The Bulb, originally used in the United States, is called Henry goebbels. The most famous inventor was Thomas Alva Edison, an American scientist who famously tried out the light bulb on October 21, 1879.
In the process, Thomas Alva Edison carefully analyzed the gas and arc lights of the time, and his main focus was to find a heat-resistant material. It is heated by an electric current to the point of being heated to a degree that gives off a glowing light without breaking or melting. He happened to find that the cotton thread burned to ashes in the air, and that the carbon thread shone in the treated glass ball. Unfortunately, the light lasted only a few minutes before it disappeared. He mistakenly abandoned the experiment and instead experimented with 1,600 different heat-resistant materials, including cesium, nickel, platinum (platinum) and platinum (iridium) alloys.
