Imagine a world without light. We use light in our daily lives. That's why the importance of the light bulb cannot be overstated. Without it we would have to use oil lamps and candles, and this would be difficult. If we didn't have the light bulb our life would be very dark. The light bulb has had many different inventors and people who have made improvements and many different designs as time has gone on. 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 “an incandescent lamp consisting of a high-strength carbon filament made as described and attached to metal wires, as set forth” (Buranelli 49). Over the years, Edison made many improvements to the light bulb. When Edison had little success with platinum, he turned to carbon (Buranelli 49). Edison used electric light to replace gas lighting. In 1870, Edison removed the metal for the use of the light bulb (“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 Edison's death he had patented either, individually or jointly, 1,093 inventions. Edison's first invention was an electric vote counter. The United States Patent Office in Washington DC found that Edison had no competition in the field of practical incandescent electric lighting (Buranelli). The light bulb was a unique invention that took many attempts to perfect, using different designs and improvements. The light bulb today has many different changes in the way it was first created. Filaments today are now made from rolled tungsten. The light bulb was not created by one person. It takes many people and small improvements to achieve perfection. The light bulb has a certain way and it works. Most of the electrical energy that goes into the bulbs is used to heat the wire. A generator sending a current through a wire going into a vacuum could cause the wire (filament) to become so hot that it glows (Buranelli 46). Numerous design changes were made during the creation of the light bulb. Edison coated a cotton thread with activated carbon to create his longest lasting filament (a thread) (Buranelli 49). For many years millions of light bulbs were sold using bamboo filaments (Pagán). Each light bulb is contained by a glass sphere (“Incandescent Light” 1089). Most incandescent lamps come in different shapes and sizes. Light bulbs are fundamental to our way of life. The light bulb uses energy to produce light. The energy can be used as a source of light and heat (“Incandescent Light” 1088). Energy can have many forms: mechanical, thermal, electrical, magnetic, sonic, chemical and nuclear. The first fixed light bulb was introduced in 1835. Most of the early lights were all incandescent. Energy is an important part of the light bulb. Energy means that an object has been moved.

There have been many inventions in the world and one of the greatest and most important is the light bulb. Edison greatly improved the light bulb, but it took a lot of hard work. Edison once said: “Ours.
