Technical

Tungsten is used in almost all incandescent light bulbs because it has a high melting temperature, making it conducive to producing visible light. In early light bulbs, the air was removed to create a vacuum to prevent combustion. However, as a result of the high temperature, tungsten atoms detach from the filament and cover the glass. The filament disintegrates over time and reduces the life of the bulb. Modern light bulbs are manufactured with inert gases, such as argon, which significantly reduces the loss of tungsten. Incandescent light bulbs produce the majority of their energy in the form of infrared light; approximately 10% of light is produced in the visible spectrum (Harris, "How Light Bulbs Work"). The light bulb was invented over a period of time by many inventors, however its invention is credited to Joseph Swan and Thomas Edison, who did similar work around 1878 and 1879 (Grabianowski, "10 Inventions that Changed the World").
