Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light . A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure.
Neon hydrate or neon clathrate, a clathrate, can form in ice II at 480 MPa pressure between 70 K and 260 K. [26] Other neon hydrates are also predicted resembling hydrogen clathrate, and those clathrates of helium. These include the C 0, ice I h and ice I c forms. [26] Neon atoms can be trapped inside fullerenes such as C 60 and C 70.
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 primary reason for eventual neon tube failure is the slow absorption of neon gas into the glass walls, but even this process can take over 50 years. This extended lifespan makes neon lights ideal for architectural lighting in homes, where they can be shaped to fit tight spaces and provide years of illumination.
Neon is used in making advertising signs. Neon gas in a vacuum tube glows bright red in colour when electricity is passed through. Different coloured neon lights can also be made by using other gases. [6] Helium gas is mainly used to fill hot air and party balloons. Balloons filled with it float upwards and this phenomenon is achieved as helium ...
Neon lighting, a widely used form of cold-cathode specialty lighting consisting of long tubes filled with various gases at low pressure excited by high voltages, used as advertising in neon signs. Low pressure sodium lamps , the most efficient gas-discharge lamp type, producing up to 200 lumens per watt, but at the expense of very poor color ...
The neon available for purchase for a neon-sign shop often comes in glass flasks at the pressure of a partial vacuum. These cannot be used to fill a ball with a useful mixture. Tanks of gas, each with its specific, proper, pressure regulator and fitting, are required: one for each of the gases involved.
