How Neon Signs Work


The simplest explanation of how neon signs work is that a current passes through a glass tube containing an inert gas - typically argon or neon - and causes the gas to glow. The resulting stream of light is an alternating pattern of colours. Different sections of the sealed tubing are lit at various times with a simple timer to create the illusion of movement. The unlit tubes are illuminated and disappear into darkness while the lit ones appear bright with a characteristic glare. Read more on neon signs

The ionised atoms of neon return to a neutral state and emit a photon. This causes the resulting glow, so it is important to cut off the electricity supply to a neon sign if you want to use it outdoors. While it is possible for a fire to start from a burning neon sign, there is little risk of a neon sign igniting. However, it is important to know the safety and installation guidelines when using it in the workplace.

Large neon signs consist of multiple layers of glass tubing. The maximum length of each section is about eight to ten feet. Two electrodes are fused to each end of the glass tube, and a tubulation port is created to allow the tubes to be evacuated with a vacuum pump. Usually, a single electrode is enough for a sign. To make a small sign, multiple sections must be used. Depending on how many people work on the sign, the tube can be up to six stories high.

The finished glass pieces of a neon sign are illuminated by a transformer or switched-mode power supply. These supplies operate at voltages between two to fifteen kV and a current between eight and thirty mA. Higher currents can be ordered on special order. The chemical reaction between the gas inside the glass tube and the electric current causes light to be produced. The chemical reaction between the two gases causes a photon to be released, causing the neon to glow.

Although the production of neon signs is still primarily manual, it does not involve any sophisticated machinery. The process of producing a neon sign involves bending a glass tube and attaching electrodes to it. After attaching the electrodes, the tube is then filled with gas. After this, the tube is ready to be installed. If the sign requires electricity, it will need to be tested regularly. The neon signal must meet the IET Wiring Regulations in order to be compliant with British Standard BS 7671.

The manufacturing of a neon sign involves a series of steps. The first step is to create the sign. This involves designing the sign to fit the space. The other step is to design the lighting system. Then, it is important to note that the design of a neon sign is limited by its diameter and the number of atoms that are present in the tube. The light that emits from a neon sign is determined by the ionisation of the gas in the tube.

The process of making a neon sign involves several steps. It must be connected to a transformer which steps the voltage between 120 and 15000 volts. The transformers connect the neon lights to the insulating housing with GTO wire. The wire is then connected to the transformer with a spring connection. The electrical connections must be tested for safety before a neon sign can be used. If a flame is present, the sign must be disconnected immediately.

In 1923, the first neon signs were made in the United States. Claude's two signs were used in the Los Angeles car dealership Earle C. Anthony. During the 1920s, neon tubes began to be used in decorative displays and signage. By 1947, several Las Vegas casinos began to attract attention with their neon displays. In fact, they now host monthly tours of famous neon display locations in the area. The history of a neon sign is fascinating.

In the 1870s, a French astronomer named Jean Picard observed a faint glow coming from a mercury barometer. He assumed that the glowing tube was caused by barometric light. He then experimented with the effect, and eventually developed a lighted tube. It was only a matter of time before LEDs started replacing the old neon signs. The first neon signs were created in 1873 and were installed around the world.
