The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light. He was neither the first nor the only person trying to invent an incandescent light bulb. In fact,...
In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn’t produce it for long and was much too br...
1906 - The General Electric Company were the first to patent a method of making tungsten filaments for use in incandescent lightbulbs. Edison himself had known tungsten would eventually prove to be...1910 - William David Coolidge of General Electric improved the process of manufacture to make the longest lasting tungsten filaments.1920s - The first frosted lightbulb is produced and adjustable power beam bulbs for car headlamps, and neon lighting.1930s - The thirties saw the invention of little one-time flashbulbs for photography, and the fluorescent tanning lamp.Modern incandescent bulbs are not energy efficient – less than 10% of electrical power supplied to the bulb is converted into visible light. The remaining energy is lost as heat. However these inefficient light bulbs are still widely used today due to many advantages such as: 1. wide, low-cost availability 2. easy incorporation into electrical syst...
Learn how the electric light was invented by several inventors before Thomas Edison created the first commercially practical incandescent bulb in 1879. Explore the timeline of lighting history and the future of LED technology.
The "Centennial Light" is a light bulb that is accepted by the Guinness Book of World Records as having been burning almost continuously at a fire station in Livermore, California, since 1901. However, the bulb emits the equivalent light of a four watt bulb.
