With so many options and designs available, buying a neon sign can be an exciting experience. However, it is vital to first understand how neon signs work and the important technical aspects of neon. This piece will provide functionality information and practical guidance about how the signs are created and how they work. We will also cover the benefits of using LED neon, as well as how the signs are commonly used.
In traditional neon signs, soft lead glass (crystal) is heated, bent and twisted by hand, then cooled and fused. They are later filled with various gases to achieve different colours. Pure-iron electrodes surrounded by a glass jacket are welded to both ends of the tube and wired to the transformer using high-voltage cables. The glass tubes are then mounted to a backing panel.
Faux neon signs (LED neon) signs have a different manufacturing process than traditional glass tubing neon signs. Rather than using glass or neon gas, LEDs are designed from made from acrylic—a thermoplastic better known as Altuglas or Perspex. Designing a LED neon sign consists of the following steps:
In traditional neon, there is an electrode at either end of the tube—one is negative, and one is positive. The gas inside a traditional neon tube is a noble gas, which means it only undergoes chemical reactions under high-energy conditions. When the gas comes into contact with electricity, it undergoes a chemical reaction. If you apply an alternating current to the electrodes, the electricity creates enough energy for the neon atoms to separate inside the tube.
Some electrons become positively charged ions, which fly towards the negative electrode. The free electrons have a negative charge and are drawn towards the positive electrode at the other end of the tube. As the neon atoms, ions and electrons bounce around the tube, they collide with each other, gradually increasing in energy. When the ionised atoms recapture their electrons to become neutral again, they release a particle of light known as a photon, which is what causes neon to give off a bright, coloured glow.
With LED neon, the reaction comes when electrons pass through a semiconductor, which is typically a material known as aluminium-gallium-arsenide. The LEDs must be positioned close to each other so they produce a steady source of light. This is similar to the effect of neon gas glowing inside a glass tube.
Custom neon signs allow you to choose from a wide variety of letter designs, colours and finishing touches. Having a custom neon sign designed also means you can choose the size of the sign, and some manufacturers can accommodate requests for whatever size you need. However, others can sometimes restrict you to certain standard sizes. There are very few limitations of what design you can have with LED neon.

You don’t need to be talented to art to present a design to a manufacturer. Many sign makers can work from a simple and quick concept. This could be something you’ve drawn, created online, or an image or photo you’ve taken. If you’re struggling to pinpoint a specific idea, you can take inspiration from a gallery of previous designs a manufacturer may have made.

You should also provide the following information to a sign manufacturer:
Most modern traditional neon signs come equipped with a 240v transformer and use about the same amount of electricity as a single domestic light bulb (60W–100W).
A typical LED neon sign will consume only 15%–20% of the power traditional neon uses on a similar job.
Neon signs are usually expected to last between 8 and 15 years. However, taking care of your neon sign means you can prolong its life span. Ensure you don’t leave your sign switched on for unnecessarily long periods, such as overnight with no supervision. This leaves it at risks of sustaining damage from electrical surges.
Due to how traditional neon signs work, energy generating from atoms, electrons and ions colliding with each other inside the tubes can sometimes occur as heat as well as light. The lower voltage of LED neon signs means they don’t get hot and will stay cool to the touch. The fact that LED neon signs don’t get hot means they use electricity more efficiently than traditional neon that wastes large amounts of power as heat rather than just light.
Signs in busy areas generally require more cleaning. Modern LED neon signs are wrapped in a protective polymer, whilst traditional neon signs use a neon glass tubing that is much more fragile. As LED neon signs are not hot to the touch when lit, they are much easier to clean. There are also no dangerous gasses within, unlike traditional neon signs. Although LED signs are much safer to touch, you should still switch off your sign and unplug it from the power source when cleaning.
To clean, you should first use a feather duster to lightly remove dust. For any remaining dust, you can use a nylon brush with soft bristles, using light pressure. If your sign has stains on, you can mix ½ cup of household ammonia with ½ cup of water in a plastic container. Dampen a cloth with the mixture to wring out any excess. Gently rub out any stains or grime from the surface of your signs.
Neon signs are an effective way to promote your business and reach out to your desired audience. Using a neon sign for your business enables customers to find you at any hour of the day or night, providing an invaluable branding asset. Using a neon sign to promote your business can help achieve the following:
You should consider the following factors when choosing where to place your neon sign:
