Neon Signs


By: Janelle Murakami

Neon signs are a cool, modernize way to light up any space or room. They were introduced in the early 20th century, yet it was not until 100 years later that these light fixtures were able to be made at home.

Neon lights are made by filling hollow glass tubes or bulbs with rarefied neon or other gases, depending on what you want your final color to be.

Neon lights are a type of cold cathode gas-discharge light.  By putting electrodes at either end of the tube and pumping electricity into it, various gases create different colored lights, with hues further accentuated by any tinting on the actual glass itself.

This relates to engineering because it uses technology and you go through a process of making it in every step.
