In fact, before Edison, many people also made many contributions to the invention of electric light. 180 1 year, British chemist David electrified platinum wire to glow,181year, and he also invented an electric candle, which was illuminated by an arc between two carbon rods. 1854, Henry Goebbels invented the first practical incandescent lamp with a carbonized bamboo filament which was electrified under a vacuum glass bottle.
1874, two electrical technicians in Canada applied for a patent for the electric lamp, which was filled with helium gas under the glass bulb, and was illuminated by a charged carbon rod, and later sold to Edison. Edison founded "Edison Electric Lighting Company" on 1879. Incandescent lamps were listed on 1880 and successfully maintained in the laboratory 1200 hours. Since then, mankind has entered the era of electric lighting.
