The Lightbulb

The Invention that Lit up the World

Where it all Started

Thomas Edison set off in a hope to find a form of electric powered lighting. 1878 was the year he was embarking on the journey of creating the first successful incandescent light bulb. The idea of having consistent indoor light was a dream indeed, but it was not a impossible dream. Using carbon filaments, he was able to create a practical light bulb that could reproduced quickly and easily.

How it Works

A fluorescent light bulb consists if a glass tube that holds in mercury vapor under pressure. This is contained in side of a chemical gas that most likely is argon. The tubes could be any shapes depending on the size, shape, and wattage of the bulb. When an electrical current is sent through the tubes in combines with the argon or other chemical in the bulb, it sends off a light source that combines to ultraviolet rays in the air.

How the Light Bulb makes our Faces Light Up

The light bulb started off at only holding light for a couple hours. Now, LED lights and other light bulbs can last hundreds and even thousands of hours. Imagine, we went from walking around with candles, maybe torches, and other burning light sources in order to light our way. What if you entered your house one day and instead of flipping a switch you lit a candle to get to your room. Without the light bulb, we wouldn't have the beautiful city scenes that we have today. We wouldn't be able to drive at night because there would be no light to assist us to see. We wouldn't be growing as fast as humans in our technological journey without the light bulb.
