Imagine the world without any light. Light is a part of our daily lives. Light bulbs are essential for our daily lives. It would be difficult to live without it. We would live in darkness if the lightbulb didn’t exist. Light bulbs were invented by many people, who improved them and created many designs over time.
Thomas Edison was a great inventor. He thought of a lot when he was improving the light bulb. Edison believed he could make better vacuum cleaners. He thought that he might be able make a light that was incandescent. Edison described the lamp as “a light bulb that emits light through incandescence made of carbon filaments with high resistance and attached to metallic cables as specified” (Buranelli, 49). Edison has made numerous improvements to the lightbulb over the years. Edison tried platinum but had no success. He then turned to carbon. Edison replaced gas lights with electric lighting. Edison began to use the lightbulb in 1870. Edison is a famous inventor. Edison’s first invention was made when he turned 21 (Pagan). Edison was a prolific inventor. He had 1,093 inventions that he patented either alone or with others. Edison’s very first invention was a voting counter.
The United States Office of Patents in Washington D.C. discovered that Edison was alone in the field incandescent incandescent light bulbs (Buranelli). It took a lot of tries and many different designs to perfect the lightbulb. Since its creation, the light bulb has undergone many changes. Today’s filaments are made of coiled, tungsten. The lightbulb did not originate with a single individual. Perfection is achieved by many people making small improvements. The lightbulb works in a particular way. The majority electrical energy is used to warm the wire. The filament (wire) could glow if a generator sends an electric current through it. The design of the lightbulb changed many times. Edison covered a thread of cotton in powered-carbon to create a filament (a cable) that would last the longest (Buranelli, 49). For many, many years, filaments from bamboo were used in millions of lightbulbs (Pagan).
Every lightbulb is contained in a glass ball (“Incandescent Lamp” 1089). Incandescent lamps are available in a wide range of sizes and shapes. The light bulb is essential to our way of life. Light bulbs use energy to produce light. It can also be used to generate heat and light (see “Incandescent Light”, page 1088). Energy is available in a variety of forms including heat, mechanical, electrical and magnetic energy, sound or chemical energy. In 1835, the first constant-light bulb was shown. Incandescent was the predominant light source in the early days. Light bulbs are a major source of energy. An object moving means it has energy.
The different ways that energy occurs has led us to know its existence. Inventions are everywhere, and the lightbulb is among the biggest. Edison worked hard to improve the lightbulb. Edison once said: “Our biggest weakness is to give up.” “The only way we can see is to keep trying.” Edison stopped trying and we wouldn’t have the lightbulb today.
