The Alluring Science Behind Neon Signs

At the heart of every neon sign is a simple yet fascinating scientific principle. When an electric current passes through low-pressure neon gas, the gas atoms become excited and emit a bright glow. This isn't exclusive to neon; gases like argon, krypton, and xenon can also be used, each producing its distinct color. These gases are inert, meaning they don't readily react with other substances and are safely contained within the sign's sealed glass tubes.
At HDJ Sign, we've not only mastered the art of neon sign creation but also the intricate science behind it. Our custom neon signs are a blend of aesthetics and safety, ensuring that every piece is a masterpiece in its own right.

The Evolution of Neon Signs

The first neon signs, introduced in the early 20th century, were revolutionary, offering a brighter and more energy-efficient alternative to traditional incandescent bulbs. Over the decades, the technology has evolved, with modern neon signs being more durable, efficient, and environmentally friendly. Today, neon signs are not just about advertising; they've become a form of art, with artists and designers embracing the medium to create stunning visual displays.

Debunking Myths about Neon Signs

Myth 1: Neon Signs Emit Harmful Radiation
Neon signs do not emit harmful radiation. The glow is purely a result of electrical discharge, not radioactive decay. They're as safe as the LED lights that are prevalent in most homes and businesses today.

Myth 2: The Gases in Neon Signs are Dangerous
Neon, argon, and other gases used in neon signs are non-toxic and non-reactive. They pose no threat to the environment or humans.

Myth 3: Neon Signs are Fire Hazards
Like any electrical equipment, neon signs, if not installed or maintained properly, can pose risks. However, with regular maintenance and proper installation, they're as safe as any other electrical fixture.

Myth 4: Neon Signs Contain Mercury
While some older neon signs might contain mercury, modern signs, especially those crafted by HDJ Sign, use safer alternatives. We prioritize both environmental and safety concerns in our production process.
