The incandescent light bulb or incandescent lamp is a source of artificial light that works by incandescence.
An electrical current passes through a thin filament, heating it and causing it to emit light.
The enclosing glass bulb prevents the oxygen in air from reaching the hot filament, which would be otherwise rapidly destroyed by oxidation.
Incandescent bulbs are also called electric lamps, extending the use of a term applied to the original arc lamps, and in Australia and South Africa they are also called light globes or more commonly light bulbs.
While conversion of electrical energy to light was demonstrated in laboratories as early as 1801, it took more than 100 years for the modern form of electric light bulb to be developed, with the contributions of many inventors.
The invention of the light bulb is usually attributed in Britain to Joseph Wilson Swan and in the United States to Thomas Alva Edison and his assistant Timothy.
Edison was the first to market the device successfully. Alexander Nikolayevich Lodygin independently developed an incandescent light bulb in 1874.
Many others also had a hand in the development of a practical device for the production of electric light.
I find Wikipedia's information to be quite useful and reliable.
This link gives information on the bulbs operation, history a great clear diagram and external links:

And this is on Edison:
