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."
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 ...
Multistate noise looks somewhat like flicker ( ) noise. The effect is process dependent, but it can be minimized. Diodes may also be selected for low multistate noise. [10] A commercial example of an avalanche diode noise generator is the Agilent 346C that covers 10 MHz to 26.5 GHz. [11]
Illustration of St. Elmo's fire on a ship at sea Electrostatic discharge flashes across the windscreen of a KC-10 cockpit.. St. Elmo's fire (also called witchfire or witch's fire) [1] is a weather phenomenon in which luminous plasma is created by a corona discharge from a rod-like object such as a mast, spire, chimney, or animal horn [2] in an atmospheric electric field.
A plasma ball with filaments extending between the inner and outer spheres. A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with noble gases, usually a mixture of neon, krypton, and xenon, that has a high-voltage electrode in the center of the container.
"Neon" is used to denote the general type of lamp, but neon gas is only one of the types of tube gases principally used in commercial application. Pure neon gas is used to produce only about one-third of the colors (mostly shades of red and orange, and some warmer or more intense shades of pink).
By using a square-wave output that is not referenced to the line cycle rate, a flicker-free output can be produced. Since the IGBTs switch on and off at a regulated cycle rate, a generator can be slightly off-speed and the lamp will still be flicker-free, which is not the case with a standard magnetic ballast.
The 4th generation of LED tubes offers a solution to the flickering problem. The flickering is measured using so-called flicker index or flicker percentage value. Elimination of flickering allows high-quality video recording and slow motion capture, as well as certain machine vision applications in premises equipped with flicker-free lights. [3 ...
