If temperatures drop neon signs may fade in brightness and appear less appealing or be damaged. This is because of the effects that cold temperatures can have on gases. However neon is an inert gas, so it can’t be blamed. Neon is in the most liquid range, -248.45 to -245.95 degrees Celsius (-415.21 to -410.71 degrees Fahrenheit), which means it is not affected by cold temperatures.
Neon and gasses that are combined to create a variety of neon sign colors are the ones that are affected by temperature changes. Neon and Argon are the two most commonly used gasses to create neon signs. And as stated above neon can withstand frigid temperatures. Argon can, however, react strongly to cold temperatures. This is why neon signs made of argon gas could dim, flicker, or even turn off as temperatures drop.
LED Neon signs make use of neon gases that work best in warmer temperatures. Additionally, science has demonstrated that electricity creates heat. If a LED Neon sign‘s gas is contained in a tube and struck by an electric source, it emits heat. The cold temperatures can hinder the process and if it is cold enough the tubes used in neon signs dim or pinkish.
Is there a way to solve this problem?
Yes, it is!
You don’t need to worry much about your neon’s dimming or flickering during cold weather conditions. It will work perfectly when it gets warm. There are a lot of neon signboards that have dim sign cabinets. These cabinets have fluorescent lamps that heat the neon sign in cold weather.
