why was the invention of the light bulb so important

by Sophia Weissnat Published 3 years ago Updated 3 years ago

The electric light bulb has been called the most important invention since man-made fire. The light bulb helped to establish social order after sundown, extended the workday well into the night, and allowed us to navigate and travel safely in the dark. Without the light bulb, there would be no nightlife.

Thomas Edison is the person whom historians often credit with devising this invention, along with many other innovations. Other historians say that Edison didn’t invent the lightbulb, but helped transform the original into the lightbulbs we know today.

What was the first light bulb ever made?

Edison Light Bulb, 1879 Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention—the light bulb, the first practical electric incandescent lamp. The light bulb creates light when electrical current passes through the metal filament wire, heating it to a high temperature until it glows.

When was the first electric light bulb invented?

In 1835, the first constant electric light was demonstrated, and for the next 40 years, scientists around the world worked on the incandescent lamp, tinkering with the filament (the part of the bulb that produces light when heated by an electrical current) and the bulb’s atmosphere (whether air is vacuumed out of the bulb or it is filled with an inert gas to prevent the filament from oxidizing and burning out). These early bulbs had extremely short lifespans, were too expensive to produce or used too much energy.

Who invented the electric light?

Humphry Davy invented the first electric light in 1802. He researched, tested and did experiments with electricity and most notably invented a type of electric battery. During one of his experiments, he connected wires to one of his batteries and a piece of scrap carbon. Once the electrical circuit was completed, the carbon heated up and began to glow which as a result produced both heat and a great deal of light. His invention was known as the Electric Arc lamp and because it had a short life and was abnormally bright, it was never deemed practical for household or industrial use as every day lighting. Humphry’s invention was not a total failure and many years later become the preferred light source used in the movie theater film projectors. It took many years for other inventors to take Humphry’s idea and turn it into a practical, working product.

Who invented the carbon rod lamp?

When did Thomas Edison start making lamps?

In 1878, Thomas Edison began serious research into developing a practical incandescent lamp. Edison filed his first patent on October 14, 1878 for “Improvement In Electric Lights”. While waiting for the patent to be approved, Edison continued to test and improve the design by experimenting with many types of materials to be used as filaments. By November 4, 1879, his discoveries were so significant that he was able to file another U.S. patent for a electric lamp that used “a carbon filament or strip coiled and connected … to platina contact wires.”. The filament was made from a piece of carbonized thread similar to what Joseph Wilson Swan had been working on many years early. It was Thomas Alvin Edison’s practical approach and improvements in the design that made his electric light bulb the first truly viable commercial product.
