An incandescent light bulb is an electric light with a wire filament heated to such a high temperature that it glows with visible light (incandescence). The filament is protected from oxidation with a glass or fused quartz bulb that is filled with inert gas or a vacuum. It is used to illuminate the space.
Thomas Edison is widely considered to be the inventor of the incandescent bulb, but there are a number of people who invented components and prototypes of the light bulb well before Edison did.
One of those people was British physicist Joseph Wilson Swan, who actually received the first patent for a complete incandescent light bulb with a carbon filament in 1879. Swan’s house was the first in the world to be lit by a light bulb. Edison and Swan merged their companies and together they were the first to design a bulb that was commercially viable.
I think that an incandescent light bulb is useful because the sun is almost the only one natural illuminant. This invention allow people work
