Archived from the original on 2010-06-20.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 high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals 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 pictures. They are mainly used to make dramatic, multicolored glowing signage for advertising, called neon signs, which were popular from the 1920s to 1960s and again in the 1980s.

Weeks, Mary Elvira (2003). Discovery of the Elements: Third Edition (reprint). Kessinger Publishing. p.287. ISBN 978-0-7661-3872-8. [ permanent dead link] Neon is a noble gas chemical element and an inert gas that is a minor component of the Earth's atmosphere. It was discovered in 1898 by the British scientists William Ramsay and Morris W. Travers. When Ramsay and Travers had succeeded in obtaining pure neon from the atmosphere, they explored its properties using an "electrical gas-discharge" tube that was similar to the tubes used today for neon signs. 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." [15] The procedure of examining the colors of the light emitted from gas-discharge (or "Geissler" tubes) was well known at the time, since the colors of light (the "spectral lines") emitted by a gas discharge tube are, essentially, fingerprints that identify the gases inside. The term can also refer to the miniature neon glow lamp, developed in 1917, about seven years after neon tube lighting. [1] While neon tube lights are typically meters long, the neon lamps can be less than one centimeter in length and glow much more dimly than the tube lights. They are still in use as small indicator lights. Through the 1970s, neon glow lamps were widely used for numerical displays in electronics, for small decorative lamps, and as signal processing devices in circuitry. While these lamps are now antiques, the technology of the neon glow lamp developed into contemporary plasma displays and televisions. [2] [3]The small size of the negative glow region of a neon lamp, and the flexible electronic properties that were exploited in electronic circuits, led to the adoption of this technology for the earliest plasma panel displays. The first monochrome dot-matrix plasma panel displays were developed in 1964 at the University of Illinois for the PLATO educational computing system. They had the characteristic color of the neon lamp; their inventors, Donald L. Bitzer, H. Gene Slottow, and Robert H. Wilson, had achieved a working computer display that remembered its own state, and did not require constant refreshing from the central computer system. The relationship between these early monochrome displays and contemporary, color plasma displays and televisions was described by Larry F. Weber in 2006, "All plasma TVs on the market today have the same features that were demonstrated in the first plasma display which was a device with only a single cell. These features include alternating sustain voltage, dielectric layer, wall charge, and a neon-based gas mixture." [3] As in colored neon lamps, plasma displays use a gas mixture that emits ultraviolet light. Each pixel has a phosphor that emits one of the display's base colors.

These neon tubes were essentially in their contemporary form. [11] [19] [20] The outer diameters for the glass tubing used in neon lighting ranges from 9 to 25mm; with standard electrical equipment, the tubes can be as long as 30 metres (98ft). [21] The pressure of the gas inside ranges from 3 to 20 Torr (0.4–3 kPa), which corresponds to a partial vacuum in the tubing. Claude had also solved two technical problems that substantially shortened the working life of neon and some other gas discharge tubes, [22] and effectively gave birth to a neon lighting industry. In 1915, a US patent was issued to Claude covering the design of the electrodes for gas-discharge lighting; [23] this patent became the basis for the monopoly held in the US by his company, Claude Neon Lights, for neon signs through the early 1930s. [24] Neon lighting is closely related to fluorescent lighting, which developed about 25 years after neon tube lighting. [12] In fluorescent lights, the light emitted by rarefied gases within a tube is used exclusively to excite fluorescent materials that coat the tube, which then shine with their own colors that become the tube's visible, usually white, glow. Fluorescent coatings and glasses are also an option for neon tube lighting, but are usually selected to obtain bright colors. Claude's patents envisioned the use of gases such as argon and mercury vapor to create different colors beyond those produced by neon. For instance, mixing metallic mercury with neon gas creates blue. Green can then be achieved using uranium (yellow) glass. White and gold can also be created by adding argon and helium. [25] In the 1920s, fluorescent glasses and coatings were developed to further expand the range of colors and effects for tubes with argon gas or argon-neon mixtures; generally, the fluorescent coatings are used with an argon/mercury-vapor mixture, which emits ultraviolet light that activates the fluorescent coatings. [12] By the 1930s, the colors from combinations of neon tube lights had become satisfactory for some general interior lighting applications, and achieved some success in Europe, but not in the US. [12] Since the 1950s, the development of phosphors for color televisions has created nearly 100 new colors for neon tube lighting. [14]a b c d e f g h i Stern, Rudi (1988). The New Let There Be Neon.

Fleming used a tube of neon, without electrodes, to explore the amplitudes of radiofrequency waves by examining the intensity of the tube's light emission. He had obtained his neon directly from its discoverer, Ramsay.
