Since the invention of incandescent lamps by Edison, tungsten has been used in the field of lighting for more than 100 years. From the initial heat radiation source to the more efficient gas discharge source, the core position of tungsten in the electric light source has never wavered. The emergence of electroluminescent sources has subverted the general understanding of electric light source materials, but tungsten as a core material for electric light sources will exist for a long time. Tungsten materials are also widely used in various electric vacuum devices, including magnetrons, high voltage rectifiers, and the like.
