neon light tube

A type of cold cathode gas-discharge light is the neon light tube. Glass tubes with metal electrodes at each end make up the device.


Low pressure exists inside the tube's gases (such as neon, krypton or argon). These gases are ionized by a high potential of several thousand volts that is applied to the electrodes.


Origin

A red, orange, or pink glow is produced by a gas inside a neon lights tube when it is lit. This is the outcome of electricity flowing through it, which excites the gas's electrons. This amplifies their energy so that they can revert to their baseline state and emit photons of light.


When an electric current charges the electrodes at either end of the neon tube, a process known as "ionization" takes place. Free electrons are accelerated as a result, moving faster from the negative to the positive terminal. The neon gas inside the tube can then be ionized by these electrons, transferring energy and creating heat.


The atoms need to be electrically charged and under low pressure in order for this to happen. The same thing happens when a high voltage is applied to a battery. Heinrich Geissler, a German physicist and glassblower, discovered in 1856 that he could produce glowing light by passing an electric current through a variety of gases contained in tightly sealed glass tubes.


He also discovered that by using various gases and/or phosphor coatings on the inside of the glass tubes, these lights could be produced in a wide range of colors. By combining argon and mercury in a gas mixture, a wide range of colors can be produced in the most common way.


By applying ultraviolet-sensitive phosphors to the inside of the glass tubes, a variety of colors can also be created. The phosphors are excited and glow as a result of the ultraviolet light that is produced when mercury and phosphors are combined.


One of the so-called "noble" gasesu2014a group of elements distinguished by their resistance to forming bonds with other atomsu2014is neon. Four of these noble gases, including neon, were isolated by Scottish chemist Sir William Ramsay, who also received the Nobel Prize for this work.


Argon, krypton, and xenon were the other three noble gases. These gases are all rare natural substances that make up the atmosphere.


When illuminated by electricity, these gases can emit a variety of colors due to their capacity to ionize in a glass tube. They are so widely used as a form of lighting because of this. They can last for years or even decades without needing to be replaced and require very little maintenance.


  • Materials

    Materials

    A common gas discharge lamp used in commercial settings to produce a range of colors is the neon light strip tube. It is a reliable, enduring, and long-lasting lighting technology. It resembles other types of high-voltage light sources, like fluorescent lamps, in many ways. However, neon differs from other types of gas-filled tubing in that, unlike fluorescent tubes, it does not have a wire filament.


    A tiny quantity of the noble gas neon is contained in a glass tube in a neon tube. Due to its high electrical conductivity, this gas only experiences chemical changes when it comes into contact with an electrode inside the tube's current flow. Neon atoms inside the tube become excited when electricity passes through an electrode, releasing trapped electrons to form positively charged ions. The ions are then attracted to the positive electrode and repulsed away from the negative electrode, forming an electrical circuit that results in the production of light.


    Neon light manufacturing is a highly manual process that takes an expert craftsperson at least a year to master. To do this, the hollow tubing must be heated, bent, electrodes attached, and air removed. After welding electrodes to both ends of the sign tube, the completed tubing is filled with gas.


    The process of purification that follows the gas's placement in the tubing is sometimes referred to as "burning in the tube." This oxidation process eliminates impurities and enables the stabilization of neon gas. When the gas is finally ionized, it also aids in proper operation.


    The tube can be filled with mercury, an inert gas mixture, or argon to produce the desired color of light. Different ways in which the gases interact with one another result in a variety of hues.


    Phosphor coatings on some tube types are engineered to emit particular colors. For a neon light tube, it is not always necessary to coat these on the inside of the glass tubing.


    The majority of the signs are made from lead glass (crystal), which can be easily heated, bent, and shaped by hand. Other materials are also used to make the signs. There are several lengths available, including 4, 5, and 8 feet.

    A sturdy glass tube is made into a neon light by welding electrodes to each end of the tube, which is then filled with a mixture of noble gases. The kind of gas employed, how much gas is contained inside the glass tube, and how it interacts with a phosphor coating are just a few of the variables that affect the precise color of the glow emitted from the finished product.


    One of the most popular gases is led neon because, when electricity is applied to the electrodes at the ends of the glass tube, it emits a vivid red glow. However, when combined with electricity, other gases and chemicals can also generate a range of colors.


    Neon tubes are made of glass that has been internally coated with fluorescent powders and filled with a variety of gases to produce a wide range of colors. The energy from the noble gas is transformed into a variety of colors, including pink, turquoise, and green, by these phosphorescent powders.


    The glass tube can have a filter added to the outside or an interior fluorescent coating applied by technicians. This enables them to produce a wide range of different colored lights with different levels of intensity.


    A diode with three different color LEDs is one additional method for achieving a wider range of colors in a neon light. When the lights are turned on, these tiny diodes can be connected to an RGB controller and will produce a range of different colors.


    Red, yellow, and blue neon signs are the most popular colors, but technicians can create a variety of other colors by mixing various gases with fluorescent powders inside the glass tube. Additionally, a phosphor coating on the outside of the glass can be combined with these gases to produce a variety of other colors.


    These vibrant signs are a mainstay of contemporary art and culture and are well-liked for their powerful effects. They can be utilized for a variety of purposes, such as wall decorations and storefront displays.


    While neon has lost some of its appeal due to the use of LEDs, it is still a viable option for many people. The technology is straightforward and simple to comprehend, and it makes it possible to produce a wide range of different colors. Although the colors may not be as saturated or vibrant as those found in colored glass tubes, they can still be just as lovely and attention-grabbing.


  • Applications

    Applications

    A sealed glass tube filled with gasesu2014typically neon, but also argon and kryptonu2014is the basis of a neon light tube. Through electrical terminals at either end of the tube, a current is then passed, and the gas's atoms respond by glowing brightly colored as a result of the electricity.


    Red and orange colors can be seen in the neon lamp gas. The gas, the volume of gas inside the tube, and the strength of the current applied to the lamp all affect the color.


    When a high voltage is applied to the electrodes at either end of the gas-filled tube, neon atoms become ionized (that is, they lose their electrons). A photon of light is then produced when the ionized atoms recapture their electrons and transfer their energy to the positive electrodes.


    Similar to this, fluorescent lights use rarefied gases like mercury vapor that are ionized by electricity to emit ultraviolet light. Because the fluorescent lamp's gas is coated with phosphorescent materials that glow when exposed to ultraviolet rays from the rarefied mercury vapors, it will, however, produce a different color of light than a neon lamp.


    Different chemicals can be used to treat the phosphorescent material coating the inside of a fluorescent tube, changing the color and brightness of the light that is released. When a specific effect is desired, optical tints of various colors may be used, or the glass may be left clear if only a potent blue or green light is required.


    Adding other gases to the gas inside the glass tube of a neon light signs will also cause it to produce different colors. For instance, a manufacturer can combine helium and argon to create a powerful blue and purple glow. Alternately, they could paint the glass with a variety of phosphorescent materials that, when exposed to the rays produced by argon and helium, emit a range of red, green, and blue hues.


    Although there are many different kinds of neon signs available today, the first experiments with creating an electric lamp by running a current through a gas sealed in a glass tube were conducted by Heinrich Geissler in 1856. Although these initial experiments yielded some results, the electrodes' efficiency was very low, and the lamps soon started to sputter and eventually died. The fractional distillation of liquid air by William Ramsay and Morris Travers in 1898 was the next significant step. The neon light tube that is used today was created using this method.
