If temperatures drop LED Neon signs lose their brightness and look less appealing or are damaged. This is due to the effect that cold temperatures can have on gases. However, neon is an inert gas, so it cannot be blamed. Neon is also the most narrow liquid range, which is -248.45 degC up to -245.95 degC (-415.21 degF to -410.71 degF) this means that this gas can be resistant to cold temperatures.
Neon and gasses that are combined to create a variety of neon sign shades are those that are affected by temperature changes. Neon and Argon are the two most frequently used gases used to make neon signs. As stated, neon can stand up to cold temperatures. Argon will, however, react significantly in cold temperatures. This is why neon signs made of argon gas could dim, flicker, or even turn off as temperatures drop.
What’s going on?
The neon gasses used in signs typically work best at warm temperatures. The science of electricity has demonstrated that it produces heat. When a neon sign’s gas is contained within tubes, and later zapped by an electric source, it produces heat. The process is interrupted by cold temperatures, which can make neon signs dull or pinkish when it gets too cold.
Is there a way to solve this problem?
It doesn’t matter if your neon sign flickers or dims when it’s cold. It’ll still function in warm weather. There are a lot of neon signboards equipped with dark sign cabinets. These cabinets have fluorescent lamps which make the neon sign warmer during colder weather.
