Edison Swan
The Edison and Swan Electric Light Company Limited was a manufacturer of incandescent lamp bulbs and other electrical goods. It was formed in 1883 with the name Edison & Swan United Electric Light Company with the merger of the Swan United Electric Company and the Edison Electric Light Company. Thomas Edison established the Edison Electric Light Company in 1878. Joseph Swan established the Swan United Electric Light Company in 1881. Swan sued Edison in the UK, claiming patent infringement; this was upheld by the British courts. In 1882, Edison sued Swan, claiming infringement of his 1879 U.S. patent; however, the Edison Company believed their case would be jeopardized if Swan could demonstrate prior research and publication. Subsequently, in order to avoid uncertain and expensive litigation, the two companies negotiated a merger. The glass bulbs sold in Britain were of Swan's design, while the filaments were of Edison's. From 1887 or earlier Sir Ambrose Fleming was an adviser t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

Vacuum Tubes
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplification and current rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—from the cathode to the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighting Brands
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants. Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects. History With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 years ago, fire was kindl ...

Mazda (light Bulb)
Mazda was a trademarked name registered by General Electric (GE) in 1909 for incandescent light bulbs. The name was used from 1909 to 1945 in the United States by GE and Westinghouse. Mazda brand light bulbs were made for decades after 1945 outside the US. The company chose the name due to its association with Ahura Mazda, the transcendental and universal God of Zoroastrianism whose name means light of wisdom in the Avestan language. In 1909 the Mazda name was created for the tungsten filament light bulb. GE sold bulbs under this trademark starting in 1909. GE promoted the mark as identifying tungsten filament bulbs with predictable performance and life expectancy. GE also licensed the Mazda name, socket sizes, and tungsten filament technology to other manufacturers to establish a standard for lighting. Bulbs were soon sold by many manufacturers with the Mazda name licensed from GE, including British Thomson-Houston in the United Kingdom, Toshiba in Japan, and GE's chief compet ...

La Compagnie Des Lampes
La Compagnie des Lampes ("The Lamp Company") was a name used by several French companies all in the area of electrical products particularly lighting. La Compagnie des Lampes (1888) The original ''Compagnie des Lampes'' was set up at Ivry-sur-Seine in 1888. The plant was subsequently attached to the CGE (Compagnie Générale d'Electricité) on its acquisition in 1898. The plant is classified as a historical monument. In 1915, the plant was the second to start manufacturing ''TM'' triodes ("Télégraphie Militaire") in France, under their ''Métal'' brand (the first was E.C.&A. Grammont (Lyon) under their ''Radio Fotos'' brand). Later they made tubes for domestic AC transformer heating such as thBW604anBW1010under their ''Métal- Secteur'' brand.

Thorn Electrical Industries
Thorn Electrical Industries Limited was a British electrical engineering company. It was listed on the London Stock Exchange, but merged with EMI Group to form Thorn EMI in 1979. It was de-merged in 1996 and became a constituent of the FTSE 100 Index, but was acquired by the Japanese Nomura Group only two years later, it is now owned by Terra Firma Capital Partners. History Sir Jules Thorn founded the company with his business partner Alfred Deutsch in March 1928 as The Electric Lamp Service Company Ltd. Thorn had worked in England as a travelling salesman for company Olso, an Austrian manufacturer of gas mantles. When Olso went bankrupt, Thorn decided to stay in England. Deutsch, an Austrian engineer, visited Thorn in 1928 and was persuaded to stay to help organize the company's production process. Thorn acquired the Atlas Lamp Works company in 1932 and began making light bulbs in Edmonton, North London. The company grew rapidly to become Thorn Lighting, one of the world's la ...

Siemens Brothers
Siemens Brothers and Company Limited was an electrical engineering design and manufacturing business in London, England. It was first established as a branchThe company started with a small factory at 12 Millbank Row, Westminster SW1, London, near the site of Lambeth Bridge in 1858 by a brother of the founder of the German electrical engineering firm Siemens & Halske. The principal works were at Woolwich where cables and light-current electrical apparatus were produced from 1863 until 1968. The site between the Thames Barrier and Woolwich Dockyard has retained several buildings of historic interest.Saint & Guillery, ''The Survey of London vol. 48: Woolwich'', Yale, 2012online PDF pp. 44-53). New works were built at Stafford in 1903 and Dalston in 1908. During World War I Siemens Brothers was bought by a British consortium because most of its ownership was in the hands of enemy aliens; see ''Graces Guide to British Industrial History''.

Sunderland, Tyne And Wear
Sunderland () is a port city in Tyne and Wear, England. It is the City of Sunderland's administrative centre and in the historic county of Durham. The city is from Newcastle-upon-Tyne and is on the River Wear's mouth to the North Sea. The river also flows through Durham roughly south-west of Sunderland City Centre. It is the only other city in the county and the second largest settlement in the North East after Newcastle upon Tyne. Locals from the city are sometimes known as Mackems. The term originated as recently as the early 1980s; its use and acceptance by residents, particularly among the older generations, is not universal. At one time, ships built on the Wear were called "Jamies", in contrast with those from the Tyne, which were known as "Geordies", although in the case of "Jamie" it is not known whether this was ever extended to people. There were three original settlements by the River's mouth which are part of the modern-day city: Monkwearmouth, settled in ...

Ponders End
Ponders End is the southeasternmost part of Enfield, north London, centred on the Hertford Road. Situated to the west of the River Lee Navigation, it became industrialised through the 19th century, similar to the Lea Valley in neighbouring Edmonton and Brimsdown, with manufacturing giving way to warehousing in the late-20th century. The area consists heavily of social housing, with streets also lined with 19th and early-20th century suburban terraced housing. As a result of increased levels of immigration, the area has become the most ethnically diverse part of Enfield, with the majority of the population now belonging to an ethnic minority background as first recorded in the 2011 census. The area is undergoing large-scale regeneration, with the high-rise Alma Road Estate currently undergoing demolition and redevelopment by Countryside Properties. The population of Ponders End was 15,664 as of 2011. Geography Elevations range from to above sea level, uniformly dropping fr ...

Ambrose Fleming
Sir John Ambrose Fleming FRS (29 November 1849 – 18 April 1945) was an English electrical engineer and physicist who invented the first thermionic valve or vacuum tube, designed the radio transmitter with which the first transatlantic radio transmission was made, and also established the right-hand rule used in physics. He was the eldest of seven children of James Fleming DD (died 1879), a Congregational minister, and his wife Mary Ann, at Lancaster, Lancashire, and baptised on 11 February 1850. A devout Christian, he once preached at St Martin-in-the-Fields in London on evidence for the resurrection. In 1932, he and Douglas Dewar and Bernard Acworth helped establish the Evolution Protest Movement. Fleming bequeathed much of his estate to Christian charities, especially those for the poor. He was a noted photographer, painted watercolours, and enjoyed climbing the Alps. Early years Ambrose Fleming was born in Lancaster and educated at Lancaster Royal Grammar School, ...
