neutral molecules to ionize, thus multiplying the number of ions. The passage of current through the gas is accompanied by a glow discharge phenomenon, also known as luminescence. The color of the glow varies depending on the gas. Faraday's theory and experimental achievements laid a solid foundation for the development of neon light technology.
