The purpose of a light bulb is to produce light when the Sun is not shining!
Another answer
Light bulbs were invented to help people to see things better in gloomy or dark conditions and to be able to see their way if they wanted to go somewhere at night. Having any kind of artificial light - not just light bulbs but flaming torches, oil lamps, etc. - meant people could stay up for longer every evening.
Before any kinds of lighting were invented people used to have to go to bed early - especially in the seasons of the year when night time is longer than day time - because, if they stayed up after it got dark, they weren't able to read books or do any work, etc.
