The Discovery of LEDs

Light-emitting diodes are originally conceptualized along with light-emitting diodes by Nick Holonyak Jr back in 1962.

LED lights are created since the Silicon Diode was invented, but the LED lights gained popularity in the 20th century, and the market was able to grow exponentially.

The Next Phase

LEDs make for some great lighting solutions. The technology has been around for decades and is being used in thousands of different products, from televisions to traffic lights.

LEDs are attractive because they save energy, emit less heat, and last longer than other conventional devices. But what you may not know is that the possibilities for LED lighting are just getting started.

The technology behind LEDs is going through some changes that will make LEDs even more efficient. Researchers at the University of California in Los Angeles, for example, have built an LED that produces light by passing electricity through tiny dots of semiconductor material made with nanotechnology. The new LED device promises 10 percent greater efficiency.

Nanotech LEDs are the future of energy savings. Nanotechnology is the science of the very, very small. At the molecular level, materials have different properties. Nanotechnology takes advantage of this to create a new technology that’s more than the sum of its parts.

The research at the UCLA lab employs nano-sized structures, much smaller than the wavelength of visible light. This allows researchers to harness heightened effects and make different kinds of light.

LEDs and The Current Situation

Light-emitting diodes (LEDs) have existed for over a century, but they weren’t developed for consumer-level, indoor lighting. Rather, they were first used in the early 1900s as indicators in laboratory instruments. They didn’t appear in consumer electronics until the 1970s when they were tinkering about in calculator backlights.

It wasn’t until Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura created the first blue light-emitting diode (LED) in the early 1990s that things started getting interesting.


LEDs have been around for some time, and they are currently gaining even more popularity. Soon, we might not be talking anymore about when they were invented, but how did they become the no1 lighting solution for
almost every daily necessity.
