Lampette
The Lampette was a brand of small electric high-intensity telescoping desk lamps that was designed and distributed by Koch Creations but manufactured by various subcontractors from the early 1960s to the late 1980s. History According to an article published in the June 1965 issue of the Kiplinger's Personal Finance magazine, smaller high-intensity lamps for personal use only came to the market in 1963, after a "professional work light", invented in 1959 by Jay Monroe and then manufactured by Monroe's Tensor Corporation in 1960. The work light was marketed as the "Tensor lamp", and was initially sold to jewelers, watchmakers, and other similar craftsmen. Due to Monroe's and Tensor's success in selling their original type of small high-intensity lamps, other companies began to design and sell similar types of lamps to the general public by 1963. One of the primary competitors of the "Tensor Lamp" throughout the 60s was the Koch Creations "Lampette", which had a similar design and f ...

Tensor Lamp
A Tensor lamp is a trademarked brand of small high-intensity low-voltage desk lamp invented by Jay Monroe. The lamp was mainly popular during the 1960s and 1970s. The lamp was originally used by doctors and dentists, and later became more widely used. Although the first prototype was created in 1959, the lamp was not made available to public until 1960. The brand was manufactured by the Tensor Corporation. History The first Tensor lamp consisted of assembling together a 12-volt automobile parking light bulb and reflector made from an ordinary kitchen measuring cup. Monroe fixed the cup to a metal tube that was attached to a transformer, which reduced 115-volt house current to 12 volts. Because of the small bulb, the entire lamp could be made smaller with a light-directing shade. Monroe was issued a patent for his invention. By 1963, the lamp was sold to the general public as a decorative desk lamp for home and office when several other manufacturers entering the field. The main c ...

Light Fixture
A light fixture (US English), light fitting (UK English), or luminaire is an electrical device containing an electric lamp that provides illumination. All light fixtures have a fixture body and one or more lamps. The lamps may be in sockets for easy replacement—or, in the case of some LED fixtures, hard-wired in place. Fixtures may also have a switch to control the light, either attached to the lamp body or attached to the power cable. Permanent light fixtures, such as dining room chandeliers, may have no switch on the fixture itself, but rely on a wall switch. Fixtures require an electrical connection to a power source, typically AC mains power, but some run on battery power for camping or emergency lights. Permanent lighting fixtures are directly wired. Movable lamps have a plug and cord that plugs into a wall socket. Light fixtures may also have other features, such as reflectors for directing the light, an aperture (with or without a lens), an outer shell or housing f ...

Tizio
Tizio is a desk lamp created by Richard Sapper for Artemide in 1972. It was selected for the Compasso d'Oro industrial design award in 1979. An item of it is part of the collections of the Metropolitan Museum of Art and of the Museum of Modern Art. The position and the direction of the bulb can be adjusted; thanks to two counterweights, moving it requires little effort. There are no wires between the base and the lamp: the two parallel arms, connected with snap fasteners, conduct safe 12-volt electricity. The bulb is halogen, which was previously mainly used in the automotive industry. The Tizio is available in a variety of sizes and colours; the original, and most widely known, is the 50 (referring to the wattage of the bulb) in black. The mid-sized model is the 35, and there is the bedside-sized Micro (20 Watts). Other colours are white, and grey metallic; and, the occasional limited edition in polished aluminium, or titanium-colour. There also is a floorstanding version, the ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Tolomeo Desk Lamp
The Tolomeo incandescent desk lamp is an icon of Italian modern design. It was designed by Michele De Lucchi and Giancarlo Fassina in 1986 for the Artemide company. It won the Compasso d'Oro design prize in 1989. It is a balanced-arm lamp with external steel tension cables attached to springs hidden inside the arms. Its original configuration was a desk lamp with a heavy base, two straight polished aluminium arm sections (each approximately 45 cm long), and a matte aluminium reflector head which can swivel 360°. Many variants are now produced, including floor lamps and wall sconces. ''Tolomeo'' is the Italian version of the name Ptolemy. It is sometimes considered as the successor of Artemide's Tizio lamp, with the advantages of a swiveling shade. In the dot-com period, it became popular as a symbol of conspicuous consumption and high design consciousness in high-tech companies as well as in architectural and graphic design Graphic design is a profession, academic d ...

Banker's Lamp
The banker's lamp is a style of electric desk or table lamp often characterized by a brass stand, green glass lamp shade, and pull-chain switch. Such a lamp was first patented in the United States under the Emeralite brand name. These types of lamp are frequently used in libraries throughout the United States, which have made the lamp popular through their presence in films and TV series. Other examples can feature different colours of glass, and alternate switch types. History The first patent for a banker's lamp was filed on 11 May 1909 by Harrison D. McFaddin, and were produced and sold under the brand name Emeralite ("emerald" and "light"). Emeralite lamp shades were produced by the J. Schreiber & Neffen factory located in the city of Rapotín, Moravia. Later competitors were sold as "Greenalite", "Verdelite", and "Amronlite". A British version of the banker's lamp was filed for a patent in 1929, which, instead of a glass shade, has a solid brass shade or reflector. In ...

Balanced-arm Lamp
A balanced-arm lamp, sometimes called a floating arm lamp, is a lamp with an adjustable folding arm which is constructed such that the force due to gravity is always counteracted by springs, regardless of the position of the arms of the lamp. Many lamp brands (such as the Anglepoise, originator of the concept, and Luxo L-1), as well as other devices, use this principle. Configuration The five terms This article uses the terminology: * ''lamp cap'', * ''forearm'', * ''upper arm'', * ''stand'' or ''body'' and * ''base'' for the five basic parts of these lamps. The general design 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, such as: * copy holders for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Kiplinger's Personal Finance
''Kiplinger's Personal Finance'' ( ) is an American personal finance magazine published by Kiplinger since 1947. It claims to be the first American personal finance magazine and to deliver "sound, unbiased advice in clear, concise language". It offers advice on managing money and achieving financial security, saving, investing, planning for retirement, paying for college, and major purchases like automobiles and homes. History W.M. Kiplinger, founder of the Kiplinger family of publications, said he founded the magazine because "The times will always be changing. Much of life and work consists of looking for the changes in advance and figuring out what to do about them." Upon initial production, the magazine was known simply as ''Kiplinger Magazine'', changing its name to ''Changing Times: The Kiplinger Magazine'' in 1949 and acquiring its present name in 1991. Much like ''Forbes'' magazine, ownership of the Kiplinger's franchise was kept in the family until the sale of Kiplinger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lumen (unit)
The lumen (symbol: lm) is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units (SI). Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths. One lux is one lumen per square metre. The lumen is defined in relation to the candela as : 1 lm = 1 cd· sr. A full sphere has a solid angle of 4π steradians, so a light source that uniformly radiates one candela in all directions has a total luminous flux of :. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
