Units industrial electric lamps
Along with the fact that LED lights can dramatically cut the cost of lighting a large unit, they can also provide your business with the following benefits:. Often, industrial units require a constant and reliable stream of high quality, bright lighting. Unlike traditional incandescent or halogen light bulbs, LEDs offer some of the brightest glows; making them ideal for larger units. In industrial units that require constant lighting all-year round, you may grow to be concerned about the amount of ultraviolet UV or infrared IR radiation that is being emitted from traditional light bulbs. Industrial units with a large amount of internal space can use LED lights as their first source of lighting, implementing them within the existing lights of the property. You can also install LED lighting in any external areas of the property, such as outside sheds and working spaces.VIDEO ON THE TOPIC: Lunera's Helen Lamp from All Industrial Electric Supply

Lamps & Lighting
The social and economic impact of the electric power and light industry, which began its rapid development during the last quarter of the nineteenth century, has been so great that some refer to the twentieth century as the "Age of Electricity. The success of the electrical industry in supplanting older methods of providing illumination and mechanical power—such as the gaslight and the steam engine —was the result of the ease and economy with which companies could generate and transmit over long distances large quantities of electrical energy and then convert it into heat, light, or motion.
Although the electric power and light industry did not reach a level of commercial importance until near the end of the nineteenth century, there were notable related scientific and technological developments prior to One of the earliest electric motors developed in America was the "electrical jack," primarily a philosophical toy, described by Benjamin Franklin in Franklin and other colonial natural philosophers also commonly used tribo-electric or frictional electrostatic generators.
In the American Joseph Henry devised a small motor that produced a rocking motion and developed powerful electromagnets capable of lifting up to 3, pounds. Thomas Davenport, a Vermont blacksmith, built several electric direct-current rotary motors during the s and used them to drive woodworking tools, a printing press, and a small "electric train. Page of Washington, D. Nevertheless, by the s most observers recognized that the electric motor required a more efficient and inexpensive source of electrical energy than the battery before it could threaten the dominance of the steam engine.
An alternative to the voltaic battery as a source of electrical current had been available in principle since Michael Faraday 's discovery of electromagnetic induction in This discovery led to the development of magnetogenerators, which converted mechanical motion into electricity.
Joseph Saxton of Washington, D. Magnetogenerators began to be used for arclights in lighthouses after about Several major changes in the design of the magnetogenerator culminated in the invention of the more efficient self-excited generator, or dynamo, during the s. Used both as a generator and as a motor, the Philadelphia Centennial Exposition of prominently featured a Gramme dynamo built by William A. Anthony, a Cornell University professor, probably the first dynamo built in America. In the same year Thomas A.
Edison established his famous laboratory at Menlo Park, New Jersey , which became the center for the creation of his incandescent light and power system. The arc-lighting industry became the first sector of the electric light and power industry to achieve a substantial commercial success, largely replacing the gaslight industry for street lighting in urban areas.
Charles F. Brush of Cleveland, Ohio, became the pioneer innovator in arc lighting in America. His first commercial installation was in Philadelphia in , and several other cities, including San Francisco , soon adopted the Brush system. Numerous competitors soon entered the field, including Elihu Thomson's and E. Thomson pioneered several improvements in arc lighting, including an automatic current regulator and a lightning arrester, and Sperry devised a current regulator and invented an automatic regulator of electrode spacing in the arclight.
Sperry was also responsible for a spectacular installation of arc lights located at the top of a foot tower on the Board of Trade Building in Chicago that could be seen from sixty miles away. The Thomson-Houston Company came to dominate the industry by , with the number of arclights in use growing to about , in , by which time incandescent gas and electric lights both provided strong competition.
Edison and his associates at Menlo Park were largely responsible for the introduction of a successful incandescent lighting system. Edison already enjoyed a reputation as an inventor of telegraph instruments when he turned his attention to the problem of indoor electric lighting in The Edison Light Company attracted substantial financial support from J. Morgan and other investment bankers, who spent a half-million dollars before the Edison system achieved commercial success. After a study of the gaslight industry, Edison decided that a high-resistance lamp was necessary for the economical subdivision of electricity generated by a central station.
A systematic search for a suitable lamp resulted in the carbon-filament high-vacuum lamp by late The Menlo Park team also developed a series of dynamos of unprecedented efficiency and power capacity, such as the "Jumbo Dynamo," which provided power for 1, lamps.
