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 ...

Lamp (electrical Component)
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a Bayonet mount, bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a Incandescent light bulb#Filament, filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, such as fluorescent lamps, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor. Before electric lighting became common in the early 20th century, people used candles, gas lighting, gas lights, oil lamps, and fires. Vasily Vladimirovich Petr ...

Illuminating Engineering Society
The Illuminating Engineering Society (IES), formerly the Illuminating Engineering Society of North America (IESNA), is an industry-backed, not-for-profit, learned society that was founded in New York City on January 10, 1906. The IES's stated mission is "to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public". The Society is still headquartered in New York City, with offices at 120 Wall Street. The IES is divided into approximately 100 local sections. Publications The IES is credited with over 100 publications on the subject of lighting such as ''The Lighting Handbook: 10th Edition''. Other publications, many of which are American National Standards Institute (ANSI) or ASHRAE standards, include recommended practices for a variety of specific lighting applications such as office, sports, and outdoor lighting, and lighting for healthcare facilities.

Anglepoise Lamp
The Anglepoise lamp is a balanced-arm lamp designed in 1932 by British designer George Carwardine. History and development George Carwardine (1887–1947) was a car designer and, at the same time he invented the Anglepoise lamp, (as a freelance) design consultant specialising in vehicle suspension systems. While developing new concepts for vehicle suspensions, he created a mechanism which he recognised had applications in other fields. He particularly saw its benefits for a task lamp. Despite many claims to the contrary, his concept had nothing whatsoever to do with mimicking the actions of the human arm. The joints and spring tension allow the lamp to be moved into a wide range of positions which it will maintain without being clamped. Carwardine applied to be a patent, number 404,615, for a design using the mechanism on 4 July 1932, and manufactured the lamp himself in the workshops of his own company, Cardine Accessories, in Bath. He soon found the interest and demand so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Metropolitan Museum Of Art
The Metropolitan Museum of Art of New York City, colloquially "the Met", is the largest art museum in the Americas. Its permanent collection contains over two million works, divided among 17 curatorial departments. The main building at 1000 Fifth Avenue, along the Museum Mile on the eastern edge of Central Park on Manhattan's Upper East Side, is by area one of the world's largest art museums. The first portion of the approximately building was built in 1880. A much smaller second location, The Cloisters at Fort Tryon Park in Upper Manhattan, contains an extensive collection of art, architecture, and artifacts from medieval Europe. The Metropolitan Museum of Art was founded in 1870 with its mission to bring art and art education to the American people.
