Incandescent

Chinese name: Incandescent lamp English name: incandescent lamp

Definition 1: An electric light source that emits electricity by heating a light emitter to an incandescent state. Respective disciplines: Electric power (a subject); distribution and electricity (two subjects)
Definition 2: A thermal radiation source with current flowing through the light emitter to make it glow. Respective disciplines: mechanical engineering (a subject); instrumentation components (two subjects); instrument light (three subjects)

The incandescent lamp heats the filament to an incandescent state and utilizes thermal radiation to emit an electric light source that is visible. Since the United States' TA Edison made carbon filament (ie, carbon filament) incandescent lamps in 1879, people have continuously improved the filament material, filament structure, and filling gas, and the luminous efficiency of incandescent bulbs has also been correspondingly improved. In 1959, the United States developed tungsten bulbs with small volume and decay on the basis of incandescent lamps. The development trend of incandescent lamps is mainly the development of energy-saving light bulbs. Different uses and requirements of incandescent lamps, their structure and components are not the same. Although the light efficiency of incandescent lamps is low, but the light color and light collection performance is good, it is the largest output and the most widely used electric light source.
