NATIONAL LED LIGHT DAY
October 7 may be an unusually illuminating day considering it is National LED Light Day.
We are all born as incredible detectors of light, intuitively seeing differences in color and brightness. Lighting professionals know that much of human sensation is visual. People respond emotionally to light and color, using its consistency to draw us in, like moths to a glowing light. The power of LED lighting affects all of us in emotional, economic, and environmental ways.
Emotion
Unlike other light sources, LEDs have the ability to create a more appealing display for a variety of environments. Let’s say you drive by two gas stations. Station A is illuminated throughout by bright white LED lights, while Station B’s illumination varies from yellow to white and one panel is dim. You will likely go to Station A because its color consistency feels comforting, clean, secure and high-quality, even if you aren’t conscious of that decision.
Economy
LED lights help save on our energy costs. The low power consumption, high reliability and long lifespan allow us to realize significant energy savings and maintenance reduction over the lifetime of an LED fixture.
Environment
The fewer LED bulbs changed means there are fewer bulbs thrown away. LED bulbs have a much smaller impact on the environment than other light sources. Also, because LEDs use electricity very efficiently, greenhouse gas emissions are reduced.

HISTORY
On October 7, 2014, Isamu Akasaki, Hiroshi Amano and Shuji Nakamura received the Nobel Prize in Physics for the development of blue light-emitting diodes. To understand why this was a Nobel-worthy achievement, we must know the history of LED lighting.
The earliest LEDs created in the late 1950s and early 1960s produced only a red colored light. Slowly researchers developed other colors, but blue was the tricky one. Its shorter wavelength proved harder to reproduce. With Akasaki, Amano and Nakamura’s invention, white LEDs were now possible.

founded National LED Light Day in May of 2016 to recognize one of the most important scientific achievements in recent history, as well as celebrate the advancements of this versatile technology. The Registrar at National Day Calendar approved the day in 2016.
