The Discovery of LEDs
Light emitting diodes are original conceptualized along with light emitting diodes by Nick Holonyak Jr back in 1962.
The Next Phase
Of LED Lighting: Nanotechnology
LEDs make for some great lighting solutions. In fact, 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. They are so small that 10,000 of them could fit on the width of a human hair. 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 Jacob Haibt created the first blue light-emitting diode (LED) in 1994 that things really started getting interesting. It was a plastic device that fit into the standard screw-in light bulb socket. However, Haibt’s LED wasn’t bright enough to replace a standard incandescent light, so the concept didn’t spread.
