The History Of Incandescent Lamps
Dec 28, 2017

People have been using incandescent bulbs for more than more than 130 years. As early as Edison, the British electrical Engineer Swan (J.swan) began in the late 1840s to carry out the study of Electric light. After nearly 30 years of hard work, Swan finally found the carbon wire suitable for the filament.

The invention of incandescent lamps, the United States is usually credited to Edison, Britain is due to swan. The competition for two inventors is fierce, patent disputes are almost inevitable, and later, the two men reached an agreement to build the Edison-Swan Electric Company to produce incandescent lamps in the UK.

In 1845, the Cincinnati Starr proposed the use of carbon wire in a vacuum bubble. British Swan in this way, with a strip of carbonized paper as a filament, trying to make the current through it to glow, but, because the vacuum technology is still poor, the residual air in the bulb, so that the filament quickly burned. As a result, the lamp has a very short life span of only one or two hours and is not of practical value.

The advent of the vacuum pump in 1878 made it necessary for Swan to carry out the study of incandescent light again.

December 18, 1878, Swan successfully produced the first incandescent electric bubble. Shortly thereafter, he showed his carbon filament bulbs at the Newcastle Chemical Society. And when his experimental report on Lamp was published in the United States, Edison was given direct help.
