Neon Lights – Signs

Neon lights as signs have been used in advertisements for about a century. The history of these lighted signs dates way back to the 1910s. The light works by applying electric current to its gas which is found in the middle of the tube. This article discusses how neon lights work and how they are unique from other kinds of lighting.

Lights made of neon were initially invented by Georges Claude, a Frenchman. He found out that when electric current is applied to neon gas it illuminates. What happens in neon lights is that the neon gas gradually becomes ionized as electric current goes through it, and it eventually emits light. If enough current goes through the neon gas, the light then becomes constant.

Neon signs are a great way to market and bring attention to a business. We have all seen neon-lighted signs in the windows of restaurants, taverns, and a multitude of other businesses. They are instantly noticeable because they are lit and vibrantly colored. They look beautiful and are memorable. Just think of the beauty of Las Vegas lights.

Not all signs made of neon lights are made entirely from neon. Actually, some do not even have neon at all. It was discovered that other gases like argon, helium, xenon and krypton had equal reactions as the neon when electrified. They however had different colors when they glowed. Helium turned pink, neon turned orange, argon turned light blue, krypton turned light purple and xenon turned dark purple. When they were mixed together in varying quantities, they produced a lot of different colors of glow. They all took the name ‘neon light’ since neon was first discovered before the other noble gasses.
