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.
Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals called phosphors are used to produce other colors, such as hydrogen (purple-red), helium (yellow or pink), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or ...
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."
“The collisions produce light much like how electrons flowing through gas in a neon light collide with neon and other gasses to produce different colored light bulbs,” the center explains.
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.
Neon's notable applications include its use in low-voltage neon glow lamps, high-voltage discharge tubes, and neon advertising signs, where it emits a distinct reddish-orange glow. [15] [16] This same red emission line is responsible for the characteristic red light of helium–neon lasers. Although neon has some applications in plasma tubes ...
Neon lamps are used both to produce light as indicators and for special-purpose illumination, and also as circuit elements displaying negative resistance. Addition of a trigger electrode to a device allowed the glow discharge to be initiated by an external control circuit; Bell Laboratories developed a "trigger tube" cold-cathode device in 1936 ...
