What is the history of neon lighting?
The vicinity of Times Square, New York City, has been famous for elaborate lighting displays incorporating neon signs since the 1920s. 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.
What are the functions and uses of neon lights?
Neon lights are bright and luminous, energized glass tubes or bulbs filled with rare neon gas or other rare gases. It is a cold cathode gas discharge lamp. This kind of lighting is very common in today's urban life, but many people are right. It may not know much, so what are the functions and uses of neon lights?
Why are neon signs made out of neon?
When an atom returns to a lower energy state, it releases a photon (light). You can make a fake neon sign yourself, but real neon lights consist of a glass tube filled with a small amount (low pressure) of neon gas. Neon is used because it is one of the noble gases.
Why do neon lamps glow?
Though these rare gases are invisible to the naked eye, each one glows with a distinctive brilliant color when sealed in a glass tube and energized with high voltage. These gas-discharge tubes, named for the electrical discharge that made them light up, would become the basis for neon lamps. Ramsay found neon’s light particularly striking.
What was the purpose of the neon lamp?
Visual indicator Small neon lamps are most widely used as visual indicators in electronic equipment and appliances, due to their low power consumption, long life, and ability to operate on mains power.
When was neon used for lights?
December 1910: Neon lights debut at Paris Motor Show. Paris is known as the “City of Light,” in part because it was the first to adopt gas street lighting. It also hosted the first neon lights, thanks to a French chemist and engineer who became known as the “Edison of Paris”: Georges Claude.
Who was the neon light invented for?
Georges ClaudeNeon lighting / InventorGeorges Claude was a French engineer and inventor. He is noted for his early work on the industrial liquefaction of air, for the invention and commercialization of neon lighting, and for a large experiment on generating energy by pumping cold seawater up from the depths. Wikipedia
What is the history of neon?
Neon was discovered (1898) by the British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. It was immediately recognized as a new element by its unique glow when electrically stimulated.
When did neon signs become popular?
1920sThey are the most common use for neon lighting, which was first demonstrated in a modern form in December 1910 by Georges Claude at the Paris Motor Show. While they are used worldwide, neon signs were popular in the United States from about the 1920s to 1950s.
When was neon colors invented?
Who Invented Neon? Neon colors made their first appearance in the form of lights in 1910. However, the process of creating “neon” started in the mid-1800s when Heinrich Geissler created sealed glass tubes with electrical currents, which caused the gases inside to glow vibrant colors.
What was the first neon color?
Inventor Georges Claude was the one to adapt Moore Lamps to use noble gases. In 1910, he successfully used neon gas to create the first neon lamp: a source of bright red-orange light that, by 1915, had taken America by storm.
When was neon created?

Who invented neon lights?
Neon lights were created by a French engineer named Georges Claude. He demonstrated his invention for the first time at the Paris Motor Show in 1910. Claude had previously created a method for liquifying air in 1902, and neon was a byproduct of the air liquifaction process he had developed. With the large quantities of neon gas he was producing at his air liquefaction business, he was able to create his neon lights.
Why did Claude use neon gas?
Because neon gas was the first type of gas that Claude used in his lights, the term “neon lights” was established. However, not all neon signs use neon gas. In fact, as his lights gained popularity, Claude began using different rarified gasses and fluorescent coatings with his tubes in order to create different colors. Some of the gasses he used included:
When did neon signs start?
The first product to advertise using a neon sign was Cizano in Paris in 1913. Then in 1919, the Paris Opera acquired their own neon sign. From there, the neon trend took off and Paris was aglow with neon lights. In 1923, neon lights were introduced to the United States. Claude’s company, Claude Neon, sold the first two neon signs in America to a Packard car dealership in Los Angeles. Soon after, neon signs exploded in popularity. Americans embraced neon lights in a way that no other country did. New York City’s Times Square was especially well known for using the new technology. Although neon lights were expensive, businesses considered them a novelty that caught consumer’s attention and helped them stay competitive. People would stop and stare at the glowing light, which was often referred to as “liquid fire.”
How many neon signs are there?
While neon lights eventually gave way to more efficient LED lighting, they still carry with them a certain fascination. Today, only about 18% of signs are neon lights, while 40% now use LEDs. However, neon lights are still visible in some storefronts and remain especially popular among businesses wishing to evoke nostalgia for the 1940s and 1950s in America.
What are neon lights used for?
Neon lights are colorful, bright, and reliable, so you see them used in signs, displays, and even airport landing strips. Have you ever wondered how they work and how different colors of light are produced?
How does neon light work?
A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited.
Why is neon used in chemistry?
Neon is used because it is one of the noble gases. One characteristic of these elements is that each atom has a filled electron shell, so the atoms don't react with other atoms and it takes a lot of energy to remove an electron . There is an electrode at either end of the tube.
What is a noble gas light?
If you see a clear light glowing in a color , it's a noble gas light.
What color is neon?
In other words, each excited noble gas releases a characteristic color of light. For neon, this is a reddish-orange light.
What gases are used to make colors?
One way is to use another gas or a mixture of gases to produce colors. As mentioned earlier, each noble gas releases a characteristic color of light. For example, helium glows pink, krypton is green, and argon is blue. If the gases are mixed, intermediate colors can be produced.
