Hot-Selling Street Light Housing Supplier introduces how to reduce evaporation and extend the service life of the filament?
Only lowering the temperature and lowering the filament temperature can achieve the purpose of prolonging life. When the working temperature of the tungsten wire is as high as 2700℃, the bulb will be extinguished in less than one hour after lighting; the working temperature of the tungsten wire is reduced to 1700℃, and the service life can be extended to more than 1000 hours.
However, this is not a good way. Decreasing the working temperature of the tungsten filament, that is, reducing its incandescence, will reduce the luminous efficiency of the incandescent lamp, which is far less bright than when the temperature is high.
Therefore, the problem is clearly posed in front of people: if you want incandescent lamps to emit more light, you must increase the working temperature of the filament; if you want to reduce the evaporation of tungsten filaments to extend the life of the lamp, you must reduce its body temperature. This is contradictory.
Due to the large power consumption of incandescent lamps, short lifespan, and performance far lower than the new generation of new light sources, in order to save energy and protect the environment, incandescent lamps have been replaced by some green light sources and have been asked to gradually withdraw from the market. Some countries have banned production And sell incandescent lamps.
