history of LEDs

LED stands for light-emitting diode, and many believe LED lights are a 21st-century invention. LED lights have a low energy consumption, small size, and longer lifetime than incandescent lights, and because of this, they are much more versatile. Let’s talk about the history of LED lights.

A brief History of LEDs

 

The first LED light was invented in 1927 by a Russian inventor. He published a paper on his findings, but there was little progress for decades afterwards. In 1962, the first light-emitting diode was created. This is the first LED with a visible wavelength, and it marks the beginning of the start of industrially produced LED lights.

 

At this point, things moved fast, and in 1971, LEDs in green, orange, and yellow were created. Blue LEDs were created in 1993, along with an LED light in the green spectrum. The white LED was created in the same year, becoming the most popular LED to date.

 

The next notable advance for LED lights was in 2006, when the 100 lumens per watt (lm/W) LED light was first created. The only thing that outmatches the LED’s 100 lm/W is the gas discharge lamp. Four years later, LEDs had graduated to 250 lm/W, and the progress hasn’t stopped there. Today, LED lights are created for all sorts of applications, including plants and livestock.

 

When they first hit the market, LED lights were incredibly expensive, but they have lowered in price since then. However, even at their lowered price, they’re still more expensive per item than incandescent bulbs. Even with a higher initial cost, LED lights are more cost-effective and environmentally friendly compared to their incandescent counterparts. They also last ten times longer, so if you’re looking for a quality lightbulb for your home or business, LED lights can give you all the brightness of incandescent bulbs without the excess heat, energy waste, or cost.
