Incandescent lamps, along with the growth of the 80s, have played an indelible role in people's lives. Although incandescent lamps have begun to gradually "retreat", its light still remains in our hearts. The following decoration home decoration network Xiaobian will help you to revisit the incandescent lamp!
An incandescent lamp energizes the filament to an incandescent state, using an electric source that emits visible light using thermal radiation. Since 1879, TA 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. In 1959, the United States developed a tungsten halogen lamp with a small volume and low extinction on the basis of incandescent lamps. The development trend of incandescent lamps is mainly to develop energy-saving bulbs. Incandescent lamps of different uses and requirements have different structures and components. Although the light efficiency of incandescent lamps is low, the light color and light collecting performance are good, and it is the largest and most widely used electric light source.
How about incandescent lamps:
Its advantages:
Incandescent lamps have low power, low power consumption, and are also very cheap; they have various forms such as orientation, scattering, and diffusion; they have good lighting effects. It is versatile and has many varieties of colors.
Incandescent lamps have a short life span. Compared to other energy-saving lamps, fluorescent lamps consume one-fourth the power of incandescent lamps at the same brightness. With the emergence of various energy-saving lamps, the power consumption of incandescent lamps is even greater.
The above is the relevant knowledge of the incandescent lamp introduced by the decoration home decoration network Xiaobian, I believe that even if the incandescent lamp "retreats the rivers and lakes", its brilliance will always illuminate us! More relevant and exciting, please don't forget to pay attention to our life encyclopedia!
