17 However, having perfected the device to his own satisfaction, he turned to the problem of wireless telegraphy and did not develop the electric light any further. His claims are not well documented, although he is credited in Challoner. With being the inventor of the "Incandescent Light Bulb". 17 In 1838, belgian lithographer Marcellin Jobard invented an incandescent light bulb with a vacuum atmosphere using a carbon filament. 18 In 1840, British scientist Warren de la rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain fewer gas molecules to react with the platinum, improving its longevity. Although a workable design, the cost of the platinum made it impractical for commercial use. In 1841, Frederick de moleyns of England was granted the first patent for an incandescent lamp, with a design using platinum wires contained within a vacuum bulb.

Other inventors with generators and incandescent lamps, and with comparable ingenuity and excellence, have long been forgotten because their creators did not preside over their introduction in a system of lighting. Hughes, In Technology at the turning point, edited. Pickett 9 10 Timeline of the early evolution of the light bulb 11 Early pre-commercial research Original carbon-filament bulb from Thomas Edison 's shop in Menlo park In 1761 Ebenezer Kinnersley demonstrated heating a wire to incandescence. 12 In 1802, humphry davy used what he described as " a battery of immense size 13 consisting of 2,000 cells housed in the basement of the royal Institution of Great Britain, 14 to create an incandescent light by passing the current through a thin. It was not bright enough nor did it last long enough to be practical, but it was the precedent behind the efforts of scores of experimenters over the next 75 years. 15 over the first three-quarters of the 19th century, many experimenters worked with various combinations of platinum or iridium wires, carbon rods, and evacuated or semi-evacuated enclosures. Many of these devices were demonstrated and some were patented. 16 In 1835, james Bowman Lindsay demonstrated a constant electric light at a public meeting in Dundee, scotland. He stated that he could "read a book at a distance of one and a half feet". Lindsay, a lecturer at the watt Institution in Dundee, scotland, at the time, had developed a light that was not combustible, created no smoke or smell and was less expensive to produce than davy's platinum-dependent bulb.

deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, 4 heat lights for reptile tanks, 5 infrared heating for industrial heating and drying processes, lava lamps, and the easy-bake oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting leds. Incandescent bulbs have been replaced in many applications by other types of electric light, such as fluorescent lamps, compact fluorescent lamps (cfl cold cathode fluorescent lamps (ccfl high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the european Union, China, canada and United States, are in the process of phasing out the use of incandescent light bulbs while others, including Colombia, 6 Mexico, cuba, argentina and Brazil, 7 have prohibited them already. Contents History In addressing the question of who invented the incandescent lamp, historians Robert Friedel and paul Israel list 22 inventors of incandescent lamps prior to joseph Swan and Thomas Edison. 8 They conclude that Edison's version was able to outstrip the others because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve (by use of the Sprengel pump ) and a high resistance that made. Historian Thomas Hughes has attributed Edison's success to his development of an entire, integrated system of electric lighting. The lamp was a small component in his system of electric lighting, and no more critical to its effective functioning than the Edison Jumbo generator, the Edison main and feeder, and the parallel-distribution system.

The light bulb is supplied with electric current by feed-through terminals or wires embedded powerplus in the glass. Most bulbs are used in a socket which provides mechanical support and electrical connections. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. As a result, the incandescent bulb is widely used in household and commercial lighting, for portable lighting such as table lamps, car headlamps, and flashlights, and for decorative and advertising lighting. Incandescent bulbs are much less efficient than other types of electric lighting; incandescent bulbs convert less than 5 of the energy they use into visible light, 1 with standard light bulbs averaging about.2. 2, the remaining energy is converted into heat.
