A neon sign is a lighted tube of glass or plastic which emits light through an electrical current. As soon as you see a bright, glowing tube, it will remind you of where they are used best: within the walls of a store or business to market products. They can also be seen on highway signs that warn about upcoming traffic jams and speed limits. In recent years, more cities have started incorporating them into their streetlight designs for aesthetic purposes.
A neon sign could be considered an electronic billboard. They are about as long as a highway sign and as wide, as well. At the head of theirs is a glass or plastic tube that emits light through an intricate electrical circuit that activates with the same voltage as your household light switch. Their size is easily determined by the letters displayed on them. Neon signs are used most often in signage, in a number of industries from advertising to retail, and in public locations and buildings such as lobbies, restaurants, hotels and office buildings.
Here are some Facts Related to Yellow Neon sign:
1. The vast neon sign industry began in the early 1920s, when electric lights were introduced to major cities.
2. The color of neon signs is yellow because that color generally produces the brightest light and therefore, the least heat when it’s blown up in air (similar to how the filament of an incandescent light burner works). Neon also has a low electrical resistance and requires only AC voltage to activate it, which is considerably simpler than the DC voltages used in older incandescent lights and other electronic devices.
3. Of course, neon signs have no trouble with dimming, since, unlike other electric lights which burn out quickly or flicker the more you dim them, the brightness of a neon sign remains constant when you decrease its voltage (they are not constant-current devices).
4. It’s hard to overstate the importance of neon signs in the early 20th century. These electric lights were an important component of cityscape signage that had not existed before electrification (in fact, these bright light bulbs and signs have been credited for making nighttime cityscapes look so appealing that it increased urbanisation across the world).
5. Neon signs were also an important part of architecture, used in buildings to tell people where they were and what was around them.
6. Neon signs needed very little energy to operate yet produced a bright light that could be seen for miles at night (the glow of a neon sign was useful for streetlights). They also had no moving parts, so they were virtually indestructible (in fact, in the 1930s and 1940s neon signs were often mounted on vehicles to act as road-side beacons when vehicles lost their headlights during driving at night).
7. Neon lights can attract bees and wasps to them. They are also attracted to shiny surfaces and emit blue-green light, which is also attractive to bees and wasps.
8. Neon lights are one of the few forms of non-dimmable light sources, since they require a constant voltage, unlike “heater” bulbs which use a dimming ballast that can be turned on or off with an inexpensive switch (neon signs often run at higher voltages than traditional bulbs, up to 12 V).
9. yellow neon sign can also be made to glow in different colours. In fact, neon lights that glow blue-green have been used in the past to confuse bees, which see blue light as a signal of danger even when it is a harmless thing like the color of a neon sign light tube.
10. Neon lights can also be made to glow red or green (as long as the electric current is delivered at a voltage higher than about 6 V) for decorative purposes.
Due to their complexity and the fact that they need a constant power source, neon lights are not the cheapest or most durable lighting solution available. However, their bright light appears to be indispensable in many areas of advertising, design and architecture. Not only that but they are also very beautiful and unique to see especially in a positive way when they’re used as street lighting signs pointing toward the directions that there might be a sight to take.
