Neon Signs

Neon signs and Neon Lights are made using a process that involves bending glass tubes into various shapes and filling them with gases to produce the characteristic glowing effect. The most common noble gas that is used is neon hence the name, ‘neon signs’. A neon light consists of a sealed glass tube that has electrodes and is filled with a noble gas. The general principle of how a neon sign works is electric current flows from the power supply to the electrodes in the glass tube. The molecules of the gas in the tube get activated as electric current flows and emit light. Neon light is emitted from the ‘sparks’ of these molecules vibrating against each other.

How Neon Lights and Neon Signs are made:

Design: The process starts with designing the sign, including the layout of the letters, shapes, or images that will form how the neon fits into the overall sign design. 

Glass Tubing: The next step involves creating the glass tubing that will make up the sign. Glass is a fragile material. Typically, the glass used is clear or coloured, and it comes in straight lengths. Neon lights are made using soft lead glass tubes in 1200mm lengths.  The glass is heated and bent into the desired shapes by skilled artisans using a process called glass blowing or glass tube bending. The glass processing proceeds as follows: 

Cleaning: The glass tubes are cleaned to ensure neon light maximum clarity. What makes neon signs glow so brightly is the phosphor coating. Some neon light manufacturers may tint the glass tubing with colour. Not all neon lighting glass tubes are coated in phosphor or colour. It is a technique mostly used to bring about a glowing effect or produce interesting colours of neon light. This is made possible by the fact that phosphor coatings are available in different colours.

Electrodes: Electrodes are attached to each end of the glass tubing. An electrode is a conductor that is used to create a circuit through the noble gas in a neon glass tube. These electrodes are usually made of metals like iron which is a good conductor of electricity. The core of the electrode is encased in glass but each electrode has 2 conductor wires that extend outside the glass casing. The tip of the electrode facing outside the glass tube is connected to the power supply source. When the power source is turned on, a current flows through the electrode and into the molecules of the noble gas inside the neon glass tube. Electrodes are attached on the bent shaped glass before the glass tube is filled with gas.

Evacuation the glass tubes:  The air inside the glass has to first be evacuated to remove impurities out of the glass tube in order to be filled with pure noble gas, Otherwise, it would ‘dilute’ and yield poor neon lighting. The process used to evacuate the air from the glass tubing is referred to as ‘bombarding’. It occurs as follows: The air in the glass tube is evacuated until the inside of the glass is a vacuum. Dry air is introduced into the glass to build pressure. Depending on the length of the tubing, an electric current of about 400-750 milliamperes is run through the electrodes and into the glass. It heats the tubing to over 204 degrees celsius. The electrode in the glass tube is equally heated to over 371 degrees celsius. The tube is once again evacuated into a vacuum below 10 torrs. Noble gases have the same overall characteristics but they are not identical, because of this reason, each of them is filled with a unique pressure. The amount of pressure used also depends on the diameter of the glass tube; the larger the diameter, the more the pressure required. Different noble gases are used to produce different colours of neon lighting. Neon produces red-orange hues. Argon is used to make light blue neon signs. 

Filing the gas: The gas-filled neon light glass tube is slowly heated and then allowed to cool on its own. This process is known as annealing. Annealing is equally vital in ensuring that the gas properly settles into the glass tubing. As the tube is heated, it expands and the gas has a chance to spread evenly. As a result, the lighting in the glass tube will likely be consistent throughout the entire length of the tubing. When the gas is filled into the glass tube, and the level of pressure is right, the tube is sealed by heating the tubular port on the electrode until it shuts. Over 100 colours of neon lights can be realised by combining different noble gases and different glass tube coatings.

Sealing: Once the tubes are filled with gas, the ends are sealed. The sealing process ensures that the gas remains inside the tube.

Testing: With all components in place and the glass tubing ‘de-stressed’ and cooled, the neon light would be ready for testing. The power source is turned on to deliver electric current and soon the neon light should begin to glow. The completed tubes are tested to ensure they are airtight and that the gas inside is at the correct pressure. This is crucial for the proper functioning of the sign.

Mounting and Wiring: The tubes are mounted onto a backing board or frame according to the design, and the wiring is connected to the electrodes. The wiring is designed to provide the electrical current necessary to ionise the gas inside the tubes.

Final Assembly: The final assembly involves putting all the components together, securing the electrical connections, and making any final adjustments to the placement of the tubes.

Installation: Once the neon sign is fully assembled and tested, it can be installed at its intended location. Neon signs are often mounted on walls, storefronts, or other prominent locations.

Neon signs have been popular for decades due to their vibrant colours and distinctive appearance emitting a unique coloured lighting that glows which is near impossible to achieve with other forms of lighting. While LED technology has become more prevalent in recent years, neon signs continue to be appreciated for their unique aesthetic.
