What Are Neon Signs?
Neon signs are electric gas-discharge lamps that emit light when an electric current passes through the gas contained within glass tubes. These tubes are shaped into various letters, symbols, or designs, making neon signs popular for advertising and decoration.
The Role of Gases in Neon Signs
Neon Gas
Neon gas is the most recognized gas used in neon signage. When electricity is applied, neon emits a vibrant orange-red glow. This distinct color is often associated with neon signs and is one of the primary reasons they are popular for nighttime advertising.
Argon Gas
Argon gas is another noble gas commonly used in neon signs. When ionized, argon produces a blue light. It is often favored for creating a cooler tone in signage and can be paired with phosphor coatings to produce a wider array of colors.
Other Noble Gases
In addition to neon and argon, other noble gases such as krypton and xenon are also utilized in some neon signs. Krypton can produce a bright white light, while xenon creates a range of colors depending on the phosphor coatings applied.
Colors Produced by Different Gases
Neon: The Classic Orange
The classic color of neon is an orange-red glow, which is produced when neon gas is ionized. This color is highly recognizable and often associated with vintage signage.
Argon: Blue Glow
When argon gas is ionized, it emits a soft blue light. This color is less common than neon orange but is increasingly being used in modern signage, often in combinations with other colors.
Combining Gases for Variety
Many neon signs achieve unique colors by combining gases and using phosphor coatings. For example:
- Red: Neon gas with a red phosphor.
- Green: Argon gas with a green phosphor.
- Pink: A mixture of neon gas and phosphor that creates pink hues.
Creating Custom Colors
Customized neon signs can be created by mixing different gases and applying various phosphor coatings to achieve specific colors. This versatility allows artists and businesses to design eye-catching signs that stand out in various environments.
Conclusion
The world of neon signs is fascinating, with gases like neon and argon playing a crucial role in producing the vibrant colors that catch our attention. By understanding the gases used in neon signs and their colors, we can appreciate the artistry and science behind these glowing displays.
If you’re considering a neon sign for your business or personal space, think about the impact of color and gas choices to ensure your sign stands out brilliantly.
