How Neon Lights Are Made — The Production of Neon Lights

Have you ever wondered how neon lights are made? Here’s a brief explanation. Neon lights are composed of a glass tube that contains an inert gas. During the manufacturing process, the glass tube is carefully shaped to fit the light. This process is known as tube bending, and it can be tricky because the glass tube can be stressed. If the glass tube is stressed, it might break and leak gas when the light is turned on. The next step is annealing, which is a process that cools the glass tube. It also helps the gas settle evenly in the glass tube.

Glass Tube FIlled with Inert Gas

A neon light emits light when an electrical current passes through it. The inert gas, neon, is the most common and cheapest. The gas also produces a deep red glow when lit, but can also be a soothing blue. Most neon signs contain mercury vapor, which is more expensive than pure neon, and argon combines with helium to produce a more intense blue. To produce the colors of neon signs, manufacturers will paint the inside of the glass tube with ultraviolet-sensitive phosphors. When the tubes are electrified, the phosphors glow, causing the lights to appear in a variety of colors.

Although most neon lights contain neon, they may not be coated with this substance. Some are, though, and phosphor coatings will produce some of the most vivid colors. Phosphor powder is also added to the glass tube, which makes it possible to make neon lights in a variety of colors. If the phosphor powder is applied correctly, the neon light will be visible in a variety of colors.

The manufacturing process for a neon light is remarkably simple. A glass tube is filled with inert gas, and a glass electrode is attached to one end. The outside end of the glass tube is connected to the power source, and when the power source is switched on, a current passes through the electrode and into the molecules of the noble gas inside the neon glass tube. The glass tube is then blown to the right thickness and the molten gas is pumped inside it.

The process of producing neon signs, like the ones that you will see on the Neon Mama site, began with scientific experiments. In 1856, Heinrich Geissler produced a light source by passing high-voltage alternating current through a glass tube filled with a low-pressure gas. Further experiments revealed that many gases conduct electric currents. However, the common gases react with the electrodes and reduce the efficiency of the system. Eventually, Sir William Ramsay discovered how to fractionally distill liquid air.

AC or DC Current

The neon light is made up of a tube filled with atoms and a source of electricity. The electricity is used to excite the electrons, creating a ray of light when the device is turned on. Neon lights are beautiful, catchy, and reliable. They are used in advertising, in museums, and in science experiments. AC or DC current is used to create them. However, many modern neon lights do not use AC or DC current.

The most common use of neon lights is as a storefront sign. They are reliable, colorful, and easy to see. While neon naturally emits a red glow, its ability to change colors is unmatched by any other type of light. This makes them the perfect choice for the advertising industry. The bright and vivid colors of neon lights catch the attention of passersby. They are also very durable and can withstand extreme temperatures.

AC neon lights use alternating current, while DC ones use direct current. To use both, separate wires must be run through the sign’s backside and pulled toward the neon tubes. The caps must be removed. Once the wiring is complete, place the neon tubes back onto the sign. Ensure the power wires are underneath. This will prevent them from breaking off. If you are unsure about which type of current your sign requires, refer to the installation manual to find out how to properly make neon lights.

Neon lights can also be made with other colors of light. A mixture of certain gases can produce various shades of light, including white, red, and blue. These gases can also be used to create intermediate hues. They can be used to make custom neon lights for a specific place or event. A business can order neon lights in bulk, or request custom lighting for their business. The cost of neon lights may depend on the number of people who use them.

Tube Benders

Tube benders are the last craftspeople who can still make neon signs, and this process is becoming increasingly rare. As neon becomes more expensive, the demand for handmade signs is dwindling. LED lights have stepped in to take their place, but their look is far from as authentic as a handcrafted neon sign. The last true tube bender in Northern Nevada is Ken Hines, who has been making neon signs for nearly forty years. Although only a handful of glass benders in the region still work, he is the last full-time neon tube bender in the region.

The process begins with a section of glass that is heated until it becomes malleable. The next step involves joining the two pieces together to make a sign. In some cases, multiple sections of the glass must be joined to form a single sign. This can be done with the use of a hand-held flame tool. The glass tube bender then welds electrodes onto the ends of each tube. The finished sign is then removed from the manifold and “bombarded” with high voltage.

While some tubes are filled with neon, some are not. Depending on the manufacturer, some tubes are filled with gas that is not compatible with neon. In this case, a manufacturer will use argon gas to make clear tubes, while xenon is used in coated tubes. The combination of glass will create countless color combinations. Choosing the right gas for your project is vital, and a neon designer can help you make the right decision for your requirements. They will consider aesthetics and local tubing availability when making manufacturing decisions.

While a career as a tube bender may sound glamorous and attractive, it’s a tough industry to break into, and you’ll need to have passion and desire to learn the trade. Without a strong desire to learn, the chances of success are slim. In the long run, however, a new generation of tube benders could take the torch, and the art of neon will be reborn.

Colors of Neon Tubes

The underlying mechanism of colors produced by neon tubes is remarkably simple. As a result of the heat generated in the atoms of the tube, they are in motion, hitting each other and transferring energy. In turn, this process produces heat, and some electrons escape and gain energy. These extra electrons can now be found on a higher rung on the energy ladder. The distance between them and the original energy of the atom determines what color the light will be.

To create the red neon color, manufacturers first fill a strong glass tube with neon gas. Then, they add a different noble gas or fill the tube with other colored gases. The gas is what makes the neon glow, and the more you add, the more vivid the color will be. Common gases used in neon signs are mercury, argon, and helium. Listed below are the common gases found in neon signs.

The color of neon is determined by the type of gas used to encase the glass tube. The gas will react with electricity to emit visible light. The gas in the tubes also produces infrared light, which can be converted into visible energy. The most common color produced by neon gas is pink. The gas also emits fluorescence, which gives off light in a variety of colors. For this reason, neon signs are often categorized according to the color they emit.

While there are a variety of different gases used in making neon signs, the basic formula remains the same: glass tubes filled with gases are the key. Neon can be made of either straight gas or a mix of hydrogen, helium, or colored glass tubes. The tubes are then sealed. When the gas passes through the tube, it reacts with the surrounding gas, causing the color to glow. However, unlike fluorescent tubes, neon cannot produce green or blue light. This is why the color of neon lights depends on the atoms that are within the glass tube.

Techniques Used to Make Them

Neon lights are made by putting electrodes at the end of the glass tube. The electrode tip is connected to a power supply, and when the electricity is on, the current flows through the electrode to the molecules of noble gas inside the tube. The glass tube is cleaned and then air is evacuated to create a vacuum. Dry air is then introduced to the glass to build pressure. The electrodes are then placed and the glass tube is cooled.

Neon lights are made using two gases – argon and hydrogen – which glow red or orange when energized. Both gases are noble gases, meaning that they are non-reactive, and the removal of their electrons requires a tremendous amount of energy. Unlike ordinary lights, neon lights use either direct current or alternating current, and the glow is only visible around one electrode. Listed below are techniques used to make neon lights.

Most large neon signs use several sections of glass tubing. Generally, eight to ten feet is the maximum practical length of a neon sign. The two sections are then heated together and electrodes are fused to one end of each. There is an opening in the tubing called a tubulation port. These electrodes are insulated, and a small glass shell surrounds them. A wire is attached to the electrodes.

The mid-to-late 1980s were another period in neon production. Sign companies began producing different types of signage using the same techniques. This new type of signage was called channel lettering, and it was a great success. Neon is used in advertising to promote a business or brand. One of the most common examples of neon signs in today’s cities is the iconic Super Bowl in New York.
