More model informationAn incandescent lamp is an artificial light source in which light emits a glowing body heated by an electric current to a high temperature. As a body of incandescence, a spiral of refractory metal (most often tungsten) or a carbon filament is most often used. In order to avoid oxidation of the body of incandescence upon contact with air, it is placed in an evacuated flask or a flask filled with inert gases or halogen vapor. -link removed-
