About this deal

While the market for neon lighting in outdoor advertising signage has declined since the mid twentieth century, in recent decades neon lighting has been used consciously in art, both in individual objects and integrated into architecture. Frank Popper traces the use of neon lighting as the principal element in artworks to Gyula Košice's late 1940s work in Argentina. Among the later artists whom Popper notes in a brief history of neon lighting in art are Stephen Antonakos, the conceptual artists Billy Apple, Joseph Kosuth, Bruce Nauman, Martial Raysse, Chryssa, Piotr Kowalski, Maurizio Nannucci and François Morellet [13] in addition to Lucio Fontana or Mario Merz.

San Jose, California is one of many cities that had an anti-neon ordinance; see Gaura, Maria Alicia (August 26, 1998). "San Jose Changes Neon Sign Ordinance / Way is cleared for Knight Ridder offices". San Francisco Chronicle . Retrieved 2010-11-27. Before yesterday's 8-to-2 vote to revise the ordinance, rooftop signs were not allowed on San Jose high-rise buildings, nor were colored neon signs. In addition, the maximum allowable size of signs on high-rise buildings was only 750 square feet. Neon was discovered in 1898 by the British scientists William Ramsay and Morris W. Travers. After obtaining pure neon from the atmosphere, they explored its properties using an "electrical gas-discharge" tube that was similar to the tubes used for neon signs today. Georges Claude, a French engineer and inventor, presented neon tube lighting in essentially its modern form at the Paris Motor Show, December 3–18, 1910. [4] [5] [6] Claude, sometimes called "the Edison of France", [7] had a near monopoly on the new technology, which became very popular for signage and displays in the period 1920–1940. Neon lighting was an important cultural phenomenon in the United States in that era; [8] by 1940, the downtowns of nearly every city in the US were bright with neon signage, and Times Square in New York City was known worldwide for its neon extravagances. [9] [10] There were 2,000 shops nationwide designing and fabricating neon signs. [11] [12] The popularity, intricacy, and scale of neon signage for advertising declined in the U.S. following the Second World War (1939–1945), but development continued vigorously in Japan, Iran, and some other countries. [11] In recent decades architects and artists, in addition to sign designers, have again adopted neon tube lighting as a component in their works. [11] [13] [14] 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.

O'Toole, Lawrence (February 4, 1990). "Where Neon Art Comes of Age". The New York Times. Americans, oddly, aren't so crazy about neon as the Japanese and the Europeans, although it could be argued that neon, discovered by the French inventor Georges Claude in 1910, is largely an American phenomenon. As explained in this article, Claude did not discover neon. 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] Tell, Darcy (2007).

We have your comfort at heart which is why all our blue neon signs are designed with a custom control panel so you can dim, brighten, and modify the glow of your blue neon sign to fit your mood or theme. Immediately following neon's discovery, neon tubes were used as scientific instruments and novelties. [16] However, the scarcity of purified neon gas precluded its prompt application for electrical gas-discharge lighting along the lines of Moore tubes, which used more common nitrogen or carbon dioxide as the working gas, and enjoyed some commercial success in the US in the early 1900s. [1] [17] After 1902, Georges Claude's company in France, Air Liquide, began producing industrial quantities of neon as a byproduct of the air liquefaction business. From December 3 to 18, 1910, Claude demonstrated two large (12-metre (39ft) long), bright red neon tubes at the Paris Motor Show.

Decorative (or "figural") lamps in which the cathode is shaped as a flower, animal, etc.. The figures inside these lamps were typically painted with phosphorescent paints to achieve a variety of colors. 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] a b c van Dulken, Stephen (2002).

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.

In neon glow lamps, the luminous region of the gas is a thin, "negative glow" region immediately adjacent to a negatively charged electrode (or "cathode"); the positively charged electrode ("anode") is quite close to the cathode. These features distinguish glow lamps from the much longer and brighter "positive column" luminous regions in neon tube lighting. [20] The energy dissipation in the lamps when they are glowing is very low (about 0.1 W), [31] hence the distinguishing term cold-cathode lighting.
