October 21 Invented the high-resistance incandescent lamp, which lit continuously for 40 hours. November 1 patented the carbon filament lamp. December 21, The New York Express reported on Edison's incandescent electric lamp. December On the 25th, 3,000 visitors from New York City gave a public electric light show in Monroe Park.
1880, working on helicopters. Patented the invention of the electric lamp. On January 28, the patent for \"electric power transmission and distribution system\" was proposed. On February 18, Scripper Monthly published the article \"Edison's Electric light\
In 1881, New York opened its Fifth Avenue headquarters. Set up an incandescent lamp factory in New York. Set up manufacturing plants for generators, underground wiring, light parts. Testing the streetcar in Monroe Park.

On May 23, 1885, he filed a patent for wireless telegraphy.
From 1887 to 1890, he improved the cylinder phonograph and obtained more than 80 patents on the phonograph. Operating phonograph, record, speaker and other manufacturing and distribution business.
In 1888, he invented the phonograph.
In 1889, he participated in the Centennial Exposition in Paris. Invented a variety of electric railways. Complete the motion movie machine.
1890-1899 Design of large stone crusher, grinding machine. In 1891, he invented the Edison Concentrator and started his own mining business. Patented for a \"motion picture Projector\
In 1893, the world's first film \"studio\" was built in the courtyard of Edison's laboratory.
On April 14, 1894, the first kinetoscope theater opened in New York City.
On April 23, 1896, the first film was shown at Coster-Byell's Concert Hall in New York using the \"Veta projector\
In 1902, the use of a new battery as a vehicle power test, travel 5000 miles, each charge, can go 100 miles, success.
In 1903, Edison's company produced its first feature film, Train Robbery.
In 1909, ten years of battery research was finally successful. Made of fax telegraph. Obtained raw material machine, fine grinding machine, long kiln design patents.
From 1910 to 1914, he completed the disc phonograph, which did not damage the record and the steel record. Complete the sound movie machine.
In 1910, the \"disc disc\" was invented.
In 1912, he invented the \"sound film\" and developed the phonograph.
1914-1915, the invention of carbonic acid synthesis manufacturing method, and the phonograph and the speaker as a remote writing machine, one telephone can automatically record each other's speech. Manufacture benzene, indigo oil, etc.
From 1915 to 1918, he completed 39 inventions, the most famous of which are torpedo mechanism, flamethrower and underwater periscope, etc. In 1927, he completed a long time record.