When was neon invented?
The neon light was demonstrated by Georges Claude in December of 1910 at the Paris Motor Show. Claude initially worked with Moore's design, but developed a reliable lamp design of his own and cornered the market for the lights until the 1930s. Cite this Article.
Who invented neon lighting?
After 1902, Georges Claude 's company, Air Liquide, was producing industrial quantities of neon as a byproduct of his air liquefaction business, and in December 1910 Claude demonstrated modern neon lighting based on a sealed tube of neon.
How do neon lamps work?
Neon lamps operate using a low current glow discharge. Higher power devices, such as mercury-vapor lamps or metal halide lamps use a higher current arc discharge. Low pressure sodium-vapor lamps use a neon Penning mixture for warm up and can be operated as giant neon lamps if operated in a low power mode.
How many lumens does a neon lamp produce?
Green neon lamps can produce up to 65 lumens per watt of power input, while white neon lamps have an efficacy of around 50 lumens per watt. In contrast, a standard incandescent lamps only produces around 13.5 lumens per watt.
What is a lamp made of?
The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode ). When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge. The glowing portion in the lamp is ...
What is a neon lamp?
Neon lamp. For similar terms, see Neon lighting and Neon sign. A neon lamp (also neon glow lamp) is a miniature gas discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode ). When sufficient voltage is applied ...
What color do Moore's lamps glow?
Moore mounted two electrodes close together in a bulb and added neon or argon gas. The electrodes would glow brightly in red or blue, depending on the gas, and the lamps lasted for years. Since the electrodes could take almost any shape imaginable, a popular application has been fanciful decorative lamps.
Why do neon lights flicker?
This may be a sign of aging of the indicator lamp, and is exploited in the decorative "flicker flame" neon lamps. However, while too low a current causes flickering, too high a current increases the wear of the electrodes by stimulating sputtering, which coats the internal surface of the lamp with metal and causes it to darken.
What was the use of neon in the 20th century?
During the 20th century, lights fueled by neon and its fellow noble gases were icons of commerce and entertainment, illuminating the modern age. Some early computers and calculators even used small neon tubes for circuits and displays.
Why do neon lamps glow?
Though these rare gases are invisible to the naked eye, each one glows with a distinctive brilliant color when sealed in a glass tube and energized with high voltage. These gas-discharge tubes, named for the electrical discharge that made them light up, would become the basis for neon lamps.
Why did neon tubes glow in the 1950s?
This unusual application was possible because of the way electricity functions in neon tubes. Electrons flow through a tube only when it is lit.
What was the neon sign that Anthony saw?
Anthony saw Claude’s neon signs on a visit to Paris and in 1923 commissioned a stylish promotion for his downtown showroom: two signs, each with “Packard” in elegant script, traced in orange neon tubing with a clear blue border (most likely produced by adding mercury to the neon).
What did Claude Neon do?
Making the most of his new invention, Claude formed another company, Claude Neon, to sell franchises for neon signage. Despite a high price tag—$100,000 plus royalties—dozens of franchises opened around the world, especially in major American cities. Neon was on its way to becoming a household name.
What is the story of neon?
A Blaze of Crimson Light: The Story of Neon. Neon is a dull and invisible gas until it’s trapped in a tube and zapped with electricity. Literally pulled out of thin air, neon became the bright light of the modern world, a symbol of progress, and an essential component of the electronic age. By Jane E. Boyd, Joseph Rucker | August 9, 2012.
Where were neon signs invented?
The first neon signs in the United States did not appear in New York or Las Vegas (which had a population of just a few thousand people in the early 1920s) but in the boomtown of Los Angeles. Entrepreneur Earle C. Anthony was a pioneer in several modern businesses, notably radio, automobiles, and gas stations. In 1915 he founded the first California dealership for the Packard Motor Car Company, a luxury brand, and remained the sole Packard distributor in the state through the 1950s. Anthony saw Claude’s neon signs on a visit to Paris and in 1923 commissioned a stylish promotion for his downtown showroom: two signs, each with “Packard” in elegant script, traced in orange neon tubing with a clear blue border (most likely produced by adding mercury to the neon). The signs cost $1,250—about half the price of a 1923 five-passenger Packard Single-Six Touring car—but Anthony’s investment paid off. The signs were a sensation, reportedly causing traffic jams as people stopped to marvel at their intense glow.

History and science
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 …
Neon tube lighting and signs
When Georges Claude demonstrated an impressive, practical form of neon tube lighting in 1910, he apparently envisioned that it would be used as a form of lighting, which had been the application of the earlier Moore tubes that were based on nitrogen and carbon dioxide discharges. Claude's 1910 demonstration of neon lighting at the Grand Palais (Grand Palace) in Paris lit a peristyle of this l…
Neon glow lamps and plasma displays
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. The energy dissipation in the lamps when they are glowing is very low (about 0.1 W), hence the distinguishin…
Neon lighting and artists in light
The mid to late 1980s was a period of resurgence in neon production. Sign companies developed a new type of signage called channel lettering, in which individual letters were fashioned from sheet metal.
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 indiv…
