Incandescent bulbs how to extend
Jan 03, 2017

Only reduce the temperature, lowering the temperature of the filament can achieve the purpose of prolonging life. Tungsten wire when working temperature up to 2,700 degrees, lamp light extinguished in less than 1 hour; tungsten filament temperatures below 1700 ℃, the service life can be extended to more than 1000 hours.

However, this is not a good idea. Reducing the operating temperature of tungsten wire, which is reducing its level of incandescent, will reduce the efficiency of incandescent bulbs, far less bright than when the temperature is high.

So the question just staring in front of people: to incandescent bulbs more light, increasing the filament temperature; if you want to reduce tungsten evaporation to extend lamp life and lower its body temperature. This is contradictory.
