On May 16 each year, the International Day of Light is observed to recognize the contributions that light and technologies based on light have made to a variety of fields and areas of life, including the arts, culture, education, medicine, communications, science, and sustainable development. Did you know that Humphrey Davy created the first electric lamp in the world in 1802? Worldwide Day of Light honors the commemoration of physicist and designer Theodore Maiman's most memorable fruitful laser activity in 1960. The International Basic Science Programme (I.B.S.P.) of UNESCO is in charge of managing the day, which is observed by the United Nations. Events and forums both within and outside the scientific community are held worldwide to commemorate International Day of Light.
HISTORY OF THE INTERNATIONAL DAY OF LIGHT Since antiquity, humans have utilized a variety of light-producing materials, including gas, candles, hollow rock, shells, and wood soaked in animal fat and oil. The advanced history of light started with the creation of the electric light. The light bulb was invented long before Thomas Edison patented it, contrary to popular belief. Only the commercial production of light bulbs was made possible by Edison. In 1802, Humphrey Davy designed the electric curve light, an early ancestor of the brilliant electric bulb, by associating voltaic heaps to charcoal cathodes. In any case, the circular segment light was not a reasonable wellspring of lighting as it was excessively brilliant for homegrown or work utilizations, and it wore out rapidly. In 1815, the miner's safety lamp and street lighting in several European cities, including Paris, were both made possible by this invention.
In 1850, Joseph Swan came up with a solution to one of the issues that subsequent inventors of electric lamps had to deal with: the lamp's filament's cost-effectiveness. Swan utilized inexpensive carbonized paper filaments in place of platinum filaments. He showed off his electric lamp at a lecture in Newcastle, England, in 1878, and he patented it in the UK. Swan's creation, similar to Davy's curve light, was unrealistic for regular use because of the shortcoming of its vacuum siphons. Edison improved Swan's electric lamp after discovering the flaw and presented his light bulb in December 1879. Swan developed an electrical lighting business in England by imitating these advancements. Edison unsuccessfully attempted to sue Swan for patent infringement.
Edison and Swan later joined forces to form Edison-Swan United, which eventually became the largest light bulb manufacturer in the world. The red LED light was invented by accident and patented by General Electric employee Nick Holonyak in the early 1960s for use as a light fixture. The blue LED was developed by Japanese and American researchers Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura in the early 1990s. For their work, they received the 2014 Nobel Prize in Physics.
As a result, white LEDs were created by scientists. With the ability to wirelessly illuminate homes and streets with the help of smartphones and AI voice commands, lighting is becoming increasingly sophisticated. Halogen, LED, and OLED alternatives are taking their place in place of incandescent light bulbs, which are also being phased out.
Do you be aware?
The Worldwide Day of Light denotes the commemoration of the primary fruitful activity of laser in the year 1960, led by notable physicist and specialist, Theodore Maiman.

The background of the International Day of Light: In 2015, the United Nations declared the International Year of Light and Light-Based Technologies (IYL 2015), with the goal of drawing attention to the achievements of light science and the numerous applications it has found. The occasion was an incredible achievement and following it, the nations of Ghana, Mexico, New Zealand and Russia set forward a goal before the UNESCO Leader Board supporting to yearly notice Global Day of Light. At the Board's 200th meeting the goal was embraced on September 19, 2016 at the UNESCO HQ in Paris, France. At the 39th meeting on November 7, 2017, the Board choice was authorized by the UNESCO General Gathering, and the primary Worldwide Day of Light was hung on May 16, 2018.
