1.ネオンサインの仕組み

ネオンサイン are made of glass tubes filled with ネオンガス or other gases. When an electric current is passed through the ガラス管, the ガス inside becomes excited and emits light. This process, known as electroluminescence, is what gives ネオンサイン their distinctive glow. The color of the light depends on the type of ガス used; pure ネオンガス produces a reddish-orange light, while other gases like argon or helium create different colors. Neon signs require specific care, and a neon sign may need repairs.

Each end of the ガラス管 is fitted with an electrode, which connects to a 変流器.その 変流器 steps up the voltage of the electrical supply, providing the high voltage needed to ionize the ガス and make it light up. ネオンサイン are known for their vibrant colors and have been a popular form of signage for decades. Understanding how they work can help you appreciate the complexity and artistry involved in their creation and maintenance.

2. Can Neon Signs Be Repaired?

4. Troubleshooting Flickering Neon Lights

Flickering neon lights are a common issue that can often be resolved with some troubleshooting. Flickering neon can be caused by several factors, including a failing 変流器, a damaged ネオン管, or loose electrical connections. Since ネオンサイン are sensitive, even small issues can cause problems. Begin by checking the power supply to ensure the ネオンサイン is properly plugged in and receiving power. If the power supply is fine, inspect the 変流器. A buzzing or humming sound from the 変流器 can indicate that it’s failing and needs to be replaced.

If the 変流器 seems to be in good working order, examine the ガラス管 for any signs of damage, such as cracks or dark spots. A damaged ネオン管 may need to be replaced by a professional. Additionally, check the wiring and connections for any loose or shorted or broken wires. Tightening loose connections or repairing damaged wiring can sometimes resolve flickering neon lights. If you’re not comfortable working with electrical components, it’s best to consult a professional neon sign repair service. If the neon gas starts to light up, but then the ネオンサイン turns off, it is likely a flickering neon sign.

5. How to Fix a Broken Neon Sign

Fixing a broken neon sign involves identifying the damaged component and either repairing or replacing it. Common issues include broken neon glass, a failing 変流器, or faulty wiring. If you have a sign with a broken glass tube, the broken neon glass will need to be replaced by a professional neon sign maker. They can create a new neon tube that matches the original design and refill it with the appropriate ガス. Repair ブロークンネオン tubes by replacing the leaking tube with a new one.

If the 変流器 is the problem, you’ll need to replace it with a new one that matches the voltage and current requirements of your ネオンサイン. When dealing with a 壊れたネオンサイン, carefully inspect the wiring for any loose or damaged connections. Repairing or replacing broken or damaged cables can often restore the ネオンサイン to working order. Always ensure the サイン is unplugged before attempting any repairs, and if you’re not experienced with electrical work, seek assistance from a professional to avoid safety hazards. Fix a neon sign by identifying the issue.
