Transcript of Light bulb By: Jonathon Skowron and Alexandria Smith


Lightbulb

Thomas Edison, a famous scientists, made a revolution for the future of man kind... the lightbulb. The lightbulb was invented by other people, but they never found a safe prototype until Thomas Edison came along. The safest version was invented in 1879.
At first, people used oil lamps. They were extremely dangerous. Then, the lightbulb was invented. It was much safer and a good source of light. We take the lightbulb for granted now. Back then, people valued the lightbulb. We should too because otherwise most of our other inventions would not exist without it. You wouldn't be reading this without lightbulbs because this computer wouldn't exist. Thereof the lightbulb is a very important invention.
High-frequency power-conversion lightbulbs are one of the innovations. This makes the lightbulb last even longer and it saves power. They MUST be manufactured differently otherwise it won't save power.
