Neon Light Tubes
Neon lights have been around for over 100 years and have provided very effective ways to communicate messages in a colorful and attractive manner. We'll discuss some of the history involved in the creation and evolution of these lights.
The first neon lights were produced from glass tubes filled with a special type of gas that would glow when electrified. They were called Geissler tubes.
The Geissler tubes were originally developed in the late 1800's. It was possible for them to emit different colors of light depending on the type of gas used within the tubes. The use of Geissler tubes was somewhat limited, however, because the gas tended to leak out of the tubes and their lighting effectiveness dropped as the tubes lost pressure.
An improvement was made to the Geissler tube with the introduction of the Moore tube. These tubes used nitrogen or carbon dioxide to provide the lighting effects. They also trapped the gas more effectively so that the pressure could remain more constant. Beginning in the early 1900's, the use of Moore's tubes was a common way to provide this special kind of lighting.
Neon lights evolved when it was found that glass tubes that were filled with neon gas that was then electrified produced a very pleasant glow. This type of lighting was used to illuminate a sign for a brand of French liquor and it was later used in other types of signage.
