"Beat" 3 monitors America discovered 113 years of incandescent lamp

According to U.S. media reported on December 15th, the United States Livermore fire station has been a century old care of people who care. The incandescent light bulb has been working for 113 years since 1901.

In the past 113 years, in addition to power failure, the bulb only in 1976 and in 2013, each time out. In 1976, when firefighters to the light moved, in order not to damage the bulb, they did not use the screwdriver to unscrew lamp, but cut off the rope, the police and fire vehicles escorted into other places. The whole process lasted 22 minutes, the light bulb went to a new place and went on working.

It is understood that the Livermore bulb is a manual blown incandescent lamp, built-in carbon filament. The researchers will imitation hundred years of bulb and ordinary light bulbs were compared and found that different Livermore bulbs and ordinary light bulb is mainly manifested in two aspects: one is the thick filament filament than the average 8 times; second, the hundred years of the bulb may be made from semiconductor carbon filament. The higher the conductor temperature of the ordinary bulb, the lower the electrical conductivity, but the higher the conductor temperature of the century, the higher the electrical conductivity. However, scientists have not yet been able to figure out the exact reason for the longevity of the Livermore bulb.

Although it is not clear that the exact date of the start of the bulb, but firefighters will be June 18th each year as its birthday". In order to observe the 100 years of light bulbs, specially placed around the real-time monitor. Interestingly, the tenacious life of a century lamp has so far been defeated 3 monitors.
