Neon lighting is closely related to fluorescent lighting, which developed about 25 years after neon tube lighting. [12] In fluorescent lights, the light emitted by rarefied gases within a tube is used exclusively to excite fluorescent materials that coat the tube, which then shine with their own colors that become the tube's visible, usually ...
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
The next major technological innovation in neon lighting and signs was the development of fluorescent tube coatings. [22] Jacques Risler received a French patent in 1926 for these. [5] Neon signs that use an argon/mercury gas mixture emit a good deal of ultraviolet light. When this light is absorbed by a fluorescent coating, preferably inside ...
Neon's notable applications include its use in low-voltage neon glow lamps, high-voltage discharge tubes, and neon advertising signs, where it emits a distinct reddish-orange glow. [15] [16] This same red emission line is responsible for the characteristic red light of helium–neon lasers. Although neon has some applications in plasma tubes ...
Neon tube lighting, which also includes the use of argon and mercury vapor as alternative gases, came to be used primarily for eye-catching signs and advertisements. Neon lighting was relevant to the development of fluorescent lighting, however, as Claude's improved electrode (patented in 1915) overcame "sputtering", a major source of electrode ...
Wu Chi-kai, a veteran neon sign maker, started in the business at age 18 because his father, who installed neon signs for a living, “wanted me to make good use of my time during my summer ...
A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
The colorful neon lights are created when these charged particles collide with atoms and molecules in the planet’s upper atmosphere, according to NOAA.
