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 ...
Leviton was founded in 1906 by Russian immigrants Evser Leviton and his son Isidor Leviton when they began manufacturing brass mantle tips for natural gas lights in Manhattan's Lower East Side. [ 2 ] [ 3 ] [ 4 ] In 1910, Isidor designed a screw-in lampholder for the newly invented electric light bulb and within ten years the lampholders were ...
Welsbach's first company established a factory in Atzgersdorf in 1887, but it failed in 1889. In 1889, Welsbach received his first patent mentioning thorium (March 5, 1889, US patent #399,174). In 1891 he perfected a new mixture of 99% thorium dioxide and 1% cerium dioxide that gave off a much whiter light and produced a stronger mantle. After ...
Acetylene was also used from about 1898 for gas lighting on a smaller scale. [33] Illuminating gas was used for gas lighting, as it produces a much brighter light than natural gas or water gas. Illuminating gas was much less toxic than other forms of coal gas, but less could be produced from a given quantity of coal.
In its simplest form, it consists of two electrodes in a cell held at low pressure (0.1–10 torr; about 1/10000 to 1/100 of atmospheric pressure). A low pressure is used to increase the mean free path ; for a fixed electric field, a longer mean free path allows a charged particle to gain more energy before colliding with another particle.
15 kW xenon short-arc lamp used in IMAX projectors High-speed, slow-motion video of a xenon flashtube recorded at a speed of 44,025 frames per second.. A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure.
A pyrotechnic composition is a substance or mixture of substances designed to produce an effect by heat, light, sound, gas/smoke or a combination of these, as a result of non-detonative self-sustaining exothermic chemical reactions. Pyrotechnic substances do not rely on oxygen from external sources to sustain the reaction.
Xenon flashtubes have been used to produce an intense flash of white light, some of which is absorbed by Nd:glass that produces the laser power for inertial confinement fusion. In total about 1 to 1.5% of the electrical power fed into the flashtubes is turned into useful laser light for this application.
