Compagnie Industrielle Française Des Tubes Electroniques
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 the BW604 and BW1010 under their ''Métal- Secteur'' brand. La Compagnie des Lampes (1911) Founded in 1911 by Paul Blavier, ''La Compagnie des Lampes'' was a light bulb factory workshop, located in Saint-Pierre-Montlimart, near Cholet. The company changed its name in 1918 to become ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Engineering Companies Of France
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

Thermionic Valve
Thermionic emission is the liberation of charged particles from a hot electrode whose thermal energy gives some particles enough kinetic energy to escape the material's surface. The particles, sometimes called ''thermions'' in early literature, are now known to be ion source, ions or electrons. Thermal electron emission specifically refers to emission of electrons and occurs when thermal energy overcomes the material's work function. After emission, an opposite charge of equal magnitude to the emitted charge is initially left behind in the emitting region. But if the emitter is connected to a Electric battery, battery, that remaining charge is neutralized by charge supplied by the battery as particles are emitted, so the emitter will have the same charge it had before emission. This facilitates additional emission to sustain an electric current. Thomas Edison in 1880 while inventing Edison light bulb, his light bulb noticed this current, so subsequent scientists referred to the cur ...

Edison And Swan Electric Light Company
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planned Obsolescence
In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is the concept of policies planning or designing a good (economics), product with an artificially limited Product lifetime, useful life or a purposely frail design, so that it becomes obsolete after a certain predetermined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as fashion, unfashionable. The rationale behind this strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle"). It is the deliberate shortening of the lifespan of a product to force people to purchase functional replacements. Planned obsolescence tends to work best when a producer has at least an oligopoly. Before introducing a planned obsolescence, the producer has to know that the customer is at least somewhat likely to buy a replacement from them in ...

Phoebus Cartel
The Phoebus cartel was an international cartel that controlled the manufacture and sale of incandescent light bulbs in much of Europe and North America between 1925 and 1939. The cartel took over market territories and lowered the useful life of such bulbs, which is commonly cited as an example of planned obsolescence. Corporations based in Europe and the United States, including Tungsram, Osram, General Electric, Associated Electrical Industries, and Philips, incorporated the cartel on January 15, 1925 in Geneva, as ''Phœbus S.A. Compagnie Industrielle pour le Développement de l'Éclairage'' (French for "Phoebus plc Industrial Company for the Development of Lighting"). Although the group had intended the cartel to last for thirty years (1925 to 1955), it ceased operations in 1939 with the outbreak of World War II. Following its dissolution, light bulbs continued to be sold at the 1,000-hour life standardized by the cartel. History Osram, Philips, Tungsram, Associated ...

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 Electric (1886), 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 Electrical filament, 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 Unite ...

Zoroastrian Fire Pot
Zoroastrianism ( ), also called Mazdayasnā () or Beh-dīn (), is an Iranian religion centred on the Avesta and the teachings of Zarathushtra Spitama, who is more commonly referred to by the Greek translation, Zoroaster ( ). Among the world's oldest organized faiths, its adherents exalt an uncreated, benevolent, and all-wise deity known as Ahura Mazda (), who is hailed as the supreme being of the universe. Opposed to Ahura Mazda is Angra Mainyu (), who is personified as a destructive spirit and the adversary of all things that are good. As such, the Zoroastrian religion combines a dualistic cosmology of good and evil with an eschatological outlook predicting the ultimate triumph of Ahura Mazda over evil. Opinions vary among scholars as to whether Zoroastrianism is monotheistic, polytheistic, henotheistic, or a combination of all three. Zoroastrianism shaped Iranian culture and history, while scholars differ on whether it significantly influenced ancient Western philoso ...
