Answers
Answer:
Thomas alva adison invented bulb light
1809: Humphry Davy attached a fine charcoal strip between the ends of the wires connected to a battery. This is considered to be the first light bulb.
1840: Warren de la Rue put a coiled platinum filament inside a sealed vacuum tube. He created a long-lasting light, but it was far too expensive.
1875: Henry Woodward and Matthew Evans patented the light bulb, which was basically the same as that of three decades before.
1879: Joseph Wilson Swan presented an enclosed glass bulb, from which all air had been removed, platinum lead wires, and a light-emitting element made from carbon, which did not last very long when actually installed.
1880: Thomas Edison, having purchased Woodward and Evans’ patent, presented a light bulb with a carbonated bamboo filament with a lamp life of 600 hours. This was the first real commercial model.
1913: Irving Langmuir invented neon lights by filling the light bulb with an inert gas.
1997: Isamu Akasaki, Hiroshi Amano and Shuji Nakamura managed to create the first bright blue light-emitting diode (LED) lamp.
Edison only invented the commercial light bulb, the light bulb existed way before Edison.
