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 ...
Neon or argon are the most common gases used; krypton, xenon, and helium are used by artists for special purposes but are not used alone in normal signs. A premixed combination of argon and helium is often used in lieu of pure argon when a tube is to be installed in a cold climate, since the helium increases voltage drop (and thus power ...
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 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.
1841 Arc-lighting is used as experimental public lighting in Paris. 1853 Ignacy Łukasiewicz invents the modern kerosene lamp. 1856 glassblower Heinrich Geissler confines the electric arc in a Geissler tube. 1867 Edmond Becquerel demonstrates the first fluorescent lamp. [5] 1874 Alexander Lodygin patents an incandescent light bulb.
Sodium vapor lamps used in streetlights "Neon" signs, which use both visible light discharge from neon and other gases and phosphor excitation from ultraviolet light; Mercury vapor lamps; Mass spectrometers; Cathode-ray tubes, employed in the oscilloscope and later in television sets, radar, and computer display devices
Mixing metric and English units, there are also now G30 globes which are 30 mm (1 + 3 ⁄ 16 in, or G 9 + 1 ⁄ 2) in diameter using these sockets. These are still used for the classic look or even retro style, and use about five watts each. Older bulbs drew 7 + 1 ⁄ 2 watts of power, and were reduced to save power.
