The incandescent lamp has been used worldwide for more than 100 years since its invention. Incandescent lamps are used to directly add AC mains to the tungsten wire resistors to make them glow and illuminate, thus illuminating the darkness, enabling hundreds of millions of people around the world to have a bright and happy life with electric lights at night, and the convenience of working.
An incandescent lamp is an electric light source that energizes the filament to an incandescent state and emits visible light using thermal radiation. Since 1879, Thomas Edison of the United States has made carbon fiber (ie carbon filament) incandescent lamps. Since the filament material, filament structure and filling gas have been continuously improved, the luminous efficiency of incandescent lamps has also increased accordingly. However, the luminous efficiency of incandescent lamps and other light point parameters are worse than new light sources such as energy-saving lamps and tungsten halogen lamps, and are gradually being replaced by new light sources. From October 1, 2012, China will ban the import and sale of more than 100 watts of ordinary lighting incandescent lamps.
