Remember the longest-lived light bulb in the world? It has been working continuously for 113 years since 1901, and even messed up three monitors.
Below we introduce this light bulb, although not so powerful, but it is said that it can also be used for 40 years, and the brightness is much higher than the above.
Jake Dyson, a British inventor, tried to break the current state of the light bulb. He developed an LED bulb that can last for 40 years if used for 12 hours a day.
Ordinary bulbs use inert gas to suppress the principle of tungsten sublimation. Although the operating temperature is increased and the lighting is brighter, this only means that the life of the bulb is not shortened, and the life cannot be extended.
The secret of this bulb's long life is temperature control. Jake Dyson placed a radiator next to the bulb to keep the bulb temperature below 55 degrees.
The price of such a powerful light bulb is naturally not cheap. The asking price is 2,000 US dollars, about RMB 12,400. You can buy two iPhone 6 Plus in China.
