1. All about gases used in neon signs

In the question "what gas is used in neon signs", Orant Neon will go over the many use cases for each type of gas in the information below.

1.1 What is neon gas?

Air purification is easy and cheap because neon makes up just a small portion of the air you breathe. Since it emits a bright red glow, it is the most popular gas used for signage. A neon sign may be created with very little gas. Although the sign fixtures require high voltages, they are energy-efficient since their milliwatt-level power consumption is so low.

The red light will come from neon gas

1.2 Is neon gas rare?

Neon is a chemical element that belongs to group 18 of the periodic table and is a noble gas. Helium, argon, krypton, xenon, and radon are the other naturally occurring members of this group. The first synthetic noble gas was created in 2002, making a total of seven neon gases in existence today. The inertness of noble gases, or their extremely low chemical reactivity, is well recognized.

Other gases in the group include helium, argon, krypton, xenon

1.3 What colour is neon gas?

Neon gas is colorless under normal circumstances, but when electricity is added, it emits a vivid red-orange light or discharge. Each noble gas has a distinct discharge color. Here are the gases used in neon signs and their colors:

  • Helium: is orange-yellow
  • Argon: is lavender/light purple or light blue
  • Krypton: is white-blueish
  • Xenon: is blue
  • Radon: is red

2. What gases are used in neon lights?

Mercury, argon, and helium are the three most popular gases used to create neon signs that are brilliant and colorful. If you're wondering "what gas is used in neon lights", read the information below.

 Gases found in neon signs Purpose of use
Neon Gas - Most commonly used gas in neon signs.
- Produces a bright red-orange glow.
- Emits a characteristic red light when an electric current passes through it.
Argon Gas - Often used in combination with other gases in neon signs.
- Produces a blue light when subjected to electricity.
Helium Gas - Occasionally used in neon signs.
- Produces a lighter, pinkish color.
- Emits a pinkish-red light when electrified.
Krypton Gas
- Used in neon signs for colors like white, gray, or light purple.
- Emits a whitish or pale purple light when excited by electricity.
Xenon Gas - Less commonly used in neon signs.
- Produces colors such as blue, purple, and lavender.
- Emits a bluish light when ionized.

2.1 Mercury Vapor

The vapor of mercury emits a calming and delicate blue hue. If you pay attention to street lights when they first turn on, you could see the blue hue caused by mercury vapor (because the majority of these lamps' chemical composition includes mercury).

Depending on whether the producer wishes to produce colors with a cold or warm base hue, the majority of neon signs either include neon or mercury vapor. A manufacturer is more likely to employ mercury than neon when aiming for cool hues like green or purple.

Because mercury is present, Mercury Vapor's gas will be green

2.2 Argon

To create a deeper, more vivid shade of blue, artisans frequently combine argon and mercury. In order to achieve various hues, the manufacturer may occasionally paint the interior of the glass tubing with UV-sensitive phosphors. The UV light produced by the mercury in the mixture causes the phosphors to shine.

A neon sign's clear, effervescent blue, green, yellow, or white hue indicates that argon gas is probably present in the neon tube.

Argon and mercury must be combined to produce vibrant colors

2.3 Helium

Manufacturers can add helium to the mercury and argon combination to speed up the light heating in colder climates. Helium emits a pinkish-red light when used alone. Pure helium is one of the most difficult gases on this list to find. The majority of helium used in industry is produced by radioactive decay or originates from a natural gas deposit.

When used alone, helium produces a pinkish-red glow

2.4 Xenon

The illumination from xenon is very violet. Although they also include it in the mixture within a neon light, artisans mostly utilize xenon in strobe lights and photography. Xenon emits a variety of colors when mixed with other noble gases.

In combination with other noble gases, xenon emits a range of colors

2.5 Krypton

Low-level, whitish-yellow light emanates from Krypton. Krypton is used by manufacturers to create a wide range of colors because of its property. Craftsmen often rely on tinted glass to provide the perceived color when adding krypton to lighting tubes. Manufacturers also employ krypton gas for safety lighting, such as the runway lights at airports, in addition to neon signs.
