Plasma globe. 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. When voltage is applied, a plasma is formed ...
A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
Color theory shows that mixing the primary colors of light will make white light. Therefore, through color mixing, LED's can form a wide variety of colors from white light to deep primary colors to many others. This reduces the time taken to change the color of an already hung fixture.
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...
Various governments have passed legislation to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy- efficient alternatives. The regulations are generally based on efficiency, rather than use of incandescent technology. However, it is not unlawful to continue to buy or sell existing ...
The color temperature of a light source is the temperature of a black body that has the same chromaticity (i.e. color) as the light source. A notional temperature, the correlated color temperature, the temperature of a black body that emits light of a hue that to human color perception most closely matches the light from the lamp, is assigned.
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 ...
The sulfur lamp (also sulphur lamp) is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation. They are a particular type of plasma lamp, and one of the most modern. The technology was developed in the early 1990s and appeared promising, but was not a ...
