I just recently learned that October 7 is National LED Light Day. Why have a national day just for a type of light? I was wondering the same thing. It turns out, there are lots of reasons to celebrate LEDs (light-emitting diodes), not the least of which is that, thanks to creative inventors and engineers, we enjoy LED lighting as we go about many of our everyday activities. Which is why Bridgelux, Inc., a company that designs patented LED lighting solutions, founded National LED Light Day in May 2016 to celebrate the history and advancements of the LED light.