The first public demonstration of the new system was held at Menlo Park on 31 December , and the first commercial central station, located on Pearl Street in New York City, began operation in Three separate manufacturing companies produced lamps, dynamos, and transmission cables, but were combined in to form the Edison General Electric Company.
The subsequent merger of this company with the Thomson-Houston Company in resulted in the General Electric Company. By the early s electrical journals, regional and national societies devoted to electrical technology, national and international exhibitions of electrical apparatuses, and new academic programs in electrical science and engineering proliferated in recognition of the new industry's economic potential.
George Westing house pioneered the introduction of a competing incandescent lighting system using alternating current , which proved to have decisive advantages over the Edison direct-current system. A key element of the new system was the transformer, which increased a generator's voltage to any desired amount for transmission to remote points, where another transformer then reduced the voltage to a level suitable for lamps.
This feature overcame the major limitation of the direct-current distribution system, which could provide energy economically only at distances of a mile or less from the generator. Westing house, who had considerable experience in manufacturing railway-signaling devices and in natural-gas distribution, organized the Westing house Electric Company in to begin the manufacture of transformers, alternators, and other alternating-current apparatus.
Westing house opened the first commercial installation in Buffalo, New York , late in Shortly thereafter the Thomson-Houston Company entered the field and was Westing house's only serious competitor in America until the formation of General Electric. The advent of the Westing house alternating-current system precipitated the "battle of the systems," during which spokesmen of the Edison Company argued that alternating current was much more dangerous than direct current and even used Westing house generators to electrocute a convicted murderer in But the economic advantages of alternating current soon settled the matter.
By more than five hundred alternating-current central stations operated in the United States alone, boosting the number of incandescent lamps in use to 18 million by During the late s, urban streetcar systems, which had previously depended on horses or cables, began to electrify their operations.
Frank J. Sprague had developed an efficient fifteen-horsepower direct-current motor by and obtained a contract to build a forty-car system in Richmond, Virginia, in The Richmond installation, which began operation the following year, became the prototype for the industry, which spread to all major American cities before the end of the century. The Westing house Company began to manufacture railway motors in , followed by General Electric in These two companies soon dominated the field: Westing house had produced about twenty thousand railway motors by , and General Electric, about thirty thousand.
Sprague continued to improve his system and won the contract for the electrification of the South Side Elevated Railway in Chicago in His company was purchased by General Electric in The next major innovation in electric motors and generators was the introduction of alternating-current machines during the s.
The Westing house Company acquired the strategic alternating-current motor patents of the Serbian immigrant Nikola Tesla and became the leading American firm in exploiting the new technology. In particular, the company developed practical alternating-current motors for use in interurban railroads and in industry. In the company installed a single-phase system to supply a hundred-horsepower motor near Telluride, Colorado, and built a large display at the World's Columbian Exposition in Chicago.
In October of the same year, Westing house received the contract to construct the generating equipment for the famous Niagara Falls Power project. The project successfully generated an enormous amount of power and transmitted it up to twenty miles from the site, clearly establishing the superiority of alternating current for hydroelectric power and opening the prospect that previously inaccessible sites might be exploited.
The availability of cheap electric power at Niagara stimulated the rapid growth of a number of energy-intensive electrochemical industries in the vicinity. The growth of the alternating-current power and lighting industry also stimulated the work of Charles P. Steinmetz, who joined the General Electric Company as an electrical engineer in and who presented a classic paper on the use of complex algebra in alternating-current analysis at the International Electrical Congress in Chicago the same year.
He also formulated a law of magnetic hysteresis that became a basis for the rational design of transformers and alternators. Sidney B. Paine of General Electric was responsible for the first major use of alternating-current motors in industry.
He persuaded the owners of a new textile factory in Columbia, South Carolina , to abandon the traditional system of belting and shafting powered by giant steam engines in favor of textile machines using polyphase induction motors. In this instance the constant speed of the motors was a distinct advantage, and the new system soon spread throughout the industry.
Direct-current motors remained in wide use in applications requiring variable speed, such as in steel mills and in machine tooling. By almost , industrial motors were being manufactured per year, more than half of the alternating-current type.
Nearly every industry in the country had installed electric motors by the beginning of World War I. One of the most significant events in the history of the electric light and power industry was the introduction of high-speed turboelectric generators in central power stations during the first decade of the twentieth century. By the unit capacity of alternators driven by the reciprocating steam engine had reached a practical limit of around five thousand kilowatts with giant thirty-foot rotors weighing up to two hundred tons and driven at speeds of around seventy-five revolutions per minute.
