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.
The first commercial plasma lamp was an ultraviolet curing lamp with a bulb filled with argon and mercury vapor developed by Fusion UV. That lamp led Fusion Lighting to the development of the sulfur lamp, a bulb filled with argon and sulfur that is bombarded with microwaves through a hollow waveguide. The bulb had to be spun rapidly to prevent ...
William P. Parker is an American artist, scientist, and entrepreneur, best known for inventing the modern design of the plasma globe. [1] The invention occurred in 1971, when Parker was working as a student in a physics laboratory at the Massachusetts Institute of Technology and accidentally filled a test chamber to a greater-than-usual pressure with ionized neon and argon. [2]
Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma. Typically, such lamps use a noble gas ( argon , neon , krypton , and xenon ) or a mixture of these gases.
Crackle tubes get their name not because of the sound they produce but rather because of the appearance of their internal behavior. The "lightning" (filaments or streamers) is forced around and in between the phosphor-coated glass beads, due to the beads' dielectric nature. In so doing, the phosphor is excited by the electrical energy and ...
The energy dissipation in the lamps when they are glowing is very low (about 0.1 W), [31] hence the distinguishing term cold-cathode lighting. Some of the applications of neon lamps include: [31] Pilot lamps that indicate the presence of electrical power in an appliance or instrument (e.g. an electric coffee pot or power supply).
Kmart's longest lasting logo, used from 1969 to 1990. Under the leadership of executive Harry Cunningham, S.S. Kresge Company opened the first Kmart-named store, at 27,000 square feet (2,500 square meters), which was referred to by Kresge as a "bantam" Kmart and was in fact originally intended to be a Kresge store until late in the planning process, on January 25, 1962, in San Fernando ...
Plasma ball may refer to: Plasma globe, a man-made, ball-shaped plasma device; Ball lightning, an atmospheric electrical phenomenon; Star, a luminous spheroid of ...
