Nanotechnology in LED Productionmbedewy
Nanotechnology is basically the manipulation of a matter or several matters on a molecular scale. The theory of the technology has been announced since the 1960’s, but major researches and developments started during the 1980’s. Its introduction to LED production is bringing quality achievements both in lighting solutions and for displays.
LEDs are the most energy-efficient lighting solution on the market, since LEDs convert the majority of energy into light. Still, about 20% of the light emitted by the diode is lost due the high refractive index of LEDs (a certain percentage of the light is reflected back inside the diode and is not emitted eventually). This rate usually depends on the components of the diode. To get this light otherwise lost within the diode, researchers – and recently adopted by manufacturers – used nanotechnology and created microscopic holes (roughly 400 times narrower than a human hair) on the surface of the diode, usually hundreds of thousands of holes on a single diode.
