Imagine a world without light. We use light in our daily lives. This is why the importance of the light bulb cannot be overstated. Without this we would have to use oil lamps and candles, which would be difficult. If we didn't have the light bulb, our lives would be very dark. The light bulb has had many different inventors, people who made improvements, and many different designs over time. Say no to plagiarism.

Edison thought he could use better vacuum cleaners. He thought he could make a lamp that could become incandescent or luminous. Edison described it as “a lamp for giving light by incandescence composed of a filament of carbon and high strength made as described and attached to metal wires as shown” (Buranelli 49). Edison made many improvements to the light bulb over the years. When Edison had little success with platinum, he turned to carbon (Buranelli 49). Edison used electric lighting to replace gas lighting. In the 1870s, Edison eliminated metal for light bulb use (“Incandescent Light” 1088). Edison was a very famous person who made many inventions. Edison made his first invention at the age of 21 (Pagán). At the time of his death, Edison had patented 1,093 inventions, either alone or jointly. Edison's first invention was an electric vote counter. The United States Patent Office in Washington DC found that Edison had no competitors in the field of practical incandescent electric lighting (Buranelli). The electric light bulb was a unique invention that took many trials to perfect, using different designs and improvements. Today's light bulb has many different changes from when it was first manufactured. Today's filaments are now made from wound tungsten. The light bulb was not created by one person. It takes a lot of people and small improvements to achieve perfection. The bulb has a certain way and it works. Most of the electrical energy supplied to the bulbs is used to heat the wire. A generator that sends a current through a wire passing in a vacuum could make the wire (filament) so hot that it will glow (Buranelli 46). When the bulb was manufactured, many changes were made to the design. Edison coated cotton thread with activated carbon to create his most durable filament (a thread) (Buranelli 49). For many years, millions of light bulbs were sold with bamboo (Pagán) filaments. Each bulb is contained in a glass sphere (“Incandescent Light” 1089). Most incandescent lamps come in many different shapes and sizes. Light bulbs are essential to the way we live. The bulb uses energy to produce light. Energy can be used as a source of light and heat (“Incandescent Light” 1088). Energy can take many forms: mechanical, thermal, electrical, magnetic, sound, chemical and nuclear. The first constant light bulb was introduced in 1835. Most early lamps were all incandescent. Energy is an important part of the light bulb. Energy means that an object has been moved.
