The incandescent light bulb, since its fairly recent invention, has quickly become an essential part of modern technological life as we know it. It took many years to create a practical light bulb despite the simplicity of its structure. I believe a majority of us take them completely for granted and are an integral part of life. Early humans knew the sun as a source of light, and when the sun set, they knew the moon and stars. As his intelligence increased and he learned about the world he lived in, he became associated with fire. Fire could be used for warmth, cooking, protection and lighting. Man lived with this for years, developing and improving the way fire was created and burned for illumination, until 1809 when one man, an English chemist named Humphrey Davy, began research. of a usable incandescent light source using electricity. . Using a high-power battery to induce a current between two high-power bands, it produced intense incandescent light, known as the first arc lamp. Although a first step, it was not yet a practical light source. The first known attempt to make an actual light bulb didn't take place until 1920, when Warren De la Rue enclosed a coil of platinum wire in a vacuum tube and passed an electric current through it. Even though a platinum bulb wasn't practical, the idea behind its design was. A metal with a high melting point to achieve a high temperature and therefore bright light, as well as an evacuated tube which contained fewer particles to react with the metal and therefore extended bulb life. Over the next decades, scientists worked to create their “effectiveness.” " light bulb. Their main obstacle was finding a low-cost, long-lived, high-temperature filament that would glow with high intensity. In 1879, two scientists, Joseph Wilson Swan and Thomas A Edison, made independent breakthroughs for a longer lasting incandescent bulb due to their use of a carbon fiber filament derived from cotton This lasted a maximum of 13.5 hours. In 1880, Edison also developed a filament derived from bamboo that lasted up to 1. 200 hours was good, but to create a truly efficient bulb, something different was needed: creating a filament with very high temperatures but without degeneration or heat loss. Many elements were experimented with, some of the. most popular being carbon, osmium and tantalum.
