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.

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).
A balanced-arm lamp has a base, a stand or body, (in most cases) two connected arms (in many cases fitted with springs), and a lamp-head. The lamp can be moved into almost any position, and the balancing device will maintain the position until moved again. The same overall mechanism can be employed in other devices with similar requirements ...
Nernst lamps did not use a glowing tungsten filament. Instead, they used a ceramic rod that was heated to incandescence.Because the rod (unlike tungsten wire) would not further oxidize when exposed to air, there was no need to enclose it within a vacuum or noble gas environment; the burners in Nernst lamps could operate exposed to the air and were only enclosed in glass to isolate the hot ...
The blowtorch is commonly used where a diffuse (wide spread) high temperature naked flame heat is required but not so hot as to cause combustion or welding.Temperature applications are soldering, brazing, softening paint for removal, melting roof tar, or pre-heating large castings before welding such as for repairing.
To produce enough light, these lamps required the use of extremely long filaments, which remained so until the development of more efficiently wound tungsten filaments. In the 1960s, US inventor Robert (Bob) Kyp patented a similar in appearance but flickering "electric flame" light bulb under the name Balafire [ 6 ] as well as radiometers .
