National LED Light Day – October 7, 2024

National LED Light Day, held on October 7, was first recognized by Bridgelux, which founded the day in 2016. The aim of the occasion was to celebrate the great discovery and creation of LED lights, and how they are used in everyday life. However, over time, the day also began to highlight the numerous advantages LED lights can have on the environment — which is now facing a tragic energy crisis. Want to contribute to the positive future of mother Earth? Celebrate the day with great fervor and spread awareness about all the advantages of LED lights.

History of National LED Light Day

Like every great invention, LED lights took a long time to be invented and then marketed to the world. This is because mankind tends to reject any innovation that they are unable to understand, and it may take them a decade or so to realize just how essential the invention is. The first LED light was created by Russian inventor Oleg Losev in 1927, but nothing was done about the research until much later. Though Oleg had distributed his discovery in Soviet, German, and British scientific journals, his research went unnoticed until the mid-90s. In 1939, Zoltan Bay and Gyorgy Szigeti created the first-ever type of LED and patented the device.

The LED in its real form was finally created in the late 1950s and, by the 1960s, only the red-colored light was available. This was the time when William Shockley filed a patent for an infrared LED, and Nick Holonyak created the first practical visible-spectrum LED. This was just the start. In 1968 Hewlett Packard began to use LEDs in calculators. Furthermore, more experiments were made with LED colors, and M. George Craford, invented the first-ever yellow LED in 1972. However, it wasn’t until 2006 that a white LED was created by Shuji Nakamura. This discovery led him to win a Millennium Technology Prize. It also changed our lives since the white LED can now be spotted in kitchens across the world. By 2019, homes all over the world had switched to LED lighting.
