The blue LED made the white LED lighting, and the white LED in turn helped the blue LED to win the 2014 Nobel Prize in Physics. It can be seen that its meaning is extraordinary Straw Hat With Lamp Beads. We can do a calculation to further understand the changes brought to our lives by the blue LED under the Nobel halo. According to incomplete statistics, the world consumes about 200 billion kilowatt-hours of electricity each year, of which about 19% is used for lighting. If all incandescent lamps (about 10% electro-optical conversion rate) and fluorescent lamps (about 30% electro-optical conversion rate) are replaced with White LED energy-saving lamps (electric-to-optical conversion rate of more than 50%), then the world will save at least 1.520 billion kilowatt-hours of electricity each year, which is equivalent to reducing coal consumption by about 500 million tons, reducing carbon dioxide emissions by about 1.3 billion tons, and reducing sulfur dioxide emissions by about 420 Led Bulb. Million tons. These tangible data demonstrate the great wisdom and great energy of Xiaoxiao Blu-ray Core. We have reason to believe that the white light lit by the blue core will surely illuminate Wanjia Red Light Emitting Diode!
