![]() He eventually produced a bulb that could produce light for over 1500 hours. In 1879, American Thomas Edison adopted Swan's incandescent light bulb using a carbon filament in an oxygen-free bulb after failures with other designs. In 1881 he had started his own company, The Swan Electric Light Company, and started commercial production. His house Underhill on Kells Lane in Low Fell, Gateshead was the first in the world to have working light bulbs installed. Starting that year he began installing light bulbs in homes and landmarks in England. ![]() Swan had reported success to the Newcastle Chemical Society and at a lecture at Sunderland Technical College in February 1879, he demonstrated a working lamp. Swan received a British patent for his device in 1878, about a year before Thomas Edison. The most significant feature of Swan's improved lamp was that there was little residual oxygen in the vacuum tube to ignite the filament, thus allowing the filament to glow almost white-hot. Fifteen years later, in 1875, Swan returned to consider the problem of the light bulb with the aid of a better vacuum and a carbonized thread as a filament. In 1850 he began working on a light bulb using carbonized paper filaments in an evacuated glass bulb.īy 1860 he was able to demonstrate a working device and obtained a British patent covering a partial vacuum, carbon filament incandescent lamp. ![]() ![]() The first successful incandescent light bulb was made by the British inventor Sir Joseph Swan. While conversion of electrical energy to light was demonstrated in laboratories as early as 1801 by English scientist Humphry Davy, it took more than 100 years for the modern form of the electric light bulb to be developed, with the contributions of many inventors. ![]() Incandescent light bulb An incandescent light bulb with a glowing filament. 2.8 What idea(s) and/or inventions had to be developed before it could be created?.1.8 What ideas and/or inventions had to be developed before it could be created?. ![]()
