The principle of illumination of all incandescent lamps is realized by the principle of object heating and the principle of thermal radiation. The simplest incandescent lamp is to conduct enough current to the filament. When the filament heats up to incandescence, it will emit light, but this incandescence The life of the lamp will be quite short.
At present, the incandescent lamps we have seen use the following various technologies, the purpose of which is to make incandescent lamps have a longer life and more convenient to use: vacuum glass tube (to reduce the degree of oxidation of the filament), light feet (for your convenience) The bulb is inserted into the lamp holder), filled with an inert gas (reducing the degree of oxidation of the filament at high temperatures), and the like.
