Piccadilly Circus, London, 1962. Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure.
A Nixie tube (English: / ˈnɪk.siː / NIK-see), or cold cathode display, [1] is an electronic device used for displaying numerals or other information using glow discharge. calculator. Inside a broken Nixie tube. The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols.
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
Neon lights are exceptionally long-lasting due to their vibrant colors and the ability to craft tubes that function for decades. This longevity is crucial to their economic viability, given the labor-intensive creation process. Interestingly, smaller diameter tubes produce brighter neon light, but also have higher resistance.
Tritium radioluminescence is the use of gaseous tritium, a radioactive isotope of hydrogen, to create visible light. Tritium emits electrons through beta decay and, when they interact with a phosphor material, light is emitted through the process of phosphorescence. The overall process of using a radioactive material to excite a phosphor and ...
Neon tubes may partially burn out, and a conservator may identify the burned out portion of a neon artwork through use of a neon light tester, also known as a test light or voltage tester. This electronic test device is used to determine whether an electric current is running through the equipment being tested.
