What Are Neon Signs?

So, what exactly are neon signs? If I tell you in simple words they’re actually the glass tubes filled with a special gas called neon. When electricity flows through these tubes this gas lights up and creates a signature glow that we all undeniably love. Neon signs have been around since the 1920s. And with its growing popularity it has become an iconic symbol of nightlife and creativity.

Do you want to know the science behind the neon signs? 

Let’s break it down a bit for you! At the core of every neon sign is neon gas. It's like a noble gas that doesn’t like to play with others. 

As you switch on a neon sign the sudden zipping of electricity through the gas excites those neon atoms. Which makes them illuminate a bright shining light. It’s like throwing a little party for the atoms!

And you know the fun fact? Neon lights typically illuminate a bright red-orange color. But you can get a rainbow of colors if you mix it up with other gases! 

For example, argon gas can give off a cool blue light. Similarly, the phosphor coatings can produce greens, yellows, and pinks. It’s this color variety that keeps neon signs so appealing!

Manufacturing Process

Are you wondering how these neon signs are actually made? 

Well, you might be very much surprised to know that making a neon sign is no les than art! Here’s how it typically goes down:

  1. Shaping the Glass: The manufacturing of teh neon signs starts as the skilled artisans heat glass tubes. They heat it until it gets quite soft enough to bend. They use specialized tools to create anything from it – ranging from simple shapes to intricate designs. It’s like crafting a piece of art!
  2. Filling the Tubes: After shaping the glass the artisans evacuate the air and fill the tubes with neon or other gases. This step is the most important as this is the one point that allows the gas to glow brightly when powered.
  3. Sealing the Tubes: As the tubes are filled with the gases the tube ends are then sealed. This step ensures that the gas stays inside, keeping your sign shining brightly for a longer time.
  4. Connecting to Power: The sealed tubes are then attached to a transformer which regulates the electricity flowing to the sign. This ensures that everything runs safely and smoothly.
  5. Testing: Finally, the sign is tested at the end. If it lights up without a hitch then Voila! It’s ready to shine!

Creating a neon sign not only takes skill but also demands patience. This is what makes each sign unique from the other.

LED Neon Signs: A Modern Alternative

The traditional gas-filled glass tubes are now getting older and out of trend. With LED neon signs, the trends are also getting a glow-up. These signs have gained popularity for good reason! They mimic the classic neon look but use flexible LED lights instead of gas-filled tubes. Saving you the hassle of neon gases.

Do you know what’s so great about LED neon? They’re the most energy-efficient, which is a big plus for both; your wallet and our planet. 

And the plus point is they’re safer to use as they don’t have any fragile or hazardous gases. That means there is no chance of breakage! They’re also super durable which makes them perfect for both indoor as well as outdoor usage.

So whether you love the traditional neon vibe or prefer the modern LED twist, there’s always something neon-ish for everyone!
