How light emitting Diodes could Win a Nobel Prize for Lighting the future

In the Paleolithic period, ancient people began to consciously preserve fire to improve their living environment, not only for cooked food, but also for night light and tools to deal with wild animals. But it wasn't until more than a hundred years ago, when Edison invented the electric light, that our means of obtaining light changed. In 2014, the 2014 Nobel Prize in physics was awarded to three Japanese and American scientists IsamuAkasaki, HiroshiAmano and ShujiNakamur. For "inventing efficient blue light diodes that bring bright and energy-efficient white light sources."

Seek the light of night

What never changes is the natural starlight. But before, only the full moon could light up the earth, and the difference between civilization and not civilization was whether we could use our technology to bring light into the night. In the beginning, we could only burn oil. In western countries, whale oil was used to make candles. In China, it was beeswax or animal pewter. It was not until the oil industry developed that candles were made of cheap long-chain saturated hydrocarbons.
