Remember the longest life light bulb in the world? Since the beginning of 1901, it has been working continuously for 113 years and even blew up three monitors.
Below we introduce that although this light bulb is not so forceful, it is said that it can also be used for 40 years and the brightness is much higher than that in the above.
The British inventor Jake Dyson tried to break the embarrassment of light bulbs. He developed an LED light bulb that can be used continuously for 40 years after 12 hours of use.
Conventional light bulbs use an inert gas to suppress the principle of sublimation of tungsten filaments. Although the operating temperature is increased and the light is brighter, this does not only shorten the life of the light bulb, but does not extend the lifespan.
The secret of this light bulb's long life is temperature control. Jake Dyson installed a heatsink next to the bulb to keep the temperature of the bulb below 55 degrees.
The price of such a light bulb is naturally not cheap, asking for a price of 2,000 US dollars, or about 12,400 yuan, and it can buy two iPhone 6 Plus in China.
