Among the previous Nobel Prize winners in physics, the most successful one should be Niels Gustav Dahlen. His automated lighthouses and buoys are considered to be the most innovative in history. A winner of water.

The Nobel Prize was established in 1895 with part of the legacy of the famous Swedish chemist Alfred Bernhard Nobel (31 million Swedish kronor) as a fund. The Nobel Prize is considered the most important award in all award fields. The Nobel Prize was originally divided into five categories: physics, chemistry, physiology or medicine, literature, and peace. The Nobel Prize was first awarded in 1901. In 1968, on the occasion of the 300th anniversary of the establishment of the Swedish National Bank, the Swedish National Bank donated a large amount of funds to the Nobel Fund and also added the "Swedish National Bank Memorial Nobel Prize in Economic Sciences".

Niels Gustav Dahlen, a Swedish physicist and inventor, whose research field is the application of mechanical engineering. In 1912, he invented the ignition beacon that combines the functions of a burning point beacon, a burning point buoy and a battery. He won the Nobel Prize in Physics for his automatic adjustment device. After 1907, Darren's invention was used in many coastal countries. In September 1912, Darren was blinded by an explosion during the experiment, but he still continued the experiment. Until his death, Sweden later awarded the Nobel Prize in Physics to Darren, with his brother accepting the award on his behalf.

Darren's Nobel Prize winning caused controversy. It was believed that Darren's invention was neither a major theoretical contribution nor a major experimental discovery. However, we cannot deny Darren's contribution to physics.
