What is green neon sign?
Green neon sign, or “neon green” as it is sometimes called, is a fluorescent color commonly found in emergency exit signs and low voltage signs. This color can only be achieved by using a mixture of phosphors. Such as europium and green to generate the light.
Green neon sign was first invented at General Electric as a better alternative to mercury vapor lamps that were much worse for the environment. Green neon lights are also known for their ability to create very low temperatures.
What is the use of green neon sign?
Green neon sign uses fluorescent phosphor to help machines and electronic devices function correctly. Green neon can also be used in signs to indicate public warning. Such as those found on the side of road signals. The most common use of green neon is the lights used in roadway traffic signals and railway junctions. It is also useful for clear identification of signs with low-tension wires, for example, inside aircrafts, elevators and power plants.
Where can you find green neon?
Green neon can be seen all over the world. You will find green neon in greenhouses and old power stations as well as at places like airports, industrial plants, tube train stations, hospitals and even at your local shopping mall.
Where can you use it?
Green neon sign is very useful in places that require the extra visibility. This is because green neon is particularly bright and noticeable. Whenever you see a green light in a sign, you can be sure that it belongs to the category of green neon signs.
Why is it called green neon sign?
Green neon does not make use of mercury vapor but has its own special mix of phosphors combined with argon to make the light. A big advantage of this kind of green lighting compared to other forms of lighting like incandescent or fluorescent, is that its color will not change even after repeated exposure to UV light unlike the others which turn yellowish or brownish in due time.
What are its advantages?
The most common use of green neon is in traffic signals. These lights are very helpful in identifying the place where a traffic signal is placed at night. This color is also ideal for signs that need to be seen from afar. As well as signs that are used to warn people of danger.
What are the disadvantages?
Green neon does not use mercury so it can be recycled. But there are some limitations in using green neon. First, the brightness of the sign is quite low and the color may look faded after exposure to long hours of light from a fluorescent lamp. Second, the color of green neon is not as intense as other colors. Third, green neon does not have an indicator for full on or off. As most other signs do so it cannot be used for critical applications such as traffic signals, emergency lights or information basis signs.
Green neon sign is a great alternative to mercury vapor lamps. With its application in traffic signals and public signs, it has been effective in making places safer and more efficient. The biggest challenge faced by green neon is the fading of colors after exposure to UV light. Manufacturers are constantly working on improving the quality of this kind of green lights. So that they can be used more effectively even under difficult conditions. Such as those found in places like power plants and hospitals where there is a lot of industrial pollution.
