The Effects of Cold Weather on Neon Sign Performance and Maintenance
When temperatures drop, neon signs can fade in brightness and appear unattractive or defective. This happens because cold temperatures affect the state of gases. However, neon is an inert gas so it is not to blame. Neon even has the narrowest liquid range, which is -248.45 degC to -245.95 degC (-415.21 degF to -410.71 degF) This implies that the gas will be resistant to cold temperatures.
The LED Neon signs that are affected by temperature changes will be formed when gases are mixed with neon. Neon and Argon are the two most frequently used gases to create neon signs. According to the literature, neon can stand up to cold temperatures. Argon can, however, react significantly in cold temperatures. As a result, neon signs made from Argon gas may dim or flicker, or stop working when the temperature drops.
What’s going on?
The gas used in neon signs typically works best when temperatures are warm. Research has proven that electricity can generate heat. If a LED Neon sign is enclosed in tubes, and later struck by an electric source, it emits heat. This process can be interrupted by cold temperatures that can make neon signs dim or pinkish if it is too cold.
Is there a solution?
Yes, it is!
There is no need to fret much about your neon sign dimming or flickering in cold weather conditions. It’ll still function in warm weather. Recently, you can find neon signboards equipped with dark sign cabinets. The cabinets are equipped with fluorescent lamps which warm the neon sign in cold temperatures.
