neon lights notes
neon lights:
-consists of brightly glowing electrified glass tubes or bulbs that contain rarefied neon or other gases
History:
-Neon (the element) was discovered in 1898 by William Ramsay and Morris W. Travers. After they had discovered neon, they had explored neon’s many properties using an electrical gas discharge tubes. They later wrote that “the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget.”
-following neon’s discovery, neon tubes were used as scientific novelties and instruments.
-However, the scarcity of purified neon gas prompted the use of more common gases like nitrogen or carbon dioxide as the working gas.
-After 1902, George Claude’s company in France, Air Liquide, began producing industrial quantities of neon essentially as a byproduct of the air liquefaction business.
-In 1915, a US patent was issued to Claude covering the design of electrodes for gas-discharge lighting. This patent became the basis for the monopoly held in neon lighting by his company, Claude Neon Lights for neon signs throughout the early 1930’s.
-Claude had solved the two technical problems that substantially shortened the working life of neon and some other gas-discharge tubes, and gave birth to a neon lighting industry.
-He wanted to find out how to use gases like Argon and mercury vapor to create different colors beyond those produced by neon. In the 1920’s fluorescent glasses and coatings were developed to further expand the range of colors and effects for tubes with argon gas or argon-neon mixtures.
- SInce the 1950’s the development of Phosphorous for color televisions has created nearly 100 new colors for neon tube lighting
-Then around 1917 Daniel McFarlan Moore, working at GE (General Electric Company.) developed the miniature neon lamp. They don’t really use this now, so I won’t talk much about it.
