International Day of Light 2024: International Day of Light is celebrated every year on 16 May. The day is dedicated to recognizing the contributions of light and light-based technologies in various fields and areas, including arts and culture, education, medicine, communications, science, and sustainable development.
Everyone should celebrate the day this year. The day is observed by the United Nations every year. It is also administered by UNESCO’s International Basic Science Programme (I.B.S.P.).
International Day of Light 2024: History
The day dates back to 1802 when Humphrey Davy invented the electric arc lamp, an early predecessor of the modern electric bulb. Davy's invention was a significant step forward in the history of light, making it possible to produce light for the first time in a practical way.
However, the arc lamp was not practical for everyday use due to its high brightness and susceptibility to burnout. In 1815, Joseph Swan solved this problem by inventing the miner's safety lamp, which used cheap carbonized paper filaments to produce light. Swan's invention was also impractical for everyday use, due to the inefficiency of its vacuum pumps.
In the early 1960s, Nick Holonyak, an employee at General Electric, accidentally invented the red LED light. Holonyak's invention was patented in 1965, and in 1990, the blue LED was created by Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura. The blue LED won the 2014 Nobel Prize in Physics for its breakthrough.
