The Magic of Neon Lights: How Electricity and Gas Create Glowing Tubes

custom neon signs have become the most sought-after option to decorate your bedroom. These neon signs are bright and beautiful and can immediately change the look of the space and give it a lively look. The neon signboards in offices are a great way to give offices a contemporary yet retro appearance.

A few neon light fixtures to your decor can give a fresh look to your design and make it appear brighter. It is possible to create fake neon signs by taking the help of many DIY tutorials. Have you ever wondered what natural neon lights appear like? How do they get so bright and vivid? How do they achieve these striking hues? Let’s get into it.

What is neon light?

The first question is what do you mean by neon lighting? Neon lighting is an electrified process that produces glass tubes or bulbs which emit a brilliant glow. Rarefied neon gas is contained in these glass tubes and bulbs. What exactly are rarefied gases? This means the gas is condensed to an amount lower than atmospheric pressure. This permits the gas to be contained in small tubes or bulbs. Neon lights are a type of cold cathode gas discharge light.

The end of each neon tube is filled with gas and is sealed with cathodes of metal. These cathode strips produce electricity which ions the gas contained within the tube. The electrons of these ions move on to the terminals of the lamp and thus complete the electric circuit. If the ions of neon have enough charge and gain enough energy to trigger by light, they release light.

It’s all about how particles move along different energy states. When an atom jumps from one energy level to another, it emits energy. The bulb is lit when neon atoms ionized inside it leap from one energy level to another. The color of the photon will depend on the gas inside it.

Let’s break it down to understand it a little bit more thoroughly.

The use of neon is due to this. What is the mechanism?

They are also referred to as neon lights. It is because the noble gas “neon” naturally gives off an orange light when it goes through this process. At the same time, other colors need to be produced using various chemicals and gases. This is why the name came to be. Let’s get to know the procedure a little better.

You might ask, what is the reason why neon, in particular, is intended for this use? Why is it not other gases, like nitrogen or oxygen? Neon is used because it is a noble gas. Noble gases have the distinctive property that each electron shell in an atom is filled. They are therefore not reactive in their state of nature. To get rid of an electron from the shell that is filled with electrons there is a lot of energy must be supplied to these electrons to stimulate them. Custom neon signs or neon lamps use either alternating current (AC) or direct current (DC) however, when used with a direct current, the light only is visible around one electrode. This is the reason that neon lights generally utilize alternating currents to emit light.

The tube inside which the gas is present is equipped with electrodes at both ends of the tube. These cathode terminals require electricity to function. A voltage of approximately 15,000 volts is needed to create the energy required to detach an outer electron from its electron shell. If the voltage supplied proves to be insufficient, the necessary kinetic energy to allow the electrons to escape from the cathode terminals won’t be sufficient for the process to able to take place.

Positively charged atoms move towards the negative terminal if there is enough kinetic energy. The free electrons (that is those that are negatively charged) are attracted toward the positive end. Positively or negatively charged particles make up the fourth state of matter, also known as plasma. They form the final part of the electric circuit.

What’s the most efficient way to produce light?

We have now figured out the entire mechanism of how the neon tube is charged and produces energy. The light comes from where? The tube’s electrons move when they’re exuberant by gaining energy and then hitting each other. They also exchange energy constantly.

They, therefore, have an increased energy level. However, this isn’t the normal configuration of the atoms. They attempt to release their energy to go back to their ground state. To do that they must release the energy stored in them. This is how neon tubes create light. The color, as we’ve previously discussed, is based on the chemical nature of the gas.

It is also dependent on the energy level at which the atom releases the energy. Atoms can be found at a variety of energy levels. The color of photon particles released will change by the energy level at which the atom is at. to return to its state of origin.

Simply put the electrons that are excited emit specific wavelengths of the photon. The color of each excited electron’s photon changes accordingly. Each noble gas has a distinctive color. For example, neon has a reddish-orange light, whereas Helium emits an orange glow.


A custom neon sign can be created with a variety of designs and colors. They are mostly used as wall art in bars and restaurants. Many offices are using custom neon signs to enhance their workplaces and make office environments high-spirited and exuberant.

Neon lights are a bit like fluorescent lights well. But, fluorescent lighting came into existence about 25 years before the neon lighting system and is usually used for getting an intense white light. In addition, neon lighting is used in plasma displays as well as glow lamps. In recent years the use of neon lights has become an increasingly popular art form in Europe as well as the USA.
