Light-loving bulls
The reputation of finding the light lamps in the science world is debated. Historians in the western countries of the Atlantic west, referring to American researcher Thomas Edison, the reputation is attributed to British chemist Joseph swanke.toilet
Finding a light bulb was not found in Sir Joseph swan (England) or bamas Alva Edison (America).
For the first time Sir Humphrey Davy (Sir Humphrey Davy) (England) proved the principle of bright bulls in 1801. Formulation of removing light as it is electrified by a filament. However, as filamentous air immediately burned down, researchers began exploring an air-check filament. In the 19th century, 18 researchers drafted many experimental lighting bulbs before 1879. All of these are renowned by swan and Edison with their experiments.
In the early 1860s swan patented the first experimental bulb with a corchan filament. On December 18, 1878, swan announced the invention of its experimental bulls at a meeting of bain chemical society in new castle. However, the wind was not dry. It continued until January 18, 1879. With this success, swan sundarmond (England) gave his first public appearance, delivering a lecture.
(this is the first time in the world).
During the same period, Edison also conducted research on the invention of lightballs in America. Model no. 9 has been successfully tested. Ten months later the swan experimental performance was completed. Edison to his bulbs on November 1, 1879, to paycent. say
Have applied. Accepted on new issue (1880, January 27, 1880). Swan did not apply a patent until November 27, 1880. Swan applied in America only a year after Edison applied.
Few months before swan began production in England, Edison first invented the world's first commercial lightballs in October 1880. When Edison applied for the British patent, swan patern began a judicial war on the violation of judicial principles.
In 1883, however, the two adjusted outside the court and founded 'edinon and swan united electric cum peney'. Eediswan exchange has marketed name-bullocks.