The new turbogenerators were much more compact for the same capacity and could be built for much greater output power. However, the higher speeds of the turbogenerators up to two thousand revolutions per minute necessitated the use of stronger materials, such as nickel-steel alloys, that could withstand the increased mechanical stresses.
New rotor designs were also necessary to reduce air resistance and improve ventilation. Both Westing house and General Electric decided to manufacture their own turbines based on the patents of C.
Parsons and G. Curtis, respectively. General Electric built the first large commercial installation, a five-thousand-kilowatt unit, for the Commonwealth Edison Company of Chicago in In the company replaced it with a twelve-thousand-kilowatt turbogenerator. Of the 1. Turboelectric generators made possible significant economies of scale, making it more economical for most consumers to purchase electric power from central generating stations than to install their own isolated generating plants.
The history of the turbogenerator since has been one of steady increase in the maximum size of units and a concomitant reduction in the consumption of fuel per unit of energy generated.
Another "battle of the systems" broke out in the first two decades of the twentieth century—this time between steam and electric locomotives. In this case the older steam technology won out. Most of the electrified inter-urban transportation operated in areas having high population density or requiring tunnels, where the smoke from steam locomotives presented problems.
The mileage of "electrified track" jumped from in to about 3, in After a fairly rapid growth in track mileage during the period —, alternating-current rail systems plateaued until the electrification of the New York—Washington, D. In contrast, the steam railroad mileage increased steadily at the rate of about six thousand miles per year from to the beginning of World War I , reaching a total of about , miles in The steam locomotive was supplanted during the period — by the diesel-electric locomotive, in which the power for the electric drive motors was locally generated by diesel-powered electric generators.
Developments in power electronics since have created a renewed interest in electric locomotives powered from remote central stations. Another major trend in the electric power industry during the twentieth century has been toward higher transmission voltages, which increase the distances over which electrical energy can be transmitted economically. The introduction of the suspension insulator in soon enabled transmission voltages of the order of kilovolts to become common.
The adoption of kilovolts as a standard transmission line voltage in the s made feasible transmission distances of more than three hundred miles. Coincident with the development of techniques that have made possible the production of large quantities of electrical energy at a single location and its efficient transmission over high-voltage lines was a rising concern for the conservation of nonrenewable resources, such as coal.
This concern, which crested just prior to World War I, led to the formulation of a policy for the rational development of the nation's hydroelectric power resources. This policy was articulated by conservationists—notably Gifford Pinchot and W.
McGee—and supported by leading engineers.

ELECTRIC POWER AND LIGHT INDUSTRY
It's been nearly a year since cash-strapped GE revealed plans to sell the struggling light bulb business and focus instead on moneymakers like jet engines and MRI machines. But GE GE has yet to find a taker for the iconic unit. The company is in "active discussions" with potential suitors for the lighting division, CEO John Flannery told analysts during a conference call last month. However, no concrete deal has been reached yet. Even as GE has moved forward with sales of other storied businesses like the year-old rail division, the company declined to provide CNNMoney this week with an update on efforts to sell GE Lighting. The struggle to sell the light bulb unit underscores the dim outlook for the lighting industry that GE and the conglomerate's cofounder Thomas Edison pioneered. GE has decided to shift focus onto three core areas: healthcare, power and aviation. The lighting slump isn't special to GE, which has also been grappling with troubles in its insurance , power and transportation businesses. It's an industrywide problem driven by low prices and the popularity of LED lights that last for decades, limiting the need to replace them. Related: GE's latest sale: Its year-old rail business.

An electric light is a device that produces visible light from electric current. It is the most common form of artificial lighting and is essential to modern society,  providing interior lighting for buildings and exterior light for evening and nighttime activities. In technical usage, a replaceable component that produces light from electricity is called a lamp. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a filament heated white-hot by electric current, gas-discharge lamps , which produce light by means of an electric arc through a gas, 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 lights , oil lamps , and fires.

Беккер задумался: Я бы хотел, чтобы ты как следует вымыл голову, научился говорить по-человечески и нашел себе работу. Но решил, что хочет от этого парня слишком многого. - Мне нужна кое-какая информация, - сказал. - Проваливал бы ты отсюда.
Я понимаю, но… - Сегодня у нас особый день - мы собирались отметить шесть месяцев. Надеюсь, ты помнишь, что мы помолвлены. - Сьюзан - вздохнул он - Я не могу сейчас об этом говорить, внизу ждет машина. Я позвоню и все объясню. - Из самолета? - повторила. - Что происходит. С какой стати университетский профессор… Это не университетские дела.
